Adapalene is a kind of white to gray -white powder, soluble in tetrahydrocarbu, slightly soluble in ethanol, almost insoluble in water. Molecular formula is C28H28O3 molecular weight is 412.52. adapalene's structure is as follows:

Ren Er acid ( AZA) is an organic compound with a molecular formula HOOC (CH2) 7COOH. This saturated di carboxylic acid exists in the form of white powder. It exists in wheat, rye and barley. It is the precursor of various industrial products, including polymers and plasticizers, and is also part of many hair and skin conditioning agents. Ren two is used to treat mild to medium acne, including acne acne and inflammatory acne. It belongs to a category of drugs called di carboxylic acid.

Evaluation 15%Ren Diexicate Gel (AZA) and the curative effect of non -therapy in the maintenance treatment of female adult acne, and compare it with 0.1%Adapalene gel (AD) The efficacy and safety of 6 months). This researcher's blind method was included in 55 women aged 18 to 45 years old with adult acne and randomly divided into three groups. They accepted AZA gel for 9 months per day (AZA9M, N = 17) Or AZA gel was treated twice a day for 3 months, and then a 6 -month observation period (AZA3M, N = 19) or AD gel for 9 months per day (AD9m, N = 19). The parameters of the efficacy, safety and patient related factors were analyzed.
A Thielitz and others studied that AZA15%gel is a safe and effective treatment and maintenance method. The effect of controlling inflammatory acne is not inferior to AD 0.1%gel. Studies have shown that 15% Ren di -acid gel and 0.1% Adapalene gel have roughly the same effectiveness.
( 2) Ren diexic acid vsadapalene treatment pigmentation: Which is better?
Rener acid is used to treat skin pigmentation, including excessive pigmentation after melasma and inflammation, especially those with darker skin tone. It has been recommended as a substitute for phenylphenol. As a tyrosinase inhibitor, Renxin acid will reduce the synthesis of melanin.
W K Jacek et al. Evaluation 0.1% Topical adapalene gel treats the efficacy and safety of ordinary acne in South Africa patients. South African blacks in 65 years between the 65-year-old ADAPALENE gels were conducted in the 12-week. All patients suffer from mild to moderate facial acne defined by the Leeds scoring system; they are instructed to apply drugs once a day. Rating the number and severity of the lesion in the 4th, 8th and 12th weeks. Studies have found that 0.1%Adapalene gel is an effective and tolerated black local treatment drug. It can reduce inflammation and non -inflammatory lesions, and prevent and relieve acne -related pigmentation.
