How to use

How to use

  • 1 Morning only: Apply as the last step of your AM routine, after moisturiser, and reapply every ~2 hours of sun exposure.
  • 2 Wear SPF the next day: Acids and retinoids increase sun sensitivity — daily sunscreen is a must while using this.

General guidance from this product's category and active ingredients — always follow the directions on the package.

Trust & honesty

Effective levels — general guide

The concentrations these actives are typically effective at in research — not a measurement of this product.

AHA (acid exfoliant) 5–10% (OTC)

OTC leave-on AHAs are usually 5–10%. The effect also depends on pH and free-acid value, not the percentage alone.

Lactic Acid

INCI lists don't disclose amounts, and we don't claim to know this product's levels — these are the ranges these ingredients are usually effective at, so you can tell a real formula from "fairy-dusting" a marketed active. How we estimate this.
