A fat burning for several minutes after application and very painful to remove. You earn a facial hair removal but regarding blackheads is not insane, far from it. Personally I see no change. So I do not redeem it and recommend it. Not only because several clues lead to think that this is an infringement of an existing product and in addition it is not efficient. With sensitive skin and prone to blackheads I am very disappointed of this product and do not recommend it.
