When to see a doctor
If you experience severe or worsening symptoms, seek immediate medical attention. Always consult with a healthcare professional for proper diagnosis and treatment.
Causes & Risk Factors
Several factors can contribute to Milia.
Milia form when keratin, a protein found in skin, hair, and nails, becomes trapped beneath the skin's surface.
Milia form when keratin, a protein found in skin, hair, and nails, becomes trapped beneath the skin's surface. Normally, dead skin cells shed naturally through the pores, but sometimes these cells get stuck in small pockets just under the skin. When this happens, the trapped keratin hardens into a small, white cyst.
In newborns, milia develop because their skin is still learning how to shed dead cells effectively.
In newborns, milia develop because their skin is still learning how to shed dead cells effectively. Their oil glands and hair follicles aren't fully mature yet, making it easier for keratin to become trapped. This type is called primary milia and typically appears within the first few weeks of life.
Adult milia can form for several reasons.
Adult milia can form for several reasons. Secondary milia often develop after skin damage from burns, blistering skin conditions, sun damage, or certain cosmetic procedures like dermabrasion or laser resurfacing. Heavy skincare products, particularly thick moisturizers or oil-based cosmetics, can also contribute to milia formation by clogging the skin's natural shedding process. Some people simply have a genetic tendency toward developing these cysts, regardless of their skincare routine.
Risk Factors
- Being a newborn under 4 weeks old
- Having fair or sensitive skin
- Using heavy, oil-based skincare products
- History of blistering skin conditions
- Previous skin trauma or burns
- Excessive sun exposure over time
- Recent cosmetic procedures like dermabrasion
- Family history of milia
- Using thick moisturizers around the eye area
- Certain genetic skin conditions
Diagnosis
How healthcare professionals diagnose Milia:
- 1
Diagnosing milia is usually straightforward and can typically be done through visual examination alone.
Diagnosing milia is usually straightforward and can typically be done through visual examination alone. Dermatologists can often identify milia by their characteristic appearance - small, white, dome-shaped bumps that feel firm to the touch and don't have a visible opening like blackheads or whiteheads.

During the examination, your doctor will look at the size, color, and distribution of the bumps.
During the examination, your doctor will look at the size, color, and distribution of the bumps. They may use a magnifying device called a dermatoscope to get a closer look at the cysts and rule out other conditions. The location of the bumps also helps with diagnosis, as milia have preferred spots like the area around the eyes, cheeks, and nose.

In rare cases where the diagnosis isn't clear, your doctor might perform a small biopsy.
In rare cases where the diagnosis isn't clear, your doctor might perform a small biopsy. This involves removing one of the cysts and examining it under a microscope to confirm it contains keratin. However, this is usually unnecessary since milia have such a distinctive appearance. Your doctor will also ask about your skincare routine, recent procedures, and family history to better understand what might have triggered the milia formation.
Complications
- Milia themselves rarely cause any serious complications since they're essentially harmless cysts.
- The main concern is usually cosmetic, as people may feel self-conscious about the appearance of multiple white bumps on their face.
- In newborns, parents sometimes worry unnecessarily about the bumps, but they pose no health risks.
- The most significant complications typically arise from improper treatment attempts.
- Trying to squeeze or pick at milia can lead to skin infection, scarring, or the formation of larger cysts.
- Some people develop permanent marks or pitted scars from aggressive home removal attempts.
- Professional removal, while generally safe, can occasionally result in temporary redness, minor scarring, or changes in skin pigmentation, especially in people with darker skin tones.
Prevention
- Preventing milia largely comes down to maintaining healthy skin turnover and avoiding products that might clog pores.
- Choose lightweight, non-comedogenic moisturizers and avoid heavy, oil-based products, especially around the delicate eye area where milia commonly form.
- Gentle, regular exfoliation can help keep dead skin cells from building up and becoming trapped.
- Look for products with alpha hydroxy acids like glycolic acid or lactic acid, but use them sparingly to avoid over-irritating your skin.
- Always wear broad-spectrum sunscreen daily, as sun damage can increase your risk of developing milia and other skin problems.
- If you're prone to milia, be extra careful after any skin procedures or injuries.
- Keep the area clean and follow your doctor's aftercare instructions carefully.
- Avoid picking at your skin or using harsh scrubs, which can damage the skin barrier and potentially lead to secondary milia formation.
For newborns, the best treatment for milia is often no treatment at all.
For newborns, the best treatment for milia is often no treatment at all. These cysts typically disappear on their own within 2-4 weeks as the baby's skin matures and learns to shed dead cells more effectively. Parents should avoid trying to squeeze or scrub the bumps, as this can irritate the delicate skin.
For adults who want milia removed, several professional treatment options are available.
For adults who want milia removed, several professional treatment options are available. The most common method is extraction, where a dermatologist uses a sterile needle or small blade to create a tiny opening and gently remove the trapped keratin. This procedure is quick but should only be performed by a trained professional to avoid scarring or infection.
Other effective treatments include cryotherapy, where liquid nitrogen is used to freeze the milia, and electrosurgery, which uses a small electrical current to remove the cysts.

For persistent or widespread milia, topical retinoids may be prescribed to help speed up skin cell turnover and prevent new cysts from forming. Chemical peels containing glycolic acid or other exfoliating agents can also help by removing the top layers of skin.
At-home treatments are limited, but gentle exfoliation with products containing alpha hydroxy acids or beta hydroxy acids may help prevent new milia from forming.
At-home treatments are limited, but gentle exfoliation with products containing alpha hydroxy acids or beta hydroxy acids may help prevent new milia from forming. However, aggressive scrubbing or attempting to pop milia at home often makes the condition worse and can lead to scarring. The key is patience and proper skincare rather than harsh treatments.
Living With Milia
Living with milia is generally straightforward since they don't cause pain, itching, or other uncomfortable symptoms. The main challenge is often cosmetic, particularly when milia appear in prominent areas like around the eyes. Many people find that a good concealer or makeup routine can effectively camouflage the bumps while deciding whether to pursue professional removal.
