If you simply want a company that produces a ready-made serum, locating a Vitamin C skincare manufacturer is quite straightforward. Where it gets tricky is when you want to create a full line of skincare, select a certain form of Vitamin C or formulate a product that feels like nothing else on the market.
A manufacturer might make a great Vitamin C serum. But they may not have a lot of options for creams, cleansers, masks or other products. Another might specialise in custom formulations but require larger production runs than a new brand can afford to purchase.
I think those differences are more worthy of attention than the size of a factory, or a long list of certifications.
As a manufacturer of skincare products, the first thing I would do is ask the brand what kind of Vitamin C product they want to develop, and what kind of Vitamin C ingredient they want to use, and how much customisation the project really requires. The questions help to find suppliers that fit the product brief rather than just gather quotations from every factory that says Vitamin C.
For this guide, I reviewed 10 Vitamin C skincare manufacturers with publicly documented private label or contract manufacturing capabilities. I looked at their published product ranges, formulation services, minimum order quantities and the types of projects that their manufacturing models appear to support.
The goal is to guide you in creating a shortlist based on your brand requirements, whether you are launching a single brightening product or planning an entire Vitamin C skincare collection.
Below you will find 10 manufacturers to consider for your private label Vitamin C skincare: XIRAN Skincare, RainShadow Labs, Nutrix, Cosmiko, Made By Nature Labs, Trilogy Laboratories, HCP Wellness, Hong Shin Cosmetics, Lessonia, Cellular Cosmetics. They have a wide range of services. Some have relatively low minimum order quantities for pre-made serums, creams and lotions, while others specialise in custom formulation, specialised Vitamin C delivery systems or larger manufacturing programs. So, for a startup, the best supplier choice depends on the product format, formula customisation, MOQ, target market and packaging requirements, not just the locati0n of the supplier.
I did not restrict this list to companies advertising Vitamin C serum making.
The broader goal was to find manufacturers that could support brands in developing Vitamin C-based skincare products, either by providing ready-made formulations or custom development.
I checked four things: documented Vitamin C product lines, private label or OEM/ODM capabilities, publicly available ordering requirements, and suitability for different types of beauty businesses.
I also looked for a distinction between suppliers who sold existing formulations and manufacturers who offered custom research and development.
This is important because private label and custom manufacturing are different animals. A supplier may be willing to take a small order of an already existing Vitamin C cream, but may require a much larger order to create a new formula.
| Manufacturer | Manufacturing Location | Published Vitamin C Product Focus | Public MOQ | Best-Fit Brand Stage |
|---|---|---|---|---|
| 1. XIRAN Skincare | China | Serums, capsule creams, sheet masks and customized skincare | Generally 500~1,000 units for standard products | Growing brands and multi-product lines |
| 2. RainShadow Labs | United States | Serums, lotions, creams and custom formulations | 10 gallons stock; 25 gallons custom | Growing brands and bulk buyers |
| 3. Nutrix | United States | Vitamin C creams, serums and custom skincare | Not publicly specified | Established brands and custom projects |
| 4. Cosmiko | United Kingdom | Vitamin C liquid and oil serums | 250 units for specified liquid serum | Small and growing UK brands |
| 5. Made By Nature Labs | EU manufacturing advertised | Serums, lotions, cleansing foams and face creams | 500 units stock; 1,000 units custom | Startups and DTC brands |
| 6. Trilogy Laboratories | United States | Vitamin C serums and antioxidant emulsions | 25 units for specified ready formulas | Medspas, professionals and small brands |
| 7. HCP Wellness | India | Vitamin C serums, face mists and custom skincare | Not publicly specified | Indian DTC brands and exporters |
| 8. Hong Shin Cosmetics | Taiwan and South Korea | Serums, ampoules, essences and moisturizers | 1,500 units Taiwan; 3,000 Korea for Vitamin C projects | Growing brands seeking Asian manufacturing |
| 9. Lessonia | France | Powder-to-serum Vitamin C and customized skincare | Not publicly specified | Innovation-led and premium brands |
| 10. Cellular Cosmetics | Australia | Vitamin C creams, toners and custom skincare | 10 units ready formula; custom from 1,000 | Small launches, clinics and growing brands |
The MOQ figures are not directly interchangeable. Some are expressed in finished units, others in bulk volume, and some apply only to selected existing formulations.
