Retinol 101: Everything You Need to Know

Retinol has been clinically proven to reduce fine lines, boost collagen production, and improve skin texture. But it requires careful introduction to avoid irritation.

What is Retinol?

Retinol is a form of Vitamin A that accelerates cell turnover and stimulates collagen production. It's one of the most studied and proven anti-aging ingredients.

  • Improves skin texture and tone
  • Minimizes pores
  • Fades dark spots and hyperpigmentation
