On the advantages and disadvantages of using glycolic acid and retinoic acid on the same day
In the way of skin maintenance, both glycolic acid and retinoic acid are commonly used. However, whether the two can be used together on the same day is a matter of concern to everyone.

Glycolic acid belongs to the fruit acid category and has the ability to gently exfoliate. It can make the old keratin on the surface of the skin shed, make the skin look new, and can stimulate collagen production, making the skin firmer and smoother. Retinoic acid has a great impact on the differentiation and proliferation of skin cells, and is often used to improve acne, wrinkles and many other skin problems.

If you want to use glycolic acid and retinoic acid on the same day, the advantages and disadvantages need to be carefully considered.

Let's talk about the benefits first. The mechanisms of action of the two are slightly different. If they are properly combined, they may play a synergistic effect. After exfoliation with glycolic acid, the skin can absorb retinoic acid more smoothly and enhance the effect of retinoic acid to improve skin problems. For example, in acne treatment, glycolic acid clears the keratin blocked at the mouth of the hair follicle, and retinoic acid further regulates the keratinization of the hair follicle sebaceous gland ducts, which may be more effective in reducing acne formation.

However, its disadvantages cannot be underestimated. Both glycolic acid and retinoic acid are irritating to the skin. Use on the same day may cause the skin to be irritated. In light cases, the skin is red, hot, and itchy; in severe cases, discomfort symptoms such as peeling and ting Especially people with sensitive skin are more susceptible to adverse reactions. And excessive use of such irritating products may damage the skin's barrier function, reducing the skin's ability to resist external stimuli, thereby causing more skin problems.

Therefore, if you want to use glycolic acid and retinoic acid on the same day, you must be cautious. Users need to clarify their skin condition first. If the skin is well tolerated, you can try it on a small scale to observe the skin reaction. And when using, you should pay attention to control the dosage and frequency, from less to more, from thin to thick, step by step. If the skin feels uncomfortable during the trial process, you should stop using it immediately and seek professional advice. In this way, we can not only give full play to the advantages of both, but also avoid causing damage to the skin.
