When discussing whether Differin and Glycolic Acid can be used at the same time, it is necessary to understand the characteristics of both. Differin, whose active ingredient is usually adapalene, is often used in the treatment of acne vulgaris. It plays a role in regulating the keratinization of the hair follicle mouth, improving the keratinization of the hair follicle sebaceous gland duct, dissolving microacne and acne, and anti-inflammatory. Glycolic acid is an alpha-hydroxy acid. With its small molecule, it is easy to penetrate the skin, can remove the accumulation of keratin on the skin surface, promote skin metabolism, and make the skin smoother and more delicate. It is often used to improve skin texture, fade pigmentation spots, and improve pigmentation and acne marks after acne.

Using both at the same time, risks coexist. On the one hand, both are irritating to the skin. When used in combination, it may significantly enhance the skin irritation response, causing redness, itching, tingling, peeling and other discomforts in the skin. For those with sensitive skin, this adverse reaction may be more serious. On the other hand, excessive exfoliation will destroy the skin barrier function, reduce the skin's ability to resist external stimuli, and make it more susceptible to pathogens such as bacteria and viruses, causing infection, and the skin moisture loss will accelerate and become dry.

If you insist on using it at the same time, be careful. First, try it on a small area of skin, such as behind the ear or in the jaw, and observe it for 24-48 hours. If there is no adverse reaction, you can gradually expand the scope of use. Secondly, in the initial stage, reduce the frequency of use, such as 1-2 times a week, and then increase it moderately after the skin adapts, but not too frequently. Furthermore, do a good job of moisturizing the skin, use gentle moisturizing skin care products, and maintain skin moisture. During use, if the skin experiences serious discomfort, it should be stopped immediately, and a professional dermatologist should be consulted for advice.

In short, although the use of divir and glycolic acid at the same time may bring certain skin improvement effects, the risk should not be underestimated. Users must fully understand their skin condition, weigh the pros and cons, and take scientific and cautious skin care to protect skin health.
