Is the derivation instrument really useful? The concept of ion derivation has no corresponding English vocabulary, so there is no relevant scientific literature to support it. And looking around, all kinds of big-name beauty instrument companies in Europe and America are not doing ion derivative instruments. These instrument manufacturers claim that by attaching negative ions to the dirt on the face and using the suction of positive ions to suck it out, the dirt that facial cleanser can't wash away in sunrise life can be washed away, thus realizing real deep cleaning.
To be honest, this view is correct. But! But! It can only be realized in an insulated state.
My shallow knowledge of physics tells me that the human body is conductive, and when the dust is charged, it will be led away by the human body. So dust will only be charged in the air, not in the human body. Chargeless dust will not be affected by electric and magnetic fields, nor will it be attracted.
Some people want to say, but after I used it, the cotton pad was really dirty. Those dirty things are actually cotton pads that are wiped back and forth on the face, which is also commonly known as exfoliation. Because the instrument has vibration function, it is equivalent to a vibrating cleaning instrument, and the cotton pad is the bristle. When the make-up water softens the stratum corneum, it is difficult to completely remove the clean dirt when washing your face by hand, and it is easier to be wiped off by a cotton pad.
Conclusion: Although I don't agree with the concept of ion derivation, these instruments do have a cleaning effect!
The function of ion export of the export instrument: softening keratin, softening tissue and strengthening skin cleaning power.
Iontophoresis: Introduce more nutrients into the deep skin, generate oxygen to nourish the skin and make the tissue more compact.
The function of iontophoresis is to introduce more nutrients into the deep skin, so the focus is on product collocation. If you use a product that does not meet the import conditions and use a bad product, you will naturally not see the due effect.
The principle of export instruments is ion and ultrasonic, which are used for export and import, such as Hitachi n2000 and Yaman hrf- 1. Only when the product is used correctly can it be effective. This instrument only plays the role of cleaning and helping skin care products to absorb.
The main principle is to use the positive and negative attraction between ions.
The products suitable for iontophoresis are oil-free, silicon-free and alcohol-free. High-concentration products?
