These bumps are usually quite small—about one to three millimeters—and often begin to appear during adolescence. They tend to occur more frequently in women. The condition arises from an overgrowth of cells within the sweat glands, which are responsible for regulating body temperature by releasing sweat.
This overgrowth can be triggered by a variety of factors, including genetics, physical activity, heat, stress, or underlying health conditions. Because syringomas can resemble other skin issues—such as xanthelasma (cholesterol deposits), trichoepitheliomas, or even basal cell carcinoma—it’s important to consult a healthcare provider for an accurate diagnosis. Treatment options like laser therapy or electrosurgery are available, though results may vary, and minor scarring is possible.
Molluscum contagiosum: Viral skin infections
Molluscum contagiosum is a viral skin infection that causes small, wart-like bumps. These growths are typically pink, skin-toned, or light brown and often feature a tiny indentation in the center. While generally harmless, they can sometimes cause itching or lead to redness and irritation in the surrounding skin.
This condition is contagious and spreads through direct skin-to-skin contact or by sharing personal items such as towels, clothing, or bedding. Although molluscum is most commonly seen in children, adults can develop it as well. The bumps usually clear up on their own over time, though the process can take several months to a few years.
For those who prefer quicker results, dermatological treatments are available. Options may include topical medications like cantharidin, cryotherapy (freezing), or gentle extraction by a medical professional.
Millia: Tiny white cysts under the skin.
If you notice small, white, smooth bumps on your face that don’t seem to disappear, they could be milia.
These tiny cysts commonly show up in clusters on areas like the cheeks, nose, or around the eyes. As explained by Dr. Carmen Castilla, a board-certified dermatologist in New York City, milia form when dead skin cells become trapped beneath the skin’s surface.
Milia can develop due to skin trauma, the use of heavy skincare products that block pores, prolonged sun exposure, or certain inherited conditions. To reduce the risk, avoid harsh rubbing and opt for lightweight, non-comedogenic products instead of thick creams. Mild chemical exfoliants may also help keep your skin clear.
If the bumps persist, a dermatologist can safely remove them.
Sebaceous Cysts: Slow-growing bump under the skin.
Sebaceous cysts are harmless, slow-developing lumps that form beneath the skin. They commonly appear on areas like the scalp, face, ears, back, chest, or groin.
These cysts may arise from a ruptured hair follicle, a poorly formed duct, an injury, or sometimes with no obvious cause. They are typically filled with a combination of keratin, oil, and dead skin cells. Unlike sebaceous hyperplasia, which feels more fixed to the skin, sebaceous cysts usually move slightly when pressed, often resembling the feel of a small, soft water balloon.
They might remain unchanged in size, gradually enlarge, or become irritated, inflamed, or even burst, increasing the risk of infection. In many cases, treatment isn’t necessary unless the cyst becomes uncomfortable, painful, or infected. If needed, medical care may involve drainage, steroid injections, antibiotics, or surgical removal to prevent recurrence.
Xanthelasma: Cholesterol deposits near the eyes.
Xanthelasma appears as pale yellow or white patches or bumps near the eyes, most often on the eyelids. These formations are typically flat and uneven, setting them apart from the small, raised shape of milia. These bumps are composed of cholesterol deposits beneath the skin, and individuals with xanthelasma often have elevated cholesterol levels.
Although relatively uncommon, xanthelasma does not go away on its own. While the condition isn’t dangerous, many people choose to have the patches removed for cosmetic reasons. Treatment options include surgical excision, laser therapy, or cryotherapy (freezing).
If you notice these types of bumps, it’s encouraged to consult a healthcare provider, as they may indicate an underlying issue such as high cholesterol or other health concerns.
Keratosis pilaris: Rough, bumpy skin.
Keratosis pilaris is a common skin condition that leads to small, rough bumps that may appear red, purple, or match your natural skin tone. Often nicknamed “chicken skin” because of how it looks and feels, this condition typically shows up on the upper arms or thighs, though it can also affect the cheeks.
The exact cause isn’t fully understood, but it often runs in families and is more likely to appear in people with eczema. While it’s harmless and tends to improve over time, you can manage its texture with regular use of exfoliating and hydrating creams.
How to tell the difference between acne and other skin bumps and when to see a dermatologist?
This guide may help you recognize and understand an unfamiliar bump on your skin.
If you notice a red bump on your face, it’s helpful to determine whether it’s acne or something else. Acne typically appears with other signs like blackheads, whiteheads, or additional pimples. These blemishes may contain pus, feel tender, especially if they’re inflamed, and often last for a few weeks.
In contrast, many other skin bumps are painless, appear alone, and don’t come with surrounding breakouts. If you have a persistent bump that isn’t going away and you’re unsure what it is, it’s encouraged to consult a doctor or dermatologist. Medical attention is especially important if the bump bleeds and doesn’t heal, changes in size or color, becomes an open sore, spreads rapidly, or causes discomfort such as itching or pain.
Most white bumps on the face, like clogged pores or milia, are generally harmless and may not require treatment. However, because some bumps could indicate more serious conditions, getting a professional evaluation is the best way to ensure proper care and peace of mind.
