Completely useless product, I used it for a week and it did absolutely nothing. It was like opening a bucket and throwing away 15 euros. Truly the most useless product, do not buy it, you will be disappointed

I had previously purchased a similar product, cryopharma spray, and since I couldn't find it available anywhere, I bought the master aid believing that it would do the same job. It's day and night. The master aid does absolutely nothing!

I may be doing something wrong in its use, but it doesn't work as fast as it promises, according to my own observation always.

I used the entire product on a small wart I had on my finger. It simply made it slightly harder to touch without reducing its size at all. In the end, I had it removed by a dermatologist for 40 euros and the story was over.
