At home advanced treatments besides our skincare products are certainly becoming the trend of today and whilst we are in the comfort of our home...
Purchased for a teenager with mild acne. Really easy to use (plug in with a long cord) which meant teen was happy to use it (used it while watching iPad).
Pimples seemed to get slightly worst for a week or so and then it really helped to keep skin clearer. (We are also using skin products for acne).
It does seem to need to be used daily to get best results.
