White bumps on the face that are not milia

Many small white or pale bumps on the face look like milia when you first see them. Some are harmless oil glands or sweat gland growths. One is a contagious virus. A few are skin cancer. This guide describes each lookalike only as far as the medical sources describe it, so you know what to ask a doctor. It cannot tell you what your bump is. A doctor who examines your skin can. For what milia themselves are, see the hub guide, what milia are.

Skinli gives general education and is not a doctor.

First, what milia look like

StatPearls, a medical reference hosted by the U.S. National Library of Medicine, describes milia as "small, white-to-yellow, smooth, dome-shaped papules measuring less than 3 mm," which "in darker skin, they may show a subtle blue tint." They are firm, hold solid keratin, and are "commonly asymptomatic," meaning they cause no pain or itch. In adults they "tend to occur on the eyelids, cheeks, forehead, and genitalia."

StatPearls names the conditions doctors must tell apart from milia: "The principal differential diagnosis is sebaceous hyperplasia," and "Other differential diagnoses could include comedonal acne, flat warts, and milia-like idiopathic calcinosis cutis."

Sebaceous hyperplasia

This is the lookalike StatPearls puts first.

• What it is. Enlarged oil glands. StatPearls says the glands "are normal in structure but increased in number."
• What it looks like. "Skin-colored or yellowish papules localized on the face (forehead, cheeks, chin) or in the upper trunk," with "a central dell," a small dent in the middle. The bumps "are soft and vary in size from 2 to 9 mm."
• Who gets it. Mainly "adults of middle age or older." StatPearls also says it is common in newborns, from exposure to the mother's hormones.
• Why it matters. StatPearls says "The main concern is the clinical resemblance with other neoplastic lesions such as sebaceous adenoma and basal cell carcinoma," and "A biopsy may be necessary to rule out basal cell carcinoma."

So compared with milia: softer, often yellow, often larger, with a dent in the middle.

Whiteheads

The American Academy of Dermatology (AAD) says a whitehead forms "when excess oil and dead skin cells build up and plug the opening of a pore," and looks "raised and white or flesh colored." Whiteheads are acne and usually come with other acne. The guide milia vs whiteheads compares the two in full. The guide sebaceous filaments covers the normal oil plugs in nose pores, which people also confuse with both.

Syringoma

• What it is. StatPearls says syringomas are "benign neoplasms," harmless growths, that come from sweat ducts.
• What it looks like. "Skin-colored papules, often concentrated around the periorbital region," the area around the eyes, "with a heightened prevalence on the lower lids." They are "multiple, discrete, firm papules measuring 2 to 4 mm."
• Who gets it. StatPearls says they appear "during early adulthood, exhibiting a predilection for females and those of Asian heritage."
• How it is confirmed. StatPearls lists milia among the conditions syringomas are confused with, and says "A skin biopsy is valuable when diagnostic uncertainty arises."

Xanthelasma

• What it is. StatPearls describes "soft, lipid-rich deposits, particularly cholesterol."
• What it looks like. "Semisolid, yellowish papules or plaques," usually on the inner corners of the upper and lower eyelids, often on both sides.
• Why it matters. StatPearls estimates that 50 percent of adults with xanthelasma have abnormal blood fat levels and says "conducting a serum lipid profile is advisable," meaning a blood fat test. MedlinePlus says xanthomas "may be a sign of a medical condition that involves an increase in blood lipids."

A yellow, flat patch on the inner eyelid points to xanthelasma. A tiny round white dome points to milia. Both are reasons to see a doctor, and xanthelasma is a reason to check your cholesterol.

Molluscum contagiosum

• What it is. MedlinePlus says it is "a viral skin infection that causes raised, pearl-like papules or nodules."
• What it looks like. The NHS says the spots are 2 to 5 mm wide and "are raised and dome-shaped with a shiny white dimple in the middle." MedlinePlus says "The papule often has a dimple in the center."
• Why it matters. It spreads. MedlinePlus says it passes by "direct contact with a skin lesion or an object that has the virus on it," such as "towels, clothing, or toys." Near the eye, the StatPearls eyelid chapter says it can cause ongoing eye irritation.

