Cosmeceuticals in Dermatology

The document reviewed cosmeceuticals, which are products with both cosmetic and pharmaceutical properties, and their use in dermatology. It covered a range of ingredients, including antioxidants, growth factors, peptides, and botanicals, and their potential skin health benefits. Antioxidants like vitamins A, B, C, and E were discussed for their roles in skin appearance and health, with vitamin E being well-tolerated orally but potentially causing dermatitis when applied topically. Other compounds such as alpha-lipoic acid, ubiquinone, and idebenone were noted for their antioxidant and skin improvement properties. The document also examined botanical extracts like Coffea arabica, green tea, and pomegranate for their anti-inflammatory and skin health benefits. Polyhydroxy acids were mentioned as effective moisturizers and antioxidants, while hypopigmenting agents like hydroquinone were under review for potential toxicity. The document concluded that while cosmeceuticals can offer benefits, they lack the rigorous testing of pharmaceuticals, and further research is needed to confirm their efficacy and safety.
