What Our Tape Is Made From (And Why It Matters)

Most mouth tapes can't tell you what their adhesive is made from. We can — down to the supplier, the certification, and the chemistry.

The Problem

The problem nobody talks about

🏷️

Most mouth tapes are made with generic adhesives originally designed for packaging, athletics, or industrial use — not for the delicate skin around your lips.

🤐

Many brands can't (or won't) disclose what their adhesive is made from, where it's sourced, or whether it's been independently tested for skin safety.

⏰

When something sits on your face for 7-8 hours every night, "it's probably fine" isn't good enough. You deserve to know exactly what you're putting on your skin.

Sleep Karma was created because most mouth tapes couldn't clearly prove their adhesive safety. We decided to build one that could.
The Adhesive

Our adhesive: sourced, tested, certified

Our adhesive is manufactured by Henkel — a German chemical company with over 140 years of materials science expertise. It's not a white-label mystery compound.

The formulation: an acrylate copolymer with an ethyl acetate mixture. It's specifically engineered for prolonged skin contact — not repurposed from another application.

🛡️

ISO 10993-1 Certified

Independently tested and certified for biocompatibility and skin safety. The same standard used for medical devices that contact human skin.

🚫

PFAS-Free

Contains zero per- and polyfluoroalkyl substances. No forever chemicals. No compromise.

🌸

Hypoallergenic

Formulated for sensitive and reactive skin. Strong enough to hold all night, gentle enough for daily use.

⚕️

Medical-Grade

Engineered specifically for prolonged facial skin contact — not repurposed from packaging or athletic tape.

The Fabric

Bamboo silk, not synthetic

The tape itself is made from ultra-thin bamboo silk — naturally breathable, soft against skin, and strong enough to hold a secure seal all night.

Bamboo silk is inherently hypoallergenic and moisture-wicking. Unlike synthetic fabrics that can trap heat and irritate skin, bamboo breathes with your body — keeping the tape comfortable through the entire night without overheating.

The fabric sits gently on the delicate skin around your lips — softer than cotton, smoother than silk blends. It peels off cleanly with zero residue or redness, even after 8+ hours of wear. Most users forget it's there within 10 minutes.

Full Coverage (3.5" × 2") — A complete lip seal for maximum hold and nasal breathing commitment. Best for experienced tapers and heavy mouth breathers.

Slim Profile Strips (0.7" × 1.6") — A lighter hold that still keeps your lips together while letting you speak or sip water. Great for first-timers. See the first-week guide →

The bottom line

Something that touches your face for 8 hours every night shouldn't be an afterthought. It shouldn't be a mystery. You should know what it's made from, where it comes from, and whether it's been independently tested.

That's the standard we hold ourselves to. Not because it's easy or cheap — but because it's the right way to build a product people trust with their skin, their sleep, and their health. Hear what customers say →
