A Guide To Dry Skin Disorders In The Lower Extremity

A Guide To Dry Skin Disorders.

At this wintry time of year, more patients may be presenting with cracked heels and itchy feet due to dry skin. Accordingly, this author discusses the diagnosis and treatment of different forms of dry skin, including dry skin concomitant with common diseases. 

How many times a day do you see any of these conditions: stasis eczema, eczema, atopic dermatitis, contact dermatitis, xerosis, psoriasis or stucco keratosis? The skin might seem like a structure you have to get past to get to the muscles, bones, and other organs. However, the skin problems are what bring patients into a podiatrist’s office with symptoms like tightness, tingling, itchiness, burning, scaling, flaking, and lichenification. When you cannot concentrate on your work because you are scratching.  When your sleep is interrupted because of burning sensations or when you have noticeable dry skin patches on your legs, then dry skin is in the fast lane.

The skin can be a “mirror” of what is going on in the body and therefore needs to be taken into concern and consideration. The lower legs and heel are notoriously problematic with dry skin symptoms. However, when visiting your podiatrist for these problems, the hands and forearms will also be examined. This will help in evaluating the problem to get a big picture of what is going on. The feet do not exist in a vacuum.    The skin acts as a barrier and protects underlying tissues from infection, desiccation, chemicals, and mechanical stress. Disruption of these functions results in increased transepidermal water loss and decreases in the stratum corneum’s water content and is associated with conditions like atopic dermatitis, eczema, xerosis, contact dermatitis, and other chronic skin diseases.

Moisturizers can improve these conditions through restoration of the integrity of the stratum corneum, acting as a barrier to water loss and replacement of skin lipids and other compounds.1 Despite the knowledge of well-recognized aggravating factors, the etiology of dry skin conditions is an enigma and the management of the condition is often suboptimal.2    In the foot and ankle region, we have three types of skin: plantar skin, which has no oil glands and the largest number of sweat glands anywhere; dorsal skin, which is normal skin; and the skin overlying the shin, which is the thinnest and more prone to injury.    Dry skin occurs when the stratum corneum is depleted of water. The skin’s outer layer consists of dead, flattened cells that gradually move toward the skin’s surface and slough off. The cells of the stratum corneum have lost their nucleus, are rich in keratin, and are known as “corneocytes.”3 Intercellular lipids bind the corneocytes together. When this layer is well moistened, it minimizes water loss through the skin and helps keep out irritants, allergens, and germs.

However, when the stratum corneum dries out, it loses its protective function. This allows greater water loss, leaving your skin vulnerable to environmental factors.    Under normal conditions, skin requires a water content of 10 to 15 percent to remain supple and intact.4 This water gives the skin its soft, smooth, and flexible texture. The water comes from the atmosphere, the underlying layers of skin and sweat. Oil produced by skin glands and fatty substances produced by skin cells acts as natural moisturizers, allowing the stratum corneum to seal in water.

The skin contains natural moisturizers: ceramides, glycerol, urea, and lactic acid. This helps rehydrate the skin to prevent water loss, which is the reason that many of the products out on the market contain urea, lactic acid, salicylic acid, and glycol. They are trying to “mirror” the skin. The essential ingredient of an emollient is lipid (fats, waxes, and oils).5    Ceramides are the natural moisturizing factors and are the major lipid constituents of the intercellular spaces of the stratum corneum. These lipids theoretically provide the barrier property of the epidermis.2 The link between skin disorders and changes in barrier lipid composition, especially in ceramides, is difficult to prove because of the many variables involved. However, most skin disorders that have a diminished barrier function present a decrease in total ceramide content with some differences in the ceramide pattern.

Patients with skin diseases such as atopic dermatitis, psoriasis, contact dermatitis, and some genetic disorders have diminished skin barrier function.6    We continuously lose water from the skin’s surface by evaporation. Under normal conditions, the rate of loss is slow and the water is adequately replaced. Characteristic signs and symptoms of dry skin occur when the water loss exceeds the water replacement, and the stratum corneum’s water content falls below 10 percent.7    Any factor that damages the stratum corneum can interfere with its barrier function and lead to dry skin. By and large, the feet are not subject to the typical factors that affect skin elsewhere including long, hot showers and cold, dry air, detergents, and solvents. The feet are more subject to chafing and rubbing due to walking as well as the interplay between socks and shoes.


