Key ingredients + -

Hydrogen peroxide: but make it food-grade! The hero behind our safe, low-sensitivity whitening tool. The level of Hydrogen Peroxide is safe for all.

Flavour: we use natural Spearmint and Coconut Flavours to give our Whitening Pen a fresh aftertaste.

Xylitol: this corn-derived sweetener has anti-bacterial properties, is non-cariogenic and doesn’t ferment in your mouth to feed tooth decaying bacteria. Importantly, this has the effect of reducing plaque formation and inhibiting enamel demineralisation.

How to Use + -

Twist the bottom of the pen until liquid rises to the tip (about 15 cranks on your first go). Using the brush, apply a small amount of liquid to your teeth, avoiding your tongue and gums. Leave for 10 minutes, then rinse with water. Use once a day, preferably at night, after brushing your teeth. Do not eat or drink for 30 minutes after use.

It's like a little secret weapon in my purse. My smile is noticeably brighter, and I can keep enjoying my daily latte guilt-free. It's the real deal, ladies!"

I think it is time for a shake up in the oral care world. For a long time, we have seen the same products in the same flavours, so with Gem I am loving that we have something new, something that is really safe, beautiful and chic but is also backed by science.

      "The thing about Gem that I like is that they have replenished those elements of their toothpaste with hydroxyapatite, sodium bicarbonate and other elements that give us that whiter smile and protected enamel which a lot of other natural toothpastes tend to miss the mark on.”
