Very good soap . Works great on dry skin
Our family favorite bath soaps. Very gentle on the skin , especially for one of my kids who suffer from dry skin and eczema . Even though is fragrance free it has a nice scent to it . I highly recommend it.

Lighter shea butter lotion frugal makes skin dewy
i purchased this a month ago here is what i found it is a lighter lotion it's not as light as cerave daily as it has shea butter but if you like lotions that soften i would recommend this one it does work magic on the skin and is frugal pump works well it does is good for my very sensitive skin bottle size is good it it's over all great value it seems watery but does absorb not in rapid speed but any you would think with shea, shea does soften skin but it doesn't go in too deep into the layers by default so think of that but over all i would say it's a great all year round skin softening protectant
