On the compatibility of retinol and glycolic acid
In the way of skin maintenance, retinol and glycolic acid are both commonly used agents. However, whether the two can be used together is really related to the maintenance effect and the safety of the skin, which cannot be ignored.

Retinol is derived from vitamin A, which is very useful in skin metabolism, cell renewal and collagen production. It is often used to improve wrinkles, roughness, and make the skin firm and smooth. Glycolic acid is a type of fruit acid, which can loosen the connection between keratinocytes, promote exfoliation, make the skin glow, and also help improve pigmentation, acne and other diseases.

The two are used alone, and each has its own strengths. When using them together, it needs to be carefully considered. Retinol has a certain irritation, which can cause redness, dryness and desquamation of the skin. Glycolic acid can also increase the permeability of the skin and make the skin more sensitive to irritation. If the two are used in combination, or the irritation is superimposed, the skin will not be able to be disturbed.

However, if used properly, there is also a wonderful synergy. When using it for the first time, it is recommended to try it on a small scale to see if the skin is uncomfortable. The initial concentration should be low, and then gradually increase when the skin adapts. And use it for the time, or use glycolic acid during the day and retinol at night to avoid it acting on the skin at the same time.

In short, the compatibility of retinol and glycolic acid has advantages and disadvantages. Users should carefully observe their own skin condition, weigh the pros and cons, and use it cautiously to achieve the best condition of skin care and avoid the risk of skin damage.
