AHAs: The Complete Australian Guide
AHAs, or alpha hydroxy acids, are exfoliating ingredients used in skincare to help smooth rough texture, improve dull-looking skin and support a more even skin surface. Glycolic acid is one of the most well-known AHAs and is commonly used in body skincare for rough, bumpy and dry texture.
Quick Answer
AHAs are water-soluble exfoliating acids that work on the skin’s surface. They help loosen dead skin cell build-up, making them useful for rough body texture, keratosis pilaris, dry skin, strawberry legs and uneven-looking skin.
What are AHAs?
AHAs are a family of exfoliating acids used in skincare. They help support surface exfoliation by loosening the bonds between dead skin cells, allowing the skin to feel smoother over time.

- Mandelic acid
- Malic acid
- Tartaric acid
- Citric acid
Why glycolic acid is popular
Glycolic acid is one of the most widely used AHAs because it is effective for surface exfoliation. In body skincare, it is often chosen for rough texture, dullness, keratosis pilaris and uneven-looking skin.

Why pH matters with AHAs
AHA performance is not only about the percentage listed on the label. pH, formulation, supporting ingredients and usage frequency all influence how an exfoliating product behaves on the skin.

How to use AHAs on the body
- Start slowly, around 2–3 nights per week.
- Apply to clean, dry body skin.
- Avoid freshly shaved, broken or irritated skin.
- Pair with hydrating and barrier-supportive ingredients.
- Use SPF on exposed areas during the day.
Important: AHAs can increase sun sensitivity. Use sunscreen on exposed areas and avoid over-exfoliating.
