A doctor can often make a diagnosis by examining the affected skin and the characteristic scales. He or she may perform other tests, such as a skin biopsy. This may be necessary to rule out other causes of dry, scaly skin.
Ichthyosis vulgaris doesn't have a known cure, so the goal of treatment is to manage the condition.
Treatments may include:
- Exfoliating creams and ointments. Prescription creams and ointments containing alpha hydroxy acids, such as lactic acid and glycolic acid, help control scaling and increase skin moisture.
Oral medication. Your doctor may prescribe vitamin A-derived medications called retinoids to reduce the production of skin cells. Side effects from the medication may include eye and lip inflammation, bone spurs and hair loss.
Retinoids may cause birth defects. Women considering retinoid therapy should be sure they are not pregnant before starting the medication — and use effective birth control while taking retinoids.
Lifestyle and home remedies
Self-help measures may help improve the appearance and feel of damaged skin. Consider these suggestions:
- Take long soaking baths to soften the skin. Use mild soap. Rub dampened skin lightly with a rough-textured sponge (loofa) or a pumice stone to help remove the scales.
- After showering or bathing, gently pat or blot the skin dry with a towel so that some moisture remains on the skin.
- Apply moisturizer or lubricating cream while the skin is still moist from bathing. Choose a moisturizer with urea or propylene glycol — chemicals that help keep skin moist. Petroleum jelly is another good choice.
- Apply an over-the-counter product that contains urea, lactic acid or a low concentration of salicylic acid twice daily. Mild acidic compounds help skin shed its dead skin cells. Urea helps bind moisture to skin.
- Use a portable home humidifier or one attached to your furnace to add moisture to the air inside your home.
Preparing for your appointment
If the appointment is for your child, you're likely to start by seeing your child's pediatrician. If the appointment is for you, you're likely to start by seeing your primary care doctor. He or she may refer you or your child to a specialist in skin conditions (dermatologist).
Here's some information to help you prepare for the appointment.
What you can do
Before your appointment make a list of:
- Any symptoms your child or you are experiencing, including any that may seem unrelated to the reason for which you scheduled the appointment.
- Key personal information, including any major stresses or recent life changes.
- All medications, vitamins or supplements your child or you are taking.
- Questions to ask your doctor.
For ichthyosis vulgaris, some basic questions to ask your doctor include:
- What's the most likely cause of my symptoms?
- Are there other possible causes?
- What kinds of tests will I or my child need?
- Is the condition likely temporary or long lasting?
- What treatments are available and which do you recommend?
- Do you have any brochures or other printed materials I can take with me? What websites do you recommend?
What to expect from your doctor
Your doctor is likely to ask you a number of questions, including:
- When did the symptoms first appear?
- Are the symptoms constant or do they come and go?
- Does anything help improve the symptoms?
- What, if anything, makes the symptoms worse?
- Does anyone in your family have similar skin changes?
What you can do in the meantime
To help soothe affected skin:
- Wash only with mild soaps that have added oils and fats. Avoid strongly scented and antibacterial soaps, which may be too harsh on dry skin.
- Apply moisturizer or lubricating cream while the skin is still moist from bathing. Choose a moisturizer such as petroleum jelly or one that contains urea or propylene glycol — chemicals that help keep skin moist.
