4.9/5 stars from 1,200+ reviews
Longer, fuller lashes — without the sting, the sunken eyes, or the eye-color change.
The 7-Peptide Tear-Match™ Complex feeds your lashes at the exact pH of your tears — real growth, 100% prostaglandin-free.
Longer, fuller lashes in 6–8 weeks
100% prostaglandin-free — your eyes stay yours
Tear-pH 7.0 — no sting, sensitive-eye safe
On clean, dry lashes, morning and night: brush once along the upper lash line, then use the ball tip to dot the roots and any sparse brow areas. Let it dry 30 seconds — then mascara as usual. Consistency is what grows lashes.
Use it every night. If your lashes aren't fuller — or if it stings even once — email us within 60 nights for every penny back. Keep the bottle. The only risk left is doing nothing.
A clear, water-based serum with 7 peptides (incl. Acetyl Tetrapeptide-3, Copper Tripeptide-1), biotin, panthenol and soothing botanicals — buffered to pH 7.0. No prostaglandins. No parabens. The complete ingredient list is printed on every box; we hide nothing.
Week 6 — longer, and my eyes still look like mine
Sensitive eyes + contacts. Zero sting.
Quit GrandeLash after the dark circles. Switched.
Here's what nobody tells you at the counter. The serums that actually grow lashes mostly use a prostaglandin (isopropyl cloprostenate) — borrowed from glaucoma medicine.
It works. It's also linked to darkened lids, hollowed eyes, and — in lighter eyes — permanent color change. One brand paid a $6.25M settlement for not disclosing it was in the bottle.
You shouldn't have to gamble your eyes for longer lashes. So we built the opposite.
Grow lashes the gentle way — no prostaglandin, no sting, no trade-off with your eyes.
It was never your lashes that failed — it was the harsh active. Prostaglandin serums force growth by overstimulating your eye, and the damage rides along. Ours does the opposite: 7 peptides + biotin fortify each lash from the root, in a formula at pH 7.0 — the exact pH of your tears. Real growth, without the sting, the dark lids, or the color change. We call it the 7-Peptide Tear-Match™ Complex.
“Does prostaglandin-free even work?”
You've read it on every thread: “the only ones that work have prostaglandins.” Not anymore. Peptides won't force freakish 2-week overgrowth — they give you visibly longer, fuller lashes in 6–8 weeks, the kind you keep.
One woman who quit the harsh stuff said it best: “I was shocked that it actually works.” Real growth. Eyes that still look like yours.
For the most sensitive eyes
Most serums sit at a pH your eyes hate. Ours is buffered to 7.0 — the exact pH of your tears.
No stinging. No burning. No watering, even on your waterline. Glasses, contacts, post-lash-lift — all fine. Gentle enough for every single night.
Your eyes stay yours
Hazel slowly going brown. Eyes that look hollow and tired. Lids you have to hide with concealer. Those come from prostaglandins — and there are zero in this bottle.
No color change. No darkened lids. Just your own lashes, fuller — and the face you recognize in the mirror. Full ingredient list right on the box.
Week 2: stronger, conditioned lashes — less fallout when you wash your face.
Week 6: visibly longer and fuller — you start skipping mascara.
Week 12: peak fullness — the lashes other people notice.
Not an overnight miracle. A real change you keep — backed by our 60-night guarantee.

Our 60-Night Promise: use it nightly. If your lashes aren't fuller — or it stings even once — email us for every penny back. Keep the bottle. The only risk left is doing nothing.
Yes — just differently. Peptides and biotin grow your lashes over 6–8 weeks instead of forcing them in 2. Real, lasting fullness without the side effects — and a 60-night guarantee if you don't see a difference.
No. It's buffered to pH 7.0 — the same pH as your tears. No burning or redness, even near the waterline or with contacts in.
No. Those effects come from prostaglandins (isopropyl cloprostenate / bimatoprost). This formula is 100% prostaglandin-free, so there's no mechanism for color change or fat loss. The full ingredient list is on the box.
Most people feel stronger, less-shedding lashes by week 2, length by week 6, and peak fullness around week 12. Using it nightly is what makes it work.
Yes. It's water-based and won't weaken extension glue — it's ideal aftercare to rebuild the natural lashes underneath.
Like any lash serum, results are maintained with use. Once your lashes are where you want them, most people drop to a few nights a week to keep them there.
Keep scrolling past serum after serum, half-scared the next one stings or sinks your eyes — and stay where you are.
Or feed your lashes for 8 weeks, risk nothing for 60 nights, and finally get longer, fuller lashes without gambling your eyes.
Your lashes. Your eye color. Your call.
