I put together a list of the top mascaras I have tried over the years and these are the ones I recommend for longer, fuller lashes with little to no clumping. Full disclosure, I loved a Tarte one that was discontinued and will be trying a few new ones from them the next few months!
I recommend all of these but here is my list favorite, to least but still favorite haha:
Maybelline Pumped Up! Colossal
