A topical gel containing a proprietary mixture of over 110 growth factors, cytokines, and soluble matrix proteins secreted by human dermal ﬁ broblasts was evaluated for safety and efﬁ cacy in the treatment of mild to severe facial photodamage. In a double-blind study, 60 subjects were randomly assigned to receive either active gel or the vehicle and applied twice daily for 6 months along with a moisturizing cleanser and sunscreen. Efﬁ cacy (proﬁ lometry, photography, and clinical assessment) and safety (adverse event reporting) measures were evaluated at 0, 3, and 6 months. Treatment with the active gel for 3 months produced greater reduction in ﬁ ne lines and wrinkles than the vehicle treatment as measured by objective and subjective assessment techniques. The results were either statistically signiﬁ cant (P≤.05) or trending towards statistical signiﬁ cance (P≤.1). This study demonstrates that addition of a topical formulation of growth factors and cytokines to a basic skin care regimen reduces the signs of photoaging.
