At the turn of spring and summer, the temperature gradually rises, and the amount of skin oil secretion increases significantly! This season is a big problem for the oil skin, so how to improve the problem brought by the oil skin! Without introducing products, we can also talk about a common ingredient in skin care products this season!
What is it? Is the skin care into the boundary of the generalist - azelaic acid!
Azelaic acid, also known as azelaic acid.
Although it is called azalea acid, it has nothing to do with azalea!
I have reason to believe that it was definitely the translation of God that gave birth to "Azelaic acid"!
Azelaic acid is a naturally occurring saturated straight chain dicarboxylic acid.
Don't think that it is simple, just think that it has a small role in skin care products! Let's talk about what it does.
Oil control
It was found that 5α-reductase is a key enzyme in skin androgen metabolism, and androgen can stimulate sebaceous glands to secrete oil, and azelaic acid can effectively inhibit 5α-reductase, thereby improving oil secretion.
Whitening effect
Studies have found that 20% azelaic acid is more effective than 4% hydroquinone in improving mild melasma, although the article mentions that further clinical trials are needed to support this conclusion!
Anti-inflammatory effect
It was found that peroxisome proliferator-activated receptor γ (PPARγ) plays a key role in controlling inflammation and is easily activated by fatty acids and lipid peroxidation products. Azelaxic acid can effectively inhibit the rise of inflammatory factors induced by UVB.
In addition to these effects, azelaic acid can effectively inhibit propionibacterium acnes, and can effectively improve acne vulgaris and rosacea.
So azelaic acid has no disadvantages?
Of course there is!
Those who are familiar with it know that azelaic acid is poorly soluble in water and can dissolve in ethoxy diglycol.
Azelaic acid can be modified (azelaic acid potassium glycine) or wrapped in azelaic acid two common treatment methods to improve its application limitations.
In summary, azelaic acid is a versatile skin care product, but azelaic acid does have some shortcomings, poor solubility in water, can dissolve in ethoxydiethylene glycol, direct use has certain limitations, azelaic acid can be modified by azelaic acid (azelaic acid potassium glycine) or wrapped azelaic acid two ways to improve its limitations.
