Export Record: Globally trusted and exported for years with batch-to-batch stability.
INCI Name: Hydroxypropyl Tetrahydropyrantriol
Synonyms: Pro-xylane, C-beta-D-xylopyranoside-2-hydroxypropane, C-Xyloside
Molecular Weight: ~200
Appearance & Purity: High-purity white powder with minimal color and a neutral, ultra-light scent—industry-standard indicators of superior raw material quality.
Pro-Xylane is a powerhouse anti-aging active renowned for delivering results comparable to retinol and peptides, but with exceptional skin-friendly mildness.
Comprehensive Anti-Aging: Visibly improves facial sagging, skin laxity, radiance, and uneven skin tone.
Boosts Collagen Synthesis: Stimulates key basement membrane proteins (Type IV and Type VII collagen) to strengthen the dermal-epidermal junction and improve structural firmness.
Increases Moisture & Elasticity: Stimulates glycosaminoglycans (GAGs), proteoglycans, and endogenous hyaluronic acid to lock in hydration and smooth fine lines.
Accelerates Skin Repair: Promotes fibroblast growth factor regeneration to thicken the epidermis, reinforce the skin barrier, and enhance overall resilience.
Its two main functions are to maintain skin elasticity and address signs of aging. You can find it in the ingredient list of many advanced cosmetics.
Its efficacy can be ranked alongside that of retinol and peptides, but Hydroxypropyl Tetrahydropyrantriol is exceptionally mild on the skin.
