The Silk'n HST is an over-the-counter home use device intended for non-invasive treatment of mild to moderate periorbital wrinkles for adult women who have Fitzpatrick skin types I-IV.
The Silk'n HST device is designed as a hand held device, which utilizes both RF and low power light energies. The device includes RF generator, LEDs at wavelengths of 630±20nm and 850±20nm (red and IR wavelengths, respectively) and a temperature stabilizer. The Silk'n HST device consists of an applicator and an adaptor. The applicator is a handheld unit used for treatment. The treatment surface is located at the applicator tip and comes in direct contact with the skin. The applicator is equipped with an ON/OFF switch that also selects the energy level as manifested using indicators panel. The adaptor connects the applicator to the electrical outlet using its plug and the applicator socket.
Here's a breakdown of the acceptance criteria and the study proving the device meets them, based on the provided text:
