On the Compatibility of Glycolic Acid, Salicylic Acid and Retinol
The compatibility of chemical agents is crucial for skin care
. Glycolic acid, salicylic acid and retinol are all commonly used ingredients in skin care, but whether they can be used together needs to be explored in detail.

Glycolic acid is an alpha-hydroxy acid, which has excellent exfoliation ability. It can loosen the connection between keratinocytes, make old waste keratin shed, promote skin metabolism, make skin smooth and delicate, and increase skin hydration. Salicylic acid, a beta-hydroxy acid, has good lipophilicity, can penetrate deep into pores, remove oil, and dredge pores, which is quite curative for skin problems such as acne. Retinol, a vitamin A derivative, can regulate skin cell differentiation and proliferation, stimulate collagen synthesis, reduce wrinkles, and improve skin elasticity.

However, the use of these three in combination poses a latent risk. Glycolic acid and salicylic acid are both acidic, which can reduce the pH of the skin and cause short-term damage to the skin barrier function, making it relatively sensitive. Retinol itself is also irritating to the skin. If the three are used together, the skin will be stimulated and superimposed, or cause redness, tingling, desquamation and other uncomfortable symptoms. Especially those with sensitive skin are more prone to such conditions.

However, it is not absolutely impossible to use together. If the skin is well tolerated, you can try it step by step. Start with low-concentration products first, and avoid applying them at the same time. You can use them at intervals. For example, use retinol at night, glycolic acid or salicylic acid products in the morning; or use glycolic acid and salicylic acid every other day, diverging from the use time of retinol. At the same time, be sure to do a good job of skin moisturizing and sun protection during use.

If you want to use glycolic acid, salicylic acid and retinol in combination, when carefully assessing your skin condition, try it scientifically. If you feel uncomfortable, stop using it immediately, and consult a professional dermatologist if necessary, so that you can enjoy the benefits of skin care and avoid the harm of skin damage.
