SepiWhite (INCI: Undecylenoyl Phenylalanine) is a bioactive, skin-brightening ingredient developed by a French specialty chemicals company. Chemically, it is a lipoamino acid derived from phenylalanine, an essential amino acid, and undecylenic acid, a fatty acid. It exists as a white, odorless powder that is water-soluble and stable across a wide pH range, with optimal performance in slightly alkaline conditions.
Notably, it is Ecocert-certified, free from preservatives, and compatible with various cosmetic ingredients, making it suitable for clean beauty formulations. It acts as a next-generation skin brightening active that effectively targets hyperpigmentation and uneven skin tone.
This clinically-proven ingredient works by inhibiting melanin synthesis at its source, reducing the appearance of dark spots, age spots, and post-inflammatory hyperpigmentation for a radiant, even complexion.
Blocks tyrosinase activity more effectively than conventional ingredients to ensure superior radiance.
