How INNVEIL Works
Revolutionary LLLT hidden in plain sight
The 4-Layer Therapy Liner
2mm total thickness — thinner than a coin
Layer 1: Adhesive / Velcro
Medical-grade adhesive bonds liner to cap interior. Removable for cleaning.
Layer 2: Flexible PCB (FPC)
6-petal geodesic circuit board with 180 VCSEL lasers facing downward toward scalp.
Layer 3: Holographic Diffuser
Luminit LSD® 80° film spreads each laser beam from pinpoint to 3.5mm spot for uniform coverage.
Layer 4: Medical Silicone Pad
Shore A 25-30 silicone provides comfort, thermal isolation, and consistent skin contact.
Total liner thickness: 2.0mm — undetectable when worn
180 Lasers. One Mission.
6-petal geodesic array covers the entire AGA zone
6 petals × 30 VCSELs = 180 total
Verified at 55 / 57.5 / 60 cm head sizes
Why VCSEL?
Vertical-Cavity Surface-Emitting Lasers are thinner than LEDs, produce a perfect circular beam, and enable our ultra-thin flexible PCB design. The same technology used in iPhone Face ID.
Coverage Area
~200 cm² covering the entire androgenetic alopecia zone. Each VCSEL delivers 5mW to an 80°-diffused spot, achieving 4.0 J/cm² fluence in a 15-minute session.
