BelleNAD+ is built on the central role of NAD+ in cellular energy metabolism and skin homeostasis. As a key regulator of mitochondrial function, NAD⁺ supports ATP production, redox balance, and DNA repair, all of which are essential for cellular renewal and resistance to oxidative stress. The inclusion of NMN sustains intracellular NAD⁺ availability, helping restore metabolic activity in aging and energy-depleted skin cells.
PN and PDRN complement this bioenergetic core by stimulating fibroblast activity and extracellular matrix remodeling through adenosine A₂A receptor activation, promoting collagen synthesis and tissue regeneration.
Multi-molecular hyaluronic acid optimizes the dermal microenvironment by supporting hydration and viscoelastic balance, while Complexia 55™ supplies essential nutrients required for enzymatic function and sustained cellular efficiency, reinforcing long-term skin vitality.
