Cleared up my skin!
Scent: Unscented, Size: 4 Ounce (Pack of 2)
I have been using this soap for a little over a year. I was on accutane to cure really stubborn acne and when I got off my acne came back. I started using this paired with a beef tallow and honey moisturizer as my only skincare and it cleared up my skin so well. I love this soap and it is so natural and nontoxic. Amazing product.

Great Value for size
Scent: Unscented, Size: 4 Ounce (Pack of 2)
Great value for the size, has an almost milky scent which is quite nice, gentle on the skin, and clean ingredients. If you're looking for body soap without any chemicals, I highly recommend this product.

Truth
Scent: Unscented, Size: 4 Ounce (Pack of 2)
I have used this product for just 4 days now. This will be good and bad. A good all natural soap is not going to sud up like other soaps, I was shocked when I read some of the reviews and suds or the lack of suds seemed to be a big issue. This soap has very little suds. Another issue was smell. I do not notice any smell at all, the next time I order this product I would like to try the lemon for a little sent. This bar will last a long time, a little really gos along way. I do not notice any dryness but my skins feels tighter which makes me think it’s dry. I use my favorite body lotion and all is good. After the first use my skin was noticeably brighter. I had a pimple on my chin that was forming. I left the soap on my face for about 1 min. The next morning the pimple was nearly gone day two completely gone. I use a face cream called Just Tallow and combined with this soap it’s a perfect match. Tonight I put some soap on my feet and scrubbed them with a pumice stone and my feet are so soft right now. This is a good product and I will order again.

Good but not so good
Scent: Mineral Pool, Size: 4.5 Ounce (Pack of 2)
Good soap. If you have sensitive skin or cuts on your hands, it will irritate them. I bought 3 different scents and all 3 made gave my hands inflammation. I really like the smell of them. They make my hands feel soft.
