The idea that "lip balm is addictive" has circulated on overseas forums for years. In Japan, lip balm (リップクリーム, rippu kurīmu) comes in three legal categories — cosmetic, quasi-drug and medicine — and the label tells you what each is for. This article explains how to read them and what the "addiction" story gets wrong.
| Category | Label | Purpose | When to use |
|---|---|---|---|
| Cosmetic | No category shown | Moisturises, prevents dryness, protects the lips | Everyday protection |
| Quasi-drug (医薬部外品, a Japanese category between cosmetics and medicines) | "Quasi-drug" (医薬部外品) | An active ingredient helps prevent chapping | Seasons when your lips chap easily |
| Medicine (Class 3 OTC, etc.) | "Class 3 OTC drug" (第3類医薬品) etc. | For cracked, peeling lips | When you have symptoms. Follow the dosage and directions |
In Japan, an SPF figure on lip balm is permitted for a cosmetic. Lips have no sebaceous glands and are easily affected by ultraviolet light.
[Verify] Check the scope of claims for each category against the MHLW's 56 cosmetic items and the scope of efficacy claims for quasi-drugs.
Lips have no sebaceous glands and a thin outer layer, so they dry out easily. If they feel dry after applying balm, the cause is usually irritating ingredients such as menthol, a licking habit, or friction while applying.
Applying lightly, up and down, along the vertical lines of the lips causes less friction; this is widely shared among people in Japan.
A medicine is for when you have symptoms, within the stated dosage and directions. The usual approach is to switch back to the cosmetic category once the symptoms have settled.
Lips are prone to drying and peeling from UV exposure. Using a lip balm with an SPF figure in the daytime is sensible.
Lip balm touches the lips directly and picks up the bacteria that live in the mouth. Many people use it up within one season to a year of opening, and stop using it if there is discolouration, a change in smell, or separation.
