Smells like a disinfectant
Size: 16 Fl Oz (Pack of 1)
I’ve been struggling with eczema terribly this winter, scratching to the point of bruising. Nothing seems to help so I figured I’d give this a try. I will say that it does provide instant relief, but it is short lived and not worth the scent. It smells terrible and reminds me of old fashion Pine Sol. I think there are better products out there. I wouldn’t buy this again.

Skin brightness
If you need something for dark spot and brighter skin this is best option, you will need a moisturizer afterwards though.

Great product!
I’ve only been using this soap for a week and I’ve already noticed an improvement. I use it primarily on my face and it has already lightened my blemishes. I’ve been making changes to clean and non-toxic skin/beauty products, so it was nice to find something with all natural ingredients that you can actually pronounce. I’m not a huge fan of the smell but for me the benefits outweigh the smell. I will definitely order again once I run out.