Best for: Brands working on a full line of Vitamin C skincare products that need OEM/ODM help.
XIRAN Skincare is a contract manufacturer of skincare products based in China, offering private label products, custom formulation, packaging development and bulk manufacturing.
We have a range of Vitamin C products, a Vitamin C Boosting Face Serum, a Vitamin C Capsules Face Cream and a Vitamin C Daily Facial Sheet Mask. So, for a brand that wants to go beyond the traditional Vitamin C serum, there are a couple of options here.
For example, a capsule cream may have a different texture and product presentation versus a traditional emulsion, while a daily sheet mask may be a complementary product in a brightening-focused regimen.
Our manufacturing services include product concept development, formulation adjustments, packaging coordination, sampling and production. Brands can talk about existing formulas or ask for further customisation depending on technical and commercial requirements.
For standard packaging, we have a standard MOQ of 500~1,000 units per product. Custom packaging, ingredient requirements and specialised product formats may have different minimums.
I would recommend XIRAN to growing DTC brands, skincare companies looking to expand into Vitamin C products, and founders looking to coordinate several product categories with one manufacturing partner.
Before I started formulating, I would decide what type of Vitamin C I wanted, what concentration I was going for, what the texture of the product was going to be like and who I was selling it to. These decisions help determine the appropriate formulation and stability testing strategy.
Best for: Brands looking for American manufacturing, have existing Vitamin C formulas and want scalable bulk production.
RainShadow Labs is a long-standing US-based private label skin care manufacturer that offers stock, semi-custom and fully-custom manufacturing.
RainShadow is relevant to this list because it offers more than just one serum for Vitamin C.
The company’s published catalogue features antioxidant-focused moisturisers such as Super C Crème and Vitamin C Lotion. In its historical product materials, it also refers to Vitamin C serum and other Vitamin C skincare formats.
Those are options to explore for a brand building out a wider antioxidant or brightening collection.
It is important to understand RainShadow’s ordering model. Minimums for private label as published start at 10 gallons for stock formulas and 25 gallons for fully custom formulas. Smaller quantities are also available through the company’s separate sampling and wholesale programs.
These are bulk volume minimums, not fixed amounts of finished product. Number of units will be dependent on the fill size of the product.
For a growing American skincare brand expecting repeat orders or wanting to start out with an existing formula before committing to custom development, RainShadow would be a good option.
One question I’d ask early is about packaging. Brands can offer their own packaging and the company provides vendor referrals, so buyers should verify source of components, filling charges, and approval requirements.
Best for: Established or growing skincare brands looking for custom formulation and manufacturing support.
Salt Lake City, Utah, USA – Nutrix is a US contract manufacturer. It provides services for product development, private label manufacturing, filling, packaging and logistics.
It is relevant to brands looking at more than one Vitamin C product format as its published skincare portfolio specifically includes both Vitamin C Cream and Vitamin C Serum.
I think that is a good way to look at it because a Vitamin C cream formulation is a different process than a water based serum. Emulsion stability, texture, pH and ingredient compatibility all become important parts of the project.
Nutrix offers private label and custom formulations. Its public information also describes support for changing established formulae or developing products from an initial concept.
The skincare page that was reviewed does not list a standard MOQ for Vitamin C. I would therefore ask for separate quotes for an existing serum, an existing cream and a fully customised product, rather than assuming they have the same minimum.
I would consider Nutrix as a manufacturer for a brand with a defined product brief, an established sales channel or a need for ongoing production.
If exclusivity is important, I would clarify formula ownership, development fees, testing responsibilities and whether proposed ingredients require additional stability work before agreeing to manufacturing terms.
Best for: UK startups and independent beauty brands launching a focused range of Vitamin C serums.
Cosmiko is a UK private label skincare manufacturer with existing cosmetic formulations and branding and packaging options.
The company’s line of Vitamin C includes a liquid serum, an oil-based Vitamin C serum and other antioxidant-inspired skincare ideas.
On the company’s website, the Vitamin C Liquid Serum page has 5%, 10%, and 20% strengths of Vitamin C, with a recommended glass dropper bottle of 30 ml. So the minimum published on that particular product is 250 units.
Cosmiko also markets a Vitamin C Oil Serum that uses Ascorbyl Tetraisopalmitate, which is an oil-soluble form of vitamin C. This gives brands yet another route of formulation to explore, rather than just relying on traditional water based Vitamin C systems.
