Stubborn White Bumps? Why Milia Won't Pop and Your Medical Next Steps

If you've ever noticed tiny, hard white bumps on your skin that simply won't pop, you're likely dealing with milia. These small cysts are common, harmless in most cases, and often mistaken for whiteheads. But unlike acne, milia don't behave the same way — and trying to squeeze them can make things worse.

Let's break down what milia are, why they won't pop, and what your safest next steps should be.

What Is Milia?

Milia (singular: milium) are small, firm, white or yellowish bumps that form when keratin — a protein found in skin — becomes trapped beneath the surface. They typically measure 1–2 millimeters in size.

They most commonly appear:

• Around the eyes
• On the cheeks
• On the forehead
• On the nose
• On the chest

Milia affect both adults and children, and they are extremely common in newborns.

Why Milia Won't Pop

This is the most important thing to understand: milia are not pimples.

Unlike acne:

• Milia do not contain pus.
• They are not caused by clogged pores filled with oil.
• They sit deeper under the skin.
• They are covered by a firm layer of skin.

When you try to squeeze milia:

• Nothing comes out.
• You may damage the surrounding skin.
• You increase your risk of scarring.
• You may introduce infection.

Because milia are tiny cysts enclosed in a small sac under the skin, they usually need professional removal if they don't go away on their own.

Types of Milia

There are several forms of milia. Knowing the type helps determine whether treatment is necessary.

1. Primary Milia

• Form spontaneously
• Common around eyelids and cheeks
• Seen in both children and adults

2. Secondary Milia

• Develop after skin injury
• Can follow burns, blisters, rashes, or cosmetic procedures
• May appear after long-term use of heavy steroid creams

3. Neonatal Milia

• Found in up to half of newborns
• Usually resolve within a few weeks
• Do not require treatment

4. Multiple Eruptive Milia

• Appear in clusters
• May be associated with genetic conditions
• Less common

Most adult milia are harmless and cosmetic, but persistent or widespread cases deserve medical attention.

What Causes Milia?

While milia can appear without a clear cause, common triggers include:

• Sun damage (thickened skin traps keratin)
• Heavy skincare products
• Oil-based creams
• Poor exfoliation
• Skin trauma
• Aging skin
• Certain medications

In some cases, milia may signal an underlying skin disorder, especially if they are widespread or recurring.

Should You Be Concerned?

In most cases, milia are benign and not dangerous. They are a cosmetic issue rather than a medical threat.

However, you should speak to a doctor if:

• The bumps change in size, color, or shape
• They become painful
• They are spreading rapidly
• They appear after an injury and don't improve
• You are unsure whether they are milia or another condition

Other skin conditions can mimic milia, including:

• Basal cell carcinoma
• Sebaceous hyperplasia
• Syringomas
• Closed comedones

While rare, certain skin cancers can look like persistent white bumps. That's why a proper diagnosis matters.

How to Safely Treat Milia

1. Leave Them Alone (Sometimes Best)

Many cases of milia resolve on their own over weeks to months. This is especially true for newborns and mild adult cases.

Avoid:

• Picking
• Squeezing
• Scrubbing aggressively

2. Gentle Exfoliation

Mild exfoliation can help prevent new milia from forming by removing dead skin cells.

Look for:

• Salicylic acid
• Glycolic acid
• Retinoids (if tolerated)

Start slowly. Over-exfoliating can irritate skin and worsen the problem.

3. Professional Extraction

If milia persist, a dermatologist can remove them safely.

Medical removal typically involves:

• Using a sterile needle to open the surface
• Gently extracting the trapped keratin
• Minimal discomfort
• Low risk of scarring when done correctly

This is a quick in-office procedure.

4. Prescription Retinoids

For recurring milia, a doctor may prescribe topical retinoids. These:

• Increase cell turnover
• Reduce buildup of keratin
• Help prevent new cyst formation

They are not suitable for everyone and may cause irritation, especially around the eyes.

5. Chemical Peels or Laser Therapy

For multiple or stubborn milia, dermatologists may recommend:

• Light chemical peels
• Laser resurfacing
• Microdermabrasion

These treatments help thin the outer layer of skin and prevent recurrence.

What NOT to Do

Avoid common mistakes that can worsen milia:

• Do not use sharp tools at home.
• Do not attempt to "dig them out."
• Do not use harsh scrubs.
• Do not apply heavy, oily creams around the eyes.

DIY removal often leads to:

• Scarring
• Infection
• Dark spots
• Prolonged redness

Preventing Milia

While not always preventable, you can reduce your risk by:

• Using non-comedogenic skincare products
• Removing makeup thoroughly
• Wearing sunscreen daily
• Avoiding thick eye creams if prone to milia
• Exfoliating gently 1–2 times per week
• Avoiding long-term use of heavy steroid creams unless medically necessary

Consistency matters more than aggressive treatment.

When to Speak to a Doctor

Most milia are harmless, but medical evaluation is important if:

• The bumps bleed or crust
• They grow larger
• They persist for many months
• They appear alongside other symptoms
• You have a history of skin cancer

Any skin change that concerns you should be evaluated. While milia themselves are not life-threatening, misdiagnosing a more serious condition can delay needed treatment.

If you notice warning signs such as rapid growth, ulceration, or color change, speak to a doctor promptly.

The Bottom Line

Milia are stubborn because they are not pimples. They are tiny cysts trapped beneath the skin, which is why they won't pop — and why trying to force them can cause harm.

The good news:

• They are usually harmless.
• They are common.
• They are treatable.
• They often resolve on their own.

If you're concerned about those white bumps on your skin, start by using a free Milia symptom checker to understand your symptoms better and get guidance on whether you need to see a healthcare provider.

And remember: while most milia are cosmetic, any persistent, changing, or unusual skin lesion should be evaluated by a healthcare professional. When in doubt, speak to a doctor to rule out anything serious and to discuss the safest treatment options for your skin.

Taking a cautious, informed approach protects both your skin and your health.
