Milia are not pimples, and they do not “pop” the way a whitehead does. They are tiny cysts filled with hardened keratin protein, not liquid pus, so squeezing alone rarely works and often leaves a mark. The safe removal technique involves creating a small opening in the skin over the cyst and then gently coaxing the solid plug out. Done correctly with the right tools, the process carries very little scarring risk because milia sit just beneath the skin surface. Done carelessly, though, you can end up with a red or pitted scar that lasts far longer than the bump itself would have.
Why Milia Do Not Behave Like Pimples
Understanding what you are actually dealing with changes how you approach removal. Milia are small, benign, superficial keratinous cysts, typically under 3 millimeters across, that form when dead skin cells become trapped just below the surface instead of shedding normally.1Egyptian Journal of Dermatology and Venereology. Acne mimickers They look like tiny white or yellowish beads embedded in the skin, most commonly around the eyes, nose, and cheeks. Unlike acne, there is no bacterial infection, no inflammation, and no fluid to drain. The contents are a firm ball of keratin, the same protein that makes up your hair and nails.
This is why simply pressing on a milium from both sides, the way you might squeeze a blackhead, almost never works. There is no pore opening for the material to exit through. The skin over a milium is intact, so pressure just pushes on the surrounding tissue, bruising it or tearing it unevenly. That torn, inflamed skin is where scarring starts.
The Extraction Technique That Minimizes Scarring
The principle behind safe milia removal is straightforward: you create one small, controlled opening in the thin layer of skin covering the cyst, then ease the keratin plug out through that opening. Dermatologists call this de-roofing. A published case series described using a blood glucose testing lancet to puncture the overlying skin and a bent paper clip to express the contents, demonstrating that milia extraction does not require expensive equipment when the technique itself is clean and precise.2Cutis. Blood Glucose Testing Lancet and Paper Clip as a Milia Extractor
If you attempt this at home, the steps that matter most for avoiding scarring are:
- Sterilize everything: A sterile needle, lancet, or diabetic lancet pen is essential. Wiping a sewing needle with rubbing alcohol is better than nothing, but a sealed, single-use lancet is cheap and meaningfully safer.
- Work under good light: You need to see exactly where the milium sits so your puncture goes through the thinnest point of skin directly over the cyst, not to one side of it.
- Pierce only the surface: The goal is a tiny nick in the very top layer of skin, just enough to break the seal. You are not digging. If you feel resistance, you have gone deep enough.
- Express gently: Using a comedone extractor, the looped end of a bent paper clip, or even two cotton-tipped swabs, apply light sideways pressure around the opening. The keratin bead should ease out. If it does not come with gentle pressure, stop. Forcing it is what causes scarring.
The puncture itself, when done correctly, is so shallow that it heals within a day or two with minimal to no visible mark. Problems arise when people dig deeper trying to reach the cyst, use dirty tools, or squeeze so hard that they rupture capillaries and damage the surrounding dermis.
The Biggest Mistakes People Make
The most common mistake is treating milia like acne and just squeezing without creating an opening first. Because the skin over a milium is sealed, brute-force pressure tears the tissue unpredictably. Instead of a clean, tiny puncture, you get a jagged wound that takes longer to heal and is more likely to leave a mark. The area around the eyes is especially unforgiving here because the skin is thinner and more prone to visible scarring.
Another frequent error is attempting removal on bumps that are not milia at all. Milia look similar to closed comedones, sebaceous hyperplasia, and syringomas, but each of these has a different structure beneath the surface.1Egyptian Journal of Dermatology and Venereology. Acne mimickers Syringomas, for example, are benign sweat duct tumors. Trying to extract one as though it were a milium will not work and can cause a wound that scars. If a bump does not yield a small, solid white bead when you gently express it, stop immediately. It is probably not a milium.
Using fingernails instead of proper tools is another problem. Nails harbor bacteria, apply uneven pressure, and often gouge the skin. Even if you manage to get the milium out, the crescent-shaped nail marks can leave hyperpigmentation or small scars, especially on darker skin tones.
