In Chengdu light spot industry for many years, many beauty ladies like to use all kinds of whitening ingredients or eat a variety of whitening pills, in fact, most people do it wrong, in fact, want to do light spots, the first step should be this!
As we all know, ultraviolet radiation will darken the skin, because ultraviolet rays will stimulate the production of skin melanin, want to whiten sun protection is essential, and ultraviolet rays are also the culprit of photoaging, long-term ultraviolet radiation skin wrinkles increase. In addition, there are also studies that ultraviolet rays can stimulate facial inflammation, aggravate skin allergies and acne inflammation ~ So I insisted on applying sunscreen for half a year, rarely have inflammatory acne, and the skin as a whole is much healthier than before!! In addition, there is a question here, some sister paper think that the sunscreen itself has irritation, this is not denying, chemical sunscreen does harm the skin, but! Compared with the effects of ultraviolet rays on the skin, sunscreen as a whole has more benefits than harms!
Sun protection is not as simple as preventing the skin from darkening, but by reducing the damage caused by ultraviolet rays to the skin, so that the skin remains in a healthy state. With many years of experience in Chengdu light spots, I will give you a popular science of the theoretical knowledge - ultraviolet light It is divided into UVB and UVA two, UVB can make the skin sunburn in a short time, red, SPF on sunscreen is a sign of UVB protection ability. UVA is very penetrating, can pass through glass, clothing, straight to the dermis layer of the skin, deep into the tissue below the dermis, destroy elastic fibers and collagen fibers, although in cloudy days can also penetrate thick clouds to harm our skin. So, apply sunscreen every day!
Benefits of using sunscreen every day
1. Ultraviolet rays will produce melanin, if it is irradiated by ultraviolet rays for a long time, it is very easy to cause darkening, but also harm skin health, serious will also lead to skin cancer, so if you want to have fair and healthy skin to avoid ultraviolet rays, even if it is rainy, ultraviolet rays still exist, if you do not pay attention for a long time, it is easy to be damaged by ultraviolet rays. There are many ways to avoid ultraviolet rays, such as umbrellas, sun hats, sunglasses, and the use of sunscreen products that suit you, if you insist on using sunscreen, you can save a lot of whitening skin care products.
2. Ultraviolet rays are a high-energy ray, long-term exposure to ultraviolet rays can easily lead to poor skin elasticity, and will also produce wrinkles, thereby accelerating the aging of the skin, if you want to delay aging, reduce fine lines, wrinkles must do a good job of sun protection, to avoid skin damage.
These concepts you need to know about sunscreen – physical sun protection & chemical sun protection
Sun protection principle: physical sunscreen (containing titanium dioxide, zinc oxide): form a protective film on the skin, so that ultraviolet rays cannot penetrate the skin surface; Chemical sunscreen: absorbs ultraviolet rays, converting it into other energy;
Advantages and disadvantages: physical sunscreen: effective immediately after application, less irritation to the skin, and a little unnatural touching; Chemical sunscreen: relatively refreshing, non-sticky, has a certain irritation to the skin.
SPF & PASPF: Protection against UVB, the main function is to protect against sunburn, such as SPF30, which allows the skin to appear reddened after 30 minutes, but without application, it can be reddened in 1 minute in the sun. PA: For UVA, the main function is to protect against tanning, the more + signs, the stronger the ability to resist UVA (usually 1 + number can delay the skin tanning time by 2-4 times).
With many years of experience in Chengdu light spots, I seriously advise all beauty lovers to pay attention to sun protection!
