Sandwich Method
Sandwich Method — a layering technique in which a potent active is applied between two layers of a gentler product, usually moisturizer, to cushion its effect. It is frequently used with retinoids or exfoliating acids to improve comfort while still delivering the active.
Key points
- It typically means moisturizer, then the active, then moisturizer again.
- The goal is to reduce irritation, dryness, or stinging from strong ingredients.
- It is popular for easing sensitive skin into retinoids and acids.
- It is a form of buffering and can be paired with lower strengths or less frequent use.
Frequently asked
Does the sandwich method reduce how well an active works?
It may slightly dilute or slow the effect, but the added comfort often helps people use the active more consistently over time.
Which products work best for the sandwich method?
A simple, fragrance-free moisturizer is commonly used as the cushioning layers because it supports the barrier without adding extra actives.
