Abstract
Clinical Trial ID: NCT0454597 BACKGROUND: Mimetic wrinkles, commonly referred to as expression lines, form perpendicular to anatomical regions subjected to repeated facial muscle contraction. Neuromodulating peptides have biological activity and can offer a solution to those concerned with expression lines and facial aging. OBJECTIVE: The objective of this randomized, double-blind, placebo-controlled study was to assess the efficacy and tolerability of a line-targeting peptide serum (LTPS) as a stand-alone treatment in improving expression lines and skin health. METHODS: This was an institutional review board-approved study involving healthy subjects. Fifty-five female subjects, 35 to 60 years old, Fitzpatrick Skin Type I to VI, with mild to moderate global face fine lines and wrinkles were recruited. Subjects were randomized to apply LTPS or a placebo serum to their face twice daily for twelve weeks. Short-term efficacy was assessed after fifteen minutes of serum application at baseline. Long-term efficacy and tolerability, self-assessment questionnaire, and VISIA® clinical photography were performed at baseline, Weeks 4, 8, and 12. 3D PRIMOS CR imaging and wrinkle analysis were obtained at baseline and Weeks 8 and 12. RESULTS: The LTPS significantly improved expression lines at fifteen minutes (short term), Weeks 4, 8, and 12 (long term) when compared to the placebo serum as evaluated by a board-certified dermatologist. The LTPS significantly outperformed the placebo serum in improving skin parameters at all time points. VISIA and PRIMOS CR wrinkle analysis substantiated the LTPS's efficacy. LTPS was well-perceived and well tolerated by the subjects. CONCLUSION: This IRB-approved clinical study demonstrated that LTPS was effective in improving expression lines, wrinkles, and skin health after twelve weeks of application.
