The short answer

Best AHA exfoliants: The Ordinary Glycolic Acid 7% Toner ($10, daily use), The Ordinary Lactic Acid 10% ($8, gentler), Sunday Riley Good Genes Lactic Treatment ($122, premium), Naturium PHA Toner ($16, sensitive), and SkinCeuticals Glycolic 10 Renew Overnight ($90, pharma-grade).

AHAs (alpha hydroxy acids) work on the skin’s surface — perfect for texture, dullness, and post-acne marks.

The AHA hierarchy

The short answer

The AHAs ranked by gentleness: gluconolactone (PHA) gentlest, lactic acid mid-strength (also hydrating), glycolic acid strongest (deepest penetration), and mandelic acid (gentle for sensitive skin). Use 5-10% concentration; over 10% gets aggressive.

How to use AHAs

The short answer

Apply AHAs to clean dry skin in the evening. Start 2-3x weekly. Don’t combine with retinoids same night (alternate nights). Always use SPF 30+ next day — AHAs increase photosensitivity.

Frequently asked

AHA or BHA — which should I use? +

AHA for surface texture and pigment. BHA (salicylic) for pores, oily skin, and acne. Many people use both on different nights.

Can I use AHA daily? +

Some 5-7% formulations are daily-friendly (The Ordinary 7% glycolic). Stronger 10%+ products: 2-3x weekly max.

Do AHAs cause skin thinning? +

No — they thin only the dead-cell stratum corneum, while thickening the live epidermis below. Same as retinoids.
