The design is great. Very good result from the 1st application.
Very pleasant surprise by its effectiveness! It removes the pimples and the inflammation goes down quickly. On the other hand, it is necessary to provide recharging arrows for intensive use, the arrow is fast.
Following my purchase on 11/27: after 10 days of use at a reasonable rate of 3 times a day for 2 minutes I have begun to see an improvement in my skin and a reduction in my acne. Used in addition with the application of a moisturizer I hope I can get to the bottom of my adult acne.
My daughter is delighted with this product!
