retinol: the facts and science behind its effectiveness

Jul 9, 2024

Retinol—a well-known derivative of vitamin A—is a powerhouse ingredient in modern skincare. But what exactly does it do, and why is it so highly praised?

“Retinoids reduce fine lines and wrinkles by increasing the production of collagen. They also stimulate the production of new blood vessels in the skin, which improves skin color.”
Harvard Health

When applied topically, retinol penetrates the skin's outer layers to encourage the growth of new skin cells. This accelerated cell turnover process helps to:

  • Smooth out uneven texture
  • Minimize the look of fine lines
  • Fade dark spots and discoloration
  • Unclog pores and reduce breakouts

It’s no surprise that retinol remains one of the most researched and recommended ingredients by dermatologists worldwide.


How Retinol Helps Reduce Wrinkles and Fine Lines

The secret to retinol’s wrinkle-reducing magic lies in its ability to stimulate collagen synthesis. Collagen is the structural protein that keeps skin firm and youthful—but it naturally declines as we age.

“Retinoids can improve skin texture and reduce mottled pigmentation. They may also reduce roughness and increase collagen production.”
National Library of Medicine

With regular use, retinol can improve skin’s elasticity, tone, and overall resilience. You’ll notice a smoother texture and a reduction in the appearance of deep-set lines, especially around the eyes and mouth.


Retinol vs. Retinoids: What’s the Difference?

While both are forms of vitamin A, there are key differences:

  • Retinoids are prescription-strength and work faster—but often cause redness, dryness, and peeling.
  • Retinol is gentler, making it suitable for most skin types, including sensitive skin.
“While retinoic acid has greater potency than retinol, it is also more irritating. Retinol offers a balance of efficacy and tolerability.”
National Library of Medicine
