I just got my serum used it 2 times on vacation and see the tan.. It is definitely nourishing to the skin and no allergic problems with it so far and I am really sensitive ..I can use this on my face as well. It is not too oily.. . I absolutely love the smell and love the oil. It soaks into my skin and leaves it hydrated all day. I do have sensitive skin and must be careful but I love natural products and this product does extremely well on my sensitive skin!
