The laser today represents the gold standard in the medical aesthetic industry. Like the pulsed light, the laser finds its application in the permanent epilation treatments along with the radio frequency and ultimately with the focused ultrasound, is the most popular choice for non-invasive facial lifting. In dermal aesthetic applications it is possible to remove stains, capillaries, warts, tattoos, etc. Without scarcity. There are many types of lasers, and all of them differ in wavelength, power, pulse type (very high pulses to destroy the tattoo pigment, or a low-power continuous laser emission in pain therapy). Fractioned or not, lasers have become today the most used tools in aesthetic medicine around the world. In our center we use different types of laser for epilation applications, fractional skin rejuvenation, tattoo removal, capillary and pigmentation removal, wrinkle treatment, or other skin blemishes. Do not forget pain therapy where the laser along with manual tissue manipulation works in synergy to achieve remarkable results in the shortest possible time.
Unlike lasers, which are coherent and monochromatic light sources, pulsed light is a technology that is based on a non-coherent light source and where the emission spectrum covers 390 nm – 1200 nm.
So, this is a source of light with features completely opposed to those of laser light. The pulsed light applies to larger areas of treatment as the optical aperture often exceeds 10 cm in diameter. The indications for use of pulsed light are mainly related to the spectrum of wavelengths that are emitted by the lamp and then filtered by special optical filters. Outbound filtering serves to limit the absorption of light to the desired chromophories and thus protocols can be created for many applications. In theory with pulsed light it is possible to treat surface pigmented lesions (solar lentils), surface vascular lesions (facial telescopes, rosacea, superficial), epilation and photo rejuvenation of the face. Since pulsed light is not as selective as the laser and knowing the theory of selective photothermolysis it is clear that the treatments have to be performed consciously and personalizing them for each individual client and case. Pulsed light is not a selective monochrome light source like the laser. Superior class equipment offers the ability to work on different skin problems simultaneously both on the structural component and on the texture component (ectasia, oily skin, dilated gold, pigments, etc.), that is, all that comes from the photo aging of the skin . This is why in some cases it is preferable to perform a facial skin rejuvenation treatment with pulsed light in place of the laser.
Electromagnetic waves in the range from 200 kHz to 10 GHz are part of the waves in the spectrum of radio frequencies. When passing through the human tissue, radio waves can lead to different biological effects. Depending on the frequency, power, and coupling method we can differentiate the mono and multipolar radio frequencies of high or low frequency. What is important to know is that monopolar radiofrequency penetrates more into the tissue as the body of the customer and the device are in contact with ground plate electrode, while with the other electrode performing the treatment. Unlike this, in multipolar radiofrequency systems, the return electrode is placed on a handpiece itself, so the tissue penetration is much more superficial and biological effects are much more limited. However, these systems are much safer for the customer.
The lower the working frequency is, the more penetrating into the tissues will be, in accordance with the theory of waves. One of the most macroscopic biological effects is certainly diathermy, that is, the generation of heat inside the tissue. Unlike the laser where there is an absorption of light energy in the pigments, in the radio frequency heat is generated by the passage of the radio waves. This means that radio frequency is a technology that can be used on all fototypes of the skin and throughout the year.
Deep warming of the dermis creates collagen fibers contractions and thus macroscopically creates the skin lifting effect. In addition, microcirculation and neocolagenase were reactivated. Radiofrequency today is a very effective way to treat skin structural problems such as wrinkles, dilated pores, cellulite, and localized fat issues. Since diathermy has an anti-inflammatory and antalgic effect, radiofrequency is now widely used in pain and sports medicine.
Ultrasonic cavitation is an effect that occurs when sound waves with particular characteristics passes through water rich tissues. If all the physical conditions for supporting cavitation are checked, in the interstitial water, water vapour bubbles will begin to develop. The effect is very similar to the effect of boiling water at 100 ° C. All this movement of the water vapour bubbles and thanks to the implosion of the same, makes the membranes of the adipocytes become more permeable and consequently release some of the fatty acids in the interstitial space. As a result, it could be said that ultra sonic cavitation generates a type of gymnastics at a microscopic molecular level.
Said that, it is clear that cavitational treatments are more effective when tissues are rich in water, without which, the cavitation effect is drastically reduced. This type of treatment is the best choice for localised fat but not cellulite treatments, as cellulite is a problem of connective tissue and not localised fat. For cellulite treatments today, more than ever, the best results are obtained with a synergy of radiofrequency treatments combined with manual massage and mesotherapy. During ultra sonic cavitation sessions, it is advisable to take abundant amounts of water. In this way we will not only increase the cavitation effect but will help metabolism to eliminate the toxins produced. For this reason it is practically necessary to combine cavitation treatments with manual lymph drainage, since there is no better way to activate the lymphatic system today. Autosomal cavitation treatments can be performed safely for the client up to a maximum of three treatments per week.
Ultimately, the focalised ultrasound technology has set itself as a gold standard for deeper skin tightening. This is a special technology that utilises ultrasound transducers that focus the sound waves below the skin surface from a several mm to a few cm deep. At focal points, it creates an energy buildup with the following heat release. This simple fact creates the contraction of collagen fibres, stimulates vasodilation and vasoconstriction and the leads to the renovation of the deep layers of the dermis. Generated heat does not depend on the type of tissue and therefore unlike pulsed light, laser and radio frequency, focused ultrasound can be used on all skin phototypes and dermatologic skin types. Treatments can be performed throughout the year but their number is actually very small, at most twice a year. One treatment lasts for 60 minutes, the effects of derma rejuvenation can be appreciated over the next six months. This technology promises excellent results in skin and connective tissue, but unlike laser or pulsed light, it has no effect on surface problems such as pigmentation, capillaries, other inflammation, etc.
Manual tissue handling has remained an essential partner in most treatments where is required tissue mobilisation. The manual mobilisation of the tissues in our center is at the top of the procedures performed either in pain therapy, in muscle relaxation treatments prior to or after intensive training or as stimulation of the microcirculation of localised fat and cellulite treatments. Whether in the various massage techniques or in synergy with the laser or the radio frequency, manual tissue manipulation finds its place of duty in most of today’s treatments.
