I must say that I'm excited already hellauf after the first application round. The device, a compressor like flounder, which can be opened by pressing a button is ultra light and intuitive to use. However, you should take a look in the manual.
A small filter is to be placed before each use in the suction hose (of work page already exists), then comes the metal rod treatment with the chosen essay on it (coarse, fine with a larger diameter and an attachment with a small diameter can be selected). The principle is simple: through its trunk, the skin is easily sucked and raised (five intensity levels are here to choose from); the essays are equipped with sapphire, and you drive slowly through the skin areas that you want to treat. Thus, the skin surface is exfoliated and also - so it should in any case be - activated at the cellular level. The regeneration is stimulated; defective skin areas (eg pigment changes) to be played back "chic".
The latter longer term effect, I can not confirm, but rather, that already after the first treatment the skin is much more even and more radiant than in any peeling, that I have ever used. In this respect, the treatment is an absolute success with the Beurer device.
I have a little doubt that the Sapphire features the essays keeps permanently - it remains to be seen; the parts are in any case not declared as pure replacement parts / consumables. If the effect results in something negative, I complete the review accordingly.
The unit gets only once a full recommendation from me - it creates a real "wow factor" when it comes to the skin appearance, a certain glow, and that's great!
