What to look for in a Retinol Serum

Retinol accelerates cell turnover, smooths fine lines, and improves texture. Start low to avoid irritation; build tolerance over weeks.

Quick checklist

• Strength: 0.1–0.3% for beginners; 0.5–1% for experienced users.
• Formulation: encapsulated retinol is gentler; retinaldehyde is closer to tretinoin.
• Frequency: 2–3 nights a week to start; increase as tolerated.
• Sun protection: retinol increases photosensitivity: SPF is non-negotiable.
