Sylk Purple Mouthwash
Most mouthwashes only freshen breath. This one is a purple colour-correcting formula. The violet pigments sit on your teeth and neutralise yellow tones on contact, the same optical science as purple shampoo for blonde hair. You get a visibly brighter smile and fresh breath in one 30-second rinse, with no peroxide and no harsh bleaches.
The colour-correcting effect is visible right after your first rinse, as the purple pigments neutralise surface yellow tones. For the clearest, most consistent results, use one sachet daily as part of your morning routine. Brightness builds and holds with regular use. Individual results vary depending on your starting shade.
No. The purple pigments work optically while you swish, then rinse away cleanly when you spit. They neutralise yellow tones without leaving any purple tint behind. Your teeth look brighter, never coloured.
Yes. The formula is peroxide-free, alcohol-free and SLS-free, so it brightens by optical colour correction rather than chemical bleaching. That makes it gentle enough for sensitive teeth and safe to use alongside crowns, veneers and other dental work. If you have a specific dental condition, check with your dentist first.
Purple colour-correcting pigments neutralise yellow tones for an instantly brighter look. Xylitol supports everyday tooth health. Hyaluronic acid helps keep gums hydrated and comfortable. Peppermint oil and menthol leave breath clean and fresh.
And what's not inside matters just as much: no peroxide, no fluoride, no alcohol, no SLS and no harsh bleaches.
- Tear open one single-use sachet.
- Pour into your mouth and swish for 30 seconds, making sure it reaches every tooth.
- Spit out and smile. No rinsing or brushing needed afterwards.
Pro tip: use it in the morning after brushing for an all-day brighter, fresher finish.

I drink way too much coffee and my teeth had really dulled down. I genuinely did not expect to see anything after one rinse, but the yellow looked softer the very first morning. Three weeks in and my smile is noticeably brighter. It takes 30 seconds and tastes minty and clean. I keep a sachet in my bag now.
I was sceptical that a mouthwash could do anything for whitening. I have years of coffee and red wine to blame for my teeth. Whitening strips always made my teeth ache so I gave up on them. This has zero sensitivity for me and after a couple of weeks people actually commented that my smile looked brighter. Easy win.
I have crowns on my front teeth so I was always nervous about whitening products. This one is gentle and there is no burning or stinging at all. The brightening came on gradually over about a month and my breath stays fresh for ages. Finally something that works without the harshness. So pleased I tried it.
I travel constantly for work and the single sachets are perfect for my wash bag. No bottle leaking everywhere, no mess. I use one every morning before meetings and my teeth look cleaner and brighter than they have in years. The fresh mint is a nice bonus. Cannot fault it.
Tea is my whole personality and it had started to stain my teeth. I love that there is no peroxide or bleach in this. Watching the purple do its thing in the mirror is weirdly satisfying and the difference after rinsing is real. My teeth look brighter and I feel so much more confident smiling in photos now.
I had given up on the colour of my teeth ever changing. Years of coffee and a smoking habit I quit long ago left them looking dull and yellow. I did not believe a mouthwash could help but by week four the difference was obvious. My teeth look brighter and healthier and the whole routine takes seconds. Wish I had found it sooner.
A brighter smile in 30 seconds. Not 2 weeks.
Purple colour-correcting pigments neutralise yellow tones the instant they touch your teeth, the same optical science as purple shampoo. No peroxide, no sensitivity, no waiting around for results. Swish, spit, smile.
How does purple whiten teeth?
Teeth look yellow because of warm tones sitting on the surface. On the colour wheel, purple sits directly opposite yellow, so it cancels those tones out the moment it touches your teeth.
It is the same optical science behind purple shampoo for blonde hair, now made for your smile. No bleach, no peroxide, no sensitivity. Just a visibly brighter smile in one 30-second rinse.
Real results. Real smiles.
