Before you ask
That is what the format is for — flatter and wider than a face patch, with an adhesive rated for skin that sweats.
Honestly, you often cannot alone. It is the one part of this we cannot engineer around.
Yes. Sweat and a strap are exactly the conditions it was specced for.
Same material, different cut and a thicker absorbent core. Body breakouts run larger.
Not directly — it works on the next one. For what is already there, The Daylight matters more than you would think.
From men with the same skin

The real problem
The spot fades.
The
mark doesn't.
A breakout on your back lasts a week. The dark mark it leaves — post-inflammatory hyperpigmentation — can stay for six to twelve months, which is most of the year you spend covering it up. And body breakouts sit deeper: picked, squeezed or rubbed raw by a strap, they're the ones that rebuild unevenly and don't leave at all.

Why this exists
Founder video — 9:16
"I'm 27. I've had breakouts since I was 15. Somewhere around 24 I realised I'd stopped caring about the pimples — it was the marks I checked for in every mirror, every photo, every front camera. So I bought patches. They fell off by 3am, every brand, every time, because none of them were built for skin like mine. I got tired of buying products with flowers on the box. So I built the one that was missing."
— Founder, UNMARKED
The technology
Boring science.
Borrowed from hospitals.
Hydrocolloid has been used on wounds in hospitals for decades. The mechanism is unglamorous and proven: seal the site, keep bacteria out, absorb what comes out of it, and let skin close in the moist environment it closes cleanly in. On your back that also means a physical barrier between the breakout and everything rubbing against it — a strap, a shirt, a bench, your own hands.
01
The seal
A closed, moist environment. No bacteria in, no scab, no crust — and nothing your shirt or your hands can reopen.
02
The draw
The core absorbs exudate from the lesion and holds it. That's the white circle you see in the morning.
03
The active
Niacinamide works at the site while the skin settles, calming the inflammation that drives the dark mark.
04
The hold
Extended-wear adhesive specified for sweat and friction. A session, a shirt, a night spent lying on it — same patch.

When it turns opaque, it's working. That white circle is everything the patch pulled out of the breakout — absorbed and binned, instead of picked and spread.
How to use it
Four steps.
No routine.
Shower, then dry
Step 1
Shower, then dry
Bare skin holds best. No body lotion, no oil, no leftover sweat — that's what lifts an edge.
Peel the patch
Step 2
Peel the patch
Lift a patch off the sheet by the edge. Pick the size that covers the whole spot with a margin.
Press to seal
Step 3
Press to seal
Place it over the breakout and press five seconds — edges included. Use a mirror for the middle of your back.
Let it finish
Step 4
Let it finish
Opaque means it worked. Replace if the spot is still active. Repeat until it's flat.
What it is made of
The same mechanism, cut for a shirt
Back and chest skin has larger glands and a thicker surface, so lesions run bigger and last longer — and then spend the day under a shirt, a strap and sweat. Same build, different specification.
The build
-
Medical-grade hydrocolloidThe matrix
Gel-forming agents bonded to a flexible film — the same class of dressing hospitals have used since the 1960s. It absorbs what a lesion weeps and swells into a soft gel, which is the cloudy white disc you see when you peel one off.
-
NiacinamideThe active
Vitamin B3, carried in the matrix so it sits against the site rather than on top of it. It works on the inflammatory signal, and on the handover of pigment from pigment-making cells to the skin around them — the handover that makes a mark visible.
-
Large-format cutThe difference
Sized for the back, shoulders and chest rather than a jawline, because a face-sized patch on a truncal lesion covers part of it and lifts at the edge.
-
Sweat-rated adhesiveThe reason it stays on
Specified for friction and moisture rather than for a dry cheek. It has to survive a shirt, a bag strap, a car seat and a session in the gym.
-
Matte polyurethane filmThe roof
Thin, low-profile and shower-proof, and matte rather than glossy so it does not announce itself under office lighting. A patch you will not wear in daylight only works while you are asleep.
How it works on skin
-
01
It goes on after a shower, on dry skin
Which is also the only time most people can see or reach the site.
-
02
It seals a lesion you cannot supervise
The value on a back is less about the active and more about the fact that nothing is rubbing the site for the next twenty-four hours.
-
03
It holds under friction
A shirt and a strap are exactly the conditions that turn an inflammatory lesion into a longer one. Sealed, they cannot reach it.
-
04
Niacinamide works at the site meanwhile
Same mechanism as the face patch: the inflammatory signal, and pigment handover.
-
05
Off in the morning
One patch, one lesion, one day.
You will need a hand or a mirror for the middle of your back. Everyone does.

With vs without — back / shoulder, before / after
Same breakout. Two endings.
One night.
Not next summer.
Without a patch
The spot clears in a week. The dark mark it leaves is still on your shoulder the next time you take your shirt off.
With the patch on
Sealed from night one. It closes flat — nothing to pick, nothing rubbing it open, nothing to remember it by.
Photography shows real, unretouched skin. Individual results vary with skin type and severity.
What to expect
The timeline,
without the promises.
Opaque means it worked
The white centre is what it absorbed overnight. Peel it. Replace if the spot is still active.
Flat
Most breakouts settle in one to three patches. No scab, no crust, nothing for a strap to catch.
No new entries
Nothing new on the record. Every breakout you sealed healed without adding to it.
Severity and skin type vary. What doesn't: a sealed breakout can't be picked.
Everything else
The rest of it
No, and we won't pretend otherwise. This works on breakouts from the day it arrives, sealing them so new marks never form. The marks already on your back fade on their own timeline, and nothing sold online meaningfully speeds that up. One thing genuinely does slow them down, though: sun. Marks on your shoulders and chest darken with UV exposure, so keep them covered or protected while they fade.
Different skin doing the same thing harder. The back, shoulders and chest carry more oil glands than the face and the skin is thicker, so lesions there tend to be larger and deeper. On top of that they get what your face never does: sweat sitting under a shirt, and constant friction from straps, collars, benches and bedding. That combination has a name in dermatology — acne mechanica — and it's why body breakouts keep coming back in the same places.
Yes — that's what the adhesive is specified for. The one rule is application: put it on clean, dry skin, ideally after your post-session shower rather than onto skin that's about to sweat. Applied dry, it's built to hold through the next session, the shirt and the night.
Same skin, same patch. Shoulders are usually the easiest area to reach and the most exposed to strap friction, so they're often where men notice the difference first. The chest is straightforward. Anywhere the patch can sit flat on bare skin, it works.
Hydrocolloid needs contact with skin to seal. On bare or lightly-haired skin it holds fine. Over dense chest or back hair it won't seal properly, and taking it off won't be pleasant either. Trimmed skin is fine.
Medical-grade hydrocolloid — the same material used in hospital wound dressings — plus niacinamide, a skin-safe adhesive layer and a matte outer film. No fragrance, no alcohol, no essential oils. Full INCI is on the pouch and here: [insert at launch]. Patch-test on your shoulder if you're unsure.
From EU and US warehouses. Tracked delivery, typically 2–5 working days. Plain outer packaging — no branding on the box. [Confirm lanes at launch.]

Early beats late. Every breakout you seal tonight is one that can't leave a mark you'll be covering up all summer.
