Efficacy Study of Cosmetic Product RV3278AET0943 Versus Non-treated Group in Adults With Oily and Acne Prone Skin

The aim of this study is to evaluate, at different times, the RV3278A - ET0943 cosmetic product efficacy after 8 weeks of application on the face (twice-daily application). At T1 (Baseline), T2 (4 weeks) and T3 (8 weeks), the following assessments are performed:

* The reduction of the pilosebaceous follicular ostium size in vivo (pores) on the forehead * The clinical evaluation (count of non inflammatory and inflammatory acne lesions, IGA score) of the face * The reduction in visible follicles * The standardized numerical photographs of face and ¾ right and left profile in normal, parallel polarized, cross polarized and UV light * The analysis of the skin lipids of the forehead * The qualitative and quantitative analysis of the sebum and comedones constituents (nose wings)

This is a comparative, open-labelled study, on subjects with oily and acne prone skins on the face.

Each group includes 18 subjects.

About this study

This study is monocentric, comparative versus non-treated group, open-labelled, exploratory, conducted in adults having oily and acne prone skin.

The study includes 4 visits for each group, including subjects' selection:

  • V0: Subjects' selection
  • V1: Baseline inclusion
  • V2: 4 weeks, follow-up visit
  • V3: 8 weeks, study end

The maximal study duration is 61 days. The front, temporal areas and nose wings are defined as the study interest areas for superficial samples.

The evaluation is at 3 times: T1 baseline, T2 at 4 weeks and T3 at 8 weeks of application of RV3278A formula ET0943 with comparison of each time versus baseline.

There are twice-daily applications (morning and evening) of the test product on the face.

Treatment and study plan

Cosmetic product

Other

It is a comparative study with two parallel groups of subjects:

  • Tested group: twice daily application of the cream RV3278A cosmetic product on the whole face
  • Comparative group: no application of study product or reference product

Primary outcomes

  1. Efficacy of the product on lesions count (Lucky method)

    Time frame: Change from baseline to 8 weeks later, for each group

    Inflammatory and lesions quantification on the whole face

Secondary outcomes

  1. Efficacy of the product on lesions count (Lucky method)

    Time frame: Change from baseline to 4 weeks later, for each group

    Inflammatory and lesions quantification on the whole face

  2. Forehead acne lesions count (target area)

    Time frame: Change from baseline to 4 weeks and 8 weeks later for each group, on the target area

  3. Investigator Global Assessment (IGA) on 5-point scale

    Time frame: Change from 4 weeks to 8 weeks later, for each group, on the target area

    Clear = 0, Almost clear = 1, Mild = 2, Moderate = 3, Severe = 4

  4. Sebum harvest and analysis

    Time frame: At baseline and after one month of tested product treatment

    Quantification of free fatty acid (FFA) / triglyceride (TG) ratio by infrared spectroscopy: Forehead sebum was collected on absorbent paper then the lipid composition was analysed by infrared spectroscopy to determine the free fatty acids to triglycerides ratio

  5. Comedones lipid harvest and analysis

    Time frame: At baseline and after one month of tested product treatment

    Quantification of free fatty acid / triglyceride ratio by GC/MS: Samples were collected with patch on nose wings. Comedones were collected and lipids extracted according to the Bligh & Dyer (Bligh and Dyer, 1959). The biochemical exploration was performed by the screening of neutral lipids on GC/MS

  6. Skin lipids

    Time frame: Change from baseline to 4 weeks and 8 weeks later, for each group, on the target area

    Measure by FTIR spectroscopy (in vivo non invasive infrared analysis)

  7. Pilosebaceous follicular ostium size in vivo

    Time frame: Change from baseline to 4 weeks and 8 weeks later, for each group, on the target area

    Measure by confocal microscope

  8. Dilated pores on 5-point scale

    Time frame: Change from baseline to 4 weeks and 8 weeks later, for each group, on the target area

    Absent = 0, Very mild = 1, Mild = 2, Moderate = 3, Severe = 4

  9. Patient Global Assessment (PGA) on 6-points scale

    Time frame: Change from 4 weeks to 8 weeks later, for each group, on the target area

    Clear worsening = 0, slight worsening = 1, no change = 2, slight improvement = 3, clear improvement = 4, total improvement = 5

  10. Self product agreement questionnaire

    Time frame: At week 8, for tested group

    9-question questionnaire with a majority of scales ranging from 0 to 10 where 0 was the worst satisfaction and 10 the best one

  11. Visible follicles quantification by in vivo visualisation methods

    Time frame: Change from baseline to 4 weeks and 8 weeks later, for each group, on the target area

    Count by multispectral imaging
