Kojic Acid is a well-established cosmetic active used in brightening formulations for its ability to visibly improve the appearance of uneven skin tone, dark spots, and post-sun discoloration. It works by interfering with melanin synthesis pathways, making it a popular choice in tone-evening and brightening skincare products.
Studies have shown that Kojic Acid works well alongside Glycolic Acid, and the two are commonly combined in brightening formulations for enhanced results.
