Buying Guide
What should you consider when choosing a brightening serum?
- Primary brightening ingredient: Alpha arbutin, beta arbutin, vitamin C, tranexamic acid, and niacinamide are common choices. Choose based on your sensitivity, skin type, and target concerns (dark spots, dullness, or overall brightness).
- Hydration needs: If you have dry skin, prioritize serums with hyaluronic acid or glycerin to avoid adding dryness while brightening.
- Sensitivity and irritation: Start with lower concentrations or patch test; some actives can cause irritation for sensitive skin.
- Texture and layering: Lightweight serums layer well under moisturizers and sunscreen. Capsule formats offer controlled dosing but may feel different to apply.
- Consistency and results timeline: Brightening results often require several weeks of consistent use. Look for a routine that you can maintain daily.
- Storage considerations: Vitamin C serums can degrade with heat/light; store in a cool, dry place to preserve efficacy.
