FAQ
Frequently Asked Questions
No, xerosis refers specifically to dryness. It can be a symptom of some types of eczema (like atopic dermatitis), but eczema typically involves inflammation, redness, and itching beyond mere dryness.
Yes. Xerosis can refer to dryness of the eyes (xerophthalmia), the mouth (xerostomia), or the vaginal mucous membranes.
It ranges from a mild, common nuisance (like winter-dry skin) to a severe symptom of underlying systemic diseases (like Sjögren's syndrome) or nutritional deficiencies (e.g., Vitamin A deficiency causing xerophthalmia).
Treatment focuses on restoring moisture. This includes using emollients and moisturisers, avoiding harsh soaps and long hot showers, using a humidifier, and in some cases, treating an underlying cause.
