Lanolin

Lanolin: Lanolin is the oil produced by the sebaceous glands of sheep, and found in nipple creams, lip balms, and lotions. Wool is treated with a heavy dose of pesticides before the lanolin is scoured out of it, and thus lanolin is considered an immunotoxin by EWG. It is undoubtedly, however, an effective treatment for nipple trauma, as demonstrated by several studies. Skin Deep score: 4
