As the weather gets hotter and hotter, the sun is also more and more brilliant, and with it, outdoor activities are also more frequent. To resist the sun's rays, hats, umbrellas, sunglasses, gloves, and other sun protection supplies gradually come in handy, Many people’s understanding of sun protection is still limited to preventing tanning and sunburn. Sun protection is much more than that.
n addition to these common sunscreen supplies, before going out to apply sunscreen has also become a necessary process. Sunscreen refers to cosmetics that add sunscreen agents that can block or absorb ultraviolet rays to prevent the skin from tanning and sunburn. So did you know that the sunscreen we use is also divided into physical sunscreen and chemical sunscreen, what is the difference between them? Here's what we know.
Chemical sunscreens and physical sunscreens protect your skin from the sun's UV rays in different ways.
Physical sunscreens: The principle is to use sunscreen particles to form a protective layer on the surface of the skin to reflect ultraviolet rays to protect the skin. The main ingredients are titanium dioxide and zinc oxide, which use physical coverage to block, reflect or scatter UV rays so that the amount of UV rays reaching the skin is reduced for sun protection purposes. Physical sunscreen generally only stays on the surface and will not be absorbed by the human body, so it will not cause any harm to the human body and is more suitable for people with sensitive skin.

Physical sunscreens are less irritating to the skin, more suitable for people with sensitive skin, and relatively safer.Chemical sunscreens are generally more refreshing, have a good skin feel, are not whitish, and are not greasy.The first thing you need to do is to pick a sunscreen that is safe for your skin and not allergic, and then consider sun protection parameters such as SPF index and PA index afterwards.
In addition, a reasonable diet is also very important. Foods rich in vitamin C help resist free radical damage and help the skin repair damage; foods containing antioxidants can further enhance skin resistance. Sun protection is not only for beautiful skin, but also for health. I hope everyone can develop good sun protection habits and make their skin more radiant!
