Hi ladies

I've come across this e-mail several times and it is an urban legend. The Website is quite complete and explains how this legend came about.
Allergies to products are real however and can be explained by lanolin which is not harmful in itself but a common allergen. Cosmetics can also contain trace amounts of aluminum. There is no consensus on how harmful aluminum really is, but it's generally thought best to avoid it (wikipedia has some good articles). Many cosmetics do contain it as it is used as an anti-clumping ingredient in lipsticks and eye shadows.
