How to use

How to use

  • 1 Where it fits: Apply near the end of your routine, after thinner serums.
  • 2 Morning works well: Antioxidants like vitamin C pair well with daytime use under sunscreen.

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.

Ascorbyl Palmitate, Sodium Ascorbate, Ascorbic Acid (Vitamin C)

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.
