Survived leg day
Gym five days a week and my shoulders finally stay clear. These don't budge, even through cardio.
The oversized hydrocolloid patch built for the skin on your back — where breakouts are bigger, sweatier, and out of reach. Clears without harsh actives.

If you check any of these boxes, it is:
Flattens active breakouts overnight by drawing fluid and oil out of the pore.
Blocks the picking habit — sealed skin heals flat, so marks fade instead of forming.
Shields against friction and sweat from straps, seats, sheets, and gym sessions.
Night 1: On clean, dry skin, seal the whole cluster with one XL patch before bed.
Night 2: Peel off in the morning. Re-patch at night — the patch turns cloudy as it works.
Night 3: Repeat once more. Most breakouts are visibly flatter by morning three.
Sweat-proof and shower-proof once applied. Store the tin somewhere you'll see it nightly.
Size: XL 90mm round — roughly 6× the coverage of a face dot.
Material: Medical-grade hydrocolloid with a waterproof, breathable polyurethane top film and skin-safe acrylic adhesive.
Free from: benzoyl peroxide, salicylic acid, retinoids, fragrance, latex, and animal-derived ingredients.
In the tin: XL patches, placement map, and the 3-Night Method card.
Every Biosage patch is dermatologist tested for skin safety — no harsh actives, no fragrance, no latex. Hydrocolloid is the same gentle wound-care technology skin doctors have trusted for decades.
Gym five days a week and my shoulders finally stay clear. These don't budge, even through cardio.
Gross and satisfying lol. Everything ends up in the patch instead of on my skin. Marks are fading too.
Slept on my back, showered, still on. One patch covered the whole cluster on my shoulder blade.
Sensitive skin and nothing else worked without wrecking it. This did. The photos speak for themselves.
The workhorse. A hospital-grade dressing material that absorbs fluid and oil from the pore into the patch, flattening the bump while keeping the skin underneath protected and moist.
Formulated to grip through sleep, sweat, and showers on thicker body skin — then release in the morning without stinging or stripping.
A thin polyurethane barrier that keeps water and friction out while letting skin breathe — and physically blocks the picking that turns breakouts into marks.
No benzoyl peroxide, no acids, no retinoids. Biosage works mechanically, so there's nothing to dry you out, bleach your sheets, or clash with the rest of your routine.
