The barrier and pigment modulator. A NAD⁺ precursor with 50 years of scientific data.
Niacinamide (nicotinamide) is the amide form of vitamin B3 and the direct biosynthetic precursor of NAD⁺ and NADP⁺ — the central redox cofactors of cellular metabolism. At 2 – 5% topical concentration it upregulates ceramide and free fatty acid synthesis, blocks melanosome transfer from melanocytes to keratinocytes, and dampens inflammatory cytokine release.
Niacinamide enters the salvage pathway, restoring NAD⁺ levels in mitochondria and powering sirtuin-mediated DNA repair.
Upregulates ceramide, cholesterol, and free fatty acid synthesis in stratum corneum by 30 – 65%, restoring barrier integrity.
Inhibits the keratinocyte PAR-2 receptor that captures pigment from melanocytes, reducing surface pigment by 35 – 68% in 8 – 12 weeks.
Suppresses NF-κB-mediated cytokine release, reducing redness, papule count, and post-procedure flushing.
Supports the barrier, modulates pigment transfer, and refills the NAD⁺ pool — fifty years of scientific data behind it.
Magic, miracles, or anything the dermatology literature does not already quietly confirm.
FoundationalDecades of evidence
5% niacinamide reduced hyperpigmentation and skin yellowness; mechanism confirmed as melanosome transfer inhibition (35 – 68%).
5% niacinamide significantly reduced hyperpigmented spots, red blotchiness, wrinkles, and sallowness over 12 weeks.
2% nicotinamide increased ceramide synthesis by 65%, cholesterol by 32%, and free fatty acids by 56% in human keratinocytes.
They work on different stages. Vitamin C blocks melanin synthesis; niacinamide blocks the transfer of finished melanin to keratinocytes. They are complementary, not competing.
Niacinamide itself does not flush. Flushing comes from nicotinic acid (niacin), a degradation product if niacinamide is hydrolyzed at low pH. Junsui Mirai buffers Mugen at pH 6.8 to prevent this.
