see the color of their lips improve at D56 (22 of 22, self-reported questionnaire)
Tested under dermatological supervision
01The method
A dermatologist who graduated from the Paris Faculty of Medicine, a medical doctor registered with the French Ordre des médecins and practicing in Paris, gave the N°3 Balm and the questionnaire to 23 of her patients. She followed all 23 from D0 to D56, with a check at D28: lip examination, photos and measurements, tolerance and efficacy. The photos and measurements are covered by medical confidentiality and are not published. Each person applied it for 56 days, from August 24 to October 19, 2026, most often morning and evening. Their LIPS-ID® score was measured at the start.
At D0, D28 and D56, the same questionnaire was filled in: texture, hydration, lip color, tolerance.
For the full five-step routine, see the LIPS-ID® study.
02The panel
23 people, men and women, aged 18 to 61. All six phototypes, I to VI, were represented. At the start, LIPS-ID® scores ranged from 2.0 to 10.
