Lumineux Teeth Whitening Mouthwash Review – A Gentle Whitening Mouthwash That Actually Works

I’ve tried quite a few whitening mouthwashes over the years, and most of them either left my mouth dry, caused sensitivity, or had that harsh alcohol burn I dreaded every morning. So, when I decided to give the Lumineux Teeth Whitening Mouthwash a shot, I honestly wasn’t expecting much — but I’m glad I was wrong.

From the very first use, this mouthwash felt different. There’s no stinging, no harsh aftertaste, and definitely no dreaded sensitivity afterward. I love that it’s fluoride-free, alcohol-free, peroxide-free, and still manages to leave my mouth feeling genuinely clean. The fact that it uses natural ingredients like coconut oil, lemon peel oil, and Dead Sea salt just makes it that much more appealing — it feels like I’m doing something good for my mouth every time I swish.

As a tea lover, I’m always battling mild staining, and while this isn’t an instant whitening miracle, I started noticing subtle brightening within a week or so of regular use — especially when paired with my regular brushing routine. It helps keep my teeth looking clean and polished, and I even got a compliment asking if I had my teeth professionally whitened. That’s a win in my book.

The bottle size is perfect — not too bulky, but enough to last a while — and I don’t mind keeping it on the counter because the design is actually quite nice. The flavor is on the milder side, almost bland to some, but personally I appreciate that it doesn’t overpower my senses or leave a synthetic taste in my mouth. That said, I do wish it had just a hint of mint or something a bit more refreshing — especially if you’re looking for a strong breath-freshening effect. This isn’t that.

One thing to note: shake the bottle really well before using it. Some of the natural ingredients tend to settle, and giving it a good shake makes a noticeable difference in texture and taste.

All in all, this is one of the few mouthwashes I’ve repurchased — and will continue to do so. It’s clean, gentle, and effective. If you’re looking for a more natural way to maintain your oral health and whiten your teeth without harsh ingredients, this is absolutely worth trying.
