Le Sérum Cils
Lash & Brow Serum — 6g
What's inside: Myristoyl Pentapeptide-17 · Acetyl Tetrapeptide-3 & Red Clover · Panthenol · Amino Acids
Fullness, cultivated.
Tired eyes read as tired, whatever the rest of your face is doing. A peptide serum for lashes and brows — myristoyl pentapeptide-17 and acetyl tetrapeptide-3, no prostaglandins — worn nightly for visibly fuller-looking lashes that are still, honestly, yours. Judge it at eight to twelve weeks, the same as any peptide. The least dramatic product we sell, and the one we would start with.

Before you buy it, the other side.
Every other line on this page is an argument for Le Sérum Cils. This one is not, and it is the part you can check.
What Le Sérum Cils will not do
- Grow lashes the way a prescription does. It conditions; prostaglandin analogues are drugs, and this is not one.
Buy something else if
- You need it this week. Nothing is made until you order it: two to four business days to make, then the lab's weekly dispatch — up to seven business days before it even ships. The first time the lab makes a piece for us it can take up to two weeks longer.
Pair it

Le Mascara contains beeswax, so this pair is not vegan.

Once nightly on clean, dry skin: a single stroke along the upper lash line, like a liner, and along the brows. Keep it out of the eyes.

Understanding Le Sérum Cils
What you're actually buying — and what it changes.
What it is
A peptide serum for lashes and brows — the patient one: fuller-looking lashes and brows over weeks of a ten-second nightly habit.
In your life
Lashes and brows can look thinner over the years — mascara, extensions, over-plucking, time. This is the patient answer: one stroke along the lash line each night, judged over weeks, not days. It's the least dramatic product we sell, and the one we would start with.
The day your usual two coats of mascara look fuller is the day it pays for itself.
What to expect — honestly
Judge it at eight to twelve weeks of nightly use; consistency is the entire mechanism. Skipping nights restarts the clock.
It's for you if
- Your lashes look sparser than they used to
- Brows never looked the same after the thin-brow years
- Extensions left your lashes looking thinner
- You can commit ten seconds a night for two months
The ritual, precisely
Every night, on clean, dry skin
- 01Remove all makeup first — the serum needs bare skin.
- 02One stroke along the upper lash line, like eyeliner.
- 03One pass through sparse areas of the brow. Done.

Questions
Good to know
The things worth knowing before Le Sérum Cils arrives — answered plainly.
Is Le Sérum Cils prostaglandin-free?
Yes. It is a peptide-based formula with no prostaglandin analogues — the ingredient class associated in some products with iris pigmentation change and orbital fat loss. That choice is the whole point of this formula.
How long until I see a difference?
Lashes and brows grow on their own cycle, so expect eight to twelve weeks of nightly use before the difference is clearly visible, and keep going to maintain it.
How do I apply it?
Once nightly on clean, dry skin — a single stroke along the upper lash line like a liner, and along the brows. More product does not accelerate anything.
Can I use it with lash extensions or contacts?
With extensions, yes — apply to the skin at the lash line, not the extensions. With contacts, remove them first and let the serum dry fully before reinserting.
Is Le Sérum Cils cruelty-free — and is it vegan?
Cruelty-free and vegan: nothing in the range is tested on animals, at any stage or by any party, and nothing in Le Sérum Cils is animal-derived, going by what its maker publishes.
How fast does it ship, and can I return it?
Each order is made fresh rather than pulled from a warehouse and ships tracked — 5–14 business days to the US, 5–17 to Canada and 9–28 elsewhere. Standard shipping is free over $75 to the US and Canada, over $120 to the UK, Europe, Australia and New Zealand, and over $150 to Asia and the Middle East. Unopened items can be returned within thirty days; opened beauty items are non-returnable for hygiene reasons.
