The cosmetics company Tarte claims its new mascara, 4 Day Stay Lash Stain lasts for 4 days with a single application. Does it? We test it to find out.

(PS: I still haven’t got the hang of that mascara brush!)

If you’d like to try it yourself, Tarte 4 Day Stay Lash Stain is available at Sephora for around $18.
