Peptides, not prostaglandins
American serums use a glaucoma-drug ingredient. Peptides condition lashes without the side effects.
Lashes that stop snapping
Biotin and panthenol keep lashes flexible, so length stays put.
A ball tip that reaches the root
Liner brushes paint your eyelid. The ball tip sits in the root — top and bottom row.
Trains them upward
Brush nightly. Lashes dry lifted, not straight out.
Ten seconds a night
Ball tip along the root → Spoolie sweep upward → Sleep
No sting. No wait. No routine.

Why Inalash?
+
🚫 No prostaglandins — none of the lid darkening or hollow under-eyes.
💧 Doesn't sting — balanced to the pH of your tears.
🖌️ Ball tip + spoolie — the ball gets into the root, top and bottom; the spoolie brushes lashes up.
🇰🇷 The Korean approach — peptides and biotin, not a glaucoma drug.
Ingredients
+
Peptides: Palmitoyl Tetrapeptide-7 · Palmitoyl Tripeptide-1 · Acetyl Hexapeptide-8 · Tripeptide-1 · Acetyl Tetrapeptide-5 + 2 more
Conditioners: Biotin · Panthenol · Hyaluronate · Vitamin E · Bisabolol
Free from: prostaglandins, hormones. External use only.
How to use
+
Nightly, on clean dry lashes. Run the ball tip along the top and bottom lash line, then brush up with the spoolie. Brows too. Dry a minute before mascara or extensions.
How it works
+
Lashes run on an 8-week cycle. Thin lashes are usually snapping early, not growing slowly.
American serums use prostaglandin analogs — a glaucoma-drug derivative. They work, and they carry a side-effect list: darkened lids, hollow under-eyes, iris colour change.
Inalash conditions instead. Seven peptides and biotin keep each lash flexible and in the row longer. Nothing on the label needs a warning.
They tried the American one first. Then read the label.

FAQs.
Is this the Korean serum from TikTok?
+
Same approach — peptides, no prostaglandins — under our name, shipped from the US.
Any prostaglandins?
+
None. That ingredient is behind the dark lids and hollow under-eyes. We use seven peptides and biotin.
Will it sting?
+
No — it's balanced to the pH of your tears. If you react, stop; the guarantee covers you.
How fast?
+
Bottom lashes by week 2–3. Thickness before length. Full cycle is 8 weeks.
Extensions, mascara, contacts?
+
Yes to all. Apply, let dry a minute, carry on. Won't lift glue.
Bottom lashes and brows?
+
Yes — the ball tip reaches both. Brows fill in slower.
How long does a tube last?
+
Up to two months, used nightly. One coat is enough.
