Collection: AHA

Alpha hydroxy acids (AHAs) are water-soluble exfoliating acids that remove dead skin cells from the skin's surface, helping improve rough texture, dullness, uneven skin tone, and the appearance of post-acne marks. Different AHAs vary in molecular size and strength, allowing some to exfoliate more intensely while others are better suited for sensitive skin.

This collection includes Korean skincare products formulated with alpha hydroxy acids such as glycolic acid, lactic acid, and mandelic acid. Products are selected based on ingredient composition rather than marketing claims.
