Cut through the noise — the definitive 2026 list of skincare actives with real clinical evidence: tretinoin, vitamin C, sunscreen, azelaic acid, and hydroxy acids.
The Six Actives That Actually Work
- Tretinoin (Rx retinoid) — gold standard for wrinkles, texture, acne
- Vitamin C (L-ascorbic 10–20%) — antioxidant, pigmentation
- Broad-spectrum SPF 30–50 — non-negotiable
- Azelaic acid 15% — rosacea, PIH
- Alpha and beta hydroxy acids — exfoliation, congestion
- Peptides & niacinamide — barrier and firmness support
Everything else is "supporting cast." Simplify, be consistent, wear sunscreen daily.
