Q. How do we know if peptides are delivered into the skin? A. We prove them with science — not assumption. ALTUM® Penetration Mechanism ALTUM® peptides penetrate the skin barrier. Glutathione in the skin breaks the chemical bond between the peptide and its carrier. The released peptides nourish fibroblasts in the dermis. This stimulates collagen production, improving skin elasticity. Peptide Release Test (36.5 °C, GSH concentration 0.3-0.5wt%) Clinical data shows that higher

Do you know the 500 Dalton Rule? “500 Dalton Rule” In dermatological science, the 500 Dalton Rule  states that molecules with a molecular weight exceeding 500 Daltons cannot effectively penetrate the stratum corneum — the skin’s outermost barrier. *Kraeling ME, Zhou W, Wang P, Ogunsola OA.
