Milia in Adults: Causes, Persistence, and Treatment Options

Milia are 1–2 mm keratin-filled epidermal cysts, commonly on the face (eyelids, cheeks, forehead). Unlike acne, they lack an opening to the surface.

Why They Persist in Adults

No natural drainage pathway — keratin trapped below stratum corneum.
Adult skin turnover slows; cysts stabilize rather than resolve.
Contributing factors: heavy occlusive creams, sun damage, topical steroids, blistering injuries, genetic predisposition.
Neonatal milia (common, resolve spontaneously) differ from adult primary/secondary milia.

Home Care Limitations

Exfoliation (AHAs/BHAs, retinoids): May prevent new milia; rarely clears existing cysts.
Topical retinoids (tretinoin, adapalene): Increase turnover; modest effect over months.
Heavy creams: Can worsen by increasing occlusion.
Do not squeeze: Causes inflammation, scarring, infection; cyst wall remains.

Professional Removal Methods

Prevention

Lightweight, non-comedogenic moisturizers (gel/serum for eye area).
Daily sunscreen (UV damage → milia).
Gentle retinoid 2–3×/week (long-term).
Avoid chronic topical steroids on face.

When to See a Dermatologist

Numerous or cosmetically bothersome milia.
Eyelid involvement (requires precision).
Uncertain diagnosis (mimics: syringoma, xanthelasma, sebaceous hyperplasia, basal cell carcinoma).
Recurrence after home attempts.

Professional extraction is quick, low-risk, and yields immediate cosmetic improvement.
