Lyn, I found at K-Mart.

It is their brand "American Fare" and says 'Maximum Strength Acne Medication' 10% Benzoyl Peroxide. It says Vanishing Gel at the bottom. It is in a tiny 1 ounce bottle that I bought over a year ago so it might be up to $3 by now, LOL.

My friend found some at Walmart but in their brand; Equate? She says it worked it's magic on her son. We both have pre-teen boys.

You do have to be very careful to wear something white and use white pillowcases and towels if you use this product on your face as it will bleach colored sheets and towels.

All I know is the Salycic (spelling?) Acid does nothing; for me anyway!... It is the Benzoyl Peroxide that works.

Hope that helps!?

Sorry to get off of the Zeno subject... just think the BP might be worth a try???
