On the advantages and disadvantages of glycolic acid and vitamin C

Recently, there has been a lot of discussion on the efficacy of glycolic acid and vitamin C. In various forums, this topic has been hotly discussed, especially on Reddit.

Glycolic acid belongs to the class of fruit acids and has unique chemical properties. Its molecules are small, so it can easily penetrate the surface of the skin and reach the depths of the stratum corneum. With this property, glycolic acid can loosen the connection between keratinocytes, promote the shedding of old waste keratin, and then achieve the effect of skin rejuvenation. After long-term use, the skin can be seen to be delicate and smooth, and the color is gradually uniform, which is quite significant for the improvement of dull and rough skin.

However, vitamin C is not idle. It is a natural antioxidant and has outstanding achievements in the antioxidant level of the skin. It can effectively neutralize free radicals and inhibit their damage to skin cells, thereby delaying skin aging. Vitamin C can also participate in the synthesis of collagen, making the skin more elastic and firm. Moreover, it is also effective in whitening the skin, inhibiting the production of melanin, fading pigmentation, and brightening the complexion.

Compared with the two, glycolic acid focuses on the conditioning of the stratum corneum of the skin, improving the texture of the skin immediately; while vitamin C focuses on antioxidant and whitening, and the effect is more long-term and comprehensive. When using glycolic acid, it is necessary to pay attention to its irritation. The initial use should start from a small dose and a low frequency, so that the skin can gradually adapt, otherwise it may cause skin redness, swelling, tingling and other discomfort. Although vitamin C is relatively mild, some people may also have allergic reactions to it, and its stability is not good, so it needs to be properly stored.

In general, glycolic acid and vitamin C have their own advantages. When choosing to use it, it should be carefully chosen according to personal skin characteristics, needs and tolerance conditions, so as to achieve the best skin care effect.
