Nanovetores’ innovative encapsulation system enhances the delivery of Cysteamine with increased cosmetic efficacy and stability, ideal for treating hyperpigmentation and melasma. This advanced technology offers several benefits: it significantly reduces the characteristic odor of Cysteamine, stabilizes the active ingredient, and improves its permeation and diffusion through the skin layers. Additionally, it ensures controlled release, enhances illuminating efficacy, reduces irritation, and promotes better treatment adherence. Moreover, it supports the maintenance of the skin’s barrier function, preventing trans-epidermal water loss.
