1, safe
To ensure the safety of beauty instruments, we must first see whether there is a third-party certification. If it is an international brand, see if there is any FDA certification. Another point is very important, because the RF instrument transmits heat energy, so the temperature control of the beauty instrument must be done well to see if the machine has a temperature sensor. Excessive temperature may burn the skin, which is not worth the loss.
2. Function
From frequency, waveform, guide head area, use mode and gear number.
The frequency of (1) RF is now 0.3- 1MHz, which exceeds this range and belongs to professional level.
(2) RF is divided into single-stage RF, two-stage RF and multi-stage RF. Single stage is a cinema-level beauty instrument, which can't be touched in daily life. Waveforms belong to the technical category and are generally not displayed, but we can compare the number of leads of the machine. Most leads are basically multilevel RF, which is more powerful and controllable than leads.
(3) The larger the guide head area, the higher the energy generated by the machine and the higher the cost.
(4) It is recommended to choose the one with fewer usage modes and more gears. One more thing, auxiliary functions are also very important. On the basis of radio frequency, if there are other functions such as LED lamp, EMS, infrared ray, ion introduction and export, it is even more worth buying.
Step 3 facilitate
Mainly depends on the flatness, shape and wireless operation of the guide head of the beauty instrument. A person's face is three-dimensional, and a beauty instrument that can take care of the whole face is effective, so the guide head is preferably triangular or circular. The higher the flatness of the guide head and the massage surface, the lower the resistance and the more comfortable it is to operate. Another point is wireless operation, which is very important for people who travel frequently and almost determines the frequency of your beauty instrument.
Expand knowledge: what types of RF instruments are there?
1, single-stage RF instrument
Depth of action: 5-20mm, which can be applied to subcutaneous tissue and dermis, even to muscle layer.
Principle: RF current flows through the whole body, not only for the site to be treated, but also for deeper treatment. The generated electromagnetic waves pass through the soft tissue of the body and heat the skin tissue.
Efficacy: Stimulate deep subcutaneous tissue, tighten skin, effectively dissolve cellulite and stimulate collagen regeneration under dermis.
2. Bipolar RF instrument
Depth of action: 1-5mm, only acting on dermis, unable to penetrate deeply.
Principle: The current takes a short-distance route, which is only aimed at the treatment range and will not affect the deep tissue. In terms of skin care, it is not as good as single-stage RF. Bipolar rf beauty needs to cooperate with single-stage RF or other light source systems to achieve ideal results.
Efficacy: It is mainly used to treat thin skin parts such as eyes and temples. The effect is not comprehensive.
3. Three-level RF instrument
Action depth: 0-20mm, acting on dermis and subcutaneous tissue at the same time.
Principle: Through the conversion of positive and negative poles in three poles, the therapeutic energy can be concentrated in the treatment area, which will make the heat conduction more efficient and deeper.
Efficacy: Stimulate blood circulation and lymph in the body, help to expel fat and toxins, thus achieving the purpose of slimming and beautifying.
