Cosmeceuticals: Peptides, Proteins, And Growth Factors

The document discussed the role of cosmeceuticals, particularly peptides, proteins, and growth factors, in improving skin health and appearance by slowing skin aging. Peptides were noted for their ability to penetrate the skin and support collagen production, with different types offering various benefits, such as collagen synthesis stimulation and muscle relaxation. Products like Argireline® and Vialox® were shown to reduce wrinkles through neurotransmitter inhibition. Proteins enhanced skin hydration and scalp strength, while growth factors in products like TNS Recovery Complex demonstrated wrinkle reduction and skin texture improvement in small clinical studies. Despite challenges in skin penetration, growth factors showed benefits through absorption via sweat glands and hair follicles. The document highlighted the need for further research, especially double-blind, placebo-controlled studies, to confirm these findings.
