How to use
General guidance from this product's category and active ingredients — always follow the directions on the package.
Trust & honesty
The concentrations these actives are typically effective at in research — not a measurement of this product.
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.
