I had my first session of tattoo removal yest using the q switch laser & I'm unsure of how to care for it until it heals? It's on the back of my neck which makes it very uncomfy.The treatment itself was excruciating & the rest of the day was awful. I have kept it covered & replaced the dressing once & added some bepathen nappy rash cream. Is it a good idea to keep it covered to avoid irritation from clothing & my hair cos of the area? Is it ok to sleep on my back or will the dressing stick? Help!
