What makes it different?
Most lash serums that show fast results use a prostaglandin. It's the same family of ingredient used in glaucoma eye drops, and it's been linked to darker eyelids, red eyes and a hollow look around the eye. We left it out. Instead, a peptide blend conditions the lashes you already have, night after night.
How do I use it?
At night, on clean dry lids, swipe the brush once along your upper lash line, right at the base of the lashes, like eyeliner. Let it dry for 30 seconds. That's it. One swipe per eye is enough.
Is it safe for sensitive eyes?
It's made without prostaglandins, fragrance or parabens. If your eyes are easily irritated, patch test behind your ear first. Take contact lenses out before you apply and wait 15 minutes before putting them back in.
How long until I see a difference?
Lashes grow slowly, so be patient with them. Most women notice softer lashes in the first month and a fuller-looking lash line from week 8. Give it 12 weeks of nightly use for the full result. That's why you get 90 days to try it.
Real Lashes From Women Like You
Your Lashes Have Changed,
It's Not In Your Head
Mascara has nothing left to grab
Gaps at the outer corners
Lashes look lighter, almost invisible
More lashes on the cotton pad
You're not being vain. After 50, lashes really do grow back shorter, thinner and lighter.
Most Lash Serums Make You Choose. Your Lashes Or Your Eyes.
The serums that work fast usually rely on a prostaglandin, an ingredient from glaucoma eye drops. It's been linked to darker lids, red eyes and a hollow look around the eye. The gentle ones often do nothing at all. We made the one in between.
Nothing that can darken lids or change the look of your eyes.
For lashes that grow back shorter and thinner with age.
Mild enough to use daily, for months.

What's Inside, & What Never Is
Every ingredient is here to condition and protect the lashes you already have.
Peptide Complex
Peptides that condition lashes from the base, so they look fuller and stronger over time.
Biotin
A B-vitamin known in hair care for helping lashes and brows look thicker.
Panthenol
Pro-vitamin B5. It softens dry, brittle lashes so they bend instead of snapping.
Hyaluronic Acid
Holds moisture around the lash so it stays flexible between washes.
Never inside: prostaglandins, parabens, fragrance.
The Numbers Behind Thinner Lashes

One Swipe. Ten Seconds. Every Night.
Start with clean, dry lids. Take out contact lenses.
Swipe once along the base of your upper lashes, like eyeliner.
Let it dry for 30 seconds. One swipe per eye is enough.
Repeat every night. Your lashes do the rest while you sleep.
From Night One To Week Twelve
Lashes grow slowly. Here's what to expect when you use it every night.
Your Lashes Feel Softer First
You won't see new length yet, and that's normal. What you'll notice first is softer lashes that feel less dry and don't come off as easily on your cotton pad.
Fewer Lashes On The Pillow
Lashes feel stronger when you take off your makeup. Mascara starts to grab more lashes in one coat.
Your Lash Line Starts Looking Fuller
Look in the mirror without mascara. The gaps at the corners start to look filled in. This is when people start to notice.
Lashes That Look Like Yours Again
Your lashes look fuller and darker from base to tip. Keep using it every night to keep them that way.