What You Should Know About Skin Structure And Ethnicity

A recent study has demonstrated that skin properties at the level of the stratum corneum vary considerably among ethnic groups.8 East Asian and Caucasian skins are characterized by low maturation and a relatively weak skin barrier. African-American skin is characterized by low ceramide levels and high protein cohesion in the uppermost layers of the stratum corneum.    There is more transepidermal water loss in African-American skin than in Caucasian skin, predisposing patients to more xerosis. Ceramides are the major lipid constituent of lamellar sheets present in the intercellular spaces of the stratum corneum. These lamellar sheets provide the barrier property of the epidermis.2    Ceramide levels in African-American skin are the lowest while Caucasians, Hispanics, and Asians have the highest levels.9 So one can infer that black skin is more prone to xerosis and the pathology can be due to xerosis.


African-American communities use the term “ashy” to describe dry skin. The skin is dry, cracked, and powdery, and one can see the skin flakes more easily on dark skin. In our society, the ashy color is considered unacceptable and many African Americans use oils or petrolatum to address this.10    We generally regard moisturized skin as healthy and healthy-looking. There may be corresponding changes in the optical properties when the skin is moisturized.11 In healthy skin, there is less light scattering at the skin surface and more light penetration into the deeper skin layers when the skin is moisturized. As a result, the skin appears darker, more pinkish, and more translucent.    One popular moisturizer is shea butter. Shea butter is a yellow “fat” or “oil” extracted from the nut of the African shea tree. Complications of the use of occlusive emollients such as Vaseline and shea butter used on the dorsal foot and lower leg can result in “oil folliculitis” if the leg is hairy.

Pertinent Insights On The Relationship Between Footwear And Dry Skin

Unlike any other anatomical area, the feet are subject to much chafing, rubbing, and sweating, which can affect the skin surface. Wearing shoes without socks can dry out the feet depending on the material the shoes are made from. Due to body heat and moisture, there is almost always higher heat and humidity inside your shoes. If the shoe material is breathable as in leather, the heat and humidity being pushed out can escape from the shoes and such ventilation keeps your foot dry and comfortable. Non-breathable material such as vinyl blocks the heat and humidity inside. Some people have sweatier feet than others and this will interact with the shoe as well. Sweaty feet dry out the skin quicker. Shoes that do not fit as well (flip flops, open-backed sandals) produce more friction to dry out the skin.    However, when dry skin occurs on the feet, the symptoms of discomfort are magnified due to shoe wear, the stretching of the skin on the feet each time we step down, and certain synthetic materials in the socks and shoes that dry the skin out even more. Due to the confining nature of the shoes we wear and the lack of fresh air that hits the skin of the feet due to our socks and shoes, dry feet need specialized care in order to prevent pain. In many cases, the shoes we wear can also protect our feet from dry skin and fissures if they fit properly and are made of breathable material.


Abnormal foot mechanics and deformities cause abnormalities in the way we walk. This subsequently causes certain areas of the feet to bear abnormal amounts of weight, which may result in dry patches, calluses, corns, and fissures. Orthotics and wearing the correct shoes help to spread out the abnormal weight and reduce friction. One must remember that the skin of the feet has no oil glands and must rely on the sweat glands to moisturize the skin. Sweat glands operate by secreting a substance comprised mostly of water, sodium chloride, and electrolytes. Accordingly, sweat is more “drying” than moisturizing. Each of our feet is densely covered with approximately 250,000 eccrine sweat glands, making feet one of the sweatiest places on the body.


The lack of oil glands makes preventing dry skin difficult but if we had oil glands on our feet, we would slip and slide with each step we took. Socks absorb sweat and are supposed to prevent blisters. It is known that certain synthetic socks can decrease the temperature of the foot as much as 3º and that is enough to prevent blister formation by limiting sweating. Dry feet are not the same as dry skin of the feet.  One study looked at fabric softeners and surmised that fabric softeners provide benefits to individuals with dry skin because of the decreased friction of the garments against the skin.12 Since friction results in heat, the heat will dry your feet out faster. It is known that nylon and rayon socks cause dryness to the skin.    In one study, the prevalence of Type IV hypersensitivity to rubber allergens was evident in patients with stasis eczema and/or venous leg ulcers over an 18-month period.13 Accordingly, vascular hose in some patients may result in a dry, itchy skin response and when not wearing the hose at night, patients must moisturize.

Treatment Tips For Specific Skin Conditions

Stucco keratosis. This is a keratotic papule that is usually present on the distal lower acral extremities of males. Stucco keratosis seems to appear with a higher frequency in males but it is not genetic. The lesion is asymptomatic and patients usually do not complain of having the lesions. The name stucco keratosis derives from the “stuck on” appearance of the lesions. The lesions are usually found in elderly patients. The differential diagnoses are seborrheic keratosis and melanoma.

Xerosis. Xerosis results in generalized or localized pruritus and dry, itchy skin. Rubbing and scratching causes increased irritation, leading to more pruritus and inflammation.14

Lichen simplex chronicus (neurodermatitis). Prolonged itching and scratching can lead to skin that is thick, scaly, and leathery. The patches can be raw, red, or darker than the rest of your skin.

