Clarteis

Clarteis is a specialized medical device firm focused on dermatology phototherapy. Its core innovation is the exciplex® device, which it claims is the smallest monochromatic excimer light source for treating localized skin conditions like Vitiligo, Alopecia Areata, and Psoriasis. The company targets a global market of dermatologists and medical device distributors, positioning its product as an office-based, precise treatment alternative to larger, less targeted phototherapy systems. As a private entity, it appears to be in the commercial stage with its first product, though its specific financial and operational scale is not publicly detailed.

Proprietary miniaturized excimer light source (exciplex®) emitting monochromatic ultraviolet light (308nm) for localized phototherapy.

Clarteis competes in the dermatology phototherapy segment against companies offering excimer lasers (e.g., Ra Medical Systems' Pharos), traditional UVB phototherapy cabinets, and broadband light devices. Its key differentiation is the claimed smallest form factor for a monochromatic excimer source, targeting the niche for precise, office-based treatment. It must also compete with pharmaceutical treatments for the same conditions.
