Use of Ultrasound in Aesthetics
Ultrasound is used in aesthetics in localized fat, cellulite, pre- and postoperative plastic surgery treatments.
Ultrasound produces 3 types of effects: thermal, chemical and mechanical.
- The thermal effect causes increased tissue vascularity and improved local oxygenation
- The chemical effect causes the production of collagen and elastic fibers improving the firmness of the skin
- The mechanical effect causes increased penetration of cosmetic assets by improving the performance of products.
The use of ultrasound activates cellular metabolism, improving lymphatic circulation and venous return, in addition to decreasing healing time due to its anti-inflammatory effect.
Better effects are obtained when associated with other techniques such as lymphatic drainage, endermology, modeling massage and products with actives indicated for each case that should be very well evaluated individually, before any procedure.
Emission mode
Continuous mode – In continuous emission predominates the thermal effect, the application without interruptions can efficiently heat the tissues located to centimeters depth and this depends on the frequency employed. In continuous mode the operating cycle is 100% which indicates a constant ultrasound output and consequently a greater heating.
Pulsed mode – In pulsed emission, between one impulse and another for a time that facilitates the dispersion of heat, so the thermal effect is smaller, potentiating the mechanical or cavitacional effect. Pulsed emission is indicated when the physiological effects of tissue heating are not to be obtained. That is, acute inflammatory conditions, such as in the acute treatment of postoperative scars and sagging cancer (skin sagging).In pulsed emission, the duration of pulse time is variable, so we will have to adjust the cycle and frequency of this wave in pulsed mode. We can find in most ultrasound frequencies of 100Hz, 48Hz and 16Hz and cycles from 5% to 75%.
Frequency
Frequency is the number of oscillations per unit of time of a wave, symbolized by Hz (Hertz), which is equivalent to an oscillation per second, i.e. 16 Hz is equal to 16 oscillations per second, and so on.
Indications
It is indicated in more advanced cases of cellulite and localized fat, for pre- and postoperative treatments and for muscle relaxation.
