In-Use Tolerance Study Under Dermatological and Pediatric Controls of Sunscreen in Children With Atopic Dermatitis

Atopic dermatitis is a chronic skin condition that necessitates sun protection, yet there is limited research on the effectiveness of sunscreens and skin tolerance in Atopic Dermatitis.

Objectives: This study aims to evaluate the tolerance of a broad-spectrum SPF50+ sunscreen in children with Atopic Dermatitis, monitored through dermatological and pediatric assessments.

Methods: This study is conducted on 22 children with Atopic Dermatitis confirmed using the SCORAD index (15-25).

The protocol includes 2 visits and assessments as follow:

• Visit 1: Inclusion (Day 1) - Before and immediately after application (10 to 30 minutes), the investigator conducts a clinical evaluation of the dermatological tolerance of the investigational product. SCORAD evaluation by the dermatologist and pediatrician together is performed on Day 1.
• Home Application Period: Day 1 to Day 22 - Continued application of the sunscreen at home in real conditions of use
• Visit 3: End of Study (Day 22) -The investigators conduct a clinical evaluation of the dermatological tolerance of the investigational product. In addition, a questionnaire is used to evaluate global and perceived efficacy of the sunscreen.

Non-Inclusion Criteria:

Criteria Related to Population:

Criteria Related to Subject's Health:
