If you ever used a spoolie you nabbed from Sephora to swipe mascara onto your lashes, you've seen how your lashes glistened and separated easily. Often causing lashes to clump together, it's rare that putting mascara onto bare eyelashes will give you the same effect. Eyelash primer helps to stop mascara from clumping, lengthens and volumizes lashes, and softens them.
A mixture of mineral oils and natural waxes, Vaseline also conditions and softens, keeping moisture trapped. Petroleum jelly is also quite gentle, so you most likely won't experience any rashes or allergic reactions if applied to your lashes. Although it probably won't make your mascara last longer, it can be a great primer for softening and separating lashes before you put on mascara.
Some people on TikTok even use the product to emulate the effect of a lash lift. Apply a bit of Vaseline onto the lashes, then go in with your lash curler. Using a spoolie, brush your lashes upward and hold the curler for a bit. While it definitely won't last nearly as long as a proper lift, they still help to give your lashes a boost.
