On the advantages and disadvantages of the combination of glycolic acid and retinol

The use of glycolic acid and retinol is quite popular. The combination of the two has advantages and disadvantages, let me tell you one by one.

Glycolic acid is a type of fruit acid and has excellent exfoliation effect. It can gently exfoliate the aging exfoliation on the surface of the skin, making the skin look delicate and smooth. And it can accelerate the metabolism of the skin, promote the production of collagen, thereby improving the texture of the skin, fading fine lines and pigmentation.

Retinol is a derivative of vitamin A. It has significant effects on skin cell renewal, collagen synthesis and reducing oil secretion. It can effectively fight skin aging, improve skin firmness, improve acne, acne and other problems.

The combination of the two has three advantages. First, synergistic effect. After exfoliation by glycolic acid, retinol is more easily penetrated into the deep layers of the skin and exerts its ability to promote cell renewal. The two complement each other, and the effect of fighting aging and improving skin texture is more outstanding. Second, broaden the scope of application. For people who have both aging problems and acne troubles, the combination can not only improve fine lines, but also regulate oil secretion and solve multiple skin problems. Third, save skin care time and energy. When the two are used in combination, there is no need to use multiple products to deal with different skin conditions.

However, the combination also has disadvantages. First, the irritation is enhanced. Glycolic acid and retinol are both irritating in themselves. After combined use, the challenge to skin tolerance increases. Those with sensitive skin are prone to redness, tingling, peeling and other uncomfortable symptoms. Second, the risk is increased. If used improperly, such as excessive dosage and excessive frequency, it may cause excessive dryness and damage to the skin, damage the skin barrier, and then cause more skin problems.

Therefore, those who want to combine glycolic acid and retinol should be cautious. Test skin tolerance first, starting from low concentration and low frequency, and gradually increase the dosage and frequency. If the skin is uncomfortable, stop using it immediately and consult a professional for advice. In this way, the benefits of the combination of the two can be obtained, avoiding its drawbacks and protecting the health of the skin.
