In November 2018, Lynch co-founded, along with American actress Daniella Monet, the vegan and cruelty-free make-up and beauty care box Kinder Beauty Box. The subscription box, which started its monthly delivery in January 2019, was intended to "put ethical brands in the spotlight" and "overcome confusing jargon" used by big brands that test on animals. Kinder Beauty Box was conceived after Lynch and Monet discussed the difficulty they had looking for vegan beauty products. The products are curated by them, shipped in sustainable packaging and a portion of the sales goes to animal rights and environmental causes and benefits for vegan rights.
