The science

DORUK is built on mechanisms you can read about and results you can measure. Every ingredient earns its place through published evidence — not marketing. 12 active compounds, each clinically dosed. Zero proprietary blends or undisclosed amounts. 100% of batches third-party lab verified.

Three pathways of aging. One daily intervention.

01 — Cellular energy. NAD+ precursors restore the fuel your cells lose with age, supporting DNA repair and metabolic resilience from the inside.

02 — Oxidative load. Targeted antioxidants neutralise the free radicals that accelerate visible aging in skin and tissue alike.

03 — Barrier & collagen. Peptides and bakuchiol signal for collagen and reinforce the skin barrier overnight, where recovery actually happens.

Full transparency, down to the milligram

• NMN — 500 mg. Nicotinamide mononucleotide, a direct NAD+ precursor studied for its role in mitochondrial function and cellular repair.
• Trans-resveratrol — 150 mg. A polyphenol that supports sirtuin activity and partners with NMN to extend its longevity pathway.
• Bakuchiol — 1%. A plant-derived retinol alternative shown to improve firmness and fine lines without the irritation of retinoids.
• Matrixyl peptides — 4%. A signal-peptide complex that prompts collagen synthesis and visibly smooths skin over weeks of nightly use.

Tested every batch. Published every time.

Each production run is screened by an independent ISO-accredited lab for potency, purity, and contaminants — potency to label claim, heavy metals and contaminants, microbial screening, and a certificate of analysis per batch. The certificate ships with your order and lives online.
