careful with temp of sugar or wax-that can do bad damage if just a few degrees too hot. OTOH, I had my legs waxed a few times and it wasn't that uncomfortable (eyebrows, too). The hair on my legs is really fine now and (truth time) I don't bother anymore. They feel smooth until I go and shave or wax them! Husband is fine with it so. . .thats one less chore. I wish my eyebrows would follow the rule, though! They just keep on growing! And Ihave waxed them MANY times. Legs only a few times. Sigh.
Don't use the depilatories on face (or anywhere) Those things are nasty business. It must be inherently wrong to apply an acid to your skin, right?
