About Lark

When was Lark founded?

Lark was founded in 2021.

How did Lark come into being?

When Lark's cofounders were having random small talk about toothpaste ingredients one night, they had no idea where it would lead them (this may or may not have been after a drunken binge). What began as banter and laughter over how to pronounce diethanolamine and carrageenan evolved into a much larger mission to create non-toxic oral care.

Who founded Lark?

Our co-founders Josh and Valery have always been especially passionate about two things: solving problems and the environment. After examining the wasteful packaging and harmful chemicals that went into making traditional toothpaste and mouthwash they took matters into their own hands. The oral care industry was due for an upgrade. That's when they set out to build Lark, a new way to brush for a new generation- utilizing clean ingredients only and sustainable packaging to ensure the cleanest brushing experience for both your mouth and mother nature.

Where are your products manufactured?

Our hero products -mouthwash and toothpaste tablets are manufactured in the U.K according to strict GMP standards.
