Abstract: Methods and apparatus for providing a skin treatment device on a pay-per-use basis are disclosed. Generally, a wholesaler supplies an LED skin treatment device to a retailer. The retailer pays the wholesaler on a per use basis, which is regulated by a digital key, such as a smart card attached to the treatment device via a smart card reader. When the value of the digital key drops below a threshold (e.g., only ten treatment sessions remaining), an alert is generated by the treatment device. When the value of the digital key is reduced to zero, the treatment device does not operate until the digital key is replenished or replaced.

Abstract: A light emitting skin treatment device for hands is disclosed. Generally, a wholesaler supplies an LED skin treatment device to a retailer. To reduce the duration of treatments, a partially enclosed system large enough for both hands of a typical user includes a lower panel of LEDs and an upper panel of LEDs. In this manner, both sides of both hands of a user may be treated in one session.
