How to Layer Serums in Correct Order
Thinnest-to-Thickest Rule
Apply serums from thinnest to thickest consistency for proper penetration.
Correct Order
- 1. Vitamin C on clean dry skin, wait 1-2 min
- 2. Hyaluronic acid on damp skin
- 3. Niacinamide after HA absorbs
- 4. Retinol at night only
Combinations to Avoid
Do not layer vitamin C with retinol. Use vitamin C in morning, retinol at night. Allow 60-90 seconds between each serum layer.
