Lumenis Lightsheer Diode Laser and Facial Hair Removal - Is It Safe?

Ive done 1 treatment on underarm and upperlip.I now want to include brazilian & full face.Im asian-light brown skin & fine,dark hair.I dont know if I should do the whole face or stick to what im doing now,as thats where the hair is thicker.I can continue waxing the sides.Does waxing damagae the skin?I've heard that medically the hair on sides of face needs to be there?Can laser cause acne as the skin is exposed?I do get breakouts.Can brazilian laser cause circulation problems and prevent orgasm?
