The combination of azelaic acid and glycolic acid has attracted much attention recently. However, the combination of the two needs to be considered in detail.

Azelaic acid has antibacterial and anti-inflammatory properties and can improve many skin defects, such as acne vulgaris and pigmentation. Its effect is mild, it can inhibit the growth of abnormal flora on the skin surface, and it is also effective in regulating keratin metabolism, restoring the normal metabolic rhythm of the stratum corneum of the skin, thereby making the skin texture more delicate.

Glycolic acid, a fruit acid or the like, has very small molecules, which can quickly penetrate into the surface of the skin, loosen the adhesion between keratinocytes, promote the shedding of old keratin, and accelerate the metabolism of the skin. Often used, it can make the skin glow, reduce wrinkles, and is also quite effective in improving uneven skin tone.

However, if you use both, you must be cautious. Glycolic acid thins the stratum corneum of the skin, and the skin sensitivity may be improved. At this time, if you use azelaic acid together, it may strengthen the effect of skin care, but it also increases the risk of skin discomfort. Such as redness, tingling, dryness, etc. If you want to use both, you should first check the tolerance of the skin.

At first, you can try glycolic acid alone. From a low concentration, such as 2% - 5% of the product, once to twice a week, until the skin adapts, there is no adverse reaction, and then gradually increase the frequency of use. Then, you can add azelaic acid as appropriate, and use it at a low concentration and less frequency at the beginning. If it is first in the evening, use the product with a 10% concentration of azelaic acid the next day, staggered with the use time of the glycolic acid product.

If the skin is unwell during use, stop using it immediately, and wash it off with water, depending on the severity of symptoms, or seek medical treatment, or temporarily stop the skin care steps. When the skin returns to normal, try again, and appropriately reduce the frequency and concentration of use.

In conclusion, the combination of azelaic acid and glycolic acid may achieve better skin care results. However, it is necessary to follow the skin characteristics, use it step by step, and use it cautiously to ensure skin health and achieve the desired effect.
