When it comes to the mixed use of glycolic acid and azelaic acid
for skin care, the use of various acids is quite crucial. Glycolic acid and azelaic acid have their own capabilities in the field of skin care. Let's discuss whether the two can be mixed.

Glycolic acid is a type of fruit acid. Its molecules are tiny and can quickly penetrate into the surface of the skin, promote the shedding of stratum corneum cells, accelerate the metabolism of the skin, make the skin glow, and have effects on improving uneven skin tone and fading fine lines.

Azelaic acid can inhibit the growth of microorganisms, has a great effect on skin problems such as acne vulgaris, and can also interfere with the formation of melanosomes, achieving the purpose of whitening light spots.

Whether the two can be mixed needs to be considered in detail. From a chemical point of view, glycolic acid is acidic, and azelaic acid is also an acidic substance. If the two are mixed, if the concentration is not properly controlled, or the skin is too acidic, causing skin discomfort, such as tingling, redness, etc.

However, if used properly, it is also beneficial. For example, for oily skin with acne and dull complexion, it is reasonable to mix the two. Glycolic acid accelerates keratin metabolism, azelaic acid inhibits acne formation, or can synergistically improve skin condition.

But when mixing, be sure to test before small area skin. First take a small amount of the mixture of the two, apply it to the skin behind the ear or the inside of the arm, and observe for 24 to 48 hours. If there is no allergic reaction such as redness, swelling, itching, etc., then use it cautiously on the face. And when initially using, the concentration should be low and the frequency should be less. After the skin adapts, adjust it as appropriate.

In short, when glycolic acid is mixed with azelaic acid, opportunities and challenges coexist. When used properly, it can achieve good skin care effect; if it is slightly careless, it will easily damage the skin. Therefore, skin care providers should be cautious and make reasonable choices according to their own skin characteristics to achieve the purpose of skin care.
