The nails need to be exposed with no polish or products on so the aneathetist can check your nail bed,think its something to do with the oxygen in your blood,but i could be wrong hun,x The reason they advise no make up,theatre is a sterile area,germs could cling to makeup,and the moisturiser would stop the little sticky monitors from gripping to your skin,they need to monitor you under the anasthetic.x
double check i could be wrong,they are worried about infection thats why they give these instructions hun.xThere shouldnt be a prob wearing makeup once your out of theare.x
