On the combination of azelaic acid and salicylic acid
The disease of the skin depends on various medications to treat it. Azelaic acid and salicylic acid are both commonly used ingredients in skin care, but whether the two can be mixed and used is often doubtful.

Azelaic acid is mild in nature, has antibacterial properties, can inhibit the growth of Propionibacterium acne, and can regulate keratin metabolism, making the skin texture even. For inflammatory acne, it has significant effect, can reduce redness, eliminate pustules, and restore the smoothness of the skin. And because it can hinder the activity of tyrosinase, it is also beneficial for the desalination of pigmentation.

Salicylic acid is a fat-soluble organic acid. It is good at penetrating deep into pores, removing oil, and dissolving corneal suppositories. It is quite effective for the removal of acne and blackheads. And it has anti-inflammatory properties, can relieve skin inflammation, reduce redness, swelling and pain.

As for whether the two can be mixed, it needs to be considered in detail. Both have a certain exfoliation effect. If used in combination, this effect may be superimposed. When initially used, the skin may feel slightly tingling and redness, which is a sign of skin adaptation. If the skin tolerance is strong, gradually increase the dosage and frequency from a low concentration, or it can be tolerated. However, those with sensitive skin need to be careful. Due to its superimposed peeling, or damage to the skin barrier, the skin loses its ability to resist external stimuli, causing moisture loss and making it more prone to allergies.

Therefore, if you want to mix azelaic acid and salicylic acid, you should try it on a small piece of skin first and observe its reaction. If there is no abnormality, you can gradually expand the use area. And when using, you need to pay attention to the moisturizing and sun protection of the skin to protect the health of the skin. In this way, you can achieve the best effect of skin care and avoid the risk of skin damage.
