- Brief Summary
Acne affects most adolescents and young adults with varying severity and presentation. For early or localized forms, the first-line treatment is usually local. The available treatments often lead to local irritation, particularly during the first few weeks of use. This is why creams containing exfoliating agents have long been used in acne, as they are considered to allow a faster disappearance of superficial lesions.
The objective of this 6-month double-blind study is to demonstrate in 100 acneic patients the interest of an anti-acne face cream as an adjunct to and in addition to a 5% benzoyl peroxide gel.
- Detailed Description
The study is conducted in accordance with the protocol and the legislative and regulatory provisions in force (after obtaining authorization of the French health authorities and the favorable opinion of the ethics committee).
Regarding the statistical analysis, two different analysis are performed:
* Descriptive analysis: quantitative variables are described by the mean and standard deviation and qualitative variables by the raw number of each modality and the corresponding percentage.
* Comparative analysis: for quantitative variables, inter-group comparisons are made by a Student's T-test or a non parametric Mann-Whitney test if necessary. For qualitative variables, comparisons are made using a Chi-square test, if the expected number of participants is less than 5, Fischer's exact test on a 4-box contingency tables is used.
A significant level of p \<0.05 is considered as significant. A double-data entry is carried out then a comparison of the two databases is performed. Finally internal and external consistency tests are planned. Missing data are described and possibly analyzed.
