The FDA-approved Celluma device utilizes advanced LED technology, commonly found in dermatology and MedSpas, to enhance hair density, rejuvenate skin, and alleviate pain from conditions like arthritis. Dr. Engelman highlights its flexible design, which allows for better coverage on curved areas such as the face and joints, making it superior to rigid masks. Users like one shopper report noticeable improvements, including reduced pain and firmer skin, after just a month of use on various body parts. For optimal results, it’s recommended to use the device every other day for 16 weeks, with its specific wavelengths targeting hair growth and skin health effectively.
