What is Pro-Xylane?

Pro-Xylane is a patented anti-aging active ingredient widely used in cosmetic and dermatological skincare, especially in premium products from L’Oréal–affiliated brands.

What Pro-Xylane Is

Pro-Xylane (Hydroxypropyl Tetrahydropyrantriol) is a bio-derived sugar molecule originally developed by L’Oréal.

It is synthesized from xylose, a natural sugar found in plants (such as beech wood).

INCI name: Hydroxypropyl Tetrahydropyrantriol

How Pro-Xylane Works (Mechanism)

Pro-Xylane acts mainly on the extracellular matrix (ECM) of the skin:

• Stimulates glycosaminoglycan (GAG) production

• Improves proteoglycan synthesis

• Strengthens dermal–epidermal junction (DEJ)

• Helps maintain skin density and structural integrity

In simple terms: it helps the skin retain water, stay firm, and resist sagging.

Key Skin Benefits

• Improves skin firmness and elasticity

• Enhances skin density and thickness

• Reduces appearance of wrinkles and fine lines

• Provides long-term hydration support

• Helps with skin plumpness and resilience

It’s especially popular for anti-aging, lifting, and firming formulas.
