Ingredient Highlights

From the Eye Doctor:

"I’ve been using castor oil on dry eye patients for years to help soothe their painful symptoms. After seeing many of them develop thicker, longer lashes over time from this treatment, I decided to make it the star ingredient in my serum.”

Dr. Diane Hilal-Campo, Ophthalmologist and Founder of twenty/twenty

OUR PROMISE

Why we say NO to prostaglandin analogues

From our Customers:

★★★★★

I apply on my lids and lashes and I wake up with soothed eyes. My lashes are much more hydrated, and are slowly growing fuller. Love knowing this is safe to use and my eyes feel great! Other lash serums have made my eyes red and irritated. This does not!

★★★★★

I use this serum religiously - twice every day for about 4 weeks now - and my lashes look (and feel!) AMAZING. Seriously, I wish the website could let me post pictures. I've really gotten comments from friends asking if I was using a different mascara/got lash extensions! Highly recommend

Huge Lashes!
