How to Use

Apply pea-sized amount to dry face evening only. Start 2-3 times weekly, increase to nightly over 4-8 weeks. Always use SPF 30+ daily.

Never combine with: AHA/BHA, benzoyl peroxide, vitamin C (use AM/PM separation).

Pair with: hyaluronic acid moisturizer, ceramide-rich moisturizer, gentle cleansers.

What to Look For

  • Concentration appropriate for tolerance (start low)
  • Stable formulation (opaque packaging)
  • Squalane or oil-based for sensitive skin
  • Free of irritating fragrances

For most users, The Ordinary Retinol 0.5% is excellent entry point at value pricing.
