azelaic acid-a cosmetic material for removing acne

1、 What is azelaic acid

Azoic acid is an organic acid with the chemical formula C9H8O4, commonly used in cosmetics. It is a colorless crystalline solid that is easily soluble in water and ethanol.
This product is a white to slightly yellow monoclinic crystal, needle shaped crystal or powder. Melting point is 106.5 ℃, boiling point>360 (partial decomposition), 226 ℃ (1.33 kPa), 287 ℃ (13.3 kPa), relative density is 1.225 (25/4 ℃), refractive index is 1.4303 (111 ℃). Easy to dissolve in hot water, alcohol, and hot benzene, slightly soluble in water, ether, and benzene.

2、 The role of azelaic acid in skincare products

1. Adjust skin pH value

The ideal pH value for the skin is around 5.5, and when the skin pH value is imbalanced, it can easily lead to skin problems. Adipic acid can regulate the acidity and alkalinity of skincare products, helping to maintain the skin's acid-base balance.

2. Moisturizing effect

Adipic acid can enhance the moisturizing effect of skincare products, making the skin more moisturized. It can maintain skin moisture by forming a moist protective layer.

3. Antibacterial effect

Azoic acid has a certain antibacterial effect and can inhibit some bacteria on the skin, effectively preventing skin infection and irritation.

3、 How to use skincare products containing azelaic acid

Before using skincare products containing azelaic acid, it is necessary to confirm whether your skin is suitable. If the skin is sensitive or has a history of allergies, a skin allergy test should be conducted before use. In addition, when using skincare products, attention should be paid to the ingredient list and skincare products containing other ingredients that may cause allergies should be avoided as much as possible.

4、 Conclusion

Azoic acid is a commonly used ingredient in cosmetics, mainly playing a role in regulating skin pH, moisturizing, and antibacterial effects. However, not all skincare products contain azelaic acid, and attention should be paid to the ingredient list of skincare products before use. If there is skin allergy or sensitivity, a skin allergy test should be conducted first.
