great gel for sensitive skin. little goes a long way but need to re-apply frequently. The silk'n tite requires 10 minute treatment per area and the gel gets thick and sticky during treatment time, starts to drag the skin a bit. I have found that wiping off, cleaning the device and re applying 2-3 times during treatment solves this issue. however, as said earlier- dont need to use a large amount so a tube lasts through several treatment episodes.
It has not caused any break outs or sensitivity reactions on my skin - which is great.
