Lip Revitalizer contains carvone, an essential oil used as a flavoring agent that can be a significant skin sensitizer and allergen (Source: Planta Medica, August 2001, pages 564–566; and Contact Dermatitis, June 2001, pages 347–356).
Clinically tested formula combines an alpha hydroxy exfoliant with extra moisturizers to restore your lips to a smooth, soft state. Clinical studies show that Lip Revitalizer significantly reduces the appearance of fine lines and wrinkles on the surface of lips within approximately one month of consistent usage.

How this small but longstanding line of lip products has achieved the status of being the solution for cold sores or chapped lips eludes me! Most of these lip products contain enough irritating ingredients to chap anyone's lips. Lots of lip products claim to be medicated, but "medicated" is a dubious term at best, with no regulated meaning.
The way Blistex and a handful of other companies define medicated, it means using camphor, menthol, or phenol in their formulations, yet none of these are in any way, shape, or form "medicines" or "treatments" for dry lips. Quite the contrary, they make dry skin worse and can cause irritation. Products like Blistex can include 0.5% phenol, a potent disinfectant, that is strong enough to actually trigger some serious problems, the least of which are dryness and irritation. It is not something I would recommend for anything but extremely limited use because repeated application can keep your lips chapped forever.
Blistex beckons to you to "discover what your lips are missing," but with few exceptions your lips aren't missing anything with these products except the irritation or inadequate sun protection they provide—definitely an instance where missing something is a good thing! One more thing: Press materials and Blistex's Web site mention dermatologist Dr. Charles Zugerman as an advisor to the company. Yet for a dermatologist whose special interests include allergic contact dermatitis to endorse lip products with known irritants is puzzling to say the least. And if Dr. Zugerman knows about the need for sufficient UVA protection and the ingredients it takes to achieve that, he's not sharing that knowledge on a consistent basis with Blistex. This is just another example of how a dermatologist's endorsement may create an impression of professional credibility, which can be different from speaking to the efficacy or safety of the products themselves.
