Tretinoin and Glycolic Acid Combined Use
Whether retinoic acid and glycolic acid can be used in combination is a topic of concern in the field of skin care. Today we discuss the combination of retinoic acid and glycolic acid in detail.

Retinoic acid has significant effects on skin cell metabolism and stratum corneum renewal, and is often the choice for improving acne and anti-wrinkle. Glycolic acid is a fruit acid, which can loosen the connections between keratinocytes, promote stratum corneum shedding, and can also brighten skin tone and improve skin texture.

The combination of the two may theoretically have synergistic effect. Retinoic acid promotes cell renewal, glycolic acid exfoliates, or more effectively improves skin problems. However, it should be noted that both are irritating. Retinoic acid can cause skin dryness, desquamation, and redness; glycolic acid can also increase skin sensitivity to irritation. In combination, the risk of skin irritation increases greatly, or severe dryness, tingling, burning, and even contact dermatitis.

Therefore, the combination of retinoic acid and glycolic acid should be used with caution. Try it before a small piece of skin to see if there is any discomfort. Initial use, the frequency should be low, such as once a week, and then gradually increase according to skin tolerance. If the skin is uncomfortable during use, it should be discontinued immediately, and if necessary, seek treatment from a dermatologist.

In short, the combination of retinoic acid and glycolic acid may bring skin care benefits, but the irritation cannot be ignored. Users must be cautious and choose reasonably according to their own skin type to achieve the purpose of skin care and skin health.
