Review (5/5): This actually works but pluck or wax first
This product actually works. I was really skeptical at first. In fact, when I first tried it, it didn't work at all even though I applied it every day. But turns out that was because I was using a depilatory cream. That only removes the hair up to the surface, similar to shaving.
Then I read in one of the comments or Q&A that you need to pluck or wax first so that the product can get into the follicle. So I tried that instead. And it worked! Normally my hair starts growing back within 2 or 3 days. This time, it took 3 weeks! And the hair was thinner and there was less of it growing back. I apply it every day. Hopefully after plucking/waxing this second time, it will last even longer.
As for price, this is pretty expensive if you have to apply it every day, forever. But it does come in a larger size for nearly the same price when on sale. I confirmed with the seller that the larger size is the same product even though the packaging looks quite different.
