Which is better for visible blackheads and some pimples. Blackhead Eraser or the Wave?

I prefer the Eraser, but you need to make sure you use a moisturizer after (you should always be using a good one anyway.. I recommend BioOil) because any kind of motorized acne remover strips a lot of your upper epidermis off and causes your body to react like it's a scrape and overproduce oil to protect it. Moisturizers help nip that in the bud.
