Introduction: Why Retinol Is the #1 Dermatologist-Recommended Active
Retinol – a vitamin A derivative – is the only over-the-counter ingredient clinically proven to reverse visible aging at the cellular level.
Unlike exfoliants (AHAs/BHAs), retinol works deep in the dermis to:
Stimulate collagen
Speed cell turnover
Repair DNA damage
Regulate oil
First studied in the 1980s for acne, retinol exploded into anti-aging when researchers discovered one nightly application = 5 years younger-looking skin in 12 months.
Whether you’re 20 (prevention) or 50 (repair), retinol is your non-negotiable for radiant, resilient skin.
How Retinol Works: The Cellular Transformation
Landmark Study: Journal of Investigative Dermatology (2023) – 0.4% retinol increased collagen by 38% in 6 months — matching prescription tretinoin.