If I was an independent UK beauty brand looking to launch an initial Vitamin C serum without immediately going into a big custom manufacturing program, I would put Cosmiko on my shortlist.
That said, I would check the exact VItamin C ingredient and concentration for each proposed formula. However, a percentage alone does not tell the whole story when comparing the technical properties of different vitamin C derivatives.
The minimum of 250 units should also be considered specific to the published liquid serum and not assumed to apply to all products.
If a brand is planning several SKUs I would ask for a combined quotation for packaging, labelling, samples and minimum for each formula.
Best for: Startups and growing DTC brands who want a wider range of Vitamin C skincare products, and who are open to relatively low starting quantities.
Made By Nature Labs provides private label skincare ready to use and custom formulation services and describes its manufacturing as EU-based.
Published Vitamin C products of the company are: Vitamin C Radiance Serum Vitamin C Brightening & Exfoliating Face Lotion Anti-Age Vitamin C Cleansing Foam
This gives a brand a lot of chances to curate a Vitamin C collection without making every product a leave-on treatment.
I was particularly intrigued by the company’s Vitamin C face lotion which contains 5% 3-O-Ethyl Ascorbic Acid as well as some other ingredients such as Niacinamide and Ferulic Acid. That’s a good example of a manufacturer pinpointing the actual Vitamin C derivative versus a general marketing description.
Made By Nature Labs has a 500-unit MOQ on select existing formulas per product. Its individual custom formulation service starts at approximately 1,000 units per product, depending on the project.
Additionally, the company provides product samples and coordination of labelling and packaging.
If you’re an e-commerce skincare founder launching a small brightening range, I’d take a look at this, especially if your brand is comfortable starting with existing formulations.
The contact details of the company show a Bulgarian company, but the offer shows EU production. I would like to confirm the actual place of production of the offered order.
Best for: Medspas, aestheticians, skincare pros, small brands testing pre-made Vitamin C products.
Florida-based private label skincare manufacturer Trilogy Laboratories offers a portfolio which includes several vitamin C formulations.
Their published offerings include a Vitamin C 20% Serum, a Vitamin C Antioxidant Emulsion and a Vitamin C, B, E & Ferulic Serum.
This list is particularly relevant to the antioxidant emulsion because it is an alternative to a conventional Vitamin C treatment serum. The Vitamin C ingredient in this product is Sodium Ascorbyl Phosphate, the company says. Other ingredients include sodium hyaluronate and ceramide-related ingredients.
Trilogy publishes a 25 unit minimum order quantity per SKU for select ready-made private label formulas. It also says on its product pages that new orders will ship in about 6-8 weeks and repeat orders in 3-5 weeks.
I see Trilogy as a practical choice for skincare professionals who want to trial a branded treatment product, but with a limited initial inventory commitment.
That low MOQ is not to be confused, however, with the minimum for a fully custom formulation.
I would also ask for the current technical specification, INCI list and stability information on the exact formula being quoted. You can't compare active concentrations or make performance claims just by looking at product descriptions.
It might be more important to be able to sample and assess a formula before you scale up than to have a massive product catalogue if you have a small clinic or professional retail program.
Best for: Vitamin C formulation and finished-product manufacturing for Indian DTC skincare brands & exporters.
HCP Wellness is an Indian cosmetic manufacturer that provides private label, OEM, third party manufacturing and custom skincare formulation services.
Its facial serum making abilities include, but are not limited to, Vitamin C serums, and other ingredient-specific serums such as niacinamide and hyaluronic acid serums.
The company also publishes a manufacturing project description for Vitamin C face serum and Vitamin C face mist products for the Indian brand Plush.
This makes HCP relevant to a wider conversation about Vitamin C skincare because it suggests a direction for products beyond a standard dropper serum, although the project details are the company’s own account, not an independently audited case study.
HCP describes services including formulation development, sampling, packaging, filling, labelling and bulk production.
I would consider it for an Indian ecommerce brand that wants to do a Vitamin C serum and then also launch a mist or other skincare products.
That said, the pages I checked don’t show a standard MOQ for these Vitamin C products, so I wouldn’t take a blanket low-MOQ claim for all projects at face value.
