Second use and I could see it

"I'd stopped believing anything worked on this bit of my face. Second Sunday in, I could see it. Not dramatic, just less tired looking. I've reordered twice."

I cancelled the filler

"I had a tear-trough consultation booked and I cancelled it. I'm giving this six months first. Never thought I'd write that about something you peel off your face."

Denise M. Bristol Verified buyer

Bare-faced for the first time in years

"I did the school run without anything on my face and didn't think about it once. I hadn't realised how much I'd been hiding until I stopped."

You can wear it round the house

"I made tea, emptied the dishwasher, answered emails. By the time I sat down it had gone clear. Forty-five minutes that cost me nothing."

What your skin does, week by week

  1. 1 Mask 1 · Week 1

    "Wait, it actually did something."

    Your first wear tells you this was not another waste of money. Acetyl Hexapeptide-8, collagen and hyaluronic acid held against skin that has been quietly starved for years. You wake up smoother, plumper and less tired looking, and the fine lines sit softer in the morning light.

  2. 2 Weeks 2 to 4

    "This is becoming my thing."

    Once a week, the change stops being an event and becomes your baseline. The area holds its hydration longer between masks and the corners read softer. By week three a lot of women go up to three wears a week when there is a run of late nights or something coming up. It is a hydration window, not an active you can overdo.

  3. 3 Day 30 · The turning point

    "Someone noticed."

    This is the milestone that changes everything. After a month of weekly wears the change crosses the line from you seeing it to someone else seeing it. A partner, a colleague, your daughter. It is the moment this stops being a trial and becomes a routine.

  4. 4 Day 60 · Month 2

    "I can photograph the difference."

    Two months in, the softening around the outer corner is consistent enough to catch in a before and after. Same mirror, same light, same time of day. The area feels firmer to the touch, and you stop checking it in every reflection you pass.

  5. 5 Day 90 · Month 3

    "Okay, what have you been doing?"

    By the third month the question stops being "have you done something" and becomes "what is it". And it is coming from people who do not know you well, not just family. Most women describe it as finally looking like themselves from a few years ago.

  6. 6 Month 6 and beyond

    "This is just my skin now."

    Six months in and the mask is not something you buy, it is a standard you keep. You know exactly what happens if you stop, because the area goes back within a fortnight. It stopped being a cost a long time ago. It is the upkeep on the version of yourself you got back.

The change lives in the rhythm.

One box is five wears. Weekly, that lands you on day 30, which is exactly where other people start noticing. Start this week and you are there in five.

Our story

Elin Harper, founder of Kosuna

Elin Harper

Founder of Kosuna

At 47 the first thing to go was the skin around my eyes. Not lines exactly. Texture. Crepey on the lid, papery at the outer corner, and by four in the afternoon I looked like I had not slept in a week.

I did what everyone does. Eye creams first, some of them ninety pounds a jar. They sit on the skin for about sixty seconds and then the air takes them back. Then under-eye patches, which are two crescents covering the one part of my eye that was not the problem. They never reach the lid or the outer corner, and that is where crepiness actually starts.

So I went and got quoted for tear-trough filler. Four hundred and fifty pounds, needles, and a practitioner who told me straight that it would not do anything for the texture anyway.

That is the gap. There is nothing between a cream that cannot stay on long enough to work and a clinic that costs four hundred pounds and puts a needle in your face. So I went to Korea and had the rung in between built.

Kosuna is one continuous mask per eye. It covers the lid, the under-eye and the outer corner in a single piece, and it holds a full dose of Acetyl Hexapeptide-8, collagen and hyaluronic acid against the skin for forty minutes. Not sixty seconds. Not two crescents. Forty minutes, all three zones, once a week.

    Proper active, not a word

    I'm sceptical of the word collagen on a box. No sting, no tightness. Peptides are the tolerable end of actives and that held true for me. Well made, clearly.

    Korean formulation

    I've had good results with Korean skincare before so that was a point in its favour.

    52 and she thought I was younger than her

    Easy to deal with the Kosuna team when I had questions, but the main thing is this actually does what it says. I noticed a difference the first time. The second time was a proper difference and my husband said something without me prompting him. What sold me is the shape of them. Most eye patches are just an oval that sits on the cheekbone and does nothing where you actually need it. These are cut in a C, so one piece covers the lid, goes up over the brow bone and comes back down round the outer corner. The whole eye, not a bit of it. We were at a gig and someone mentioned one of the bands was more for the fifty-year-olds. When I said I was 52 the woman I was talking to went quiet — she was 46 and thought I was younger than her. She asked what I was doing. I said Kosuna. Thank you for the confidence boost.

    It's not vanity, it's accuracy

    I don't want to look 30. I want to look like I feel, which is fine.

    The peptide has somewhere to go

    I stopped believing in eye cream about five years ago. Acetyl hexapeptide-8 is a real peptide with real work behind it, not a marketing word on a carton. Give me the mechanism and I'll try it.
