My face was left swollen and bruised after the threading for about 3 days afterwards, and the gel nails didn’t even last a week before chipping or peeling off completely!
Had a Hollywood wax here, it took a about half an hour. I had Donna, who seemed very nice. A few small hairs were left behind in the most sensitive area, but overall the wax looks great and I'd prefer a few left behind rather than being made too sore through tweazing. It does what it says on the tin.
