This is all a bit out of my circle of competence but we were planning on visiting Perfect Shape (1830:HK), and Modern Beauty (919:HK), other spa chains in HK, so I'll add this one to the list.
Off the top of my head, I can say I've seen the products in the mall before. Doesn't look like a fraud given the high payout record. I will share the notes with you when we meet them!
