15 keto fluprostenol isopropyl ester (80 µgr/mL) gel for cosmetic eyelash growth and enhancement

Summary Background Eyelashes have both a protective and an aesthetic function. Hypotrichosis of the eyelashes may negatively influence an individual's self‐perception. Objective To evaluate efficacy and safety of topical administration of a new cosmetic preparation containing 15 keto fluprostenol isopropyl ester (80 µgr/mL) for the treatment of idiopathic hypotrichosis of the eyelashes. Methods This is a monocentric, double‐blind, vehicle‐controlled study. Forty patients (18 years) with idiopathic hypotrichosis (GEA 1 or 2), who also exhibit feelings of low confidence, based on the ESQ score, were divided into two groups. Group 1: twenty women treated with once‐daily 15 keto fluprostenol isopropyl ester gel and Group 2: twenty women treated only with the vehicle gel. Results Group 1: The average difference in eyelash length measured at the midpoint of palpebral margins between T0 and T2 for Group 1 was 1633 mm and for Group B was 0.25 ( P  < 0.0001). Comparing the ESQ questionnaires of Groups 1 and 2 from T0 to T2, only the 80% of the patients of Group 1 declared to dedicate less time to the application of cosmetic mascara, having longer and darker lashes at T2 vs patients of Group 2, of which only 20% reported longer and darker eyelashes at T2. About safety, only one patient of Group 1 experienced sensation of ocular sensation heaviness and headache. No other side effects were referred. Conclusions 15 keto fluprostenol isopropyl ester gel was effective in enhancing eyelash growth, with an excellent safety profile.
