"On the Effect of Retinol and Glycolic Acid"

The way of skin maintenance, the effect of retinol and glycolic acid is often the focus of public debate. Retinol is derived from the life-sustaining element A, which has many wonderful uses. It can promote the renewal of skin cells, make old keratin gradually remove, make the skin new, uniform in color, and gradually eliminate fine lines. And it can stimulate the production of collagen, making the skin firm and elastic, just like the wood of spring, gradually regaining vitality.

Glycolic acid belongs to the family of fruit acids. Its molecules are tiny and can travel smoothly through the shallow layers of the skin. It can loosen the adhesion between keratinocytes, causing the stratum corneum to fall off, and the skin feels smooth and delicate, just like an egg at the beginning of peeling, and the skin is like condensation. It can also increase the hydration ability of the skin, making the skin moist and radiant.

However, compared with the two, each has its own short and long. Although retinol has the effect, when it is first used, some people with sensitive skin may feel uncomfortable, such as redness, tingling, etc. It must be started from a low concentration, and the dosage should be gradually increased to make the skin adapt slowly. Although glycolic acid is relatively mild, high concentrations may also cause skin irritation. If used improperly, it may damage the skin's barrier and weaken the skin's resistance.

Therefore, those who desire good skin care should carefully observe the nature of their own skin. For dry and sensitive skin, it may be advisable to try low-concentration retinol first, gradually; for oily and well-tolerated skin, glycolic acid may be a good choice, but it also needs to be adjusted in a timely manner according to the skin's reaction. Only by using it cautiously can we do our best to obtain the best state of the skin and the radiance of youth.