When to Leave It to a Professional
A single milium on your cheek in a well-lit bathroom is one thing. But there are situations where self-extraction carries meaningfully higher scarring risk and a dermatologist is the better choice.
Milia clustered around the eyelids or directly on the eyelid margin are the clearest case for professional treatment. The skin there is extraordinarily thin, and even a small mistake can cause visible scarring or irritation to the eye. For these, dermatologists sometimes use an erbium:YAG laser, which ablates tissue with very precise control and minimal thermal damage to surrounding skin. A published case of periocular milia treated this way showed nearly complete resolution with no scarring, no pigment changes, and no eye complications.3PubMed.

Multiple milia spread across a larger area, sometimes called milia en plaque, also warrant professional care. Trying to lance and extract a dozen or more cysts yourself increases the cumulative risk of infection and uneven healing. A dermatologist can work through them efficiently in a single visit with consistent technique and sterile conditions.
If you have a history of keloid or hypertrophic scarring, any skin puncture carries elevated risk. People who scar easily should have even straightforward milia removed professionally, where the provider can control the wound size precisely and advise on aftercare tailored to scar-prone skin.
Professional Treatment Options Beyond Manual Extraction
Manual extraction with a sterile needle or lancet is the most common professional method and what most dermatology offices will do first. The technique is essentially the same as what was described above, just performed with better tools, sterile conditions, magnification, and trained hands. For the majority of milia, this is all that is needed.
Laser ablation is a step up, reserved mainly for milia in delicate areas or cases where many bumps need to be addressed at once. The erbium:YAG laser is favored for this because it removes tissue in very thin, controlled layers and produces minimal heat damage to the skin around the treatment site.3PubMed. Periocular milia en plaque successfully treated by erbium:YAG laser ablation This precision is what makes it suitable for areas like the eyelids, where even a fraction of a millimeter of unnecessary damage matters.
Electrodesiccation, where a tiny electric current destroys the cyst, is another option some dermatologists use. It works well but carries a slightly higher risk of post-treatment pigment changes on darker skin, so it is not always the first choice. Cryotherapy, or freezing with liquid nitrogen, is occasionally mentioned for milia, but it is less precise than other methods and more likely to leave temporary discoloration.
Aftercare That Protects Against Scarring
How you treat the skin after extraction matters almost as much as the extraction itself. Basic skin care after any minor invasive procedure supports the skin barrier, controls inflammation, and promotes clean healing.4Dovepress / PubMed Central. Skin Care Management For Medical And Aesthetic Procedures To Prevent Scarring For milia extraction, aftercare does not need to be complicated, but a few steps are worth following consistently.
Immediately after extraction, apply a thin layer of a plain, fragrance-free occlusive like petroleum jelly or an antibiotic ointment to the puncture site. This keeps the wound moist. Contrary to the old instinct of “letting it air out,” moist wound healing produces less scarring than allowing a wound to dry and scab. A small adhesive bandage over the area for the first day keeps the ointment in place and prevents you from touching the spot.
For the following week or so, keep the area clean with a gentle cleanser and reapply the occlusive once or twice daily until the puncture has fully closed. Avoid applying active skincare ingredients, particularly retinoids, glycolic acid, or vitamin C serums, directly over the healing site. These can irritate the fresh wound and slow healing.
Sun protection is the aftercare step people most often skip, and it is the one that matters most for preventing post-inflammatory hyperpigmentation. New skin at a healing wound site is more susceptible to UV damage, and sun exposure on that spot can leave a dark mark that persists for months, especially on medium to dark skin tones. Apply a broad-spectrum sunscreen daily, or cover the area with a small bandage if it is in a conspicuous spot.
Can You Prevent Milia From Forming in the First Place
Milia are common enough that some people seem to get them no matter what they do, and the underlying tendency may be partly genetic. That said, certain skincare habits are associated with fewer milia over time.
Regular gentle exfoliation helps dead skin cells shed before they can become trapped. A mild chemical exfoliant containing a low concentration of a beta hydroxy acid or an alpha hydroxy acid, used a few times per week, can keep the skin surface turning over. Physical scrubs work too, but the abrasive ones can irritate the delicate facial skin where milia tend to appear, so a washcloth or a very fine-textured scrub is preferable to anything with large, rough particles.
