7% AHA exfoliating liquid that helps smooth texture and reduce whiteheads.
Gentle chemical exfoliating essence formulated with 7% AHA (glycolic acid) to help remove dead skin cells and improve the overall appearance of skin texture. The lightweight liquid works to gently exfoliate the skin’s surface, helping reduce the look of whiteheads and clogged pores while promoting a smoother, clearer complexion.
The formula helps dissolve buildup of dead skin cells that can lead to dullness and uneven texture. With regular use, the skin may appear brighter, smoother, and more refined while supporting the natural skin renewal process.
Despite its exfoliating action, the lightweight liquid absorbs comfortably into the skin and can be incorporated into a consistent skincare routine to help maintain clearer and healthier-looking skin.
It is suitable for adults (18+), especially for oily, combination, and acne-prone skin, when dealing with whiteheads, rough skin texture, or dull skin that needs gentle chemical exfoliation.
