"Skin Care"

The nourishment of the skin is related to the face. Today there are two things, one is retinoic acid and the other is glycolic acid, which are effective in skin care.

Retinoic acid can start the process of skin renewal. Helps exfoliate in an orderly manner and promotes cell renewal and regeneration. The skin is like returning to the earth in spring and glowing with vitality. It can make the rough ones gradually smooth, the dull ones slightly shine, and the fine lines and shallow marks can also be improved.

Glycolic acid is a genus of weak acids and has the power of gentle exfoliation. It can loosen the adhesion between the stratum corneum and make the stratum corneum light and even. If used, the skin will be cleansed and transparent. And it can improve the hydration of the skin, making the skin as smooth as coagulation.

However, although both are wonderful, it is necessary to use them with caution. Test the sensitivity first and check the tolerance of the skin. The starting dosage should be small and the frequency should be sparse. After the skin adapts, it can be gradually improved. If used, the skin may be damaged, causing redness, swelling and tingling.

Therefore, those who want to beautify their skin should make good use of retinoic acid and glycolic acid according to the nature of the skin. With scientific methods and perseverance, they will be able to obtain the best state of the skin and radiance.
