Peptide-pro complex serum: Investigating effects on aged skin.

Abstract

Effective anti-aging treatments are an unmet consumer need. Ex vivoand clinical tests have evaluated the efficacy of a topical facial serum containing a proprietary blend of neuropeptides, proteins, amino acids, and marine extracts on aged skin. In the ex vivo study the facial serum was compared to a commercially marketed face serum and to an untreated control on skin explants using microrelief, smoothness, and epidermal thickness endpoints. The 12weeks monadic clinical study was designed for the test product to be used on the whole face. Subjects functioned as their own control; evaluating change from baseline. Skin was evaluated clinically by a Dermatologist for tolerability and for efficacy. Also part of the product assessment was skin hydration measurements, imaging, and a subject questionnaire. The facial serum improved skin condition by significant reductions in skin surface area occupied by microfolds and in skin roughness. Additionally, it increased epidermal thickness as compared to the untreated control as well as the commercially marketed face serum. The facial serum provided a statistically increased skin moisturization compared to pretreatment values. Dermatological evaluation of the skin concluded that there were statistically and clinically significant improvements in skin smoothness, wrinkles severity, fine lines visibility and lifting, and tightening effects at crow's feet area, forehead, and upper lip. A facial serum, containing a proprietary blend of neuropeptides, proteins, amino acids, and marine extracts, has been shown to improve the overall quality of aged skin in a series of ex vivo and clinical tests.
