The Science of Beauty: The Crazy Way Lash Growth Products Really Work
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)!
If Your Lashes Are Damaged, Look For Peptides
Eyelashes, just like hair, are made up of protein. In fact, they're over 90% protein. This is where amino acids come into play. Not only are amino acids the building blocks of protein (and thus, your eyelashes), they also nourish and repair damage. This is why they're a main ingredient in so many lash-enhancement formulas. But keep an eye out: Many brands include amino acids in their formulas that go by a different name: peptides. (A peptide is simply a chain of amino acids.) According to Kim, peptides "nourish, condition, and strengthen frail and brittle lashes."
Our pick for a peptide-packed formula? Try Revitalash's VLumine ($111), a lash-enhancing serum infused with time-release peptides that improved lashes' "strength, shine, and elasticity."
Collagen Plumps Hair, Just Like It Plumps Skin
Speaking of protein, collagen is the most abundant protein in the human body. We know all about its skin and hair benefits (it does everything from repairing damaged strands to plumping sagging skin and wrinkles), but did you know it's also an amazingly transformative ingredient in many lash growth formulas?
To get the benefits for cheap, L'Oréal's Extra Volume Collagen Mascara ($5) promises up to twelve times more volume added to your lashes.
Lash Serum Restores the Moisture Your Mascara Took Away
Moisture is the key to healthy lashes, just like it's the key to healthy skin. Without it, eyelashes are prone to breakage (which is exactly what you don't want when trying to channel your inner no-makeup confidence).
Unfortunately, the main culprit of moisture loss could be your own trusty tube of mascara. According to Kim, it can be incredibly drying and weakening. That's why she suggests using serum-infused formulas. The good-for-lash ingredients will counteract and repair damage done by other formulas. LashFood's Phyto-Medic enhancer is natural, vegan, and gluten-free, and its powerful herbal extracts will enhance lashes in as little as four weeks. It's even gentle enough to use while wearing lash extensions.
More Lash Growth Tips
Aside from the recommended serum treatments, Kim had a few other tips to achieving those glamorous, arch-grazing lashes of Hollywood dreams. "Some alternatives to help create the appearance of fuller, longer looking lashes may include taking biotin and eating a healthy diet rich in B vitamins can help promote the health of lashes," she says. "Switching to natural eye makeup products can help lash health as well." We love Fusion's Hair, Skin, and Nails ($28) for an easy boost of biotin.
