Beauty routines aren't what they used to be. Once upon a time, it was cleanse, moisturise, maybe a quick face wipe if you were feeling lazy—I know, the horror! Now? It's serums with unpronounceable ingredients, scalp oils that promise stronger hair and sheet masks for every concern. And honestly, I love it. But it did make me realise there's one part of my routine I'd been neglecting: my teeth. Sure, I brushed twice a day and wrestled with floss, but it never felt like part of the same "beauty" conversation—until now.
TikTok has officially brought oral care into the self-care space, and the timing makes sense. Think about it: we obsess over glowy skin and glossy hair, so why wouldn't we give our smile the same treatment? Enter Coslus's handheld water flosser, the tool currently flooding my FYP and that has just joined my bathroom shelf. At first, I wondered if I really needed another step in my routine, but within a week, I understood the hype. It doesn't just clean (though it definitely does that); it makes the whole process weirdly satisfying. If exfoliating your face is the "ahh" moment of skincare, this is that for your teeth.
Here's what surprised me, though: it doesn’t feel clinical or clunky. Older flossers I've tried were basically countertop appliances that you needed to rearrange your bathroom for, but this one's different. It's cordless, small enough to sit next to my cleanser and actually looks quite sleek. The bigger water tank and longer battery life mean I'm not constantly fussing with it, and yes, I've already packed it in my carry-on once. It feels less like admin and more like a little luxury tucked into my routine.
Like most people, I was previously guilty of brushing and calling it a day, but this has slowly slotted into my daily ritual. At night, after removing makeup and doing my double cleanse, I'll grab the Coslus flosser—fill the tank with warm water, choose a gentler pressure mode, and let it work its magic in under a minute before I layer on serums or moisturiser. It sounds simple, but placing it mid-ritual rather than at the end makes it feel like part of the beauty moment, not an added chore. In the mornings, I sometimes use it after brushing—especially before lipstick days—because it gives everything a cleaner base for makeup.
If you're new to water flossers, my tip is to treat it like you would any skincare tool: start slow to get used to the sensation, and build it into your rhythm. Water flossers use a pulsating stream of water that gently dislodges plaque and food debris from between teeth and along the gumline, reaching spots even a toothbrush can't (think tiny nooks and crevices)—and clinical studies show they can remove up to around 80% of interdental plaque when used properly, all while being kinder on sensitive gums. It's not about overcomplicating your routine—it's about making a step you might've skipped feel quick, easy, and strangely satisfying. And yes, it's waterproof, so I've even taken it into the shower a couple of times—peak multitasking, if you ask me.
And honestly? I can notice the difference. Lipstick applies cleaner, my morning coffee feels less guilty and there's just something about having that fresh-from-the-dentist feeling on a random Tuesday night that makes me want to stick with it. I didn't expect oral care to creep into my beauty routine, but here we are, and I'm not mad about it. I've tried water flossers before, but this new Coslus tool has fully converted me. It's practical, compact, and—dare I say—borderline addictive. There's even an exclusive code which will give you an extra 10% off* the C20 Water Flosser, just use code L2829CBJ. TikTok may have made me buy it, but it's earned its spot on my bathroom shelf all on its own.
