Your results may vary. During the treatment you may feel comfortable heat, but you should never feel an unpleasant burning or pain sensation. Treatment should not be applied over hair or scar tissue, or if you have electronic or metal implants. Side effects may include temporary damage to natural skin (crust, blister, and burn). As with any medical procedure, ask your doctor if the EMFACE® procedure is right for you. EMFACE® is indicated to provide heating for the purpose of elevating tissue temperature for selected medical conditions such as temporary relief of pain, muscle spasms, and increase in local circulation. EMFACE® applies muscle stimulation resulting in induced muscle workout. ©2022 BTL Industries, Inc. and affiliated companies. All rights reserved.
