Strata Skin Sciences, formerly known as MELA Sciences, is a medical technology company specializing in the development and commercialization of innovative dermatology products. Founded in the early 1990s and rebranded in 2016, the company focuses on advancing treatments for a range of skin conditions by leveraging patented electrical and light-based therapies. Headquartered in Horsham, Pennsylvania, Strata Skin Sciences has established a reputation for delivering novel solutions that address both chronic and acute dermatological needs.
The company’s flagship offering is the XTRAC® phototherapy system, designed to treat psoriasis, eczema and vitiligo through targeted ultraviolet light. XTRAC utilizes a monochromatic excimer laser to deliver high-dose, precision light energy directly to affected areas while minimizing overall UV exposure. This approach has positioned XTRAC as a leading in-office treatment option for patients and clinicians seeking alternatives to systemic therapies or broad-band UV exposure.
In addition to phototherapy, Strata Skin Sciences markets a portfolio of surgical and tissue management devices for Mohs micrographic surgery. Its MohsCold® cryosurgical instruments and disposable tips are engineered to optimize tissue preservation and operator efficiency during skin cancer removal procedures. The company continues to expand its pipeline by exploring complementary technologies that support both diagnostic and therapeutic workflows in dermatology clinics.
Strata Skin Sciences distributes products across North America and Europe, supporting a network of hospitals, dermatology practices and specialty treatment centers. The organization is guided by an experienced leadership team with deep expertise in medical devices, clinical development and commercial strategy. By combining scientific innovation with targeted outreach and training programs, Strata aims to improve patient care and drive wider adoption of advanced dermatologic therapies.
