I only signed up on MUA to review this product.
I love it so much.
It has cleared up ALL my back acne and I really do think it is amazing. I use Clinique Anti blemish spray on my back afterwards and this seems to work well alongside it.
I will be repeatedly buying this product 100%.

I bought this for my chest acne and had high expectations because it smells like prescription acne medication (well, at least it smells strong). Unfortunately, I can't say it's done a whole heck of a lot, other than to dry out my skin.

This acne-fighting astringent from Mario Badescu is for use on the back and chest only, it's too harsh for facial skin. I was skeptical about it because of its odd ingredient list: Deionized Water, Boric Acid, Isopropyl Alcohol, Camphor, Gum Benzoin, Hydrolyzed Yeast Protein. I'm used to using anti-acne products with BP, AHA, or BHA (none of which were reliably keeping my back clear!) Anyway, after using it twice a day for a week, all the breakouts on my back were gone! It has kept my skin consistently clear. I am amazed and very pleased. Will definitely repurchase.
UPDATE: This seems to have stopped working. :( I guess it is no match for the heat and humidity! continued >>
