AMAAAAAZING!! I have mild KP on my arms and upper thighs so I decided to do some research on natural remedies. I came across Sea Buckthorn as a potential remedy. So I started with Weleda Sea Buckthorn oil twice daily. Didn't really see improvement, soooo...I went to Sprout's yesterday and picked up some Aubrey Organics Sea Buckthorn soap. I saw a review on here for another version of it, but that one has sandalwood and this one does not. Not sure if that makes a difference. Anyway, about 70% of KP dried up on my arms overnight! But the soap didn't leave the rest of my skin dry - it just dried out the KP. I will have to update after using it for longer, but I KNOW that this soap made a huge overnight difference because I had been using the Weleda oil for over a month with no results. I say give it a try...I paid like $5 for 1 bar which I do not consider expensive, especially for something that works.
