When it comes to the combination of glycolic acid and azelaic acid,
the beauty of the skin is expected by everyone, and the way of skin care is becoming more and more detailed. Glycolic acid and azelaic acid are both commonly used ingredients in skin care, but whether they can be used together is quite confusing.

Glycolic acid is an alpha-hydroxy acid, whose molecules are tiny, which can quickly penetrate the surface of the skin and promote the renewal of stratum corneum cells. It removes old and waste keratin from the surface of the skin, restores the skin's luster, stimulates collagen production, improves fine lines and roughness, and makes the skin firm and smooth.

Azelaic acid has antibacterial properties, especially significant inhibition of Propionibacterium acne, can reduce sebum secretion, improve abnormal hair follicle keratosis, and is beneficial to acne and acne. And it can block the transport of melanosomes, lighten skin spots, and even skin tone.

As for whether the two can be used together, it needs to be considered in detail. Glycolic acid can increase skin permeability, but it also makes skin sensitivity slightly increased. Azelaic acid is relatively mild, but the use of both may cause skin irritation. If the skin is tolerant, try it on a small scale without discomfort, and use it cautiously to obtain multiple skin care effects. Use glycolic acid first, wait for the skin to adapt for a while, then use azelaic acid, and the dosage should be small and gradually increase.

However, those with sensitive skin must not use both rashly. Use a single ingredient first to observe the skin's reaction. If it is well tolerated, then try to use both as appropriate. Or consult a professional to obtain accurate methods according to your own skin type.

In short, the combination of glycolic acid and azelaic acid has advantages and disadvantages. When taking care of your skin, you must take your own skin type as the basis and act cautiously to protect the health of your skin and achieve the purpose of beauty.
