Vitamin-Based Cosmeceuticals

Vitamins are popular ingredients in many over-the-counter (OTC) cosmeceuticals that are designed to improve various aspects of the skin’s appearance. In this article we aim to validate the clinical efficacy of vitamin-based skin care products, with a focus on vitamins A, C, B3, E, and K. We also provide a general overview of the cosmeceutical development process to promote a better understanding of product testing and the inherent limitations of the products. Ultimately, this information will help to elucidate the most beneficial vitamin-based cosmeceuticals that are supported with well-designed clinical studies.