Stasis dermatitis (venous eczema, varicose eczema). Stasis dermatitis is not “true” dermatitis but instead is due to venous hypertension in the lower leg. This is caused by insufficiency of the superficial veins as well as the long saphenous vein. One study found that when patients received classical flush ligation and a saphenectomy, lower leg dermatitis healed in all 10 patients within eight to 12 weeks, and there was no recurrence.15

Eczema craquelé (winter itch, asteatotic eczema, xerotic eczema, desiccation dermatitis). Eczema craquelé occurs mostly in elderly individuals with tight, red, dry skin that progresses to superficially fissured dermatitis. The irregular network of fissures resembles a dry riverbed and is visible on the shins of the legs. This is essentially “advanced” xerosis.9

Atopic dermatitis. In this form of eczema, one has more sensitive and drier skin due to an autoimmune condition.

Psoriasis. Psoriasis involves the rapid buildup of rough, dry, dead skin cells that form thick scales. These scales bleed when patients pick them off. It occurs mostly on the plantar skin of the foot.

Which Came First, Dry Skin Or The Itch?

Dry, “flaky” skin is an irritant and causes cutaneous inflammation, which in turn results in pruritus. Once the itch-scratch-itch cycle starts, the skin gets worse. The inflammation irritates the nerve endings.16 Treatment of dry skin is one of the most important measures against pruritus.17 Prevention is very important.

Researchers have rarely found correlations between itch and objective measures of barrier function and skin dryness such as skin hydration and transepidermal water loss. Recent experimental evidence indicates that damage to the stratum corneum with acetone/ether and water elicits a scratching response in mice and rats.18

Skin diseases associated with itch include eczema, atopic dermatitis, dry skin, contact dermatitis, psoriasis, lichen planus and bacterial infection.

Keys To Diagnosing Dry Skin

For the most part, dry skin is a purely clinical diagnosis. A thorough history, review of systems, and physical examination are critical to determining its cause. Examination of the skin may be misleading. There are frequently only secondary lesions, eczematous changes, lichenification, and excoriation, and the inciting cause may not be present. If primary lesions are present, a skin biopsy can lead to a diagnosis. One must consider systemic causes of dry skin/itch, such as cholestasis, uremia, hyperthyroidism, medications, or lymphoma.

However, if the normal topical treatments are not resolving the condition, have the lab test for thyroid function, renal function, liver function, HIV, zinc level, cancer, or Sjögren’s syndrome.

Treating Dry Skin

The first step to treat dry skin is to add water to the skin and apply a hydrophobic substance to keep it there. The substances include water-in-oil creams and lotions or 100% oil ointments to lock in the water. No matter what the cause of dry skin is, occlusive moisturizers, humectant emollients, and keratolytics are three commonly used topical treatments. For the most part, emollients work by retaining water in the skin where it is needed and enabling the repair of damaged cells on the skin’s surface. Emollients also act as a barrier to the environment, preventing irritants from penetrating the outer layer of the skin (epidermis) by creating a protective lipid film.3 

Occlusive emollients such as petrolatum prevent water loss only by acting as a layer of oil on the surface of the skin to trap water and prevent evaporation. Humectant emollients such as Eucerin (Beiersdorf) penetrate the stratum corneum and draw water from the dermis to retain it in the epidermis.

Keratolytics such as lactic acid, salicylic acid, and glycolic acid help remove scales. Many times all three are together in one product.    


While topical steroids do not treat dry skin, they do decrease the inflammation of the skin and the “itch” factor. Maximum hydration can occur with 60% propylene glycol in water applied under occlusion.19 When using topical steroids, choose a mid-potency steroid for dorsal skin and a high-potency to super-high-potency steroid on plantar skin. All topical steroids have increased absorption through the incomplete skin barrier.    

When discussing the choice of emollients, a continuum exists between oily ointments and water-based creams and lotions. Ointments are best for the driest of skin conditions and are used at home when patients are not wearing tight clothes or working with others. The application of ointments can cause folliculitis in hairy areas, an unusual issue in the foot and ankle. The frequent use of emollients reduces the need for steroids.20

To avoid or treat xerosis, patients should moisturize their feet right after a bath or shower. They should avoid soaking their feet in hot water for long periods, using drying soaps on the feet, or scrubbing their feet dry.    Anecdotal and limited data suggest that gabapentin, cutaneous field stimulation, serotonin antagonists, and ultraviolet B phototherapy may reduce itch in some of these patients.

