If you’ve ever wondered ‘What does AHA do for skin?’, the short answer is this: it helps remove dead skin cells, promote cell turnover and reveal a smoother, brighter complexion. Alpha Hydroxy Acids (AHAs) have become a staple in modern skincare for their ability to improve skin texture, tone and clarity, making them a powerful ingredient in treating dullness, uneven skin tone and signs of ageing.
But what exactly are AHAs, and how do they work?
Understanding Alpha Hydroxy Acids (AHAs)
Alpha Hydroxy Acids are a group of naturally occurring acids commonly found in fruits, milk and sugar cane. In skincare, they’re primarily used for their exfoliating properties. Some of the most common AHAs include:
-
Glycolic Acid: Derived from sugar cane, known for its small molecule size and deep penetration.
-
Lactic Acid: Derived from milk, offers gentle exfoliation and added hydration.
-
Citric Acid: From citrus fruits, often used for pH balance and brightening.

What does AHA do for skin? It promotes natural exfoliation and reveals a smoother, brighter complexion beneath the surface.
How AHA Works on Skin
AHAs work by loosening the bonds between dead skin cells on the skin’s surface, allowing them to shed more easily. This chemical exfoliation reveals fresh skin underneath and supports better absorption of other active ingredients.
Key skin benefits of AHA include:
-
Smoother skin texture
-
Brighter, more even tone
-
Improved hydration and product penetration
-
Reduced appearance of fine lines and pigmentation
-
Gentle resurfacing without physical scrubbing
Benefits of AHA in a Skincare Routine
Incorporating AHAs into your routine can support a wide range of skin concerns:
- Dullness: AHA clears away dead skin cells that can leave skin looking tired or ashy.
- Congestion and Breakouts: By keeping pores clear, AHAs can reduce blackheads and prevent build-up.
- Uneven Skin Tone: Regular use of AHA can help fade post-inflammatory pigmentation and sun damage.
- Ageing Skin: AHAs improve elasticity and reduce the visibility of fine lines through ongoing stimulation of collagen renewal.
Choosing the Right AHA for Your Skin
Not all AHAs are created equal. Some are better suited for sensitive skin (like lactic acid), while others (like glycolic acid) are ideal for more robust exfoliation. The key is finding the right concentration and formulation for your skin type and concerns.
What does AHA do for skin during cleansing? It removes dead skin cells and preps the skin for better absorption of active ingredients.
How to Use AHA Safely
Although AHAs offer clear benefits, they must be used properly to avoid irritation or sensitivity:
-
Start slow: Introduce AHAs gradually, 2 to 3 times a week and monitor your skin’s response.
-
Pair with SPF: AHAs can increase sun sensitivity, so daily sun protection is essential.
-
Avoid layering with strong actives: Using AHAs alongside retinol or vitamin C may cause irritation unless advised by a professional.
