Erythorbic acid is a stereoisomer of ascorbic acid (Vitamin C), meaning it has a similar chemical structure but a different spatial arrangement. It functions primarily as an antioxidant and reducing agent in cosmetic formulations. It helps to protect the product from degradation due to oxygen exposure, thereby extending its shelf life.
