Milia are tiny, firm, white or yellowish cysts that develop when keratin, a natural skin protein, becomes trapped beneath the skin's surface. They commonly appear on the face, especially around the eyes, cheeks, nose, lips, and eyelids, but can occur anywhere on the body. Milia affect people of all ages, from newborns to older adults. Although harmless and painless, persistent or widespread milia may require evaluation and treatment by a dermatologist.

What are the Types of Milia?

Milia are classified based on their cause, age of onset, or associated skin condition.

Neonatal Milia: Common in newborns and usually disappear spontaneously within a few weeks.
Primary Milia: Occur spontaneously in children and adults without prior skin injury.
Secondary Milia: Develop after skin damage caused by burns, blisters, rashes, laser procedures, or other trauma.
Juvenile Milia: Associated with certain inherited disorders such as Bazex-Dupré-Christol syndrome and Gardner syndrome.
Milia en Plaque: Multiple milia occurring on an inflamed or raised plaque, sometimes associated with autoimmune or inflammatory skin disorders.
Multiple Eruptive Milia: Numerous milia that appear suddenly over weeks or months, commonly affecting the face, neck, chest, or upper arms.

What are the Symptoms of Milia?

Milia are usually painless and do not cause inflammation. Their appearance is the primary symptom.

Small white or yellowish bumps measuring about 1-2 mm.
Firm, smooth, pearl-like cysts beneath the skin.
Most commonly found around the eyes, nose, cheeks, lips, or eyelids.
Painless and non-itchy.
No redness or swelling unless irritated.
Usually occur individually or in small clusters.

What Causes Milia?

Milia develop when keratin becomes trapped beneath the skin instead of naturally shedding from the surface.

Natural trapping of keratin beneath the skin.
Sun-damaged skin.
Use of heavy or occlusive skincare products.
Age-related slowing of skin cell turnover.
Skin injuries such as burns, blisters, or rashes.
Laser treatments, dermabrasion, or other cosmetic procedures.
Underlying inherited or inflammatory skin disorders.
Inadequate exfoliation allowing dead skin cells to accumulate.

When Should You See a Doctor for Milia?

Although milia are harmless, medical evaluation is recommended if they persist, become widespread, or develop after skin injury. A dermatologist can confirm the diagnosis and recommend appropriate treatment if needed.

Milia persist for several months without improvement.
Bumps increase in number or size.
Milia develop after burns, blisters, or cosmetic procedures.
Cosmetic concerns affect confidence or quality of life.
The diagnosis is uncertain or the bumps appear unusual.
Milia are associated with other skin abnormalities.

Milia are usually diagnosed and treated by a dermatologist, who can distinguish them from acne, cysts, or other skin conditions.

Professional evaluation helps ensure an accurate diagnosis and prevents unnecessary skin damage from attempting home removal.

How are Milia Diagnosed?

Milia are usually diagnosed based on their characteristic appearance. Additional investigations are rarely required.

Medical history and skin examination.
Assessment of previous skin injuries or cosmetic procedures.
Evaluation to exclude acne, sebaceous hyperplasia, epidermoid cysts, or other skin conditions.
Skin biopsy in rare cases when the diagnosis is uncertain.

What are the Treatment Options for Milia?

Treatment is often unnecessary because many milia resolve spontaneously. Persistent or cosmetically bothersome lesions can be safely removed by a dermatologist.

Observation: Many cases, especially neonatal milia, resolve without treatment.
Topical retinoids: May improve skin cell turnover in selected adults.
Manual extraction: Performed by a dermatologist using a sterile needle or blade.
Cryotherapy: Occasionally used for selected lesions.
Laser therapy: May be considered for persistent or extensive milia.
Chemical peels or gentle professional exfoliation: Can help prevent recurrence in appropriate patients.
Treatment of underlying skin conditions: Particularly for secondary or juvenile milia.
