I must also add that using this product was a painful experience. I didn’t order it from the TV ads - I bought the box at the drug store for about $25. I think it included two spray sizes and a roll-on bottle.
Oh, it removed my chest hair OK, but I guess I didn’t read the label close enough because I didn’t protect my nipples and the resulting pain was excruciating! It warned against using it in the genital area (I can only imagine…) and on the face, but I don’t remember a warning re: the nipples.
Taking a shower afterwards brought tears to my eyes and gasps to my breath. They continued to sting for several days and I eventually covered them with those little round bandages to protect them from rubbing against my shirt. The rest of my chest hair follicles became little red inflamed bumps too, but they recovered sooner.
Now I think my nipples are less sensitive then they used to be - major bummer! 
So my recommendation is: Do NOT use this product! I’ve subsequently used Nair for Men Body Cream with excellent results on my shoulders and feet - but I’m staying clear of the chest!
