 Multicenter Psoriasis Study7  124 patients were enrolled and 80 completed the protocol. 72% achieved at least 75% clearing in an average of 6.2 treatments. 84% of patients reached improvement of 75% or better after 10 or fewer treatments. 50% of patients reached improvement of 90% or better after 10 or fewer treatments. Common side effects included erythema, blisters, hyperpigmentation, and erosions, but were well tolerated.  Scalp Study9   All patients improved. 17/35 (49%) of patients cleared >95% (mean: 21 treatments; range: 6-52) and 16/35 (45%) cleared 50-95%. Conclusion – The excimer laser is a successful approach to treatment of psoriasis of the scalp, being a simple treatment that can be performed in a short period of time with a high rate of effectiveness.  Sample Studies from 150+ Clinical Studies  Vitiligo Study8  Out of 221 vitiligo patches treated, 50.6% showed 75% pigmentation or more, 25.5% achieved 100% pigmentation of their patches, and 64.3% showed 50% pigmentation or more. Lesions on the face responded better than lesions elsewhere. Conclusion: The 308-nm xenon chloride excimer laser is an effective and safe modality for the treatment of vitiligo, with good results achieved in a relatively short duration of time.  Pediatric Study10  4 children with a mean age of 11.0 years and 12 adults with a mean age of 48.8 years completed the protocol. Both the children and the adult groups yielded a significant decrease in psoriatic severity scores of their respective target lesions. The children’s group had a greater reduction (91.3% reduction) as compared to the adult treatment group (61.6% reduction).   9
