Malic Acid
Ingredient Info
Malic acid is an alpha-hydroxy acid (AHA) derived from apples that works as a gentle chemical exfoliant. It helps remove dead skin cells from the surface and can improve skin texture and appearance.
Benefits
- Gently exfoliates dead skin cells
- May improve appearance of uneven skin tone and texture
- Can help reduce visibility of acne and keratoses
- Less irritating than stronger AHAs like glycolic acid
Potential concerns
- Can cause burning, swelling, or itching in sensitive individuals
- May increase sun sensitivity—sunscreen use recommended
- Higher concentrations carry greater risk of irritation
- Not suitable for very sensitive or compromised skin barriers
Science: Malic acid is a well-established AHA used in cosmetic formulations as a peeling agent. Research indicates that AHAs' safety profile and skin benefits are concentration-dependent; lower concentrations are gentler while higher concentrations carry increased risk of adverse reactions including irritation and potential photosensitivity concerns.
