I read reviews on a lot of masks sold on here before I decided on this one! In my search I was looking for one that was all natural and chemical free. There are other shea terra brands that are chemical free, but I went with this one because of the acne fighting properties of it's ingredients.
I have been using this mask for over a month. I always have breakouts on my chin. I will put this on at night and leave on my face all night for spot treatment. (I go to bed once it's dry and it stays in place all night) In the morning not only are any blemishes dramatically reduced in size, but former scars are less noticeable! This has been a great mask for spot treatment and clearing blemishes on your face.
For mixing... since it is powder, it's a huge plus in getting a bang for your buck but also a little tricky. I just put a tiny amount in a hairspray cap, use my finger to add water drop by drop until it is a soft paste, and apply to my face.
The scent... a couple of the reviews mentioned hating the smell. It has thyme and turmeric in it. It mostly smells like that...herbs! Also... it is a bit challenging to get off. I just use warm water and then a towel to help get it off easier.
