What Is 5-Deazaflavin? The NAD+ Skincare Ingredient Changing Anti-Aging Science

5-Deazaflavin is a flavin analog studied as an NAD+ pathway support. In plain terms: cells need energy to repair. NAD+ is part of that energy accounting. Skin that has taken sun, wind, and long shifts is asking for both a repair signal and enough cellular energy to use it.

Immortal Toner is where we put it — in an alcohol-free rose hydrosol, stacked with GHK-Cu copper peptide. GHK-Cu is the repair signal (collagen and elastin support). 5-Deazaflavin is the energy-side of the stack. That combination is what we filed: US provisional patent #63/945,767 (December 20, 2025).

This is not a pill, not an IV, not a miracle. It is a topical, handcrafted in Wyoming.

How it fits the line

  • Immortal Toner — GHK-Cu + 5-Deazaflavin. The stack.
  • Sól Radiance — GHK-Cu in rose hydrosol, no 5-Deazaflavin. Lighter mist.
  • Sól Skin Serum — oil-based peptides (Synthe'6, Juveleven, Teprenone). Use after toner.
