Company profile

researched Aug 2026

Cytrellis Biosystems, Inc. (operating as Cytrellis, Inc.) is a medical technology company focused on the development and commercialization of aesthetic devices. Its first product, ellacor, is a system based on proprietary Micro-Coring Technology that removes sagging skin at the micro-scale, intended to address age-related skin changes without the use of energy, surgery, or scarring. The company positions ellacor as a tool for aesthetic practitioners, including dermatologists and plastic surgeons, to treat facial skin laxity and wrinkles.

The ellacor System with Micro-Coring Technology received FDA clearance for use by medical professionals to treat moderate to severe wrinkles in the mid to lower face in adults aged 22 years or older with Fitzpatrick skin types I-IV. Following clearance, the company pursued an initial commercial rollout with a small group of key physicians, with a full national rollout anticipated in 2022. In January 2025, Cytrellis announced an updated next-generation version of the treatment, ellacor 2.0, which it described as supported by new leadership and financing.
