the active ingredient in self tanners dha doesnt penetrate into the bloodstream, just the outer layer of skin that is why it fades away as the layers of skin slough off. I was desperate to use it while pregnant and pasy white in the summer and know people that have used it and had not problem, however i did not due to lack of study. but the real truth is there is no definitive study so to play it safe maybe use a bronzer and sally hansen made a leg makeup that can give you a glow used on arms too and waterproof.. if doing the nursing and choose to self tan, avoid the area that the baby's mouth
touches. Idid use on my face and it cant be worse that the lotions,potions, make up and stuff we use on a daily basis that dont even consider. AH if the glow from motherhood wasnt enough tell it to my legs in shorts! good luck!
