Micro-current treatment has been available in the U.K. for cosmetic purposes since the early 1990s with the introduction of the CACI (Computer Aided Cosmetology Instrument) which became known as the original “non-surgical face-lift”. Treatment claims include the reduction of wrinkles, an improvement in the overall shape of the face, a better complexion and improvements in the appearance of stretch marks and scar tissue. Micro-current therapy can also be used to treat other areas of the body, such as the breast. Tiny micro-currents of electricity are used to stimulate facial or other muscles in the body. The stimulation at this level is known as sub-sensory: that means that you feel very little, if anything at all, and there is no sign of any visible muscle contraction. The muscles are gently exercised, leading to an increase in the production of protein. This tightens and firms up the muscles and reduces slackness and restores a firmer shape and tone to the face or area treated. Prices usually start in the £40 - £60 range for a 30 minute treatment session. Multiple sessions can usually be bought at a discount.
