I've seen this before, but just not willing to spend that much money... reviews seem favorable, though, so maybe it's not a complete waste.

Pretty much any over the counter acne medication (with benzoyl peroxide) works for me. If I feel a zit coming, I usually dab it on the night before and every day thereafter until it's gone. I don't break out as much as I used to, fortunately!

The other device out there is ThermaClear. According to their website, the ThermaClear device doesn't require frequent tip changes. The tip lasts a year. I don't know if it works as well as Zeno. However, it appears both devices do the same thing.

What is a 'cystic pimple'?

yea it works great if you use it RIGHT when you notice the pimple and treat it 3 times a day, by the next day if i catch it early enough its gone so that is really nice! i usually follow up with the mario badescu drying lotion too... double up and your golden!
