How to use

How to use

  • 1 Where it fits: Apply after toner and before moisturiser — thinnest to thickest.
  • 2 Evening, start slow: Best in the PM a few times a week to begin with; avoid layering with other strong actives the same night.
  • 3 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.

Vitamin C (ascorbic) 5–20%

L-ascorbic acid is usually used at 5–20% (around 10–15% is common). Above ~20% adds little and tends to irritate more; it also needs a low pH to work.

3-O-ETHYL ASCORBIC ACID

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.

Glycolic 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.