The central dimple is the main clue. StatPearls describes milia as smooth domes.

Basal cell carcinoma

This is the lookalike that matters most, because it is a skin cancer.

• MedlinePlus says basal cell cancer can be a bump or growth that is "Pearly or waxy" and "White or light pink," and that "It may not look that different from your normal skin."
• The AAD lists a "Cluster of shiny bumps" and a "Firm, round, and raised growth" among its signs, and says most develop "on the head and neck," including the eyelids.
• The AAD adds: "you cannot rule out or know whether you have this skin cancer by looking at pictures."

MedlinePlus says to contact a provider for a spot that changes in appearance, color, size or texture, or that "becomes painful or swollen," or "starts to bleed or itch."

Milia-like calcium deposits

StatPearls lists milia-like idiopathic calcinosis cutis as a lookalike. Idiopathic means with no known cause, and calcinosis cutis means calcium deposits in the skin. A 2021 review in Dermatology Online Journal describes it as "a benign cutaneous disorder consisting of calcium deposits," "typically associated with Down syndrome," and says the bumps "tend to self-resolve as patients reach adulthood." A biopsy shows the calcium.

Keratosis pilaris

The AAD says keratosis pilaris "appears as tiny bumps on the skin" that "look like goosebumps or the skin of a plucked chicken." It says "These rough-feeling bumps are actually plugs of dead skin cells," most often on the upper arms and front of the thighs, and that "Children may have these bumps on their cheeks." The rough feel and the spread over an area set it apart from single smooth milia.

Epidermoid cysts

StatPearls says that in newborns, "small epidermal cysts, referred to as milia, are common." Larger epidermoid cysts in adults are a related but different lump: "a non-fluctuant, compressible mass measuring 0.5 cm to several centimeters," often with "A central, dark comedone opening (punctum)." That makes them 5 millimeters or more, larger than the milia StatPearls describes.

Heat rash

The NHS describes heat rash (miliaria) as "small, raised spots" with "an itchy, prickly feeling," which on brown or black skin may "look grey or white." The NHS links it to heat and sweating, and it itches. StatPearls describes milia as commonly asymptomatic.

Fordyce spots on the lips

White or yellow specks on the lips and inside the cheeks are often Fordyce spots. StatPearls, in its sebaceous hyperplasia chapter, explains that some oil glands "open directly towards the epithelial surface: in lips and buccal mucosa (Fordyce spots)," buccal mucosa being the inside of the cheek. The guide milia on lips compares them with lip milia.

Flat warts

StatPearls lists flat warts among the conditions that can look like milia. MedlinePlus says warts are "caused by a virus," and its skin lumps page shows flat warts on the cheek and neck. Ask a doctor to check any rough or flat-topped bump.

What the doctor may do

Most of these bumps are diagnosed by looking. StatPearls says milia "are diagnosed on clinical findings," and that sebaceous hyperplasia is "diagnosed based on clinical examination or assisted by dermoscopy," a lighted magnifier placed on the skin. Through that magnifier, StatPearls says, sebaceous hyperplasia often shows small blood vessels around the yellow lobules, called "crown vessels." If the doctor is unsure, a skin biopsy, removing a small piece of skin for testing, can settle it. For yellow eyelid patches, the doctor may order a blood fat test.

When to see a doctor

MedlinePlus says to "Contact your provider if you have an unexplained lump or swelling," and that "Most other lumps should be looked at by your health care provider before you try any home treatments." See a doctor, ideally a dermatologist, for any white or pale bump that:

• grows, bleeds, crusts, itches or changes,
• is shiny, pearly or waxy and new in adult life,
• has a dimple in the middle, or spreads to other people,
• sits as a yellow patch on the inner eyelid,
• or that you cannot tell apart from other bumps.

StatPearls says that "when in doubt about the diagnosis, the patient should be referred to dermatology." For confirmed milia, the options are in milia removal, and eyelid bumps are covered in milia under the eyes. White spots on the lips are covered in milia on lips.
