AHA, BHA, PHA and LHA Explained

  • AHA (glycolic and lactic acid) is water-soluble and works on the skin's surface. Best for dull, rough-feeling or uneven-looking skin.
  • BHA (salicylic acid) is oil-soluble, so it can work inside pores. Best for oily skin and the look of blackheads.
  • PHA has a larger molecule and a gentler feel, often chosen for sensitive or dry skin.
  • LHA is a gradual exfoliant found in some Korean peeling gels.

Which Format to Choose

  • Toners and liquids: leave-on, easy to use a few evenings a week.
  • Pads: a measured amount, quick for busy routines.
  • Cleansers: the gentlest way to start, because they rinse off.
  • Ampoules and serums: more concentrated; use on alternate nights.

Using Acids Safely

Start two or three evenings a week, avoid layering several acid products, keep them apart from retinol nights, and wear sunscreen every morning.

Frequently Asked Questions

AHA or BHA for oily skin?

BHA, because it dissolves in oil and can work inside pores.

Can I use AHA and BHA together?

Some products combine them. With separate products, alternate them on different evenings.

Will acids make my skin sensitive to the sun?

They can, so daily sunscreen is important while you use them.
