This portable device eliminates the need for frequent in-clinic visits, empowering patients to manage their skin conditions independently. It is particularly beneficial for those with limited access to dermatological care or busy schedules, ensuring consistent treatment adherence.

This handheld phototherapy device is clinically indicated for the treatment of several chronic skin disorders, including vitiligo, psoriasis, pityriasis rosea, and eczema. It delivers precise narrow-band UVB light to affected areas, helping to regulate skin cell growth and reduce inflammation associated with these conditions.

311nm narrow-band UVB light targets the underlying causes of skin disorders by modulating the immune response in the skin. For vitiligo, it encourages remaining melanocytes to produce pigment, while for psoriasis, it slows the overproduction of skin cells that leads to scaly plaques.
