Improvements in skin quality parameters in postmenopausal participants after use of topical growth factor serum.

Abstract

Photodamage can induce skin aging processes that can be particularly concerning for postmenopausal women. Growth factors from hypoxic human fibroblast-conditioned media have demonstrated improvements in skin quality parameters. The aim of the study was to assess efficacy and tolerability of topical combination-treatment hypoxic growth factor serum (TNS A+) in postmenopausal women with moderate to severe facial photodamage. In this 12-week, open-label, single-center study, participants used TNS A+ serum twice daily. Postmenopausal women (40-65 years of age) with Fitzpatrick skin types I-VI and modified Griffiths scale scores 4-9 were eligible. Clinical and participant-reported assessments were evaluated at Weeks 6 and 12. Statistical significance was defined as p≤ 0.05. There were 17 enrolled participants. TNS A+ treatment demonstrated significant improvements from baseline in fine lines and wrinkles in periocular, forehead, and cheek areas at Week 12 and the perioral area at Weeks 6 and 12. Significant improvements from baseline in coarse lines and wrinkles were observed for the perioral area at Week 12 and periocular and cheek areas at Weeks 6 and 12. Improvements in overall photodamage, skin tone evenness, and tactile roughness were significantly greater at Weeks 6 and 12 versus baseline. Most participants reported TNS A+ made their skin look and feel smooth, soft, and rejuvenated; improved skin radiance; made lines and wrinkles less apparent; and improved skin texture. No treatment-related adverse events were reported. The TNS A+ regimen was well tolerated and provided significant improvements in skin quality in postmenopausal women with moderate to severe facial photodamage.
