Aquaphor Lip Repair is the one to buy if you want one thing that works, at $4.76. Jack Black Intense Therapy is the one to buy if you are outdoors, because it carries SPF 25. Dr. Dan’s Cortibalm is the one for lips that are split and inflamed rather than merely dry. Skip Carmex if you have been reapplying it all day and wondering why.
A lip balm that says it relieves chapped lips is, in regulatory terms, a drug. Not a cosmetic. 21 CFR 347.3 defines a “lip protectant drug product” as one that temporarily prevents dryness and helps relieve chapping of the lips, and adds that it is “traditionally called lip balm.” To make that claim a product needs one of the active ingredients listed in 21 CFR 347.10, and it has to declare it on a Drug Facts panel.
So we went and looked up what is actually in the ones men buy. We queried the FDA’s National Drug Code directory on 12 September 2026, which is where every OTC drug product in the United States is registered, and checked each pick against it.
Two things fell out, and neither one appears on any other page ranking for this term.
The best-selling lip balm on Amazon is not a drug
Aquaphor Lip Repair ointment has 45,342 ratings. It is the default recommendation in this category and has been for years.
It does not appear in the NDC directory. Searching the directory for Aquaphor returns Aquaphor Original, Aquaphor Healing, the diaper rash products, the itch relief ointment with hydrocortisone, and two lip products — Aquaphor Lip Protectant and Sunscreen and Aquaphor Lip Repair Stick and Sunscreen. Both are sunscreens. The plain ointment in the blue-and-white tube is not listed as a lip drug at all.
That is not a scandal and it does not mean the product is bad — it is petrolatum, it works, and its own buyers are emphatic about it. It means Beiersdorf markets that particular tube as a cosmetic, and a cosmetic cannot claim to treat anything. Read the front of the tube again with that in mind. It says “Immediate Relief,” not “relieves chapped lips.”
One of its five-star reviewers gets there without any of this: “It acts more a barrier and protectant than what we think of chapstick or lip balm” That is exactly right, and it is the most useful sentence anyone has written about the product.
What is actually in Carmex, and why it tingles
The folklore about Carmex is that it makes your lips worse and that you get hooked on it. The usual explanation online is “it has camphor and menthol, which dry you out.” Nobody checks.
The NDC directory lists Carmex Classic Lip Balm Medicated, labeler Carma Laboratories, with two actives: camphor synthetic at 17 mg/g and white petrolatum at 453 mg/g. Marketing category: OTC Monograph Drug.
Now put that against 21 CFR 347.10. White petrolatum is on the permitted skin-protectant list, at 30 to 100 per cent — and 453 mg/g is 45.3 per cent, comfortably inside it. That petrolatum is what carries the chapped-lips claim and it is doing real work.
Camphor is not on the 347.10 list at all. It is not a skin protectant. It is the cooling tingle, and the tingle is what people mistake for the product working.
The honest reading: Carmex moisturises because of the petrolatum, and feels like it is doing something because of the camphor, and those are two different ingredients doing two different jobs. We did not establish which monograph the camphor is listed under — 21 CFR 348, the external analgesic part, is largely reserved — so we are saying only what we could verify, which is that it is not a 347.10 skin protectant.
The rest of the field, checked the same way
O’Keeffe’s Lip Repair is in the directory: avobenzone 2.5 per cent, dimethicone 17.5 per cent, octinoxate 6 per cent, octocrylene 2 per cent. The dimethicone is the 347.10 protectant; the other three are sunscreens. There is a second O’Keeffe’s listing, Seal and Heal, at petrolatum 30 per cent — the exact floor of the permitted range.
Dr. Dan’s Cortibalm carries 1 per cent hydrocortisone, which is a genuine drug active and a different mechanism from everything else here. It is the only pick on this page aimed at lips that are inflamed rather than dry.
How we ranked these
Buyer sentiment first, with review count weighted ahead of review average, and a floor of 4.1 stars, more than 100 ratings, and at least 60 per cent of ratings in the four-to-five band. All six picks clear it. Where the regulatory record changes what a product is good for, we have said so in the pick rather than in the ranking — the FDA work below explains the products, it does not order them.
