In previous videos and articles, we have introduced the time and frequency of sunscreen application. There are a variety of sunscreens on the market today, with a variety of ingredients and a variety of functions. Some of them can help us strengthen our skin's ability to defend against light exposure.
This is the antioxidant.
How can antioxidants help protect the skin?
Antioxidants are a general term for a class of skin care ingredients, it can protect the skin before the occurrence of photodamage, resist the effects of damage, photoaging brought about by some fine lines, pigmentation, uneven skin tone and other phenomena, can be through the neutralization of antioxidants and free radicals to protect the skin from light and unstable compounds caused by damage to the skin.
Simply put, all antioxidants help lower the level of free radicals by neutralizing free radical compounds, and antioxidants can provide an electron to a certain type of free radical at the molecular level to stabilize the function of these free radicals, thereby achieving the effect of protecting the skin.
This helps prevent further oxidation reactions, which break down collagen and prevent the skin tissue from repairing itself.
The antioxidants in sunscreens therefore help combat the pigmentation caused by photoaging, create a more even complexion, and prevent the breakdown of collagen by oxidative stress.
However, not all antioxidants have the same effect on sun protection, and some antioxidants are more powerful in preventing UV damage. If you need to go outdoors during the scorching summer, choose these sunscreen antioxidant serums with broad-spectrum sunscreens.

Scientists have proven that resveratrol has a certain chemopreventive effect, which can prevent skin cells from being damaged by ultraviolet radiation, and like most antioxidants, it can not only help resist ultraviolet rays, but also protect the skin from the effects of free radicals on collagen synthesis.
