The science behind BRONN, ABSORPTIX®.
Most skin supplements fail for one reason: the body never absorbs them. ABSORPTIX® is a patented formulation logic, developed by pharmacists and physicians, built to get NAD+ (NR), hyaluronic acid and Vitamin C to the cell, where they actually work.

"The best results always come from a healthy cellular foundation. With SKIN FUEL™, ABSORPTIX® is what makes the difference: it ensures the NAD+ precursor, hyaluronic acid and Vitamin C actually reach the skin cell, instead of being lost on the way. That is where real, lasting skin health is built."

Every active, the dose, and why it is there.
| Ingredient | Per daily capsule | What the science says |
|---|---|---|
| Nicotinamide Riboside (NR) | 300 mg | A premium NAD+ precursor that helps maintain healthy NAD+ levels to fuel cellular repair and skin vitality. |
| Pure Hyaluronic Acid | 200 mg | A high-dose structural component supporting skin hydration and elasticity from within. |
| Vitamin C | 50 mg | Contributes to normal collagen formation for the normal function of the skin, and protects cells from oxidative stress.* |

How we get the nutrients to your cells.
Smart formulation.
Physician-led formulas with zero fillers. Each active is chosen and dosed for a specific, evidence-based role in skin health, nothing for show.
Step 1 · formulationBio-active ingredients.
Instead of raw compounds, ABSORPTIX® uses direct active metabolites and catalysts the body recognises, so nutrients bypass complex internal conversion steps.
Step 2 · bio-activesMaximum synergy.
NR, hyaluronic acid and Vitamin C are combined to work together rather than compete for absorption. Each ingredient gets its own uptake route, so there is no traffic jam at the gut wall.
Step 3 · synergyOptimised environment.
Internal priming creates the conditions for seamless uptake, so the actives reach the deeper layers of the dermis. It is not about how much you take, it is about how much your skin cells can actually use.
Step 4 · uptakeReal people, real routines.

The science, answered.
What exactly is ABSORPTIX®?
ABSORPTIX® is BRONN's patented formulation logic, developed by pharmacists and physicians to overcome the metabolic barriers that stop most supplements from working. Instead of just filling a capsule, it uses direct bio-active metabolites and catalysts the body recognises and absorbs immediately.
Why does absorption matter more than dose?
A high number of milligrams on a label means little if the body breaks the compound down before it reaches the skin. ABSORPTIX® optimises the absorption environment so the NR, hyaluronic acid and Vitamin C reach the deeper layers. It is about how much your cells can actually use.
Is it clinically evaluated?
Yes. An independent skin therapist (Instituut Merel) documented one daily SKIN FUEL™ capsule on reactive skin across 6 and 12 weeks, with optimal results after 12 weeks. SKIN FUEL™ is also NUT-registered with the Belgian FPS and reviewed by an 8-member expert panel.
What is the 2+1 bundle?
Three months of SKIN FUEL™ for the price of two: €118,80 instead of €178,20, so your first month is free and you save €59,40. Prefer monthly? Subscribe and save 15% (€50,49/mo) with free shipping.
It is not how much you take. It is how much your cells receive.
