Ageing Skin Care – Know More About Common AHA Molecules
Alpha Hydroxy Acids (AHAs) have become a cornerstone in anti-aging skincare, showing up in cleansers, serums, creams, and even professional treatments. These natural acids help exfoliate, smooth, and rejuvenate the skin, making them a favorite in the fight against fine lines, dullness, and uneven texture. Let’s explore some of the most common AHA molecules and their benefits.
Glycolic Acid
Glycolic acid, derived from sugarcane, is one of the most popular and effective AHAs. Its small molecular size allows it to penetrate deeply into the skin. By loosening the bonds that hold dead skin cells together, it promotes faster exfoliation, leaving the skin smoother and brighter.

Treats blackheads and controls excess oil

-
Improves absorption of other skincare ingredients
-
Keeps skin hydrated and may lighten dark spots
Lactic Acid
Lactic acid, derived from milk, has been used for centuries (think Cleopatra’s milk baths). It’s a gentle exfoliator and natural humectant, meaning it helps skin hold on to moisture. It’s often combined with other AHAs for enhanced results and is well-suited for sensitive or dry skin types.
Citric Acid
Found in citrus fruits, citric acid is a powerful antioxidant that helps neutralize free radicals responsible for skin aging. While not as strong an exfoliator as glycolic or lactic acid, it supports collagen production and can help fade pigmentation or dark spots.
Malic & Tartaric Acids
These AHAs, derived from apples (malic) and grapes (tartaric), are less commonly used on their own but are often included in multi-acid formulations. When blended, they enhance exfoliation and provide multiple skin benefits, such as improved tone and texture.
Important Note
While AHAs are highly effective, they can increase skin sensitivity to the sun. Always pair them with a broad-spectrum sunscreen to protect your skin from UV damage.