I would ask for the available Vitamin C forms, minimum production quantity per formula, packaging options, development fees and relevant export documentation before shortlisting the manufacturer.
Best for: Beauty brands that require Asian manufacturing and want to customise their Vitamin C formulations.
Hong Shin Cosmetics is a Taiwan and South Korea based manufacturer of private label and OEM/ODM skincare products.
Its Vitamin C development page mentions L-Ascorbic Acid and derivatives like Ethyl Ascorbic Acid, Sodium Ascorbyl Phosphate and Ascorbyl Glucoside.
The company names serums as the main form of Vitamin C, and also mentions ampoules, essences and moisturisers as possible development directions.
When a brand is past the point of selecting a product category and is starting to identify specific formulation needs, I’d think of Hong Shin.
Or a brand might want a lightweight Vitamin C essence based on a derivative rather than a low pH L-Ascorbic Acid serum. That decision has implications for texture, packaging, ingredient compatibility, and performance testing.
The MOQ for Hong Shin’s Vitamin C in Taiwan production lines is 1,500 units per SKU, while for Korean production lines it is 3,000 units per SKU with a lead time of 10–12 weeks.
So the place of manufacture should be put in the quotation and supply agreement and not be inferred from the company name.
I would shortlist Hong Shin for a growing brand with a more concrete sales forecast and a specific preference for Asian manufacturing.
Its MOQ is more appropriate for a planned commercial launch than a very small market test.
Best for: Premium skincare lines looking for unusual forms of Vitamin C and unique product concepts.
Lessonia is a French cosmetics company that specialises in private label and customised skin care development.
This is especially interesting for brands that want to go beyond the ubiquitous Vitamin C serums and creams.
On Lessonia’s website, one product concept is a Vitamin C Serum in Powder, which is to be mixed with water to create a single-dose serum just before use.
That method tackles a technical problem worth considering in Vitamin C development: the stability of the active ingredient in the finished formulation.
However, the powder format has its own requirements. I would like to know the consistency with which consumers can reconstitute the product, how the final concentration is controlled, and what instructions are necessary for safe and practical use.
Lessonia has also wider expertise in skincare products, sheet masks, patches, serums and customised cosmetic formulation.
The company website reviewed does not specify a standard MOQ for the Vitamin C powder-to-serum concept.
Lessonia, I would recommend to established or well funded beauty brands looking for a more distinctive product format and the ability to support the associated development and packaging requirements.
I would clarify the full packaging system, single dose quantity, stability data, manufacturing minimum and development timeline before I would ask for a quotation.
Best for: Australian beauty startups, professional skin care businesses and brands testing Vitamin C products before going big.
Cellular Cosmetics is an Australian private label and contract cosmetics manufacturer with a range of existing formulas, OEM/ODM services and custom formulation.
Its published Vitamin C portfolio includes Vitamin C Toner and Clinical Vitamin C Cream.
The toner comes in the form of a light mist and contains ingredients such as Ascorbic Acid, Niacinamide and botanicals. This is a different product format for brands looking for a Vitamin C led moisturising product.
Cellular’s business model has some interesting features – very low entry quantity for existing formulae.
The company advertizes 10-unit minimum orders for its white label products, including its Vitamin C Toner. “This is unlike private label or custom formula projects, which begin at around 1,000 units, but it has more general manufacturing information.
I would research Cellular for a clinic, aesthetician or small Australian skincare company wanting to trial branded products before committing to larger manufacturing.
Small MOQ is nice but doesn’t mean you have exclusive rights to the formulation or unlimited customisation.
For a larger project, I would seek details of formula ownership, what packaging is available, batch testing, repeat order pricing and the exact manufacturing route.
The company’s public document library and product pages are also a place to begin discussing safety and regulatory documentation.
I would use the following shortlist as a starting point, rather than choosing entirely by country.
| Brand Situation | Manufacturers Worth Investigating |
|---|---|
| First-time founder testing small quantities | Trilogy Laboratories, Cellular Cosmetics, Cosmiko |
| Startup seeking existing Vitamin C formulas | Made By Nature Labs, Cosmiko, Trilogy Laboratories |
| Growing DTC brand building a serum-and-cream range | XIRAN Skincare, RainShadow Labs, Nutrix |
| Brand needing a broader Vitamin C skincare collection | XIRAN Skincare, Made By Nature Labs, RainShadow Labs |
| Indian beauty brand or exporter | HCP Wellness |
| Brand seeking Taiwan or South Korea manufacturing | Hong Shin Cosmetics |
| Premium brand investigating an unusual Vitamin C format | Lessonia |
| Professional skincare or clinic retail brand | Trilogy Laboratories, Cellular Cosmetics |
These recommendations are based on published offerings and stated manufacturing models. Final suitability depends on the specific quotation, sample evaluation, and supplier due diligence.
