neck mask

Hydrogel neck patches typically use a lyocell-based hydrogel sheet with marine- or plant-derived collagens embedded in the matrix. Many sheet masks use a compostable cupra (cupro) fabric as the carrier to hold and deliver the serum.

Sheet masks are usually left on for about 15–20 minutes. The hydrogel neck patch referenced here is intended for about 30 minutes.

Typical features include multiple light colors/wavelengths, adjustable brightness levels, built-in timers, a dedicated neck panel for simultaneous treatment, soft flexible fittings for the face, and rechargeable power/charging ports.
