Milia: Those Tiny White Bumps Explained
Tiny, pearly white bumps appearing around your eyes or cheeks? Chances are you’ve encountered milia, common skin concerns that often cause confusion.
What are Milia?
Milia are small cysts filled with keratin, a protein found naturally in your skin. These cysts form when keratin gets trapped beneath the surface of your skin. Unlike acne or whiteheads, milia aren’t caused by bacteria or inflammation. They’re simply a buildup of trapped keratin that appears as small, white bumps on the skin.
Where Do Milia Appear?
Milia can develop anywhere on the body but are most commonly found:
-
Around the eyes (especially the eyelids)
-
On the cheeks
-
On the nose
-
Around the mouth
Newborns often develop milia, called neonatal milia. These typically disappear within a few weeks without treatment.
Causes of Milia
While the exact cause of milia isn’t always clear, several factors can contribute to their development:
- Dead skin cell buildup: Trapped dead skin cells can lead to keratin accumulating beneath the surface, forming milia.
- Skin damage: Sunburns, harsh skincare products, or skin trauma like blisters can increase the risk of milia formation as the skin heals.
- Certain medications: Some corticosteroids and other drugs might contribute to milia development.
- Use of heavy creams and makeup: Thick skincare products can potentially clog pores and trap keratin.
Treatment Options
Milia are usually harmless and often disappear on their own over time. However, if you’re concerned about their appearance, there are several treatment options available:
- Extraction: A dermatologist can safely remove milia by gently opening the cyst and extracting the keratin plug.
- Topical retinoids: Prescription creams containing retinoid ingredients promote cell turnover and may help prevent milia formation.
- Chemical peels: Superficial chemical peels can exfoliate the skin’s surface, potentially helping to resolve milia.
Preventing Milia
While not always preventable, these tips might reduce your risk:
Exfoliate gently: Regular, gentle exfoliation helps remove dead skin cells and prevent keratin buildup.
Use lightweight skincare: Opt for oil-free and noncomedogenic (won’t clog pores) products.
Sun protection: Protect your skin from sun damage with sunscreen daily.
Are Milia Contagious?
No, milia are not contagious and cannot be spread from person to person.
When to See a Dermatologist:
While most milia are harmless, it’s recommended to consult a dermatologist if:
- You have a large number of milia.
- The milia cause discomfort or irritation.
- Home treatment methods haven’t been effective.
Understanding milia can help you manage this common skin concern effectively and confidently navigate various treatment options available.
What’s the Difference Between Milia and Other Skin Conditions?
It’s easy to confuse milia with other white bumps on the skin, like acne or pearly penile papules. Here’s a quick breakdown:
-
Acne: Acne is caused by inflammation and bacterial infection of hair follicles. Milia are not inflamed or infected.
-
Whiteheads: Whiteheads are a type of acne where a clogged pore is covered by a thin layer of skin. Unlike whiteheads, milia feel smooth and firm to the touch.
-
Pearly penile papules: These small bumps occur only on the corona of the penis (the head). They are completely harmless and unrelated to milia.
Exploring Further
If you’re finding your current skincare routine isn’t preventing milia, consider consulting a dermatologist. They can evaluate your skin type, identify any underlying contributing factors, and recommend personalized solutions for clearer, smoother skin.
Here are some frequently asked questions about milia, based on the information provided in the article:
What are milia?
Milia are small, white bumps caused by trapped keratin (a protein found in skin) under the surface of the skin. They are not inflamed or contagious.
Are milia contagious?
No, milia are not contagious and cannot be spread from person to person.
What causes milia?
Milia can be caused by a buildup of dead skin cells, damage to the skin (like sunburns), certain medications, or heavy skincare products that clog pores.
Where do milia usually appear?
Milia commonly appear around the eyes, cheeks, nose, and mouth.
Do newborns get milia?
Yes, newborns often develop milia called neonatal milia which usually disappear within a few weeks.
How are milia treated?
A dermatologist can remove milia through extraction, prescribe topical retinoids, or suggest chemical peels.
Can I get rid of milia at home?
It is not recommended to attempt to remove milia at home, as this can lead to scarring or infection. Consult a dermatologist for safe and effective treatment.
Can I prevent milia?
You can help reduce your risk by gently exfoliating, using lightweight skincare products, and protecting your skin from sun damage.
What’s the difference between milia and acne?
Milia are not caused by bacteria or inflammation like acne. Milia feel smooth and firm to the touch while whiteheads (a type of acne) are covered by a thin layer of skin.
