Is This For You?

If you check any of these boxes, it is:

  • You get breakouts on your back, shoulders, chest, buttocks — or anywhere else on your body
  • Your spots show up in clusters, not one at a time
  • Body washes don't work for you
  • Harsh acne washes leave your skin dry or stinging
  • Old breakouts leave marks that stick around
Benefits

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.

How To Use — The 3-Night Method

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.

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.

"For body breakouts, occlusive hydrocolloid is one of the smartest first moves — it protects the lesion, absorbs drainage, and stops the picking that causes most of the scarring I see." — Consulting dermatologist, Biosage product review panel

Key Ingredients:

◍ Medical-Grade HydrocolloidTargets: Active breakouts, drainage

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.

◎ Skin-Safe Acrylic AdhesiveTargets: All-night hold on body skin

Formulated to grip through sleep, sweat, and showers on thicker body skin — then release in the morning without stinging or stripping.

◉ Waterproof Breathable Top FilmTargets: Sweat, friction, picking

A thin polyurethane barrier that keeps water and friction out while letting skin breathe — and physically blocks the picking that turns breakouts into marks.

○ Zero Actives — On PurposeTargets: Sensitive, easily-stripped skin

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.
