The sandwich method places moisturizer before and after a cosmetic retinol. It is an optional layering approach, not a guarantee against irritation and not a substitute for product or prescriber directions.
The basic sequence
- Cleanse and allow skin to dry as directed.
- Apply a compatible moisturizer.
- Use the retinol only in the amount and frequency on its label.
- Add moisturizer again if the routine and directions allow it.
It can change delivery and feel
Layering may alter how a product spreads or feels, but evidence and formulation vary. Some products already contain an emollient base or have directions that should not be modified.
Do not use it to justify overuse
More retinol, more frequent use or combining several strong actives can still cause irritation. Prescription retinoids require individualized instructions.
Check special circumstances
Ask an appropriate healthcare professional about pregnancy, breastfeeding, prescription treatment, eczema or a significant reaction.
