I've used this mask four times and while nothing bad has happened to my skin, I can't say it has radically improved my acne either.
The consistency of the mask is like actual mud; it isn't clumpy or anything, but comes out in a smooth paste, like clay. It isn't necessarily exfoliating, but there are little gritty particles like real clay or mud. It does go on very smoothly and spreads on my face evenly, but it didn't make my skin feel softer or smoother. Maybe it was because I used this in the shower primarily, but it really made no difference other than leaving a tacky residue on my face, so I had to use my regular cleanser afterwards.
I have pretty sensitive and acne-prone skin so I'm glad this mask didn't cause any blemishes or irritate my face, but it's hardly a miracle product either.
A comprehensive review will be posted to my main blog featuring all of the Adovia products I have tried, including the mask, shampoo, and conditioner.
I received one or more of the products mentioned above for free using Tomoson.com. Regardless, I only recommend products or services I use personally and believe will be good for my readers.
