On the importance of glycolic acid and sunscreen
glycolic acid is widely used in the skin. It has unique properties, can rejuvenate the skin, and make the epidermis renewed and orderly. However, its use also needs to be careful, and it is closely related to sunscreen.
Glycolic acid can loosen the connection between keratinocytes, help old keratin to fall off, make the skin more tender and smooth, and may promote the production of collagen in the dermis and increase skin elasticity. However, after using glycolic acid, the skin's sensitivity to ultraviolet rays often increases. Because during the process of stratum corneum renewal, new skin is delicate, and it is more vulnerable to damage if exposed to ultraviolet rays.
Therefore, when using glycolic acid, sun protection is indispensable. The first method of sun protection is physical shielding, such as wide-brimmed hats and parasols, to block ultraviolet rays from directly shining on the skin. In addition, choose suitable sunscreen products. It needs to be selected according to the skin type. Dry skin should be moisturized, and oily skin should be refreshing and not oily. And the sun protection index also needs to be appropriate. A lower index can be selected indoors every day. When going out for a long time or strong sunshine, a high index should be used.
Using glycolic acid is also good for sun protection. The two can cooperate to ensure healthy skin, rejuvenate the skin, and avoid the harm of ultraviolet rays.
