I used to use Ardell Surgi Cream Depilatory exclusively in the past. That is when I was trying to remove every single hair from my face in this insane act of vanity I had been obsessed with. I used it on a barely there mustache, a few random mole hairs and some light cheek fuzz. It worked well. I think the concept it that it burns the hairs off at skin level. If you are looking for a quick removal cream, this works fast and well. I did not experience any sensitivities to it. I do believe that the hairs did grow back quicker than had I plucked or waxed and darker. I did not care for this.
