This exploratory study aims to evaluate the effects of the test product RV5026B - ET1732 on erythema, as well as on the sensations of discomfort and relief perceived in subjects with erythrocouperose and associated pityriasis folliculorum. We wish to evaluate: * firstly the test product alone in order to quantify the effects on the signs \& symptoms on the entire face, * then the contribution of the test product in addition to a reference topical treatment. The test product RV5026B - ET1732 was developed to: * Reduce redness, even if it has already set in, and help limit its reappearance * Soothe the sensations of heating and discomfort associated

Erythema score
Assessed by the investigator according to the Investigator Global Assessment - IGA - scale (score from 0 to 3: None toSevere) on each side of the face
Time frame: Day 1, Day 29 & Day 57
Overall dynamic efficiency score
Assessed by the investigator according to Investigator's Global Assessment (IGA) - (-3 to +3) (Very significant worsening = -3to Very significant improvement = +3) compared with baseline status at visit 1 on each side of the face
Time frame: Day 29 & Day 57
Demodex density
assessed by Standardized Skin Surface Biopsy (SSSB1 \& SSSB2 and SSSB1+2) on each hemiface by on-site optical microscope count, then protein analysis on SSSBs sample
Time frame: Day 1, Day 29 & Day 57
Rating of the intensity of the erythema
(score from 0 to 100) by centralized a posteriori analysis of the photographs taken on each side of the face, carried out by an expert dermatologist using software presenting the images taken for each of the subjects, blindly
Time frame: Day 1, Day 29 & Day 57
Flush score
Score over the last 3 days preceding the assessment according to the Global Flushing Severity Score - GFSS - numerical scale (score from 0 to 10 - None to Extreme: ) on each side of the face
Time frame: Day 1, Day 29 & Day 57
Dynamic SGA (subject global assessment) scale
Scale with 7 points (-3 to +3) (Very significant worsening = -3 to Very significant improvement = +3) in comparison with the initial state of visit 1 on each side
Time frame: Day 1, Day 29 & Day 57
Subject acceptability questionnaire
assessed by the subject with subject's questionnaire
Time frame: Day 29 & Day 57
Tolerance of the products for 2 months of use by adverse events
Recording of Adverse events
Time frame: Day 1, Day 29 & Day 57
Tolerance of the tested product for 2 months of use by global tolerance per subject
assessed by the investigator for both groups and per subject, considering all individual AE and their characteristics, based on a 5-point scale (0=Bad tolerance, 4= Excellent tolerance)
Time frame: Day 29 & Day 57
Subject's compliance regarding the test product
The subject will report his compliance in a subject's diary.
