I just read somewhere (online) that someone uses the PMD to suction his skin after he uses the dermastamp. He doesn't put the discs on it and places the PMD on his skin for a bit. Has anybody done this with the PMD? I have one and would like to give it a try but I'm a little nervous. I'm wondering if it would be too strong to use...this other person said he had no problem with it and that it works great.
I've tried both the PMD and OwnDoc suction device. IMO, the PMD does not provide much of a suction mechanism and the surface in contact is suitable for smaller scars. On the other hand, the OwnDoc device covers a larger surface with a strong force.
Also, with the PMD, the suction force did not give me any bruising. It suggest that its power is rather gentle. Perhaps, you can give it a go on a small scar as a try out patch area.
