When it comes to the compatibility of glycolic acid serum and retinol
, both glycolic acid serum and retinol are commonly used for skin care. However, whether the two can be used together, there are different opinions, and it needs to be studied in detail.

glycolic acid serum has the power of rejuvenation. It can loosen the connection between keratinocytes, shed old and waste keratin, renew the skin surface, glow with natural luster, and promote the skin's absorption of subsequent skin care products. Guanfu retinol, a derivative of vitamin A, has a great impact on skin metabolism, can stimulate collagen production, improve skin texture, reduce wrinkles, and is a good anti-aging agent.

However, the use of both is also risky. Glycolic acid serum is acidic, which can cause the pH value of the surface of the skin to drop, making the skin relatively sensitive. Retinol itself is also highly irritating to the skin. If the two are used together, it may cause skin irritation to intensify, redness, tingling, desquamation and other diseases.

If you want to use both, you should be cautious. Those with strong skin tolerance can try a small amount first to observe the skin's reaction. For example, use glycolic acid serum and retinol at intervals of several days before local skin. If the skin is no different, try to shorten the interval. And those with sensitive skin must not use both rashly. They should first use gentle methods to maintain the skin and improve the skin's tolerance before they can consider it again.

In short, the compatibility of glycolic acid serum and retinol needs to be weighed according to personal skin conditions, and the pros and cons should be carefully selected to achieve the purpose of maintaining the skin without damaging the skin.
