How to use

How to use

  • 1 Evening: Use at night — start 2–3× a week and build up as your skin tolerates it.
  • 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.

Often avoided
Retinoids (Vitamin A) (Retinyl Palmitate)

Topical retinoids (retinol, retinaldehyde, retinyl esters) are widely advised against in pregnancy as a precaution. The strongest evidence is for ORAL retinoids; topical absorption is low, but most clinicians err on the side of caution.

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.

Retinoids (Vitamin A) 0.01–1%

Most studied between 0.1% and 1%. Higher is not automatically better — irritation climbs with dose, so a well-formulated lower strength is often the sweet spot.

Retinyl Palmitate

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.
