Xerosis cutis is the medical word for very dry skin. It sounds serious, but for many people it simply means skin that has lost moisture and feels rough, tight or flaky. Gentle daily habits are the usual first step, and a doctor can help when the dryness is severe or does not go away.
This guide explains what the term means, what can cause it, how people care for it and when to ask for help. Please read it as general information only, not as medical advice.

What is xerosis cutis?
Cleveland Clinic explains that dry skin is skin without enough moisture to keep it soft, and that the medical term is xeroderma. It says xerosis refers to severely dry skin (page last updated 23 June 2022).
In other words, xerosis cutis is not a separate disease for most people. It is a description of how the skin looks and feels, and it can be mild or severe. If you want the everyday version of the topic, our guide to what causes dry skin covers the common triggers in plain language.
What does xerosis cutis look like?
Cleveland Clinic says dry skin may be cracked, rough, tight, flaking, scaly or itchy, and that it may look lighter, darker, or red to purple depending on skin tone. Severe dryness can lead to a rash called dermatitis, with small bumps, itching or swelling.
The same page lists the hands, feet, face, elbows, the area around the mouth, the genitals and the legs as common places to see it. For help with one of those spots, see our guides to dry feet and dry elbows.
What causes xerosis cutis?
Cleveland Clinic lists several causes and risk factors, which the table sums up.
| Cause or risk factor | What the source says |
|---|---|
| — | — |
| Age | Moisture-producing oil glands decline and skin thins over time; people aged 65 or older are at higher risk |
| Climate | Low-humidity, desert-like, or cold, windy places can dry the skin |
| Health conditions and genetics | Allergies, eczema, diabetes and kidney disease can contribute |
| Work and habits | Outdoor work, chemical exposure and frequent hand washing, common in healthcare, hairstyling and farming |

Hot water and strong soaps also strip natural oils. The American Academy of Dermatology (AAD) says harsh soaps, including deodorant soaps, can irritate dry skin (updated 2 January 2026).
How is xerosis cutis cared for at home?
Cleveland Clinic calls moisturizers the main treatment for dry skin. It suggests products without fragrance or drying alcohols, and with ingredients that lock in or attract moisture. It also gives a simple schedule: apply moisturizer when you wake up, before bed, and after bathing while the skin is still damp.
The AAD agrees on timing and adds that creams and ointments add more moisture than lotions. It lists glycerin, hyaluronic acid, lactic acid, dimethicone, petrolatum, shea butter, lanolin, jojoba oil and mineral oil among helpful ingredients, and says to avoid alcohol, fragrance and retinoids on dry skin. Our body lotion for dry skin guide shows how to read a label.
How should you bathe with xerosis cutis?
Short, warm baths protect the skin. Cleveland Clinic advises warm rather than hot water, a mild fragrance-free cleanser that is not soap, and patting the skin dry with a soft towel. The AAD gives a time limit of five to ten minutes in warm water, and suggests using a gentle cleanser in small amounts and only where you need it.
Both sources also point to the air around you. Cleveland Clinic suggests considering a humidifier, limiting sun exposure and staying hydrated. The AAD says a portable humidifier in the bedroom can help while you sleep, as long as it is cleaned regularly to prevent mold.
Can xerosis cutis be a sign of something else?
Sometimes. Cleveland Clinic names allergies, eczema, diabetes and kidney disease as conditions that can contribute to dry skin, and the AAD says persistent dry skin can signal conditions such as atopic dermatitis, psoriasis or kidney disease. Dry skin on its own does not tell you which of these, if any, is behind it.
That is why lasting dryness deserves a check, not a guess. Our dry skin treatment guide explains what general care can and cannot do.
When should you see a doctor about xerosis cutis?
Cleveland Clinic advises contacting a provider if:
- Itching is constant and disrupts your sleep or daily activities.
- The skin looks infected, or is red, warm or swollen.
- The skin is painful to touch, or a rash develops.
- The dryness does not go away or keeps returning.
The page adds that severe cases may need a prescribed topical steroid, or oral or injectable medication, which only a clinician can decide. The AAD makes the same point for persistent dryness, advising a visit to a board-certified dermatologist.
Is xerosis cutis the same as dry skin?
For most people, yes in everyday use. Xerosis cutis is simply the medical name, with xerosis describing severely dry skin. If your skin is only a little tight after a hot shower, you probably have ordinary dry skin. If it cracks, itches constantly or keeps coming back, mention it to a doctor and use the medical term if it helps.
