Brief summary: The aim of this exploratory study is to better understand the mechanisms of action of the RV3278B-OS0386 cosmetic product on the cutaneous ecosystem, in acne context.

Detailed description: This study will be conducted as an exploratory monocentric, randomized, comparative study.

A total number of 52 subjects (teenagers with mild to moderate facial acne) will be included and randomized in two parallel groups :

* The tested group who will apply the tested product RV3278B-OS0386
* The control group who will not apply the tested product. However, they will receive the associated product (RV4632A-RY1845), to be applied in the event of facial skin discomfort only.

  3 visits are planned:
  * Visit 1 (Day 1) : Inclusion, randomization, collection of biological samples on the forehead and start of product application.
  * Visit 2 (Day 29 +/- 3 days) : Phone call follow-up
  * Visit 3 (Day 57, a window of + 3 days is allowed): End-of-study visit - Collection of biological samples on the forehead.
