Lawsuit Claims Popular Lip Balm Causes Rash

BOSTON (CBS) – On these cold, blustery days many of us are reaching for lip balms to soothe our dry, cracked lips, including a relatively new product, called EOS. You've probably seen it at drug stores in colorful pods.

Now customers are filing a class action lawsuit claiming that EOS has caused rashes and blisters on their mouths.

It's not clear whether the lip balm is really to blame but it's an important reminder that almost any skin product can cause a reaction called contact dermatitis, whether it's a so-called natural product or not.

So if it happens to you, simply stop using the product.

One of the safest moisturizers you can use on your lips is petroleum jelly, found in Vaseline.
