How to Choose

Start with Lower Concentrations

Actives like retinol, vitamin C, and acids should be introduced at beginner-friendly concentrations to avoid irritation. Your skin needs time to build tolerance.

How to Layer Serums

Apply after cleansing on damp skin. Use thinnest serums first (water-based), then thicker ones (oil-based). Wait 30-60 seconds between each to allow absorption. Seal with moisturizer and sunscreen.

Single-Active vs Multi-Active Formulas

Single-ingredient serums are easier to test and layer. Multi-active formulas can be convenient but make it harder to identify what works or irritates. Start simple.
