Lamellar Ichthyosis
A rare, severe form requiring intensive daily management. With the right approach, quality of life can be significantly improved. Specialist support is essential.
Autosomal Recessive — both parents must carry the gene mutation. Most common gene: TGM1, but also ABCA12, CYP4F22, ALOX12B, and others.
Large, plate-like, brown or grey scales covering the entire body. Ectropion (eyelid turning outward) common.
Severely reduced sweating (anhidrosis or hypohidrosis). Overheating is a serious risk — especially in summer and during exercise.
Most babies born with a collodion membrane — a tight, shiny, film-like skin. Requires NICU management and resolves over weeks.
Part of the ARCI family
Lamellar Ichthyosis (LI) is classified under Autosomal Recessive Congenital Ichthyosis (ARCI) — a group of rare genetic skin disorders sharing autosomal recessive inheritance and congenital (birth) onset. Understanding which ARCI subtype you have matters for treatment decisions.
Genetic testing (skin biopsy or blood) can confirm your specific subtype and gene. Ask your dermatologist about ARCI specialist referral or see new EDD classification.
Your Daily Routine
Ectropion (eyelids turning outward) is common in lamellar ichthyosis. It exposes the cornea and requires active management:
Scale build-up in the ear canals is a significant problem in lamellar ichthyosis, causing hearing loss and pain if untreated:

Common Problems & Solutions
Reduced sweating is one of the most dangerous aspects of lamellar ichthyosis:
- Cooling vest: Available on prescription in many cases. Essential for hot weather and exercise
- Water mist sprays: Carry at all times in summer. Misting + fan = effective evaporative cooling
- Activity timing: Exercise in the morning or evening, never midday in summer
- Air conditioning: Consider an SSAS grant application for home cooling (ichthyosis qualifies as a qualifying medical condition)
- School/work planning: Employers and schools must provide cooling facilities as reasonable adjustment
- Heat stroke warning signs: Confusion, stopped urinating, hot red skin — call 999 immediately
- Regular eye drops throughout the day (every 2–4 hours minimum)
- Overnight ointment to prevent corneal exposure
- Annual ophthalmology review — do not skip
- Surgical correction available if ectropion is severe — ask ophthalmologist
- Wrap eye gently at night if exposure is occurring during sleep
Lamellar routines can take 1–2 hours daily. Routine fatigue is real and valid. Strategies:
- Listen to podcasts, music, or audiobooks during bath time
- Get a partner, family member, or carer to help with back application
- Simplify morning routine in busy periods (minimum: bath + emollient)
- Claim Disability Living Allowance or PIP — lamellar ichthyosis usually qualifies
- Connect with others via ISG UK support groups — shared experience is powerful
Acitretin is the most effective systemic treatment for lamellar ichthyosis:
- Requires specialist prescription and regular monitoring (liver function, lipids)
- Most common side effect: very dry lips — use Vaseline constantly
- Absolutely contraindicated in pregnancy — stringent contraception required for 3 years after stopping
- Initial "retinoid flare" (skin may look worse for 4–6 weeks before improving)
- Results typically seen 8–16 weeks. Full benefit may take 6 months
- Some patients use intermittent therapy (9 months on, 3 months off)
8-Week Management Protocol
Establish the intensive routine
Buy: Epaderm 500g ×4, Oilatum Plus bath additive, urea 40% cream, eye drops, soft bath loofah mitt, cooling spray bottle.
Goal: Morning AND evening routine. Aim for minimum 20-minute soaks twice daily.
Optimise scale removal technique
Experiment with the order: keratolytic first vs emollient first vs alternating. Log results. Most find keratolytic first on damp skin works best.
Temperature management plan
Create a heat plan for summer (or next warm period). Research cooling vest options. Apply for PIP/DLA if not already claiming.
Specialist review
Discuss acitretin with your dermatologist if not already on systemic treatment and topicals are insufficient. Review eye and ear care plans.
Refine and maintain
If starting acitretin: weeks 5–8 are when early benefits may begin to appear. Maintain topical routine alongside systemic treatment. Full medication guide →
Community Tips
"I listen to an audiobook for my entire evening routine. The bath plus application takes 90 minutes and I just zone out into the story. Changed my relationship with the routine completely."
— Rebecca, 32, Lamellar
"A cooling vest was life-changing for my daughter. She can now go to school in summer without the fear of overheating. Ask your dermatologist about a prescription."
— Parent of a child with lamellar
"50:50 paraffin mix from the pharmacy is so much cheaper than branded emollients and just as effective. Ask your GP to prescribe it by name."
— David, 29
Red Flags
- Signs of heat stroke: confusion, hot dry red skin, stopped sweating, high temperature over 40°C
- Severe skin infection with fever and spreading redness
- Corneal injury — sudden pain, photophobia, vision loss
- Breathing difficulty if scales restrict chest movement
- New or spreading skin infection
- Ectropion worsening or corneal pain
- Significant ear canal blockage causing hearing loss
- Routine is taking more than 2 hours with no improvement
