The theory of azelaic acid 10% and 15%
There is a skin care product in the world, called azelaic acid, which has multiple wonderful effects. However, the concentration is different, and the efficacy and use are also different. Today's discussion of the difference between azelaic acid 10% and 15%.

10% azelaic acid is mild in nature. For those with delicate skin, it is appropriate to choose this concentration for skin care products for the first time. It can be relieved in ordinary skin discomfort, such as micro-inflammation and the beginning of acne. It can inhibit skin oil, regulate its secretion, and slightly control keratinogenesis, making the skin's surface fine. However, its strength is slightly slower, if the skin is sick and severe, it may be difficult to see great results quickly.

As for azelaic acid 15%, the strength is even stronger. It is suitable for those with good skin tolerance, and those with slightly heavier acne and more obvious inflammation. It can strongly inhibit Propionibacterium acne, which is one of the main causes of acne, so it can reduce acne and grow hair. Its antioxidant ability is also strong, which can slow down the oxidation of the skin, lighten the printing and remove the sinking, and make the skin tone even and bright. However, because of its strong strength, it may cause slight prickles and dry itching to the skin when used for the first time, so it is necessary to test sensitivity before use and use it gradually.

Compared with the two, 10% are humble and gentle, suitable for those who are initially involved in skin care and sensitive skin; 15% are like a fierce general, overcoming difficulties, and are more effective for more serious skin problems. However, skin tolerance is required. Users should choose carefully according to their skin characteristics in order to get the beauty of skin care and radiant skin.
