**please note: In Fall 2020 the dye that was used to lighten this product has been removed. The natural color of this product is “lemon yellow”. Its consistency should be more liquid than creamy. Once it dries on your skin, there may be some slight residue or tint of color that will eventually go away which will wash off when you cleanse.
