“I reversed my skin age by the equivalent of 9 years. Effectively freezing my skin aging over the past five years. Tretinoin is a core part of my skincare protocol.”

Why Tretinoin

Increases skin cell turnover. Improves photoaged skin.

Supports sun-damaged skin

In a 6-month trial of nearly 300 adults with sun-damaged skin, 68% using tretinoin showed overall skin improvement.

HOW WOMEN’S SKIN COMPLEX WORKS

Rebuilds collagen. Improves skin texture.

Tretinoin switches on genes responsible for producing collagen and regulating pigmentation. Niacinamide evens tone at the surface. Estriol hydrates the skin and increases elasticity. Finasteride blocks DHT, minimizing unwanted facial hair.

Women's Skin Complex (4-in-1)

Accelerates cell turnover

Dead skin cells shed faster. New cells reach the surface more quickly, improving texture and tone.

Stimulates collagen production

Fibroblasts are activated to produce new collagen, partially reversing structural damage from UV exposure.

Strengthens and restores skin

Estriol supports hydration and elasticity, while niacinamide strengthens the skin barrier, reduces redness, and brightens tone.
