On the method of using glycolic acid and azelaic acid together
The disease of the skin is nourished by dori acids. Glycolic acid and azelaic acid are both commonly used products in skin care. However, whether the two can be used together, there are different opinions, let's try it today.

Glycolic acid is an alpha-hydroxy acid and is active. Its molecules are small, can quickly penetrate the stratum corneum of the skin, loosen the binding between keratinocytes, and make the old waste keratin fall off, the skin can be renewed, rejuvenated, and can increase the hydration of the skin, making the skin moist. However, because of its strong activity, first-time users may feel skin tingling and redness.

Azelaic acid, which is friendly to the skin, has antibacterial properties, can inhibit Propionibacterium acne, and can reduce pigmentation, smooth skin papules and pustules, and regulate skin oil secretion. It is suitable for common acne and uneven pigmentation.

The use of both has advantages and disadvantages. The advantage is that glycolic acid promotes keratin renewal, which can help azelaic acid to penetrate better and increase its efficacy. For acne with pigmentation, glycolic acid exfoliates, azelaic acid antibacterial and light spots complement each other. However, there are also risks when used in combination. Both are irritating to a certain extent. When used together, they may cause skin irritation to intensify, such as redness, swelling, itching, and desquamation.

If you want to use both, you should do it with caution. Test the skin's tolerance first and try it on a small area of skin. Start using the appropriate concentration and frequency. For example, choose the concentration of glycolic acid below 5%, and the concentration of azelaic acid below 10%, and use it every few days. After use, observe the skin's reaction. If there is no discomfort, gradually increase the frequency and concentration. And during use, you need to moisturize and protect the skin from sun damage.

In short, the combination of glycolic acid and azelaic acid can be effective if used properly; if not used with caution, it may hurt the skin. Users should carefully observe the skin and act according to their own conditions to achieve the purpose of skin care.
