Let me tell you something no website, no package, no tutorial has EVER told me.
It's all about the POWDER!
Baby/talcum powder that is.... Now, you might be saying "Why would I use baby powder? I want the wax to stick to me." But that is NOT the case.... You want the wax to stick to your hair. When you wax without using powder the wax sticks to the hair and your skin, which will rip your skin a little bit too... (trust me I know). So, it won't make your waxing experience pain free.... you are after all ripping hair from the root.... since the bulb at the end of the hair root is bigger than the pore itself, it spreads open the pore... (which is why you're pores look extra big for a little bit after you wax/tweeze and why it gets red). What it will do though is keep away unnecessary pain. You can apply powder to any area you wish to wax, legs (which don't need as much, since your legs are tough), arms (ditto), bikini, underarms, eyebrows, upper lip, cheek, toes, fingers, chest, back etc etc etc.
Anyways, those are my tips, feel free to post questions.
