On the suitability of the combination of glycolic acid and retinol
in modern skin care, more research is made on the compatibility of chemical ingredients. Glycolic acid and retinol are often hotly debated. However, whether the two can be used together is really related to the maintenance of the skin, which cannot be ignored.

Glycolic acid belongs to the fruit acid family and is weakly acidic. It is on the surface of the skin, which can loosen the connection between keratinocytes, make the old keratin fall off, and the skin is renewed, the color is also uniform, and it can promote the absorption of subsequent skin care products. Retinol is a derivative of vitamin A, which can stimulate collagen production, improve wrinkles, tighten the skin, regulate keratin metabolism, and is also effective for acne.

The combination of the two may theoretically increase the effect of skin care. Glycolic acid opens the skin channel and helps retinol penetrate better; retinol promotes cell renewal and is associated with the rejuvenation of glycolic acid. However, there are also risks when used together. Both are irritating, and the same use may cause skin intolerance, resulting in redness, swelling, tingling, desquamation, etc. Those with sensitive skin should be especially cautious.

If you want to use glycolic acid and retinol together, you should first test the skin's tolerance. When you start using it, the concentration should be low and the frequency should be less. You can use retinol at night to adapt to the skin, and then add glycolic acid products during the day, but strict sun protection is required. If the skin is uncomfortable after use, it is recommended to stop using it, or consult a professional.

In short, the combination of glycolic acid and retinol, such as good preparation, step by step, or as a way to beautify skin; if used recklessly, it may hurt the skin. Skin care matters should be done with caution to achieve the purpose of skin care.
