Eyelashes weak and brittle

I use waterproof and lash primer by Lancôme everyday, while also using a lash curler. Later my lashes have started to come out more on one side more than the other. I try to use Vaseline on my lashes every night to keep them moisturized. Should I take a break from curling my lashes and just use mascara? I feel like curling my lashes is what’s damaging them the most
