I had red blotching on my skin when I got out of microsilk and my arms and legs were red. The saleman said its the micro bubbles working, but it did go away. I was only in it for 10 minutes and didnt feel much difference , Im not going with microsilk, science wise not proven either. If I keep getting a reaction and wont be able to use it ,then thats 1500 wasted.. but thanks for info..tiny bubbles not for me ..
