01

What it does

How retinol works

Retinol is a form of vitamin A. It speeds up cell turnover and supports collagen, which can smooth texture, fade marks and help prevent clogged pores over three to six months.

02

Getting started

A beginner retinol schedule

Low strength

Begin with 0.1–0.3% retinol or a gentle retinal.

Two nights a week

For two weeks, then three, building only if skin stays comfortable.

Pea-sized amount

Enough for the whole face; avoid eyelids and the corners of the nose and mouth.

Sandwich method

Moisturiser, retinol, moisturiser to buffer irritation.

Morning SPF

Retinol makes skin more sun-sensitive; daily sunscreen is essential.

03

Expect

Normal and not normal

Mild dryness

Some flaking in the first weeks is common; reduce frequency.

Burning or swelling

Stop and let the barrier recover before trying again.

04

Caution

Who should wait

Avoid retinoids if pregnant, trying to conceive or breastfeeding, and check with a doctor if you use prescription acne treatments. Do not combine with strong acids on the same night.
