Introduction
For skin tissue, when its temperature rise over 40 degree Celsius, its blood circulation is expedited as blood flow is increasing, which promotes metabolism. 
In addition, hormone secretion becomes normalized due to expedition of blood circulation and cells are activated with oxygen provided by discharging toxics which prohibits secretion of melanic pigment.

Radio frequency (RF) is the latest beauty technology. RF skin-tightening treatment is an effective way to rejuvenate skin, reduce wrinkles and enhance skin elasticity. The RF heats the dermis, the deepest skin layer, without damaging the epidermis, the top layer of skin. It stimulates the structural change of the collagen fibers and elastic fibers to its original elasticity, reducing lines and wrinkles. An immediate skin-tightening effect will then be achieved without risk.

Also, radio frequency can promote tissue metabolism, repel cellulite, tighten the skin, strengthen the skin's elasticity, and so on. Its effect will last for a long time. Meanwhile, it can enhance muscle elasticity and improve cell metabolism. It creates effect like internal explosion, meaning that the expansion and compression of waves produce a lot of tiny spaces inside the liquid. The gas and vapors exist in these tiny spaces. In the compression cycle, supersonic waves impose a positive pressure on the liquid molecule, whereas a negative pressure is created through the expansion cycle. There is a cohesion effect inside the liquid or biological tissues. Inside the low-density lipocyte, the cohesive effects are comparatively weak. A negative pressure, which is relative low, can create tissue gaps easily. It is called cavitations in physics. The effects of the explosion inside and outside the cells will increase the molecular movements so as to achieve a high energy state, which then leads to the lipocyte cracking. 

Managing wrinkles or skin rejuvenation
This device transfers high frequency RF energy to skin and stimulates to produce collagen in skin layer. 
In this case, stimulated collagen tissues are activated and thus help prevention of wrinkles due to stress and help expedition of skin rejuvenation.

Managing freckle and skin-whitening effect
This device could alleviate freckles due to deteriorated blood circulation in a way that high frequency RF energy is transferred to skins and blood circulation is expedited and it also helps skin-whitening effects by reducing melanic pigment secretion.

Managing pimple(Acne)
Heat is generated on skin tissue by transferring high frequency RF energy. When heat is generated in skin tissue, antibiotic effect is activated and then it normalizes sebaceous glands and regulates secretion of sebum, which helps to reduce secretion of pimples(acne).

How to get it works
