Conditions
Brief summary
This study is exploratory, non-comparative and open-label, conducted in France. It aims to provide insights into the effectiveness and safety of RV3895A - RY1774, potentially benefiting participants by improving scar appearance and quality of life.The aim of this study is to evaluate the efficacy of the cosmetic product RV3895A - RY1774 on re-epidermised scars of the face and body following burns and surgical stitches in adults, adolescents and children over a 6-month follow-up period. Patients are divided into 2 groups: * Group 1: adults with: * Subgroup 1A: adults with post-burn scar(s) * Subgroup 1C: adults with post-surgical scar(s) requiring stitches to be inserted and removed if applicable (in the case of non-absorbable stitches). * Group 2: children and/or adolescents including children aged 2 to 7 years inclusive with: * Subgroup 2A: children/adolescents with post-burn scar(s) The study consists of 4 visits: Visit 1: Inclusion (Day 1), Visit 2: Intermediate visit (Day 22), Visit 3: Intermediate visit (Day 85), Visit 4: End-of-study visit (planned or anticipated) (Day 169 )
Interventions
The product is applied twice a day to the scar(s) under study, avoiding all contact with natural orifices (and avoiding ingestion by children in the case of application to the hands in particular). The product is applied using a specific massage technique developed for the product and which is explained by the investigator at visit 1. The product is applied in sufficient quantity to cover the application area.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Physical aspect of scar(s) compared to normal skin by the investigator | Day 1, Day 22, Day 85, and Day 169 | The investigator assessed the physical appearance of the studied scar(s) in comparison to normal skin using the POSAS Observer Scale (Patient and Observer Scar Assessment Scale) |
| Physical and functional aspect of scar(s) by the subject | Day 1, Day 22, Day 85, and Day 169, and monthly at home between Visit 2 and Visit4 | Subjects who were of age to complete the assessment evaluated the physical appearance in comparison to normal skin and the functional appearance of the studied scar(s) using the POSAS Patient Scale |
| Soothing effect | at Day 1 (before and after product application), Day 22, Day 85, and Day 169, and monthly at home between Visit 2 and Visit 4. | The subject/parent(s) or legal guardian(s) evaluated the soothing effect using a Numerical Rating Scale (NRS) to assess discomfort over the past 3 days (except for the evaluation at Day 1 after application) from 0 (no discomfort) to 10 (severe discomfort) |
| Inflammatory aspect of scar | at Day 1, Day 22, Day 85, and Day 169 | The investigator evaluated the inflammatory aspect of the scar using the vitropression test |
| Evolution of scar aspect compared to Day 1 | at Day 22, Day 85, and Day 169 | The investigator assessed the evolution of the scar's appearance compared to D1 based on all parameters evaluated in the study using a dynamic Investigator's Global Assessment (IGA) scale ranging from -1 (worsening), 0 (no change), 1 (slight improvement), 2 (clear improvement), 3 (very clear improvement) |
| Overall satisfaction with Test product (Investigator's assessment) | at Day 22, Day 85, and Day 169 | The investigator assessed overall satisfaction with the product's impact on scar appearance based on usual practice and study parameters using an NRS from 0 (not at all satisfied) to 10 (very satisfied) |

| Dermatology Life Quality Index (DLQI) | at Day 1, Day 22, Day 85, and Day 169 and monthly at home between Visit 2 and Visit 4 | Quality of life was assessed by subjects of appropriate age using the Dermatology Life Quality Index (DLQI) questionnaire |
| Specific impact of burns on quality of life | at Day 1, Day 22, Day 85, and Day 169 | For subgroup 1a (Burns) only : evaluated by subjects using the body image and heat sensitivity subdomains of the Burn Specific Health Scale-Brief (BSHS-B) |
| Visual aspect of the scar through illustrative photographs | at Day 1, Day 22, Day 85, and Day 169. | — |
| The quantity of product used calculated by weighing the tubes | Between Day 1 and Day 169 | — |
| Subjective cosmetic acceptability of the product | at Day 22, Day 85, and Day 169 | The subjective cosmetic acceptability of the product was evaluated by the subject/parent(s) or legal guardian(s) using a questionnaire |
| Recording of adverse events | at Day 1 (first application of the product on site), Day 22, Day 85, and Day 169 | At each visit, the occurrence of adverse events since the last visit was determined based on spontaneous reports from the subject/parent(s) or legal guardian(s), non-subjective questioning, and clinical evaluations performed by the investigator. All adverse events were recorded in the Case Report Form (CRF) |
| Overall tolerance assessed by the investigator | at Day 22, Day 85, and Day 169 | Overall tolerance was assessed by the investigator considering all individual adverse events and their characteristics, as well as past experience with similar products, using a 5-point scale (Excellent, Very Good, Good, Moderate, Poor) |
