AHAs benefits for skin: what it does and who it suits
Short version: the job of AHAs is to loosen the dull top layer of dead cells to reveal a smoother, brighter surface. Long version below — including who should be careful.
What AHAs actually does
Category: alpha hydroxy acids. In a cosmetic routine the job of AHAs is to loosen the dull top layer of dead cells to reveal a smoother, brighter surface, which fits its stated use: surface exfoliation.
Typical strength: 5–10% for home use. Best used evening.
What you can realistically expect
Timeline: two to four weeks for glow, ten weeks for texture. Typical sensation: light tingle for a minute; stinging that lingers is too strong.
A popular belief is that higher strength gives a bigger glow; in reality overdoing it thins the barrier and gives temporary shine that fades into dullness.
Who it suits, and who should wait
Best for dull, rough or sun-exposed skin; not for reactive skin. Night use, SPF mandatory.
Take extra care with retinol the same night.
How to spot a good product
Look for glycolic, lactic or mandelic acid with a stated percentage and pH. Skip formulas where AHAs appears after fragrance and preservatives.
Practical tip: use SPF the next morning every time.
Who should tweak what
The same ingredient behaves differently on different skin, so adapt the schedule rather than the product.
What to look for before you buy
Spend thirty seconds with the back of the pack before spending money on the front.
