    The Offer

    The first acne patch
    built for your back.

    Back acne isn't face acne that spread. It lives in skin up to 3× thicker, under sweat and friction — and it needs a different delivery system.

    • WhoFor anyone who plans outfits around their skin.
    • WhatXL hydrocolloid patches sized for backs, shoulders and chest.
    • WhyBecause face patches were never built for body skin.
    • HowPatch tonight. It pulls impurities while you sleep. Peel by morning.

    60-Night Guarantee · Free shipping · Results in 3 nights or your money back

    The Problem

    You were given
    three bad options.

    Tiny face patches

    12mm dots designed for a chin. On a back cluster they cover nothing, and they peel off the moment a shirt touches them.

    Harsh spot treatments

    Benzoyl bleaches your sheets. Salicylic dries a patch of skin you can't see and can't reach twice a day. You quit by day four.

    The $200 derm visit

    Months of waiting for a 9-minute appointment and a prescription your insurance argues about. For most backs, it's a sledgehammer.

    There's a fourth option →

    The System

    The 3-Night
    Clear Back Method.

    Not a product. A protocol. Three nights, three steps, visibly calmer skin.

    1. Night 1

      Draw

      Patch every active spot after your shower. The hydrocolloid core starts pulling fluid and impurities within the hour. You sleep; it works.

    2. Night 2

      Drain

      Peel the proof in the morning — the white dome is everything that used to be under your skin. Re-patch stubborn spots. Swelling visibly down.

    3. Night 3

      Defend

      Patch the flat, healing skin one more night to seal it from sweat and friction — the two things that restart the cycle.

    Start Night 1 Tonight

    But…

    Every doubt,
    handled.

    "Patches don't work on backs"

    Ours survive the wear test.

    We wear-tested against a cotton shirt, a gym session and 8 hours of side-sleeping. The waterproof seal and tapered 0.2mm edges are engineered for friction — 94% of testers woke up with every patch still sealed.

    "I can't reach my back"

    The applicator reaches for you.

    Every pack ships with a fold-flat applicator wand. Load the patch, reach over your shoulder, press for five seconds. One step, no yoga, no roommate required.

    "My acne is hormonal / different"

    Physics doesn't care why.

    Hydrocolloid doesn't treat the cause — it drains the symptom. Whatever triggered the breakout, the fluid inside it responds to the same osmotic pull. That's why it works across skin types, ages and hormones.

    Fast-forward three weeks.

    • The beach trip where you take your shirt off first, not last.
    • The backless dress that's been waiting in your closet with tags on.
    • The gym mirror photo you post instead of crop.
    • Someone touches your shoulder and you don't flinch away.
    That version of you starts tonight

    Last Questions

    Whatever's left, answered.

    How fast will I actually see something?

    Night one: the patch turns opaque as it draws fluid — visible proof by morning. Flatter, calmer skin typically shows by night three. Full marks fading takes longer; that's biology, not the patch.

    What if I genuinely can't reach the spot?

    The included applicator wand adds 30cm of reach — it covers the center-back dead zone. Load, reach, press five seconds, done.

    Will it work on cystic or deep acne?

    Patches drain what has fluid near the surface. Deep cysts need a dermatologist — and we'd rather tell you that here than take your money on the wrong tool.

    Body hair?

    The adhesive grips skin between hairs and peels off without waxing you. Verified by our hairiest testers, who we thank for their service.
