NAD⁺-boosting longevity serum powered by RejuveNAD™ — a clinically studied botanical extract from organic sunflower sprouts that targets the root causes of skin ageing at a cellular level for a visibly firmer, plumper and more youthful complexion. Oio Lab's Intercellular. Longevity Facial Serum is built around RejuveNAD™ — a cutting-edge extract derived from organic sunflower sprouts and shown to boost NAD⁺ levels in the skin. NAD⁺ (Nicotinamide Adenine Dinucleotide) is known as the 'longevity molecule' — a coenzyme essential for cellular energy production, DNA repair and skin rejuvenation. As NAD⁺ levels naturally decline with age, skin loses its ability to renew and protect itself. RejuveNAD™ targets five of nine biological hallmarks of ageing, working to counteract this decline and restore the skin's peak condition — with results showing skin can appear up to 8 years younger. Alongside RejuveNAD™, the formula delivers a vegan collagen complex rich in spermidine for elasticity and resilience, pomegranate seed stem cell lysate to promote radiance and an even tone, and ultra-pure ozonated omega 3, 6 and 9 esters for deep nourishment — all within a lightweight, milky texture that is 99.2% natural origin, free from synthetic fragrance and preservatives, and suitable for all skin types including sensitive skin and the eye area. Clinical results: +36% hydration and +25% skin smoothness after a single application. +22% firmness and -9% wrinkle depth after 28 days. 86% saw visible skin improvement within 7 days. 70% reported their skin looked its best after continued use.
