Understanding Dry Skin: Causes, Concerns, and Treatments

By Dr. Ashley Cauthen

Dry skin, also known as xerosis, is a common skin condition that affects people of all ages and skin types. It occurs when the skin loses moisture and becomes dehydrated, leaving it feeling tight, rough, and sometimes even flaky or cracked. Although dry skin is often a temporary issue caused by environmental factors, it can sometimes indicate a more serious underlying condition. Understanding the causes, concerns, potential illnesses associated with dry skin, and available treatments can help you manage the condition effectively.

Causes of Dry Skin
Dry skin can be triggered by various factors. Some of the most common causes include:

1. Environmental Factors
• Cold Weather: During the colder months, lower humidity levels can strip the skin of its natural moisture. This is especially common in areas with harsh winters or air-conditioned spaces.
• Hot Showers or Baths: While hot water feels soothing, it can actually remove essential oils from the skin. Prolonged exposure to hot water can lead to dryness.
• Sun Exposure: Excessive sun exposure can damage the skin and cause it to lose moisture. Sunburn can also exacerbate dry skin, especially in people with sensitive skin.

2. Skin Care Products
• Harsh Soaps: Some soaps and cleansers contain ingredients that can strip the skin of its natural oils, contributing to dryness.
• Fragrances and Dyes: Products with artificial fragrances or dyes can irritate the skin and contribute to dryness, especially for people with sensitive skin.

3. Medical Conditions
Certain medical conditions can also contribute to dry skin:
• Eczema (Atopic Dermatitis): This chronic condition causes the skin to become inflamed, itchy, and dry. People with eczema often have a weakened skin barrier, making it more prone to dryness.
• Psoriasis: Psoriasis is an autoimmune condition that leads to the rapid buildup of skin cells, causing scales and patches of dry, thick skin.
• Hypothyroidism: An underactive thyroid can lead to a reduction in the skin’s ability to produce oils, resulting in dry skin.
• Diabetes: High blood sugar can lead to dehydration, which in turn causes the skin to become dry.
• Dehydration: Insufficient water intake can lead to dehydration, which affects the skin’s hydration levels, leaving it dry and flaky.

4. Age
As we age, the skin’s natural ability to retain moisture decreases. The production of natural oils slows down, and the skin becomes thinner and less able to retain water. This makes older adults more prone to dry skin.

5. Medications
Some medications, such as those used to treat acne, high blood pressure, and cholesterol, can have side effects that cause dryness. Diuretics, for example, promote fluid loss, which can lead to dehydration and dry skin.

Concerns and Illnesses Associated with Dry Skin
While dry skin is often a mild, temporary issue, it can sometimes lead to more serious health concerns. If left untreated or poorly managed, dry skin can lead to the following conditions:

1. Infections
Dry, cracked skin is more susceptible to infections. Small tears or cracks in the skin provide an entry point for bacteria, fungi, or viruses, which can lead to infections like cellulitis, athlete’s foot, or fungal rashes.

2. Eczema Flare-Ups
For individuals with eczema, dry skin can trigger flare-ups of the condition, leading to red, itchy, and inflamed patches. Without proper care, these flare-ups can become more severe and difficult to manage.

3. Psoriasis Aggravation
In individuals with psoriasis, dry skin can cause the skin to crack and peel, making the condition worse. Dryness can increase the discomfort caused by psoriasis and hinder the effectiveness of treatments.

4. Skin Sensitivity
Dry skin is more sensitive to environmental factors like heat, cold, and sun exposure. This heightened sensitivity can lead to further irritation and discomfort.

Home Remedies for Dry Skin
Treating dry skin at home often involves using simple, affordable methods to restore moisture and protect the skin. Here are some helpful tips:

1. Moisturize Regularly
Using a good-quality moisturizer is one of the most effective ways to treat dry skin. Look for creams or ointments with ingredients like hyaluronic acid, glycerin, ceramides, and petrolatum, which help lock in moisture. Apply moisturizer immediately after bathing to trap water in the skin.

2. Use Gentle Skin Care Products
Switch to mild, fragrance-free cleansers and avoid harsh soaps. Look for products labeled as “moisturizing” or “hydrating” to help replenish the skin’s moisture.

3. Limit Hot Showers and Baths
Avoid prolonged exposure to hot water, as it can strip the skin of its natural oils. Opt for lukewarm water instead and try to keep your showers short.

4. Stay Hydrated
Drinking plenty of water throughout the day helps to maintain the skin’s hydration levels from the inside. Aim for at least 8 glasses of water per day.

5. Humidify Your Home
Using a humidifier in your home can help prevent moisture loss from the skin, particularly in winter when indoor air tends to be dry.

In-Office Treatments for Dry Skin
For more persistent cases of dry skin or conditions that don’t improve with home remedies, a visit to our dermatology office may be necessary. Here are some treatments we may recommend:

1. Prescription Topicals
For conditions like eczema or psoriasis, we may prescribe topical corticosteroids or other prescription-strength creams to reduce inflammation and hydrate the skin. These treatments can help control flare-ups and keep the skin’s moisture levels balanced.

2. Hydration Therapy
For extremely dry skin, especially in cases of eczema or psoriasis, we may recommend treatments that hydrate the skin deeply. This may include the use of professional-grade moisturizers or topical treatments that are more effective than over-the-counter options.

3. Light Therapy
Light therapy (phototherapy) may be used for patients with psoriasis or other chronic skin conditions. This treatment uses ultraviolet light to help improve the skin’s condition and reduce symptoms of dryness, redness, and irritation.
