What is the structural difference between milia and other white facial lesions?

Milia are true epidermal keratin cysts that form when keratinocytes become trapped beneath the stratum corneum. Unlike whiteheads or pustules, milia are not connected to hair follicles, sebaceous glands, or pores. They consist of a firm cyst wall enclosing compacted keratin protein, which gives them their characteristic pearl-like appearance and hard texture. This closed, encapsulated structure is what makes milia fundamentally different from acne-related lesions and explains why they do not respond to typical acne treatments.

Why does trapped keratin in milia fail to exfoliate on its own?

Normal skin relies on a regulated process of keratinocyte migration and shedding. In milia, this process is disrupted when keratin becomes isolated beneath an intact epidermal layer, forming a micro-cyst. Because there is no surface opening, exfoliants, acids, and retinoids cannot access or release the trapped keratin. Over time, the cyst wall thickens, further preventing natural resolution and allowing milia to persist for months or even years.

How does CryoPen destroy milia without breaking the skin surface?

CryoPen delivers medical-grade nitrous oxide at extremely low temperatures in a highly focused spray. When applied to milia, rapid freezing causes intracellular ice crystal formation, leading to rupture of keratin-filled cells and collapse of the cyst structure. The surrounding epidermis remains intact because exposure is brief and localised. The damaged keratin is then gradually cleared by the body’s natural skin renewal processes rather than being physically extracted.

Why is squeezing or needling milia medically discouraged?

Because milia lack a pore or follicular opening, squeezing applies pressure to surrounding tissue rather than releasing contents. This often forces keratin deeper into the dermis, triggering inflammation, prolonged redness, and a higher risk of scarring. Improper needling can also disrupt the epidermal barrier, increasing infection risk and post-inflammatory hyperpigmentation—particularly around the eyes where skin is thin and fragile.

How does CryoPen differ from traditional milia lancing techniques?

Traditional lancing mechanically punctures the epidermis to extract keratin, creating a controlled wound. CryoPen, by contrast, relies on cryonecrosis rather than mechanical trauma. This means there is no incision, no bleeding, and minimal disruption to surrounding tissue. The reduced trauma lowers the risk of infection, scarring, and prolonged healing, making CryoPen particularly suitable for cosmetic facial areas.

Why are milia more common around the eyes and upper cheeks?

The periocular and upper cheek regions have thinner epidermal layers, reduced sebaceous activity, and slower cell turnover. These areas are also frequently exposed to occlusive skincare products, sunscreens, and eye creams, which can trap keratin beneath the skin surface. Combined, these factors create an environment where keratin cysts are more likely to form and persist.

Can CryoPen safely treat milia near the eyelid margin?

Yes, when performed by trained professionals. CryoPen’s micro-fine applicator allows clinicians to control both the depth and duration of freezing with extreme precision. This is essential near the eyelids, where underlying structures are delicate. Controlled application ensures the cyst is destroyed while protecting surrounding skin and deeper tissues.

What determines whether milia resolve after one CryoPen session?

Resolution depends on multiple factors including cyst size, keratin density, epidermal thickness, and skin regeneration rate. Superficial milia with loosely compacted keratin often resolve after a single freeze. Larger or denser cysts may require staged treatment to fully collapse the cyst wall without over-freezing surrounding skin.

Why don’t treated milia usually return in the same location?

Once CryoPen destroys the cyst wall and keratin core, the local epidermal architecture does not re-form the same encapsulation. Without a cyst structure, keratin cannot become re-trapped in that location. This makes recurrence at the treated site uncommon when the cyst has been fully destroyed.

Why do some individuals develop new milia over time?

New milia formation is related to individual keratinisation patterns, skin barrier function, sun damage, and skincare habits. People who use heavy, occlusive products or have slower epidermal turnover are more prone to developing new cysts. This reflects an underlying skin tendency rather than failure of previous treatment.

Does CryoPen affect melanin or increase pigmentation risk?

CryoPen acts on keratin-filled cells, not melanocytes. Because it does not use heat or light energy, it avoids stimulating melanin production or causing thermal injury. When applied correctly, the risk of pigmentation changes is very low, making it suitable for delicate facial skin and a range of skin tones.

What post-treatment skin response indicates successful milia removal?

A brief period of redness or a microscopic surface crust may occur, indicating cellular disruption. Over several days, the treated area smooths as the cyst material is absorbed or shed through natural turnover. The skin remains intact, with no open wound, minimal downtime, and a low risk of scarring.

Milia Treatment Ramsgate

CryoPen Treatment for Milia

Milia are small, firm, white or pale bumps that can form just beneath the skin’s surface. They are commonly seen around the cheeks, nose and eye area.

Milia are generally harmless, but some people choose to have them treated for cosmetic reasons.

At Lipo 360, we may offer CryoPen treatment for suitable milia after a consultation and assessment.

What Are Milia?

Milia are small cysts containing keratin, a protein naturally found in the skin.

They can occur in people of different ages and skin types and commonly appear on the face, particularly around the cheeks and eye area.

Milia can sometimes resolve naturally without treatment. However, some may remain for longer periods.

If you have a new, changing, unusual, or undiagnosed skin lesion, we may recommend that you seek assessment from an appropriate healthcare professional before considering cosmetic treatment.

Can Milia Go Away Naturally?

Some milia may disappear naturally over time, so treatment is not always necessary.

If milia persist or you are concerned about their appearance, you can arrange a consultation with Lipo 360 to discuss whether cosmetic treatment may be appropriate.

Trying to squeeze, pick or remove a skin lesion yourself can damage or irritate the surrounding skin.

CryoPen for Milia

Following consultation and assessment, CryoPen may be considered as a treatment option for suitable milia.

CryoPen is a handheld cryotherapy device that delivers a controlled application of nitrous oxide to a targeted area.

The treatment lets the practitioner focus the application on a small treatment area.

Whether CryoPen is appropriate depends on factors including the location and appearance of the milia, your skin, and your medical history.

We will only recommend treatment after an appropriate consultation and assessment.

What Happens During Treatment?

Before treatment, your practitioner will assess the area and discuss whether CryoPen is appropriate for you.

During treatment, the CryoPen applicator is directed towards the targeted area for a controlled period.

Treatment time varies depending on the number, size and location of the areas being treated.

You may experience temporary sensations or skin responses during and following treatment.

Your Lipo 360 practitioner will explain what to expect and provide appropriate aftercare advice.

What Can I Expect After CryoPen Treatment?

The treated area may temporarily change in appearance following cryotherapy.

Possible effects can include:

redness
tenderness or sensitivity
swelling
blistering
crusting or scabbing
temporary changes in skin colour

Pigment changes or scarring may also occur in some cases.

Your practitioner will discuss relevant risks and aftercare with you before treatment.

Do not pick or scratch the treated area while it is healing.

Individual responses and healing times vary.

How Many Treatments Will I Need?

The number of treatments required varies from person to person.

The number of treatments recommended can vary depending on the individual, the area being treated and the response following treatment.

Factors including the number, size, and location of the milia, and your individual skin response, can affect treatment.

Your practitioner will discuss this with you during your consultation.

Results cannot be guaranteed.

Can Milia Come Back?

Treatment of an existing milium does not prevent new milia from developing elsewhere or in the future.

If you are prone to developing milia, you may notice new ones over time.

Lipo 360 cannot guarantee that milia will not recur following treatment.
