Frequently asked questions

How fast will I see results?
Most people notice a visibly brighter smile in as little as 7 days with the whitening strips, using them just 30 minutes a day. Results vary with your starting shade and habits like coffee, tea and wine.
Will it hurt or make my teeth sensitive?
Our strips are peroxide-free and designed to whiten with dramatically less of the zing and sensitivity that traditional strips cause. The toothpaste is a gentle, low-abrasion formula that won't strip your enamel.
Is LumySmile safe for enamel and gums?
Yes. Everything we make is enamel-safe and gum-friendly — it brightens without damaging or weakening your teeth. If you have specific dental concerns, we always recommend checking with your dentist first.
Are your products natural and eco-friendly?
They're built around natural ingredients like activated charcoal and coconut oil, free from artificial dyes and harsh additives. Our bamboo toothbrushes use a biodegradable handle and BPA-free bristles.
How long does whitening last?
With regular maintenance — brushing with the charcoal toothpaste and occasional strip touch-ups — your brighter smile can last for months. Diet plays a big role, so lighter on the coffee and red wine helps.
Where do you ship and how long does it take?
