Very strong perfumed scent
I wanted to love this soap as it sounds like it has a lot of skin loving ingredients, however when I opened the packaging I was immediately disappointed that there was a strong perfumed scent in the soap. I have extremely sensitive skin that flares up easily if I use scented products so unfortunately I didn’t try this soap because of the smell. I took off 3 stars due to the strong smell. If you like perfumed soaps this most likely won’t be an issue. It’s a decent sized bar so that’s definitely a positive note but because of the scent I was afraid to try it. If they make an unscented version of this soap I may give it a try as this one was a no go for me.
