A 4-weeks Comparative Study of Cosmetic Product Versus Standard Medical Care in Subjects With Seborrheic Dermatitis

May 4, 2026 updated by: Pierre Fabre Dermo Cosmetique

A Randomized Comparative Study to Evaluate the Efficacy of the Shampoo RV5263A - WS0060 Applied for 4 Weeks in Adults Subjects With Recurrent Squamous States of Seborrheic Dermatitis in Comparison to Standard Medical Care and a Cosmetic Shampoo

The aim of this study is to evaluate, with clinical and biological assessment methods, the effectiveness of the tested cosmetic product applied during 4 weeks of intensive treatment and compared to a Standard Medical Care (medicine shampoo) and to a comparative cosmetic shampoo, on mild to moderate recurrent squamous states of seborrheic dermatitis.

Study Overview

Detailed Description

This study is conducted as a monocentric, randomized, controlled and blinded-label study, in parallel groups.

A total number of 90 subjects included and randomized in 3 parallel groups:

  • Test group RV5263A - WS0060 cosmetic product
  • Comparative group: RV5263A - LC3302 cosmetic product
  • Standard medical care group

    6 visits are planned:

  • Visit 1: Inclusion (Day 1)
  • Visit 2: Intermediate visit (Day 4)
  • Visit 3: Intermediate visit (Day 7)
  • Visit 4: Intermediate visit (Day 15 ± 1 day)
  • Visit 5: Intermediate visit (Day 22 ± 3 days)
  • Visit 6: End-of-study visit (Day 29 ± 3 days)
