Buying Guide: Vitamin C Serums For Combination Skin
- Active form and stability: Look for derivatives like sodium ascorbyl phosphate or ascorbyl glucoside that convert to active vitamin C on the skin and tend to be gentler for combination skin.
- Concentration and irritation: Higher concentrations (around 15-20%) can brighten effectively but may irritate sensitive areas. Start with lower concentrations and patch-test.
- Formulation and feel: Water-based serums are typically lighter and better for oilier zones, while hyaluronic-acid-containing blends help hydration without heaviness for dry patches.
- Hydration balance: For combination skin, choose serums with humectants (hyaluronic acid) and emollients (jojoba oil, aloe) that don’t leave a greasy finish.
- Sun protection: Vitamin C works best when used with sunscreen in the daytime. Consider layering a broad-spectrum SPF after serum in the morning.
- Patch testing: Especially for sensitive skin, test on a small area for 24-48 hours before full-face use.
