I put it on in the car before work. Five minutes later my bags looked half the size. My coworker asked if I'd had a facial.

Peptides and hyaluronic acid are what I reach for with tired, puffy under-eyes. Kosen puts them in a gel that sets fast and sits well under makeup, so patients actually keep using it.

This is the first thing that has made my under-eyes look smoother. I look awake even when I barely slept.
Maria G. · United States
Didn't expect it to work this fast. The de-puffing is real, and it doesn't leave that white film other gels do.
Priya S. · United Kingdom
At 56 I'd given up on eye creams. This one sets clear and my concealer doesn't crease anymore.
Linda P. · Canada
I filmed one eye with it and one without. The difference made my sister order two tubes.

Light, clear, no smell. It's become the first step of my morning routine.

Ordered the 2-pack after seeing my mom use it. Zero white film, which is why I gave up on other gels.

Firmer-looking eyes without injectables
Instant-firming eye gels went viral after makeup artists started using them backstage to smooth under-eyes in minutes.
Kosen pairs that fast-setting effect with a Korean peptide complex, so you get the instant lift and daily care in one step.
No needles, no downtime, no clinic price tag.
What it is
A clear gel that forms a thin, flexible film as it dries, visibly tightening and smoothing the under-eye area.
Why it works so fast
The film tightens as water evaporates, so the smoothing effect shows in 3–5 minutes. Peptides and hyaluronic acid care for the skin underneath.
In-clinic treatments vs. Kosen
Clinic treatments can cost hundreds per session. Kosen gives you a smoother look every morning, at home, for less than a coffee a week.
Is it safe?
Yes. It's fragrance-free and dermatologist tested for use around the eyes. Keep it out of the eyes themselves.

Reasons why everyone's obsessed with this gel
-
Smooth eyes in 5 minutes
With Kosen you see the lift in about five minutes: smoother, tighter under-eyes that look like you slept all night (even if you didn't).
-
Deep peptide care
A Korean five-peptide complex and hyaluronic acid sink in while the film sets, hydrating and firming the look of delicate under-eye skin.
-
Skip the 7-step routine
One swipe replaces eye cream, primer and color corrector, so concealer sits smoothly instead of settling into lines.
-
Clinic look, not clinic price
Get a rested, camera-ready look at home for a fraction of a facial. No needles, no filters, no appointments.
-
Safe for sensitive eyes
Fragrance-free and dermatologist tested around the eye area, so it calms while it works, even on sensitive skin.

Instant results I didn't expect

Better than my facial
Honestly gave me better results than my last $150 facial. My under-eyes looked firmer and I felt way more confident.
Emma T. · UKVerified buyer
Finally, no white film
I've tried every tightening gel out there. This is the first one that dries clear and doesn't pill under concealer.

FAQ
What does Kosen do?
Kosen Peptide Eye Firming Gel is a fast-setting gel for the look of puffiness, bags and fine lines. A thin layer tightens as it dries, so under-eyes look smoother and firmer in about five minutes.
How do I use it?
On clean, dry skin, swipe a thin layer under each eye. Keep your face still for 3–5 minutes while it sets. Then wear it alone or put makeup on top.
Will it leave a white film?
No. Kosen is made to dry clear. If you see any residue, you've used too much. A rice-grain amount covers both eyes.
Can I wear it under makeup?
Yes. Let it set fully, then apply concealer or foundation with a light patting motion.
Is it safe for sensitive skin?
Kosen is fragrance-free and dermatologist tested around the eye area. As with any new product, patch test first.
How long does one tube last?
A 15 mL tube lasts about 6–8 weeks of daily use. That's why most people choose the 2-tube bundle.
Where is it made?
Kosen is made in Korea and ships from our US warehouse.
What if it doesn't work for me?
You have 30 days to try it. If you don't love the results, contact us for a full refund.
