What it is
Retinol is a derivative of vitamin A and one of the most extensively studied skincare ingredients. It belongs to the retinoid family, which also includes tretinoin (prescription) and retinal.
How it works
Retinol converts to retinoic acid in the skin, which binds to retinoic acid receptors and triggers cell turnover, stimulates collagen production, and regulates sebaceous gland activity.
Best for
- ✓Fine lines and wrinkles (most evidence)
- ✓Uneven skin texture and rough skin
- ✓Acne-prone skin (regulates cell turnover)
- ✓Users willing to do a slow introduction
Use with caution if
- —Pregnancy or breastfeeding (consult your doctor)
- —Very reactive or compromised skin barrier — wait until barrier is repaired
- —Daytime use without SPF 30+ sunscreen
Layering notes
Use at night only. Start with 0.1–0.3% once weekly and increase frequency slowly over 8–12 weeks. Apply after cleansing and before moisturizer. Always use SPF 30+ the next morning.
