Retinol is generally a leave-on treatment, but its exact position, frequency and compatible layers depend on the finished formula and its directions.
Use the product label as the sequence
- Cleanse as needed.
- Apply retinol at the point specified by the manufacturer.
- Use compatible moisturizer when directed or needed.
- Use sunscreen in the morning according to its label.
There is no universal escalation schedule
Strength, vehicle, dose and frequency vary across cosmetic and prescription retinoids. Do not copy a fixed nightly schedule from an article or combine multiple retinoids automatically.
Other actives need a separate review
Exfoliating acids, benzoyl peroxide and other potentially irritating treatments may require separation or professional advice depending on the exact products.
Check special circumstances
Follow prescriber instructions for prescription retinoids. Ask an appropriate healthcare professional about pregnancy, breastfeeding, eczema or a significant reaction.
