As temperatures rise and UV intensity increases, sun protection has become an important part of summer skincare. However, many people's understanding of sunscreen is still to the extent of preventing tanning and sunburn, but in fact, sunscreen is much more than that.
What we need to understand is what sun protection is. To put it simply, sun protection is to reduce damage to the skin by applying sunscreen products to block or absorb ultraviolet rays from the sun's rays. However, different wavelengths of ultraviolet light have different effects on the human body. Among them, UVA can penetrate the clouds to reach the ground, and long-term exposure to the sun will lead to skin aging, wrinkles and even pigmentation, while UVB is the main cause of solar dermatitis, and high-dose radiation in a short period of time will cause symptoms such as redness, swelling and pain.
Therefore, it is very important to choose the right sunscreen product. Generally speaking, the higher the SPF value, the stronger the protection, it is recommended to use a sunscreen with an SPF of 30 or higher when outdoors, and reapply every two hours. At the same time, waterproof sunscreens are better resistant to the effects of liquids such as sweat and seawater. In addition, physical sunscreens (such as zinc oxide and titanium dioxide) may cause allergic reactions in some people, although they are not absorbed by the skin, so if you try it for the first time, you can choose a chemical sunscreen product.
In addition to external protection, internal conditioning should not be neglected. Adequate hydration can help keep your skin moisturized and avoid dehydration that makes your skin more susceptible to UV rays. It is also important to eat right. Foods rich in vitamin C help fight free radical damage and help repair damage, while foods containing antioxidants can further strengthen the skin's defenses.
Sun protection isn't just for skin, it's for health. I hope everyone can develop good sun protection Xi and make their skin more radiant!
