New Peer Reviewed Publication of Combination Therapy in Vitiligo with STRATA Skin Sciences’ Excimer Laser and JAK Inhibitors Demonstrated Superior Safety and Unprecedented Response Rates, Providing Continued Validation of Personalized Medicine Approach

STRATA Skin Sciences, Inc. (“STRATA” or the “Company”) (NASDAQ: SSKN), a medical technology company dedicated to developing, commercializing, and marketing innovative products for the treatment of dermatologic conditions, highlights a recent peer reviewed and randomized controlled study of its 308nm Excimer laser in combination with an oral Janus kinase (JAK) inhibitor that demonstrated superior efficacy, unprecedented response rates, and excellent safety profile relative to monotherapy or conventional treatment. The 251-patient study, published in the International Journal of Dermatology, titled “ 308nm Excimer Laser Combined with JAK Inhibitors for Adult Localized Non-Segmental Vitiligo: A Multicenter Randomized Controlled Trial,” illustrates the continued interest in the Company’s well-established technology, in addition to showing more rapid, better results and durable repigmentation in combination vitiligo therapy relative to monotherapy. The study is also supportive of the Company’s current pursuit of expanded reimbursement for a variety of indications, including vitiligo, psoriasis, and others.

The study counts five key findings relating to the combination of Excimer Laser and JAK inhibitor :

Mechanistic Synergy – pointing out that the synergy likely arises as JAK inhibitors suppress IFN-γ–driven CD8+ T-cell cytotoxicity, whereas excimer laser promotes melanocyte migration through UV-induced paracrine signals like α-MSH and endothelin-1.

Superior Efficacy – showing a 14.20% higher repigmentation, indicating synergistic effects.

Unprecedented Response Rates – following 52 weeks of treatment had a 100% significant efficacy rate.

Durable Stability - At 1-year follow-up, the combination group demonstrated the highest pigmentation stability (96.5%) and lowest relapse rate (8.8%), outperforming the monotherapy and control groups.

Excellent Safety Profile - No serious or persistent adverse events occurred.

Strata CEO Dr. Dolev Rafaeli commented, “This investigator-initiated study, which features a much larger patient population than normally seen in contemporary dermatology studies, highlights the continued interest in our Excimer laser technology, and the promise of combination therapy. It is even more encouraging in light of the fact that our technology has been in use for around 20 years. Dermatologists continue to rely on the superior performance of our Excimer technology for durable repigmentation in these difficult to manage immunomodulated skin conditions. The addition of JAK inhibiting treatments has enhanced the efficacy of the therapy without compromising safety, and repigmentation has shown high stability with very little relapse.

“These results were published in the last month, adding to a wealth of over 400 studies and/or peer-reviewed papers that exists in the literature today, which we believe to be a strong validation of our recent application for expanded reimbursement. Care providers continue to rely on the value of our approach, which in combination therapy with JAK inhibitors and other therapies, can be considered personalized medicine given the duration of the laser exposure and dosage of the corresponding treatment. We continue to work with regulators to provide expanded access to our treatment modality by the beginning of 2026,” concluded Dr. Rafaeli.

This pivotal trial adds to the substantial body of clinical evidence confirming the 308 nm excimer laser as a cornerstone therapy for inflammatory and autoimmune skin diseases, including vitiligo, psoriasis, atopic dermatitis, alopecia areata, and lichen planus. With 251 patients enrolled, this study provides a robust evidence base, offering sufficient power to support the reliability and generalizability of its findings. With over two decades of published data, excimer laser therapy is uniquely positioned as a proven, targeted, and safe treatment option across a broad range of dermatologic conditions.

Excimer laser continues to play a pivotal role alongside emerging systemic treatments, ensuring patients have access to therapies that are not only innovative, but also clinically validated, targeted, and safe.
