Fordyce spots on lips are caused by sebaceous (oil) glands that developed in an unusual location. Normally, oil glands sit at the base of hair follicles, where they produce sebum to keep skin and hair moisturized. On the lips, though, there are no hair follicles for these glands to attach to. When oil glands form here anyway, they become visible as small, pale bumps on or near the lip line. They are not caused by an infection, poor hygiene, or any sexually transmitted disease.
Why Oil Glands End Up in the Wrong Place
Sebaceous glands are present throughout most of your skin, but they’re usually hidden inside hair follicles where you can’t see them. During fetal development, some of these glands form in areas that lack follicles, particularly the lips, inner cheeks, and genital skin. Because there’s no follicle to contain or drain them, they sit close to the surface and become visible as tiny raised dots.
This happens during embryonic development, meaning the glands are present from birth. However, most people don’t notice them until puberty. That’s because rising hormone levels (particularly androgens) stimulate oil production across the body, and these misplaced glands enlarge slightly as they begin producing more sebum. What was once an invisible cluster of microscopic glands suddenly becomes noticeable as white or yellowish bumps along the lip border.
What They Look Like
Fordyce spots appear as white, yellow, pale red, or skin-colored bumps. They’re small, typically 1 to 3 millimeters in diameter, roughly the size of a pencil tip to a sesame seed. They usually show up in clusters rather than as a single isolated bump, and they tend to appear along the vermilion border (the line where lip skin meets facial skin) or on the inner surface of the lips.
The spots are painless and not itchy. They don’t change in size, don’t form blisters, and don’t scab over. They’re simply there, stable and persistent, for months or years at a time. Some people have just a few; others have dozens spread across both lips.
Who Gets Them
Fordyce spots are extremely common. Estimates suggest that the majority of adults have at least some visible sebaceous glands on their lips or inner cheeks, though many never look closely enough to notice. They affect all skin types and ethnicities. Men tend to notice them more often than women, likely because androgens play a role in how prominent the glands become.
Oily skin may make Fordyce spots more visible. People who produce more sebum overall tend to have larger, more noticeable glands in these ectopic locations. Age can also play a role: the spots sometimes become more prominent with time as the overlying skin thins slightly, or they may fade in older adults as oil production naturally decreases.
They Are Not Contagious
Fordyce spots are a normal anatomical variation, not an infection. They cannot be transmitted through kissing, sharing utensils, or any other form of contact. They are not related to herpes, HPV, or any other sexually transmitted infection. If someone notices them on your lips, there is nothing to “catch.”
How to Tell Them Apart From Cold Sores
The bumps that cause the most confusion with Fordyce spots are cold sores (oral herpes). The differences are straightforward once you know what to look for.
Fordyce spots are painless, smooth, flat or slightly raised, and stay the same over time. They don’t form blisters and don’t scab. Cold sores, by contrast, start with a burning or tingling sensation before any sore appears. They develop as fluid-filled blisters on a red, inflamed base, then rupture, crust over, and heal over the course of two to four weeks. Herpes outbreaks are episodic, meaning they come and go, while Fordyce spots are always present and don’t change.
If your bumps are painless, have been there for weeks or months without changing, and look like uniform pale dots rather than inflamed blisters, they are almost certainly Fordyce spots.
Can They Be Removed?
Because Fordyce spots are harmless, no treatment is medically necessary. But if they bother you cosmetically, a few options exist.
CO2 laser treatment is one of the more studied approaches. In clinical reports, treated areas showed complete healing within about two weeks, with no remaining visible spots and no recurrence after nine months of follow-up. The treatment works by vaporizing the superficial gland tissue. Micro-punch excision, where each gland is individually removed with a tiny tool, is another option, though it’s more tedious for large clusters. Topical retinoids (vitamin A creams) are sometimes tried to reduce gland size, but results are inconsistent and the lip area can be sensitive to irritation.
Any cosmetic procedure on the lips carries a small risk of scarring, so the tradeoff between the appearance of the spots and the potential for a scar is worth considering carefully. Many dermatologists will recommend leaving them alone if they’re not causing significant distress.
Why They Sometimes Get More Noticeable
Several factors can make existing Fordyce spots temporarily more prominent. Dehydration or dry lips can thin the overlying skin, making the glands underneath more visible. Hormonal fluctuations, including those during pregnancy or from hormonal medications, can increase sebum production and enlarge the glands. Stress and high-fat diets have been anecdotally linked to increased oiliness, though direct evidence tying these to Fordyce spot visibility is limited.
Keeping lips moisturized won’t eliminate Fordyce spots, but it can make them slightly less conspicuous by keeping the overlying tissue plump and hydrated. Beyond that, there’s no reliable way to prevent them from appearing, since their root cause is a developmental quirk that was set in motion before birth.
