Carmex is one of the most popular and widely-available lip balm brands in the US. The brand describes their products as “medicated lip balm” that can “protect dry, chapped lips.”
But does Carmex contain research-backed ingredients for improving the health and appearance of the lips? Does the brand use any questionable additive ingredients? How do real users rate and describe the effects of Carmex? And can Carmex be addictive?
In this article we’ll answer all of these questions and more as we analyze the ingredients in Carmex based on medical studies to give our take on whether the brand is good for the lips, or if it’s bad for you.
We’ll feature real user reviews and reviews from medical professionals.
The ingredients in Carmex Original are shown above.
White petrolatum is the sole active ingredient, and this ingredient is clinically shown to have an antimicrobial effect (suggesting it has an anti-acne effect), and to support the skin barrier.
This is the same active ingredient in ChapStick and many other commercial lip balms.
Some of the inactive ingredients in Carmex may also support lip health and appearance.
Beeswax is clinically shown to have antimicrobial activity, as we documented in our is ChapStick unhealthy article.
Lanolin is a naturally-derived wax that may have a skin-moisturizing effect according to a medical review published in the Clinical Medicine & Research journal.
Salicylic acid is an effective exfoliator, according to a 2015 medical review.
There are two inactive ingredients in Carmex that may be questionable from a health perspective.
Phenol is an antiseptic compound that may have negative aesthetic and health effects according to a 2023 medical review:
“Dermal exposure to small amounts of phenol will acutely result in a painless, white discoloration of the skin at the site of contact. Deeper burns may occur if decontamination does not occur promptly. The skin may later progress to erythema and blistering”.
Flavor is a broad descriptor that fails to identify the specific flavoring chemicals used. A medical review published in the Environmental Health Perspectives journal suggests that some flavoring compounds and their metabolites may be toxic.
Overall, we consider Carmex likely to support lip health, however we can’t identify any medical studies suggesting this lip balm moisturizes the lips, and we consider this product to be inferior to commercial lip balms like ChapStick.
We do not currently recommend Carmex based on the two inactive ingredients highlighted above.
But how do real users rate and describe the effects of Carmex? We’ll feature some real user reviews in the next section.
