On the method of using glycolic acid and retinol at night
Recently, the method of skin care involves more ingredients and uses them. Glycolic acid and retinol have attracted much attention in the night skin care. However, the use of both needs to be considered in detail.

Glycolic acid, a fruit acid and the like, has the ability to gently exfoliate, which can smooth the metabolism of the skin, rejuvenate the epidermis, and make the skin smooth and shiny. Retinol, a derivative of vitamin A, can help collagen regenerate, reduce fine lines, and improve skin texture, with outstanding effect.

If you want to apply glycolic acid and retinol at night, you should know the tolerance of the skin. At the beginning, it is advisable to try it locally. Take a small amount of glycolic acid products, apply it to the skin behind the ear or under the chin, and wait for 24 hours to see if it has redness and itching. If there is no discomfort, you can gradually apply it to the face.

As for the application sequence, the common method is to apply glycolic acid first. After it is completely accepted by the skin, about a quarter of an hour, then apply retinol. This move aims to use glycolic acid to dredge pores and exfoliate, so that retinol can more easily penetrate the skin and exert its effect. However, it should be noted that both glycolic acid and retinol are irritating to a certain extent. When used together, it may increase skin discomfort. Therefore, the frequency of application should be slowed down. At the beginning, once to twice a week can be used. When the skin adapts, the number of times should be increased.

When applying both, daytime protection should not be ignored. Both can increase the skin's sensitivity to light. During the day, sunscreen products should be strictly selected and avoided under strong light to prevent sunburn and anti-tanning of the skin.

After all, glycolic acid and retinol are used together at night. If used properly, it can add color to the care of the skin; if used carelessly, it may damage the skin. Be careful, according to the nature of the skin, and do it reasonably, in order to achieve the best state of skin care.
