Honestly, I have no clue what my waxer uses but it definitely has aloe in it and it helps a ton. Here's a weird one: once I used the st. ives eye and face stress gel (or whatever it's called - in the green bottle) on an at-home bikini wax and it worked out quite nicely. It's always cool to the touch and the aloe and cucumber in it seemed to do the trick. Of course I have no idea if this is a good idea or not but it felt good to me!
I go to an amazing woman and she rubs aloe all over the waxed area and then makes me go home and ice it. yes, ice. She swears by it and it helps prevent ingrown hairs. I do what she says b/c she is an older Brazlilan woman who's been waxing people for years - so I figure she knows what she is talking about. I prefer the aloe for immediate relief over a product like TendSkin - that burns too much!
