Best AHA exfoliants: The Ordinary Glycolic Acid 7% Toner (under $25, daily use), The Ordinary Lactic Acid 10% (under $25, gentler), Sunday Riley Good Genes Lactic Treatment (under $150, premium), Naturium PHA Toner (under $25, sensitive), and SkinCeuticals Glycolic 10 Renew Overnight (under $100, pharma-grade).
AHAs (alpha hydroxy acids) work on the skin’s surface, perfect for texture, dullness, and post-acne marks.
The AHA hierarchy
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.

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.
