An Analysis of the Combined Use of Retinoic Acid and Glycolic Acid

Retinoic acid and glycolic acid are both commonly used ingredients in skin care. However, whether the two can be used together needs to be explored in detail.

Retinoic acid has significant effects on skin metabolism, cell differentiation and other aspects. It can promote the renewal of the stratum corneum, improve skin texture, and has good effects on acne, wrinkles and many other skin problems. However, it is also irritating, or causes skin redness, desquamation, sensitivity and other discomfort.

Glycolic acid is a fruit acid, which can loosen the connections between keratinocytes, promote aging keratin shedding, and then brighten skin tone and improve skin texture. It is also commonly used for skin rejuvenation. But it is also irritating to a certain extent, especially at high concentrations.

If the two are used in combination, although there may be synergistic effects, such as in improving acne and skin aging. However, it also greatly increases the risk of skin irritation. Because both have exfoliation, superimposed use may cause excessive exfoliation, damage to the skin barrier, and cause adverse reactions such as redness, tingling, and dryness.

Therefore, if you want to use retinoic acid and glycolic acid in combination, you should carefully evaluate your skin's tolerance. Those with strong skin tolerance may try low-concentration, small-scale trials, and should gradually, from less to more, from low frequency to high frequency. At the beginning of use, pay close attention to the skin's reaction, and stop using immediately if there is any discomfort.

It is wise to consult a professional dermatologist or skin care expert first and get professional advice according to your skin condition. Do not use it rashly, so as not to damage your skin health.
