How to use

How to use

  • 1 Where it fits: Apply after toner and before moisturiser — thinnest to thickest.
  • 2 Morning & evening: Suitable for both AM and PM use.

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

Trust & honesty

Officially notified as a cosmetic in Malaysia (NPRA). Government registration record.

Effective levels — general guide

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

Niacinamide 2–5% (up to 10%)

Most research uses 2–5%; some formulas go to 10%. Very high levels can cause flushing in sensitive skin.

Niacinamide

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.
