The Science of Beauty: The Crazy Way Lash Growth Products Really Work

Kaitlyn McLintock


In our new series, The Science of Beauty, we're going to do a bit more research into the making of a great beauty product. While we've talked about the textures, scents, and efficacy of our favourite formulas in our Reviewed series, this one is meant to feed the other side of the brain—the side we perhaps haven't tapped into since chemistry class. We'll talk science, experiments, and the ingredients that make each product work with experts in each specific field. Then we'll check back in with our favourite hair and makeup artists to get a breakdown on how to best use the products once they're out of the lab and back in our bathrooms.

There’s just something about full, fluttery lashes that instantly awakens the face. My mascara is as instrumental to a productive morning as my daily cups (yes, that’s plural) of coffee. Lashes are the single most important part of my makeup routine, and Faith Kim, Creative Director and Co-Founder of LashFood, agrees. "Big, beautiful lashes will act like a mini eyelift and widen eyes to make lids look less heavy and more awake," she says.

But then I got to thinking: Why rely solely on mascara when there are lash treatments that can strengthen and enhance my natural set? I dream of a day when I can confidently forgo my favourite inky black cosmetic. But, more importantly, how do these formulas actually deliver the results they claim? My fellow beauty geeks will understand: I just had to learn the details, so I got Kim to tell me everything. Keep reading to learn exactly how lash-growth formulas work (and which ones we love to use)!
