How to use

How to use

  • 1 Morning only: Apply as the last step of your AM routine, after moisturiser, and reapply every ~2 hours of sun exposure.
  • 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.

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

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.
