Milia Diagnosis and Removal in London

Understanding Milia

Milia are epidermal inclusion cysts composed of keratin trapped beneath the stratum corneum. Because they sit under a thin, intact layer of skin, they do not connect to a pore and therefore cannot be squeezed like acne whiteheads. On close inspection, each milium appears as a tiny pearl‑white bead. They most commonly affect the eyelids and peri‑ocular skin, cheeks, nasal sidewalls and upper cheeks, but can occur anywhere—sometimes appearing on the chest, upper arms or genital skin following friction or procedures.

Dermatologists classify milia as primary (arising de novo) and secondary (following triggers such as blistering, burns, resurfacing, radiotherapy, or chronic sun damage). Recognising which pattern you have helps guide treatment and prevention.

Types of Milia

Causes and Risk Factors

Milia develop when keratin—the protein that forms the outer skin—becomes trapped in a small cystic space. Factors that increase the likelihood include:

• Chronic sun exposure: photo‑damaged skin is thicker and less efficient at normal shedding.
• Friction and occlusion: tight eyewear, masks, or heavy occlusive products around the eyes and nose.
• Skin injury or procedures: blistering conditions, burns, dermabrasion or ablative lasers can precipitate secondary milia during healing.
• Genetic or dermatological conditions: association with some blistering disorders or rare genodermatoses.
• Newborn skin maturation: physiologic milia in infants reflects normal cutaneous adaptation.

Good to know: Milia are not caused by poor hygiene and are not infectious or contagious.

How Milia Present

• 1–3 mm, firm, white/yellow papules with a smooth, dome‑shaped surface.
• Frequently peri‑ocular, on the upper cheeks and nasal sidewalls; may appear on the forehead or temples.
• Painless and non‑itchy; do not express pus or “strings” when squeezed.
• Occasionally cluster and catch the light in photos, prompting cosmetic concern.

Diagnosis: Getting the Basics Right

Diagnosis is typically clinical after a focused skin exam. Under magnification or dermoscopy, milia have a uniform, pearly appearance with a subtle white to yellow tone beneath a thin translucent surface. Your dermatologist will also consider differentials that can resemble milia:

• Syringomas: sweat‑duct tumours, often flesh‑coloured and clustered under the eyes.
• Sebaceous hyperplasia: yellowish papules with central indentation (commonly on the forehead).
• Xanthelasma: soft, yellow plaques at inner eyelids (lipid‑related).
• Closed comedones: acne whiteheads that sit within a pore and respond to comedone extraction.
• Favre–Racouchot: solar comedones around the eyes in chronic sun damage (often in smokers).

Rarely, a biopsy is considered for atypical lesions or when a plaque is persistent and diagnosis remains uncertain.

Treatment Options for Milia

Many milia in infants resolve spontaneously and require no treatment. In adults, persistent or cosmetically concerning lesions often need a precise, mechanical solution. We tailor the approach to location, skin tone, and lesion depth to minimise marks and pigment change.

1) Sterile Micro‑lancing & Extraction (Gold Standard)

For most facial milia—particularly around the eyes—micro‑lancing with a sterile, single‑use instrument followed by gentle expression is the safest and most predictable method. We prepare the skin, create a pinpoint opening on the surface, and release the keratin core with fine instruments. On sensitive areas we can use a topical anaesthetic cream. The tiny entry point heals quickly with appropriate aftercare.

• Best for: peri‑ocular milia, scattered facial lesions.
• Downtime: pinpoint redness for 24–72 hours; rare small surface mark that fades.
• Risks: low with expert technique; we avoid vessels and respect natural skin lines.

2) Micro‑Cautery (Electrodessication)

For stubborn or recurring milia, low‑energy micro‑cautery can precisely open the surface and coagulate the cyst lining. We use the lowest effective settings and tiny tips to keep the mark footprint small, especially on thin peri‑ocular skin.

• Best for: resistant lesions; clusters on thicker skin.
• Downtime: small micro‑crusts for 3–7 days; avoid picking; SPF is essential.
• Considerations: careful pigment‑aware parameters for skin of colour to reduce PIH risk.

3) Precision Laser (CO₂/Er:YAG)

Fractional or pinpoint ablative lasers can target resistant milia or plaques (e.g., milia en plaque), vaporising a microscopic column to release the keratin. We stage small areas, particularly near the eyelids, and provide strict aftercare.

• Best for: recalcitrant milia, plaques, or where prior methods were unsuitable.
• Downtime: erythema and micro‑crusting several days; pigment‑aware protocols are mandatory.

4) Topical Retinoids & Skincare Optimisation

Topical retinoids (e.g., tretinoin or adapalene) reduce keratin build‑up and may help prevent new milia, especially in patients prone to recurrence or using heavier eye creams. We build tolerance gradually and adjust for sensitivity. Gentle chemical exfoliants (e.g., low‑strength lactic or mandelic acid) can also smooth texture over time.

• Retinoids are adjuncts, not instant “milia dissolvers”.
• Always pair with moisturiser and daily SPF to protect the barrier.
• We avoid strong actives immediately around the eyelids unless specifically advised.

Aftercare: Healing Cleanly & Predictably

• Cleanse: twice daily with a fragrance‑free, gentle cleanser; pat dry.
• Soothe: thin layer of petrolatum or bland healing ointment for 24–72 hours at treated points.
• Hands off: avoid picking or rubbing; let micro‑crusts shed naturally.
• SPF 30–50 daily: especially for the first 4 weeks to reduce post‑inflammatory pigmentation.
• Actives: pause retinoids/acids for 3–7 days (or as directed) then reintroduce slowly.

Prevention & Skincare Strategy

Skin Tone & Safety Considerations

In skin of colour (Fitzpatrick IV–VI), we take a pigment‑aware approach to reduce post‑inflammatory hyperpigmentation (PIH): conservative energy if using cautery/laser, meticulous aftercare, and strict sun protection. For thin peri‑ocular skin, we favour the smallest effective opening with gentle extraction to keep the footprint minimal.

Common Myths — What Not to Do

• Myth: “If I squeeze harder, it will come out.” — Fact: Milia are not in a pore; squeezing risks bruising and scarring.
• Myth: “A strong scrub will clear them.” — Fact: Abrasion inflames the surface and can worsen texture.
• Myth: “Needling at home is fine.” — Fact: Non‑sterile lancing near the eyes risks infection and permanent marks.

When to Seek Medical Review

• Lesions cluster or enlarge, or new colour change develops.
• Peri‑ocular lesions interfere with makeup/glasses or become irritated.
• You’re unsure whether bumps are milia vs syringomas vs xanthelasma.
• Milia arise after a procedure or burn and persist despite good skincare.

Your First Visit — What to Expect

1. History: skincare, eye products, sun exposure, friction/occlusion, prior procedures and healing pattern.
2. Examination: magnified assessment; we map clusters and identify any differentials.
3. Discussion: options, pros/cons and pigment‑aware safety for your skin tone and location.
4. Procedure: many cases allow same‑day extraction; resistant lesions planned for cautery/laser.
5. Aftercare & prevention: written guidance, product suggestions and follow‑up if needed.
