On the combination of retinol and glycolic acid
for the nourishment of the skin, there are many categories. Retinol and glycolic acid are both good materials for skin care. However, whether the two can be used together is quite a concern for everyone.

Retinol is an alcohol. It is good for the skin. It can promote the replacement of cells and increase the production of collagen, so it can reduce wrinkles and strokes, making the skin firm and elastic. And it can help the metabolism of keratin, making the skin surface smooth and delicate.

Glycolic acid is a kind of fruit acid, with tiny molecules that can quickly penetrate the surface of the skin. It well dissolves the adhesive between the cuticles, removes old and waste cuticles, refreshes the skin, and can also increase the moisture content of the skin, making the skin moist.

However, both are irritating. If used together rashly, it may cause skin intolerance, redness, swelling, tingling, and desquamation. Cover retinol can make the skin more sensitive to stimulation, and glycolic acid can exfoliate the cuticles. The two are superimposed and stimulated.

If you want to combine retinol and glycolic acid, you should use them step by step. At the beginning, it is recommended to use one alone first, and then try the two together when the skin adapts. And the starting concentration should be low, and the frequency of use should be sparse. If you use low-concentration retinol first, use it every day. After a few weeks, if there is no discomfort to the skin, then increase the frequency. Then, you can use low-concentration glycolic acid at different times.

When using it, you should also pay attention to the skin's reaction. If you feel uncomfortable, you should stop it immediately and wait for the skin to calm down before trying again. And when using these two during the day, you need to take strict sun protection, because it may increase the skin's sensitivity to light.

In short, if retinol and glycolic acid are used appropriately, they can add color to the skin; if they are not used carelessly, they will hurt the skin. Therefore, users should be cautious and use scientific methods to seek the best state of the skin.
