Dry Skin: Diagnosis and Treatment
Dry skin, or xerosis cutis, lacks moisture in the outer layer of the skin, leading to itching, flaking, and rough patches.
Diagnosis involves a dermatological examination, while treatment includes moisturisers and lifestyle changes to restore skin health and comfort. The medical term for dry skin is xeroderma.
Understanding the diagnosis and dehydrated skin treatment of this condition is crucial for managing symptoms effectively and maintaining skin health.
What is Dry Skin?
Rough, dry skin or dehydrated skin may have scales or small cracks. Environmental factors like low humidity, frequent hand washing, inadequate hydration, swimming in a chlorinated pool, or difficult hand jobs like mechanics or farming can contribute to the appearance and discomfort associated with xerosis.

Get A Second OpinionCommonly Affected Areas-Dry Skin
- Hands and Fingers: Because of constant washing, exposure to cold, and less oil on the skin, hands become dry. In winter, especially, this is a big problem.
- Elbows and Knees: These areas have fewer oil glands, so they can become rough and dry, making them look cracked and dull.
- Face: The skin on the cheeks, forehead, and around the eyes can become dry, especially if you’re using harsh products or exposed to the sun too much.
- Legs: Legs can get dry and flaky, especially in winter, when the air is so dry.
- Feet: Dry skin on the heels and soles of the feet is very common, particularly in cold weather or after long hours in shoes.
- Scalp: A dry scalp causes dandruff and itchiness, which can be very annoying, especially with the harsh shampoos we use.
- Arms: Arms, especially the outer part, can become dry and patchy, as they have less natural moisture.
Dry skin Types
Contact Dermatitis
- Contact dermatitis is a condition that arises when the skin reacts to a substance it comes into contact with, leading to inflammation in the affected area.
- Irritant contact dermatitis is caused by exposure to chemical irritants like bleach
- while allergic contact dermatitis results from contact with substances to which you have an allergy, such as nickel.
Seborrheic Dermatitis
- Seborrheic dermatitis occurs when the skin produces excessive oil, leading to a red, scaly rash often found on the scalp.
- This condition is typically seen in infants.
Atopic Dermatitis
- Atopic dermatitis, also known as eczema, is a chronic skin condition characterised by dry, scaly patches.
- It is commonly observed in young children.
- Other conditions, such as psoriasis and type 2 diabetes, can also cause the skin to dry out.
Symptoms of Dry Skin
- Itchiness
- Peeling
- Inflammation
- Coarse or flaky areas
- Sensation of tightness or coarseness
- Severe cases may exhibit cracks or splits
- Subtle creases or crevices
- Dull appearance, particularly in darker complexions
- The intensity of these indications may differ based on variables like environmental circumstances, skincare routines, and underlying medical conditions.
Causes of Dry Skin
Dry skin is caused by many factors like cold weather, hot showers, harsh soaps, dehydration, and medical conditions such as eczema or psoriasis.
You can develop dry skin for many reasons, including:
Aging
Older people are more prone to dry skin because of natural changes in the skin. As we age, the sebaceous and sweat glands dry out and the skin loses fat and elasticity, which makes it thinner.
Climate
People who live in dry, desert environments are more prone to dry skin because there is less humidity or humidity in the air.
Genetics
Some people inherit certain skin conditions, such as eczema, which causes dry skin.
Medically referred to as xerosis, dry skin can occur when there is an imbalance in the lipid-protein ratio in the epidermis.
Health Concerns
Certain illnesses, including diabetes and kidney disease, can cause dry, itchy skin.
Occupation
Healthcare professionals, hairdressers, and other professionals are more likely to develop dry, red skin because they wash their hands frequently.
Medication
- Certain medications and skin conditions can also induce dry skin.
- The epidermis is composed of lipids and proteins that help prevent skin dehydration.
- When there are deficiencies in these components, moisture evaporation increases, leading to dry skin.
- Dry skin can heighten sensitivity and make the skin more susceptible to rashes and skin breakdown.
Risk Factors of Dry Skin
- Age: Older adults produce less natural skin oil, increasing dryness.
- Weather: Cold, dry climates and low humidity worsen dry skin.
- Hot Showers: Long, hot baths or showers strip the skin of natural oils.
- Harsh Soaps: Soaps and detergents with strong chemicals can dry out the skin.
- Dehydration: Insufficient water intake can lead to dry, flaky skin.
- Medical Conditions: Conditions like eczema, psoriasis, or diabetes can cause dryness.
- Occupation: Jobs requiring frequent hand washing or exposure to irritants can lead to dry skin.
- Swimming: Prolonged exposure to chlorinated water can dry out the skin.
- Sun Exposure: UV rays damage the skin, reducing its ability to retain moisture.
- Genetics: Family history of dry skin conditions increases risk.
How Dry Skin is Diagnosed?
Diagnosing xerosis involves assessing visible signs and, depending on symptoms, conducting tests to identify underlying causes.
- Doctors identify dryness by observing symptoms like flaking and tightness.
- Allergy tests to identify substances that cause allergic reactions.
- A blood test to look for conditions like diabetes or renal disease.
- Skin biopsy (tissue sample) to test for eczema or other skin problems.
