The Curl Effect: The Science Behind Eyelashes That Curl Naturally

The Better Way to Curl Your Lashes: With Physician-Developed Science

Until now, there were only a couple ways to get lifted lashes, and both have their drawbacks. Lash curlers work by creating a temporary bend in the eyelashes using mechanical pressure, and the results only last a few hours. Lash lifts can last much longer — around six weeks — but require a visit to a professional, who will curl your lashes around a mold and apply a chemical perm solution followed by a setting solution to your eyelash hairs. While both of these methods are safe when done correctly, they can cause stress to your lashes over time. If you’re prone to brittle lashes or lash breakage, or just want to ensure your lashes remain strong and healthy, there’s a better way to achieve a lasting curl.

Enter our physician-developed RevitaLash® Advanced lash serums. Each of our lash conditioners (RevitaLash® Advanced, RevitaLash® Advanced Sensitive, and RevitaLash® Advanced Pro) is formulated with patented technology for The Curl Effect®. This technology, which you won’t find in any other lash serum on the market, delivers nutrients directly to lashes to help them look healthier and feel stronger. It also can boost your eyelashes’ natural lift and curl.

Real users have seen incredible results with our Curl Effect technology. In our 16-week tests, our five users saw an increase in their natural lash curl between 31 and 59 degrees!* Lashes transformed from straight and downturned to luxuriously lifted and eye-opening. And all it took was a swipe a day of our RevitaLash® Advanced lash serum.

Even better, each of our lash serums is ophthalmologist and dermatologist-reviewed, clinically tested, hypoallergenic, non-irritating, and free of oil, parabens, phthalates, fragrance, and gluten. Plus, they’re vegan-friendly and cruelty-free. Finally, a way to get a natural curl that’s actually good for your lashes!

Curling Your Lashes: Do’s and Don’ts

No matter which method you use to curl your lashes, familiarize yourself with these tips to keep your eyelashes looking healthy and beautiful:

DO use a lash curler designed to curl without crimping or damaging your lashes. Replace the pads of the curler every two months.

DON’T curl your lashes after applying mascara; this can cause eyelashes to stick to the curler and pull out. Only curl clean, dry lashes.

DO use a lash conditioner daily to care for your lashes and keep them flexible, shiny, and healthy—especially if you get lash lifts or extensions.

DON’T use any product on your eyelashes in the first 24 hours after a lash lift, as this can negatively affect your lashes’ curl.

DO use a blow dryer to gently heat your lash curler before using (not too hot!) if you want to create a longer-lasting curl.

DON’T try lash lifts or other chemical lash services at home. Always go to a trained professional you trust.

DO apply lash conditioner directly to your eyelashes to maximize the benefits (not to the skin of your eyelid).
