I do believe in the power of this pungent yet viscerally soothing, beautiful soap. It's not easy dealing with late-onset acne like I do, especially on the forehead, but I do tell myself that this soap helps. And I actually really like the smell.
Just a trick: whether you are trying to use this as a soap or a mask, finding the right consistency can be tough. I use a tiny sauce-dish thing to mix the powder with water. Trouble is, if you mix it right before you use it, you are left with painful clumps and a watery, grainy consistency.
My advice is to take maybe two to three teaspoons of the powder in the bowl, and pour just enough water to be able to unclump and mix smoothly (texture should be kind of watery). I leave it on a shelf overnight to use it the next night, and it forms a beautiful pasty, smooth texture.
I leave this paste on my trouble area as a mask until it starts to dry up on my face, and rinse it off with warm water.
This is irrelevant to this soap: but to those of you who struggle with blemishes: after this step I find that it is a good combination to use a honey-cinnamon mask for 20-30 min. The soap is supposed to clean your face of oils and sebum, and the honey mask will restore moisture and annihilate bacteria in the oh-so-hateful bumps on the face.
This in combination with some kind of salicylic acid serum after rinsing off everything, helps (try Evologie Blemish Serum).
