Alpha hydroxy acids (AHAs)
Alpha Hydroxy Acids Are Key to Surface Skin Renewal
Alpha hydroxy acids, or AHAs, are a group of water-soluble exfoliants that work on the surface of the skin. They loosen the bonds between dead skin cells, allowing them to shed more easily and reveal fresher, smoother, and more radiant skin underneath.
AHAs are ideal for targeting dullness, uneven texture, fine lines, and pigmentation. They also help boost collagen production, making them a go-to for anti-aging and brightening treatments. Because they stay on the skin’s surface, AHAs are better suited to normal to dry skin types, especially when hydration and glow are the goal.
Common AHAs used in skincare:
- Glycolic Acid – from sugarcane; effective and fast-penetrating
- Lactic Acid – from milk or fermented sugars; gentle and hydrating
- Mandelic Acid – from bitter almonds; mild and suitable for sensitive skin
- Citric Acid – from citrus fruits; brightening and pH balancing
- Malic Acid – from apples and pears; mild exfoliation and hydration
Where are AHAs derived from?
While often synthetically produced for stability, natural sources include sugarcane, milk, citrus fruits, apples, grapes, and fermented plant sugars.
Bottom line: AHAs exfoliate the skin’s surface for a smoother, brighter complexion—ideal for dryness, dullness, and pigmentation. Unlike BHAs, they don’t penetrate deep into pores, making them best for surface-level renewal.
