Had a client last night for a facial ,went through normal routine and after i put the mask on she fell asleep .I didnt want to wake her but the mask was only supposed to be on for 15 mins lol. tryed making afew little noises ,then told her it was time to take the mask off, nothing seemed to work . Eventually she did wake up .Just wondered if anyone else had a problem like this and how did you wake the client up .
