Fordyce spots are caused by oil glands that developed in the wrong location during embryonic growth. These glands, which normally sit alongside hair follicles, instead ended up in hairless areas of skin like the lips, inner cheeks, or genitals. They’re present from birth but typically become visible during puberty or later in adulthood as hormonal changes cause them to enlarge. They are not infections, not contagious, and not a sign of disease.
How Fordyce Spots Form
Your skin contains millions of tiny oil-producing glands called sebaceous glands. Normally, these glands are attached to hair follicles and release their oil (sebum) through the follicle opening onto the skin’s surface. In Fordyce spots, the glands formed without any attached hair follicle during fetal development. Instead, they sit just under the surface and open directly onto the skin. Because there’s no follicle to channel the oil through, the gland itself becomes visible as a small raised bump.
Each spot consists of a single oil-producing gland lobule with a duct that opens straight to the surface. The spots appear as white, yellow, pale red, or skin-colored bumps ranging from 1 to 3 mm across. They can show up as a single spot, a small cluster, or dense groupings of 50 or more.
The Role of Hormones and Aging
Many people have these misplaced glands from birth without ever noticing them. They become visible when hormonal shifts, particularly the surge of androgens during puberty, stimulate oil glands throughout the body to grow and produce more sebum. The ectopic glands respond to these same signals, enlarging enough to become noticeable under the thin skin of the lips or genital area.
The number and visibility of Fordyce spots tends to increase with age. Researchers believe this reflects the cumulative effect of hormonal exposure on the glands over time. This age-related progression is one of the strongest clues pointing to an endocrine (hormonal) influence on their development, though the exact mechanism still isn’t fully understood.
A Possible Link to Cholesterol Levels
Because sebaceous glands are deeply involved in fat metabolism, researchers have investigated whether blood lipid levels play a role in making Fordyce spots more prominent. The connection appears to be real: people with dense clusters of Fordyce spots (more than 100 granules) tend to have significantly elevated total cholesterol and LDL (“bad” cholesterol) compared to people without them.
The underlying logic is straightforward. Oil glands produce sebum, a substance rich in cholesterol and its derivatives. When systemic lipid levels are high, the glands can grow larger as they process more circulating fats. This overgrowth makes them clinically visible, especially in areas where the skin is thin. The association was specific to total cholesterol and LDL. Triglycerides and HDL (“good” cholesterol) did not show a meaningful difference. Dense oral Fordyce spots may therefore serve as a visual clue worth mentioning at your next blood work appointment.
What Fordyce Spots Are Not
The location of Fordyce spots, particularly on the genitals or lip border, leads many people to mistake them for something more serious. They are frequently confused with genital warts caused by HPV, herpes blisters, or other sexually transmitted infections. This confusion goes both ways: patients and sometimes even physicians initially suspect an STI.
A few features set Fordyce spots apart. They don’t change shape, don’t ulcerate, don’t itch, and don’t spread from person to person. Under magnification, they appear as round white-yellowish clusters, sometimes with a tiny brighter dot in the center marking the gland’s duct opening. HPV warts, by contrast, show a distinct pattern of dotted blood vessels over a pink or tan base. If you’re uncertain about what you’re seeing, a dermatologist can distinguish between them quickly using a dermatoscope.
Treatment Options
Fordyce spots are harmless and don’t require treatment. Most people who seek removal do so for cosmetic reasons, particularly when spots are prominent on the lip border or vermilion.
The most common approaches include laser ablation, cryotherapy (freezing), electrodesiccation (using electric current to destroy the gland), and micro-punch surgery. Among laser options, CO2 laser using a pinhole technique has shown strong results. In published case series, patients saw significant cosmetic improvement within 6 to 16 weeks, with no recurrence in treated areas during follow-up. This approach offers relatively short recovery time and minimal scarring compared to older techniques.
Topical treatments like tretinoin (a vitamin A derivative) and oral isotretinoin have also been used. These work by reducing oil gland activity, but the spots often return once treatment stops. For most people, the practical decision comes down to whether the spots bother them enough to justify a procedure, since the spots pose no health risk on their own.
