Milia are tiny keratin-filled cysts that sit just below the skin surface. A plasma pen can remove them. The pen delivers a focused arc of plasma energy that disrupts the cyst wall from the surface, letting the contents disperse and the skin heal over within two to three weeks. It is gentler than professional needle extraction and does not require squeezing, which does not work on milia because the cyst wall stays intact under pressure.
For a full picture of what at-home plasma pen treatment covers and how the device works, see our complete guide to how plasma pens actually work. This article is the milia-specific answer.
Key takeaways
Yes, a plasma pen works on milia. Here is why squeezing does not, and how to do it at home correctly.
- Milia cysts have a smooth, intact wall. Squeezing compresses the skin but cannot break the wall, so nothing comes out.
- A plasma pen disrupts the cyst wall with plasma energy. The skin heals the treated spot in two to three weeks.
- Use the lowest power setting for the under-eye area. The skin there is the thinnest on the face.
- Retinoids and exfoliating acids can prevent new milia but do not remove existing ones.
- If the bump is changing, bleeding, or you are unsure it is milia, see a dermatologist before treating.
What is milia, and why does it form?
Milia are small cysts, usually one to two millimeters across, that form when dead skin cells and keratin become trapped just below the skin surface. They look like tiny white or skin-colored pearls. They are not pimples, and they are not inflamed. The cyst wall is smooth and intact, which is what makes them different from a whitehead, and what makes squeezing ineffective.
They can appear anywhere on the face. The area under the eyes and across the nose are the most common sites. Milia are not a sign of poor hygiene or an underlying health issue. Per the American Academy of Dermatology, milia are harmless and common across all age groups, including adults who develop them from sun damage, heavy skincare products, or simply as the skin ages and cell turnover slows.
Left alone, milia may stay unchanged for months or years. They do not become dangerous, but they also do not disappear without a method that can open or disrupt the cyst wall.
Does squeezing milia actually work?
No, and the reason is structural. A whitehead (open comedone) has a pore opening at the surface. Pressure releases the contents through that opening. A milia cyst has no surface opening. It is a sealed sac sitting just below the skin. When you squeeze it, you are pressing on the skin around it. The cyst wall does not break under that kind of force. Nothing comes out.
Repeated squeezing bruises the surrounding skin and can leave a dark mark or redness that lasts far longer than the cyst would have. The milia itself sits unchanged underneath. For milia, the wall has to be opened by a method that reaches it directly, either a needle (the clinical approach) or plasma energy (the at-home approach).
How does a plasma pen compare to other milia treatments?
Professional extraction (the clinical standard)
A trained aesthetician or dermatologist uses a sterile needle to pierce the cyst wall, then a comedone extractor to express the keratin contents. It works reliably because it opens the wall directly. Per the Mayo Clinic, professional extraction is the most common clinical approach for milia that have not resolved on their own. The limitation is access and cost: extraction sessions can run several hundred dollars for multiple milia, and not all aestheticians will treat the delicate under-eye area.
At-home plasma pen (the consumer option)
The OcuraLife Plasma Pen delivers a controlled arc of plasma energy to the surface of the milia cyst. The energy disrupts the wall from above without piercing it. A small protective scab forms over Day 3 to 7, the scab falls off on its own, and the treated spot clears over Week 2 to 3. The mechanism is different from needle extraction but the outcome for surface milia is comparable for most users. Nine power settings allow precise, low-energy treatment on sensitive areas like the under-eye.
Retinoids and exfoliating acids (preventive, not removal)
Prescription tretinoin and over-the-counter retinoid products increase cell turnover, which can help prevent new milia from forming and may help some shallow milia resolve slowly over months. They do not remove milia that have already formed. Neither do salicylic acid or glycolic acid products. These are useful skincare tools for other reasons, but they are preventive, not removal methods for existing cysts.
The cyst wall is intact. Anything that does not open it leaves the milia exactly where it is.
How to treat milia with a plasma pen at home
Before you start
Confirm the bump is milia. The checklist: small (one to two millimeters), white or skin-colored, smooth, round, not inflamed, not growing, not bleeding. If the bump is larger, has an irregular border, or you are genuinely unsure what it is, see a dermatologist before treating. The NIH MedlinePlus milia reference describes the clinical appearance in plain language and is a reliable starting point for confirming what you have.
For the under-eye area, start at the lowest power setting your device offers (setting 1 on a nine-setting device). The skin under the eye is the thinnest on the face and reacts to energy settings that would be fine anywhere else.
The treatment itself
Clean and dry the area. Apply numbing cream and wait the full time the product specifies. Set the device to a low setting appropriate for small, surface lesions. Treat each milia with one brief, precise contact. You should see a small change in the surface texture at the spot. Stop immediately after that and move to aftercare. The total treatment per milia is under five minutes, not counting the numbing wait.
Treat a few at a time, not all at once. Let your skin show you how it responds before treating more in the same session. If you have multiple milia, spacing sessions out gives you better feedback on the result before you continue.
Location notes for eyes and nose
Under the eyes: use the lowest power setting, keep the pen tip perpendicular to the skin surface, and use one brief contact per cyst. The area bruises easily. Healing patches between sessions protect the treated spots from friction and keep the area clean.
On the nose: the skin's curvature means the pen tip angle matters more than it does on flat areas. Straighten the contact point before each treatment and use a conservative setting.
Aftercare and the healing timeline
Day 1
Treat and scab forms
A few minutes per milia. A small protective scab appears the same day. Healing patches cover friction points, especially under the eye.
Do not pick the scab. This is the step that causes post-treatment marks. The scab is a seal over new skin forming underneath. Removing it early breaks that process and can leave a mark that takes longer to fade than the milia would have.
Is it safe to treat milia at home?
For confirmed, stable, surface milia, yes, with two conditions met. First, confirm the bump is milia, not something else. Syringomas (small benign sweat-duct growths) look similar and respond to a similar approach, so that look-alike is not a safety concern. But xanthelasma (yellowish deposits near the inner eye) and any bump that is changing, bleeding, or has an irregular border should go to a dermatologist. Second, follow the aftercare. New skin during the Day 3 to Week 3 window is when sun marks happen. SPF 50 through that period is not optional.
When to see a dermatologist instead
See a dermatologist if
- The bump is larger than a few millimeters or growing.
- It bleeds without trauma, or is painful to touch.
- It has an irregular border or uneven color.
- You are not sure whether it is milia or something else.
- It is located at the inner corner of the eye, where the anatomy is too delicate for trial-and-error.
Milia look-alikes include syringomas, xanthelasma, and sebaceous hyperplasia. All are benign, but treatment approaches differ. Treating a xanthelasma with a plasma pen setting appropriate for a one-millimeter milia will undertreat it. Identifying what you have is the step that makes the treatment safe and effective. Per the American Academy of Dermatology, any skin growth that is changing in appearance or behavior should be evaluated by a dermatologist before at-home treatment.

The bottom line
A plasma pen works on milia. It disrupts the cyst wall with plasma energy, the body heals the treated spot over two to three weeks, and the milia is gone. For confirmed, surface milia in accessible locations, it is a reliable at-home option that does not require squeezing (which cannot break the intact wall) and does not need a clinic visit. Start at a low power setting, follow the healing aftercare, and apply SPF 50 through Week 2 to 3. If anything about the bump is changing or you are unsure it is milia, see a dermatologist before treating.
