On the Compatibility of Glycolic Acid, Salicylic Acid and Niacinamide
The world's skin care products often want to investigate whether the compatibility of their ingredients is appropriate. Glycolic acid, salicylic acid and niacinamide are all common ingredients in skin care, but whether they can be used in combination is really related to the effectiveness and safety of the skin.

Glycolic acid belongs to the class of fruit acids, which are active and can quickly exfoliate, make the old cells on the surface of the skin fall off, make the skin new and brighten. It can penetrate into the shallow layer of the skin and promote metabolism, so it is very effective in improving skin quality and reducing fine lines.

Salicylic acid, fat-soluble, can penetrate deep into pores, remove oil, clear blockages, and is commonly used in the treatment of acne and acne. And it has anti-inflammatory properties and can relieve skin inflammation and discomfort.

Niacinamide, a derivative of vitamin B3, functions in regulating oil secretion, shrinking pores, increasing skin barrier, and can also block melanin transport and brighten skin.

As for whether the three can be used in combination, it will be analyzed in detail. Glycolic acid and salicylic acid are both acidic, and when used together, they may increase skin irritation. If the skin is sensitive, it may cause redness, tingling, and desquamation. Therefore, for beginners, it is recommended to try it on a small scale first to see if the skin can tolerate it or not. And the concentration should not be high, and it should also avoid skin damage when using it.

Niacinamide is compatible with glycolic acid and salicylic acid, which is theoretically feasible. Niacinamide is relatively stable, and it may change in the extreme acid-base environment. Therefore, when used with glycolic acid and salicylic acid, it is also necessary to pay attention to the order and interval. If niacinamide is used first, after it is absorbed, glycolic acid or salicylic acid can be used, which may reduce adverse reactions.

In general, although glycolic acid, salicylic acid and niacinamide have good effects, it is necessary to be cautious when using them According to your own skin condition, step by step, first test sensitivity, control concentration and frequency, then you can seek the effect of skin care and ensure skin health.
