Crusty eyelids have dried flakes or scales along the lash line. This usually reflects chronic lid margin inflammation or infection.
Main Causes
Blepharitis, seborrhoeic dermatitis, and meibomian gland dysfunction are the most common sources of crusting. Bacterial overgrowth, Demodex mites, and residual make‑up can all contribute to debris on the lashes.
- Patients may notice itching, redness, and a gritty sensation
- Crusts are often worse on waking and may recur without regular cleaning
- Chronic crusting can lead to styes, chalazia, and dry eye symptoms
- Skin conditions such as rosacea and eczema often coexist
Treatment
Daily lid hygiene with appropriate wipes or cleansers is central to managing crusty lids. Additional therapies include warm compresses, lubricants, topical antibiotics, or anti‑inflammatory agents as advised.
- Consistent routine is more effective than occasional treatments
- Replacing old cosmetics and cleaning tools reduces reinfection
- Persistent unilateral crusting or lumps should be evaluated for other lid disease
- Dermatology input may be useful when skin conditions are prominent
