Who participated in the test
A total of 78 consumers were selected through a screening questionnaire to ensure relevance. Each tester received three products and used them for four weeks, allowing for meaningful evaluation of both immediate and cumulative effects.
ATO line
Forty testers with active mild‑to‑moderate atopic dermatitis used the ATO routine: Wash Gel, Hydra Body Cream and Probiotic Repair Cream. The full routine was applied in the evening, with the probiotic cream reapplied as needed.
ACN line
Thirty‑eight testers with mild‑to‑moderate acne used the ACN routine: Micellar Water, Exfoliating Wash and Probiotic Repair Cream. Products were used twice daily, morning and evening.
Overall performance: strong advocacy and high satisfaction
Across both lines, testers rated products on a 1–5 scale and indicated whether they would recommend them. Advocacy was measured using Net Promoter Score (NPS).
The ATO line stood out with exceptionally high scores, while the ACN line also performed strongly.
