Hey! Yeah, sure, muds are natural products. Certainly, it helps!
I'm still using it. Black one is well-knows for its healing and medicine properties, for ex. Is very good for oily type of the skin. Blue one is good as it helps to release the toxins from the skin. It's very effective in struggling with the spots. There were times when I was taking the baths with the muds.
Jessy, I'm very skeptical about muds as they dry my skin so much..that after I don't know what to put on myself...It has this unpleasant itchy and astringent effect afterwards. Yes, I have an oily skin but it doesn't mean, I need to turn it into a desert)
