Chances are that you’ve probably pondered the following question at one point or another: “Does my makeup primer actually work?” Without a side-by-side photo documenting your results and zero time to commit that sort of dedication, it’s hard to tell. The question has manifested for us after mornings spent diligently priming our lashes with wild abandon in hopes that our lashes would extend upwards as far as our eyebrows like magic. Clearly, we have yet to experience this sort of beauty bliss. Will eyelash primer really play a role in helping us get there?The verdict, according to our friend and makeup artist Andrew Velazquez_ is that the results depend on the mascara formula you choose. "The objective of a mascara primer is to typically provide real lash hairs with keratin or to work with mascara to avoid clumping, separate the lashes, increase volume and lengthen,” Velazquez explains. “Some might even make mascara waterproof depending on the formula."How to Apply Your Mascara Primer Correctly “Usually, with the brush that it’s packaged with is best because it’s already meant to work synergistically with the formula,” he says. “I would recommend you lift your chin up, use a compact to look down so the lashes stick straight out, lift with one hand to help get more maximization of the lash and as you’re applying the product, round brush into the lash to help curl to help curl and separate the hair.” In conclusion, mascara primers really do work, but in just a different way than you might have thought.
