Useful, good presentation, does its job, only if you pass or put it in the one that does not correspond to your skin, you can get hurt, from a very young age I have had the problem of pimples in my nose passed by squeezing my nose and I only managed to hurt myself, I hope at 63 years old to eliminate that defect, I am happy with the product, as little as you use it is good, I recommend the supplier, thank you
