PEROXIDE-FREE ✳︎

NO STING
No mystery blend. Here's every ingredient in FLASH and the job it does.
The whitening active. It lifts surface stains through oxidation — the result you want from peroxide, without the free radicals that set off sensitivity.
The same mineral your enamel is built from. It settles into microscopic surface wear while you whiten, so teeth end up smoother — not more sensitive.
A phosphate that helps loosen surface stains and makes it harder for new ones to stick — so the brightening lasts longer.
The strip itself. A plant-based film that melts in about 10 minutes, so there's nothing to peel off and nothing to rinse.
NO STING ✳︎
upper + lower, one sachet ✳︎the product is new — the science behind it isn't
Published research comparing PAP-based formulas with hydrogen peroxide reports visible shade improvement without the enamel-surface etching or sensitivity spikes peroxide is known for.
Systematic review — Dentistry Journal, 2025 ↗︎Decades of dental literature show hydroxyapatite binds to the tooth and remineralises early wear — unsurprising, since it's the same mineral enamel is made of.
Hydroxyapatite in Oral Care Products — review ↗︎Statements refer to published research on the individual actives, not clinical trials of this product.

Eindelijk whitening waar ik niet tegenop zie. Geen gedoe en na een paar dagen begon ik zelf verschil te zien.
I drink way too much coffee to pretend otherwise. FLASH has become my little reset. Easy, quick, and my teeth just look fresher.
I wasn’t looking for Hollywood white. I just wanted my teeth to look a bit brighter in photos. This is exactly that.
Ich wollte keine unnatürlich weißen Zähne. Einfach etwas heller und gepflegter. Genau das ist passiert.
Ik wilde vooral niet van die onnatuurlijk witte tanden. Gewoon mijn eigen tanden, maar dan wat helderder. Precies goed.
Je bois beaucoup trop de café pour avoir les dents parfaitement blanches. FLASH leur donne juste ce petit coup d’éclat que je cherchais.
Kaffee aufgeben? Keine Chance. FLASH ist die bessere Lösung. Nach ein paar Tagen sahen meine Zähne einfach frischer aus.
Koffie ga ik echt niet opgeven. Gelukkig hoeft dat ook niet. Na een week FLASH zagen mijn tanden er gewoon een stuk frisser uit.
No quería unos dientes blancos de anuncio. Solo que los míos se vieran un poco más luminosos. Justo lo que buscaba.
Non volevo denti bianchissimi e finti. Solo il mio sorriso, un po’ più luminoso. FLASH ha fatto esattamente questo.
Super unkompliziert. Aufkleben, kurz vergessen, fertig. Nach etwa einer Woche habe ich den Unterschied auf Fotos gesehen.
Two espressos a day and my teeth had the receipts. One week of FLASH and my sister asked if I'd been to the dentist. No sting, no drama — just peel, press, done
first strip? ✳︎everything people ask before their first strip
No — that's the point of this formula. Classic peroxide whitening pushes oxygen through the enamel, which is what can trigger that familiar zing. FLASH takes a different route: PAP oxidises stains without releasing free radicals inside the tooth, while hydroxyapatite helps smooth and protect the enamel as you whiten.
Most people notice a difference within the first few sessions. The full course is one pack of 28 strips (14 sessions, two strips each) — twice a day it takes 7 days, once a day 14, whichever suits you. That’s where the real shift happens.
Yes. PAP doesn’t demineralise enamel the way peroxide can, and the hydroxyapatite in every strip is the same mineral your enamel is made of — it fills microscopic surface wear as you whiten.
You don’t have to change your life. Rinse or brush before a session, and try not to re-stain in the first half hour after. That’s it.
Months — depending on your habits. Coffee, wine and smoking re-stain faster; an occasional top-up strip keeps you where you want to be.
