What this trial studies

This is a single-center, prospective clinical evaluation of the CE-marked PALLAS 311 nm solid-state UVB laser used on skin areas such as the face, hands, arms, feet, or legs. Adult patients with skin conditions expected to respond to targeted UVB will receive two approximately 10-minute laser sessions per week for up to three months, with photographic documentation at baseline and monthly. Investigators will record clinical responses and patients will complete a Patient Satisfaction Scale at study end, while also providing feedback on the device's user-friendliness. The study excludes minors, pregnant people, those with epilepsy, active infection or fever, and participants currently in other trials.

Who should consider this trial

Good fit: Ideal candidates are adults with vitiligo, psoriasis, alopecia areata, or atopic dermatitis that is expected to respond to targeted UVB, who can attend twice-weekly clinic visits and provide informed consent.

Not a fit: Patients under 18, pregnant people, those with epilepsy, active infections or fever, or skin disease unlikely to respond to targeted UVB are unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, the PALLAS laser could offer a stable, effective, low-maintenance localized UVB option that shortens treatment sessions and reduces the risk of unpredictable dosing or burns.

How similar studies have performed: Targeted 311 nm UVB and excimer laser treatments have shown benefit for these conditions in prior studies, while the PALLAS device itself represents a newer implementation of that approach.
