The Science of Anti-Aging: What Really Works?

Skin aging is driven by two processes: intrinsic aging (genetic, unavoidable) and extrinsic aging (UV exposure, pollution, lifestyle). The good news is that extrinsic aging, which accounts for around 80% of visible changes, is largely preventable and partially reversible.

What the Evidence Supports

Retinoids remain the most evidence-backed topical for stimulating collagen and accelerating cell turnover. Broad-spectrum SPF 50 sunscreen applied daily is the single most effective anti-aging intervention. Beyond topicals, collagen-stimulating procedures like radiofrequency, microneedling RF, and fractional CO2 laser have robust clinical data.

What Does Not Work

Most stem cell creams and collagen supplements applied topically cannot penetrate the dermis at effective concentrations. Save money on marketing-heavy products and invest in proven actives.
