Have you noticed tiny white bumps appearing on your face, especially around your eyes or cheeks? These could be milia, small cysts that are quite common and generally harmless. Milia occur when keratin, a protein found in skin, hair, and nails, becomes trapped beneath the skin’s surface, or due to a buildup of dead skin cells. While they often disappear on their own, understanding how to manage and prevent them can be beneficial.
This article will delve into the causes of milia, explore effective at-home and professional treatments, and provide practical tips to prevent their occurrence. We’ll guide you through expert-recommended solutions to help you achieve clearer, smoother skin.
What are Milia?
Milia are characterized as small, raised, white or yellowish bumps typically ranging from 1 to 2 millimeters in size. They are essentially tiny cysts that form just under the outer layer of skin, known as the epidermis. These bumps are filled with keratin, a protein that is a key component of skin structure. Unlike acne or whiteheads, milia are not caused by inflammation or clogged pores in the typical sense. Instead, they arise when dead skin cells don’t naturally shed and become trapped, hardening into these noticeable little cysts.
Milia are frequently found on the face, with a predilection for areas such as the eyelids, cheeks, forehead, and nose. Though less common, they can occasionally appear on other parts of the body. It’s important to distinguish milia from other skin conditions like acne or keratosis pilaris. Milia are not associated with redness or inflammation and are purely a cosmetic concern, not a medical one.
Causes of Milia
Milia develop when the natural exfoliation process of the skin is disrupted, leading to a buildup of keratin. Several factors can contribute to this:
- Trapped Dead Skin Cells: The primary cause is the inability of dead skin cells to shed properly. When these cells remain on the skin surface, they can block pores and hair follicles, trapping keratin underneath.
- Heavy or Occlusive Skincare Products: Certain skincare products, especially those that are very thick or oily, can contribute to milia formation. Heavy eye creams, rich moisturizers, and some types of makeup can create a barrier on the skin, preventing natural exfoliation and trapping dead skin cells.
- Skin Trauma: Milia can sometimes appear after skin trauma, such as minor burns, sun damage, or even after procedures like laser resurfacing. This type is known as secondary milia.
- Certain Medical Conditions: Conditions like eczema or rosacea, and the prolonged use of topical corticosteroids, can also increase the likelihood of developing milia. These conditions can alter the skin’s normal function and shedding process.
- Infant Milia: Milia are very common in newborns, often referred to as “baby acne” or “milk spots,” though they are not related to acne. In infants, milia are thought to occur because their skin is still developing and may not shed dead skin cells as efficiently.
How to Get Rid of Milia
While milia are often self-resolving, especially in infants, adults may find them more persistent. Here are effective strategies for removal, ranging from professional treatments to at-home care:
Professional Treatments (In-office)
For quick and effective removal, especially for persistent milia, professional treatments performed by a dermatologist are recommended.
-
Extraction: This is the most common in-office procedure. A dermatologist uses a sterile needle or blade to create a tiny nick in the skin and then gently extracts the milia cyst. This method is quick, effective, and provides immediate results. It’s crucial to have this done professionally to avoid infection or scarring.
-
Chemical Peels: Chemical peels involve applying a chemical solution to the skin to exfoliate the outer layers. This process can help to remove dead skin cells and uncover milia, as well as improve overall skin texture.
-
Microdermabrasion: This technique uses a special device to gently exfoliate the skin’s surface. By removing the top layer of dead skin cells, microdermabrasion can help to release trapped keratin and reduce milia.
-
Laser Ablation: In some cases, lasers can be used to precisely target and vaporize milia cysts. This is a more advanced treatment option, suitable for widespread or resistant milia.
-
Cryotherapy: This method involves freezing the milia with liquid nitrogen. It’s less common for milia but can be used for various skin lesions.
It is always best to consult with a board-certified dermatologist before undergoing any of these procedures to determine the most appropriate treatment for your specific skin type and condition.
At-Home Treatments and Prevention
While at-home treatments may take longer to show results, they are effective for managing and preventing milia, particularly when incorporated into a consistent skincare routine.
-
Gentle Exfoliation: Regular exfoliation is key to preventing milia by removing dead skin cells. Incorporate products containing alpha-hydroxy acids (AHAs) like glycolic acid or lactic acid, or beta-hydroxy acids (BHAs) like salicylic acid. These acids help to loosen dead skin cells and promote skin cell turnover. Toners, serums, or exfoliating washes containing these ingredients can be beneficial.
-
Retinoids: Topical retinoids, such as adapalene (available over-the-counter in products like Differin Gel) or prescription retinoids, are effective for increasing skin cell turnover and preventing the buildup of dead skin cells. Retinoids help to gently exfoliate the skin and can gradually reduce milia. Start with a low concentration and use sparingly, especially if you have sensitive skin.
-
Warm Compress and Gentle Cleansing: Applying a warm compress to the affected area can help to soften the skin and potentially encourage milia to surface naturally. Gentle cleansing with a mild, non-comedogenic cleanser twice daily helps to keep the skin clean without stripping it of essential moisture.
-
Avoid Heavy Skincare Products: Switch to lighter, non-comedogenic moisturizers, eye creams, and makeup. Look for products labeled “oil-free” or “non-comedogenic,” which are less likely to clog pores and contribute to milia formation.
Best Products for Milia Prevention and Treatment
Here are some recommended over-the-counter products, highlighted in the original article, that dermatologists often suggest for preventing and treating milia:
-
Differin Gel (Adapalene 0.1%): An over-the-counter retinoid that gently exfoliates the skin, preventing clogged pores and promoting cell turnover. It’s effective for both acne and milia. Start using a few times a week and gradually increase frequency as tolerated.
-
La Roche-Posay Effaclar Clarifying Toner: Combines salicylic acid and glycolic acid to exfoliate dead skin cells and prevent milia. It can be used morning and/or night, but those with sensitive skin should start slowly.
-
Skinbetter Science AlphaRet Exfoliating Peel Pads: These pads contain lactic, salicylic, and glycolic acids, along with a retinoid, for effective exfoliation and cell turnover. Use once a week to help prevent milia.
-

Prevention Tips to Avoid Milia
Preventing milia involves consistent skincare habits that promote healthy skin cell turnover and prevent pore-clogging.
- Regular Gentle Exfoliation: Incorporate gentle exfoliation into your weekly skincare routine. This helps prevent the accumulation of dead skin cells that can lead to milia.
- Use Non-Comedogenic Products: Choose skincare and makeup products that are labeled non-comedogenic. These are formulated to not clog pores.
- Lightweight Moisturizers: If you need a moisturizer, especially if you have dry skin, opt for lightweight formulas containing humectants like glycerin or hyaluronic acid, and light occlusives like dimethicone. Avoid heavy oils and butters.
- Sun Protection: Protect your skin from sun damage by using a broad-spectrum sunscreen with SPF 30 or higher daily. Sun damage can contribute to skin texture changes and potentially milia formation.
- Proper Wound Care: If you experience any skin injuries, ensure they are properly cleaned and cared for to promote healthy healing and prevent secondary milia.
When to See a Dermatologist
While milia are generally harmless, it’s advisable to consult a dermatologist in the following situations:
- Persistent Milia: If milia do not resolve on their own after several weeks or months, or if they are widespread.
- Ineffective At-Home Treatments: If over-the-counter treatments are not improving the condition.
- For Extraction: If you prefer quick and effective removal, professional extraction is the safest and most efficient method.
- Diagnostic Uncertainty: If you are unsure whether the bumps are milia or another skin condition, a dermatologist can provide an accurate diagnosis and appropriate advice.