Heavy, occlusive skincare products and thick sunscreens are sometimes linked to milia formation, especially around the eyes. If you notice milia appearing in areas where you apply a particularly rich eye cream or a dense mineral sunscreen, it is worth switching to a lighter formulation. This does not mean avoiding moisturizer or sun protection, just choosing products that are less likely to trap dead skin cells beneath the surface.
Topical retinoids, prescribed or over-the-counter retinol, promote skin cell turnover and are sometimes recommended by dermatologists for people who get recurrent milia. They are not a quick fix; retinoids take weeks to months to show effects, and they can cause irritation early on. But for someone dealing with milia repeatedly, they address the underlying cell-turnover issue rather than just treating bumps one at a time.
Milia in Newborns and Children
About half of all newborns develop milia, often called Epstein pearls when they appear on the gums or roof of the mouth. These neonatal milia are completely benign and almost always resolve on their own within a few weeks to a couple of months. No extraction is needed, and parents should not attempt to pop or scrub them away. The baby’s skin is still maturing, and any intervention carries more risk of irritation and scarring than simply waiting.
Older children occasionally develop milia too, sometimes after a sunburn, a mild skin injury, or use of a topical steroid. The same leave-it-alone approach applies in most cases, since children’s skin heals quickly and milia at this age tend to be temporary. If a milium persists for several months and bothers the child, a pediatric dermatologist can remove it safely, but home extraction on a child’s skin is best avoided.
Secondary Milia After Skin Injuries
Primary milia, the kind that appear spontaneously on otherwise healthy skin, are the ones most people are asking about removing. But milia can also develop as a secondary response to skin damage. Burns, blistering conditions, dermabrasion, and laser resurfacing can all trigger milia formation during the healing process. These secondary milia appear in the damaged area as the skin rebuilds, and they can be more stubborn than the primary type.
If you develop milia after a cosmetic procedure or an injury, mention it to your dermatologist rather than extracting them yourself. The underlying skin in those areas may still be healing, and puncturing it prematurely can interfere with recovery and increase scarring risk. In most cases, secondary milia clear as the skin finishes remodeling, though a few may need extraction once the area is fully healed.
What Milia Are Not
People sometimes confuse milia with other small white or flesh-colored facial bumps and try to extract them using the same technique. This rarely ends well. Sebaceous hyperplasia, an overgrowth of oil glands that produces yellowish bumps with a central dimple, will not yield a keratin plug no matter how precisely you lance it. Syringomas, those firm flesh-colored bumps that cluster below the eyes, are embedded deeper in the skin and cannot be extracted through a surface puncture. Closed comedones, the bumps most often confused with milia, are technically part of the acne family and contain a mix of sebum and dead skin cells rather than a solid keratin bead; they respond to different treatments.
The practical takeaway is that if you puncture a bump and nothing solid comes out easily, or if a clear or oily fluid appears instead of a white bead, you are dealing with something other than a milium. Stop, clean the area, and let it heal. Continuing to dig around will almost certainly leave a scar, and whatever the bump is, a dermatologist can identify and treat it more appropriately.
Skin Tone and Scarring Risk
Scarring risk from milia extraction is not uniform across all skin types. People with darker skin tones are more prone to post-inflammatory hyperpigmentation, where a healing wound leaves a dark spot that can last months or even years. The extraction itself may heal perfectly in terms of texture, but the color change can be cosmetically bothersome and is sometimes mistaken for a scar.
For this reason, aftercare is especially important on melanin-rich skin. Diligent sun protection, gentle wound care, and avoiding picking at the healing site all reduce the risk of lasting pigment changes. Some dermatologists recommend a short course of a topical brightening agent like azelaic acid once the puncture has fully closed, to prevent or treat any hyperpigmentation that does develop. If you know your skin tends to darken at wound sites, having a professional perform the extraction in a controlled setting gives you the best odds of an invisible result.
