SKIN FUEL™ · for skin that looks tired

Looking tired, even after a good night? Tired-looking skin starts in the cell.

A dull, tired look is often a cell-energy question, not a concealer question. SKIN FUEL™ gives your skin 300 mg NR, 200 mg hyaluronic acid and vitamin C*. One capsule a day.

Recognise this?

Three moments your skin looks more tired than you are.

01

The mirror after a short night

Shadows under the eyes, a grey undertone. You look more tired than you feel, and people tell you so.

02

Dull by the afternoon

The morning freshness is gone by three. The skin looks flat, without the glow it used to have.

03

Concealer doing overtime

Every year a little more product to look rested. It covers the surface, the skin underneath stays the same.

The mechanism

Why tired-looking skin is not only about sleep.

1 · Cell energy

A skin cell that renews runs on NAD+.

Skin renews roughly every four weeks, and that work runs on NAD+. NAD+ declines by up to 65% between 30 and 70 (Massudi, 2012). Less cell energy, slower renewal, a skin that looks less fresh.

2 · Hydration

Dehydrated skin reflects less light.

Water in the dermis keeps the skin plump and smooth, so it reflects light evenly. That water is held by hyaluronic acid, and your own production declines with age. A cream works on the outer layer only.

3 · Structure

Collagen keeps the skin firm.

Vitamin C contributes to normal collagen formation for the normal function of the skin.* Collagen is the structure that keeps skin supple and firm.

“I am not a proponent of fillers or artificial results. I believe in supporting the skin from within.”

The formula Dr. Beckers helped shape

Three actives for the skin cell.

01

Nicotinamide riboside (NR), 300 mg.

A direct NAD+ precursor for the energy the skin cell needs to renew itself and keep its barrier in shape.

02

Pure hyaluronic acid, 200 mg.

Pure hyaluronic acid at a high daily oral dose, the molecule your skin uses to hold water in the dermis.

03

Vitamin C, 50 mg.

Vitamin C contributes to normal collagen formation for the normal function of the skin and to the protection of cells from oxidative stress.*

Three actives only count if they arrive. ABSORPTIX® is BRONN's patented formulation logic, developed by pharmacists: every active gets its own uptake route, so they do not compete at the gut wall, plus protection against stomach acid. So the dose on the label becomes a dose in the skin cell.

Month 1
Build-up. Nothing dramatic yet: that is how skin works.
Month 2
First skin cycle done. Users tell us their skin feels calmer.
Month 3
Third cycle: where most users notice the difference.

How to take it

With water, at the same moment every day. Give it three skin cycles, then one pouch a month to keep it.

Good to know

Tired-looking skin, the formula and the 90 days, answered.

Can a supplement help if I simply sleep too little?

Sleep matters and no capsule replaces it. SKIN FUEL™ works on something else: the energy and hydration your skin cells need to renew. That is the part that declines with age, even when you sleep well. Keep your routine, add one capsule a day.

When will I see a difference?

Skin renews in cycles of about four weeks. Most users tell us their skin feels calmer around month 2 and see the difference around month 3. That is why SKIN FUEL™ works best as a monthly routine.

Does SKIN FUEL™ contain collagen?

No, and that is deliberate. Collagen is a large molecule that the gut breaks down before it reaches the skin. SKIN FUEL™ supports your own collagen formation with vitamin C* instead.

Why three months, and why 2+1?

Your skin renews in cycles of about four weeks and only shows a difference after a few of them. The subscription keeps that rhythm going; the 2+1 bundle gives you the same three months in one order, third pouch free.

Who is Dr. Olivier Beckers?

A cranio-maxillofacial (facial) surgeon and BRONN's lead expert. He helped shape the SKIN FUEL™ formula: bio-active forms, meaningful doses, ABSORPTIX® delivery.

Is SKIN FUEL™ officially registered?

Yes. SKIN FUEL™ is NUT-registered with the Belgian Federal Public Service Health and made in Belgium. It is a food supplement, not a replacement for a varied diet. Pregnant or breastfeeding, or taking medication? Check with your doctor or pharmacist first.

The bottom line

Give your skin what it needs. From within, one capsule a day.

SKIN FUEL™ gives your skin cells 300 mg NR, 200 mg pure hyaluronic acid and vitamin C, delivered with ABSORPTIX®. One capsule a day, three skin cycles. *Vitamin C contributes to normal collagen formation for the normal function of the skin and to the protection of cells from oxidative stress (EFSA-authorised health claims).
