STRATA Skin Sciences (NASDAQ: SSKN) highlighted a February 17, 2026 meta-analysis showing 308 nm excimer laser therapy produces substantial PASI improvements in plaque psoriasis. Reviewed trials (n sizes 20–100) reported PASI reductions of ~56%–85% with 10–14 treatments over 5–7 weeks. The analysis emphasized MED-guided dosing and session fluences typically 200–600 mJ/cm² (1–3× MED), with some protocols using higher multiples. STRATA noted its high-power XTRAC technology supports delivery of targeted high-fluence doses efficiently, enabling short treatment times and lesion-directed therapy while sparing healthy skin.