We all know the vitamin C skincare products are everywhere but that doesn’t mean it’s easy to make them well. You can’t just add a known ingredient to a serum or moisturiser.
The form of Vitamin C, the system of formulation, the packaging, the stability, and the intended product claims all influence the finished result.
This is why I would not pick a manufacturing partner on the basis of the lowest MOQ or the biggest product catalogue.
If the first order isn't too large, a new brand can use an existing formula as a sensible way to test demand. A custom formulation and a cohesive skincare collection can provide an established business with more opportunities to stand out.
Either way, I’d start with a solid product brief and a short list of manufacturers with proven capabilities to match it.
At XIRAN Skincare we are experts in private label and custom skincare manufacturing, including Vitamin C serums, creams, masks, and other skincare products.
If you want to develop a Vitamin C skincare line, reach out to our team with your product concept, desired Vitamin C ingredients, target market, packaging needs and estimated order size.
The goal should be to find a manufacturer that can offer the product that your brand truly needs, not just the first factory that can quote you a price.
Published minimums vary substantially. Some ready-made products are offered from 10–25 units, while other programmes begin at 250, 500, 1,000, 1,500, or 3,000 units per SKU. RainShadow Labs uses bulk-volume minimums of 10 gallons for stock formulations and 25 gallons for custom development. These quantities are not equivalent. A low MOQ normally applies to a particular manufacturing route or existing formula. Before ordering, confirm the minimum for your selected product, packaging, fragrance, formula modifications, and fully customized development.
Manufacturing cost depends on the Vitamin C derivative, concentration, product format, packaging, order size, and testing requirements. For an illustrative budget calculation, 1,000 finished products at an assumed $2.50–$6.00 per unit would cost $2,500–$6,000 for those units alone. This is not a verified industry price range or a quotation from the listed manufacturers. Custom formulation, stability and safety testing, packaging development, freight, duties, and marketing may add significantly to the project. Request an itemized quotation before establishing your retail price.
There is no universally best form. L-Ascorbic Acid is well studied but can present stability and formulation challenges. Derivatives such as Sodium Ascorbyl Phosphate, Ascorbyl Glucoside, 3-O-Ethyl Ascorbic Acid, and Ascorbyl Tetraisopalmitate offer different formulation possibilities.
The right choice depends on the intended product type, pH, texture, concentration, packaging, and performance goals. I would ask the manufacturer to explain why it recommends a particular form and provide appropriate stability and efficacy-support information rather than selecting an ingredient solely because it sounds more advanced.
Yes, manufacturers with broader formulation and production capabilities may support Vitamin C serums, creams, moisturizers, toners, cleansers, masks, and other complementary products. However, those formats have different technical requirements and may need separate manufacturing minimums. I would begin by defining the role of each product in the routine.
A serum and moisturizer can be complementary, while adding several nearly identical brightening products may create unnecessary inventory. Ask the manufacturer to quote each formula and packaging format separately before committing to a multi-product launch.
Testing should be based on the actual formula, packaging, intended use, and sales market. I would discuss stability, microbiological quality, preservative effectiveness where applicable, packaging compatibility, and appropriate finished-product safety assessment.
For Vitamin C formulations, active-content and oxidation-related monitoring may also be relevant. Claims about brightening or improving the appearance of uneven skin tone require appropriate support. There is no single universal testing package suitable for every Vitamin C serum, cream, or mask, so the manufacturer should explain the proposed tests and their purpose.
An existing formula can be a practical option for a startup that wants to evaluate the market without paying for extensive development. A custom formula becomes more attractive when the brand needs a specific Vitamin C ingredient, sensory experience, packaging system, or differentiated performance target.
I would begin by sampling suitable existing formulas and comparing them with the product brief. If none meets the requirements, custom development may be justified. Formula ownership, exclusivity, development fees, minimum orders, and testing responsibilities should be agreed before the project begins.
