Discussion on the Compatibility of Azelaic Acid and Glycolic Acid
For the protection of the skin, there are many categories. Azelaic acid and glycolic acid are both commonly used agents for skin care. However, whether the two can be applied together is really related to the effect of skin care and the safety of the skin, which cannot be ignored.

Azelaic acid is mild in nature, has antibacterial and anti-inflammatory properties, and can regulate oil secretion, which is beneficial for acne, pigmentation and other diseases. Glycolic acid is a fruit acid and the like. Its molecules are small and can penetrate deep into the skin, exfoliate, rejuvenate the skin, and make the skin smooth and delicate. It is also often used to improve wrinkles, dullness and other problems.

If the compatibility of the two is discussed, it must be carefully considered Both caps are acidic to a certain extent. When used together, it may cause the skin to be too acidic. The skin has its own balance of acid and alkali. Once it is out of balance, it will be redness and itching in the light, and damage to the skin barrier in the severe. The defense will drop, and it will be easily invaded by foreign objects.

However, if used properly, it must not be used together. If you want to use both, you should first check the tolerance of the skin. Those with strong skin tolerance can try a local trial first. Apply the mixture of the two to a small area of skin, and observe over time. If there is no discomfort, you can gradually expand the scope of use. And the initial dosage should be small. After the skin adapts, you can increase it as appropriate.

Furthermore, the timing of use is also exquisite. Azelaic acid can be used during the day, because it is relatively mild and can resist the damage during the day; glycolic acid can be used at night, and the skin has a strong metabolism at night, and glycolic acid can better exert its skin rejuvenation effect. Such time-sharing use can not only show their respective strengths, but also reduce their combined harm.

In short, although azelaic acid and glycolic acid have their own strengths, when they are used together, they must be cautious. It is necessary to take the suitability of the skin, observe the state of the skin carefully, and apply it reasonably. Only in order to achieve the best condition of skin care and protect the skin's Kangtai.
