How to use

How to use

  • 1 Evening, start slow: Best in the PM a few times a week to begin with; avoid layering with other strong actives the same night.
  • 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

Pregnancy & breastfeeding

Contains ingredients some choose to avoid or double-check while pregnant or nursing.

Use with caution
BHA (salicylic) (Salicylic Acid)

Low-strength topical salicylic acid (BHA) is generally considered fine. Caution is usually reserved for high-strength leave-on products and salicylic peels.

This is general information, not medical advice. Pregnancy guidance varies and depends on concentration and your individual situation — always check with your doctor, midwife or pharmacist. How we flag this.

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

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.

Nicotinamide Mononucleotide, Niacinamide

BHA (salicylic) 0.5–2%

Salicylic acid is OTC-capped at 2%; 0.5–2% is the usual leave-on range. Much below that it acts more as a soothing agent than an exfoliant.

Salicylic 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.
