NAD⁺ is an essential coenzyme that enables cells to produce energy, repair damaged DNA, and activate sirtuins—key proteins in regulating skin aging. Over time, its levels decrease significantly, resulting in duller skin, less resilience, and a reduced ability to recover.\u003c\/p\u003e\n\u003cp\u003eThe biotechnological-origin NAD⁺ booster complex, combined with niacinamide and marine and plant extracts, stimulates the endogenous synthesis of NAD⁺ and helps the skin regain energy, resilience, and self-repair capability.
