Quite simply, I did a test on one armpit to have a comparison with the other. It's been over 10 years now that I pluck my armpits to my epilator and hair grows purposes, but they reject the same. So I let myself be tempted by this.
From the first application, I felt a burning and I had the red and dry armpit for 3 days ... It started badly. But being a warrior at heart, I continue to be applied daily for 3 weeks on my left armpit.
Result, my hairs are more numerous and contained the armpit where I applied the product. Suffice to say that I did not pursue the application and I'm pretty annoyed to have more hair under his left arm as under the law. After so many years of hair removal, it is a return to square one for my left armpit.
In short, I would not recommend at all, and ESPECIALLY NOT if you have sensitive skin because the composition is rather infamous (hence my allergic reaction).
