I bought DJM's RF instrument before, and it has a sense of design and feels good. I have done my homework for the German brand DJM before, and I was born as a medical instrument before. The effect and safety performance are trustworthy. I bought it and used it for over 1 month. The wrinkle removal effect of DJM RF instrument is quite good. After massaging the eyes, the wrinkles in the corners of the eyes became lighter obviously, but the original spherical RF was different, and the skin condition was obviously better. Beauty instruments are really hot recently, and the prices of beauty instruments on the market are also uneven. If you want to know whether the beauty instrument is reliable, you must first understand the principle and classification of the beauty instrument, and then choose a reliable one according to your own needs. I feel good after using this DJM beauty instrument. . If your problem is solved, I hope it can be adopted.
