System Verdict
Overengineered, highly capable anti-aging essence with excellent support ingredients — but the headline NAD+ story is diluted by likely trace-level placement and no proof of clinically meaningful delivery. The formula scores well because it starts with a strong hydration and barrier base, includes niacinamide at a meaningful position, and adds adenosine, cholesterol, panthenol, beta-glucan, multiple peptides, and antioxidants; however, the truly flashy actives like NAD+, glutathione, resveratrol, astaxanthin, and many peptides sit deep in the INCI, so they are probably present at low levels and cannot be credited as primary drivers of efficacy.
