The honest part

This will work.
Here's what it won't do.

We'd rather lose a sale than set a wrong expectation.

What KØS does
  • ✓ Rebuilds lashes thinned by extensions
  • ✓ Extends the natural growth phase
  • ✓ Strengthens existing lash fibres
  • ✓ Improves density over 8–12 weeks
  • ✓ Works while you sleep
What KØS doesn't do
  • × Double your length in 7 days
  • × Replace permanently lost follicles
  • × Replace mascara immediately
  • × Produce identical results for everyone
THE TIMELINE

What happens
every week.

Your lashes change more than you think.

WEEK 01

The activation

Peptides absorb into the follicle. You won't see anything yet — but underneath, the growth cycle is already shifting.

WEEK 02

First signs

Lashes feel slightly thicker at the root. Some notice less fallout in their makeup remover. The serum is working.

WEEK 03

The shift

Length becomes visible. The difference is subtle but it's there. People start asking if you're doing something different.

WEEK 04

The result

Fuller. Longer. Yours. This is what 28 days of consistent use looks like. Most customers never stop.

Results compound. The longer you use it, the better it gets.
THE NUMBERS

Science you can
actually see.

Every claim backed by independent testing. These are real numbers from real customers after 28 days.

Tried three serums before this. Nothing came close. Week four the difference was impossible to ignore.

Common questions

  • How long until I see results?

    +
    Most people notice new growth between weeks 3 and 4. A full recovery cycle takes 90 days. We recommend committing to at least 60 days before judging.

  • Can I use it while getting extensions?

    +
    Yes, but it works best when you've stopped. Extensions place mechanical stress on follicles — KØS works against that if they're still being applied.

  • Is it safe for sensitive eyes?

    +
    Yes. Formulated without prostaglandins and synthetic hormones — the two most common irritants in competing serums. Apply to the lash line only, not the waterline.

  • What if it doesn't work for me?

    +
    28-day money back guarantee, no questions asked. If you're not seeing early signs of recovery at 28 days, we refund in full.

  • How do I apply it?

    +
    Once nightly, to the upper lash line. Clean face, no makeup. Let it absorb before applying anything else. That's it.

Start your
recovery.

One drop. Every night. 90 days. That's the whole commitment.
