Mask Base: Most versions are made from high-quality PVC (Polyvinyl Chloride) or durable plastic.
Lighting Source: The "LED" effect is actually produced by EL (Electroluminescent) cold light wire. Unlike traditional bulbs, this wire produces no heat and no UV radiation, making it safe for close contact with the face.
Comfort Padding: To prevent skin irritation, the interior forehead area typically features foam or sponge padding.
Fasteners: The mask is secured using an adjustable elastic strap.
Electronics: It includes a small plastic battery pack/controller connected by a cord, typically powered by 2 AA batteries.