Combating The Effects Of The Sun

The sun adds to the drying out of the skin just like the cool air of winter and the dry air of a desert. If the skin barrier is compromised, patients can have increased dryness. Snow, sand, and water increase the need for sunscreens because they reflect the sun’s rays. A sunscreen product acts like a very thin bulletproof vest, stopping the ultraviolet photons before they can reach the skin and inflict damage. It contains organic sunscreen molecules that absorb UV and inorganic pigments that absorb, scatter, and reflect UV. There are sunscreens now that help prevent dry skin by moisturizing as well.21   

The sun’s heat dries out areas of unprotected skin and depletes the skin’s supply of natural lubricating oils. In addition, the sun’s UV radiation can cause burning and long-term changes in the skin’s structure. The sun causes dry skin, sunburn, and actinic keratosis. Skin appears dry, flaky, and wrinkled.

Other Considerations With Dry Skin Conditions

Cracked heels. Podiatrists frequently see cracked heels due to poor foot mechanics, prolonged standing, being overweight, poor shoe gear, open-backed shoes, and the usual cause, flip flops. It is the perfect storm of friction, lack of oil-producing glands and inadequate shoegear. In these conditions, the fat pad under the heel expands sideways and increases the pressure on the side. If there is any lack of moisture in the heel, it will crack.    Accordingly, if you have an overweight patient with diabetes who wears house slippers much of the day, expect her to have cracks in the heels. Cracked heels are more common during the winter months although if you spend extended amounts of time in the sun, it can also dry out your skin to cause cracked heels. Medical conditions including diabetes, obesity, thyroid disease, and psoriasis may also cause dry, cracked heels.    

Aged/elderly skin. In elderly skin, the epidermis thins, and the corneocytes do not adhere to each other as well and the skin loses its water-binding capacity. Dry skin is itchy skin and itchy skin is dry skin. It is difficult to split them up. Itching in the elderly presents a diagnostic and therapeutic challenge. A thorough history, review of systems, and physical examination are critical to determining the cause of itching.    Examination of the skin may be misleading.

There are frequently only secondary lesions, eczematous changes, lichenification, and excoriation, which we may misdiagnose as primary dermatitis. Xerosis may be the cause but it is sometimes merely coincidental. If primary lesions are present, a skin biopsy can aid in diagnosis. Consider systemic causes of itching such as cholestasis, uremia, hyperthyroidism, medications, or lymphoma. 

If the cause remains elusive, consider idiopathic itching of the elderly or so-called “senile pruritus.” The pathophysiology of this form of pruritus is poorly understood but, likely, age-related changes of the skin, cutaneous nerves, and other parts of the nervous system play a role.22

Treating Dry Skin That Is Concomitant With Common Diseases

Certain disease states can cause xerosis so in the workup, one should make note of congenital and acquired ichthyoses, atopic dermatitis, hypothyroidism, Down syndrome, renal failure, malnutrition, malabsorption, HIV, lymphoma, liver disease, Sjögren’s syndrome and certain drugs.

End-stage renal disease (ESRD). This is a progressive and irreversible kidney dysfunction lasting three months or more. Nearly all patients with ESRD have at least one dermatological disorder, and these skin and nail changes can occur before or even after initiation of dialysis or transplantation.23 Some authors have suggested that ESRD–associated xerosis may be a result of decreased water content in the epidermis. Clinical and histologic evaluations have shown an overall decrease in sweat volume in patients with uremia as well as the atrophy of sebaceous glands.24

Xerosis occurs in 50 to 75 percent of dialysis patients.24 It manifests as poor skin turgor with scaling, dryness and fissuring of the skin, particularly affecting extensor surfaces of extremities.    

Of those with chronic renal failure, 15 to 49 percent experience pruritus. Of those patients undergoing dialysis, the prevalence is up to 50 to 90 percent but as dialysis has improved, it has become less common.24 In acute renal failure, pruritus is very uncommon. The pruritus of ESRD is most often generalized and light but can be severe and unremitting.23

Hypothyroidism. Hypothyroidism is more common in women and people over the age of 50. The thyroid produces too few thyroid hormones and this reduces the activity of the sweat and oil glands, leading to rough, dry skin. Symptoms with a high specificity for hypothyroidism include constipation, cold intolerance, proximal muscle weakness, hair thinning, and dry skin. Dry skin can be a symptom of hypothyroidism in infants and children as well. A blood test can determine the level of thyroid stimulating hormone as well as thyroid hormones T3 and T4.


Diabetes. People with diabetes have a high incidence of xerosis of the feet, especially on the heels. While assessing for predictors of foot lesions in patients with diabetes, one study found that 82.1 percent of their patients had skin with dryness, cracks, or fissures.25 An unpublished survey of 105 consecutive patients with diabetes conducted by one of the authors revealed that 75 percent had clinical manifestations of dry skin. Dry skin often leads to cracks and fissures, which can serve as a portal of entry for bacteria.    

Despite possible “dry skin” definition discrepancies across the studies, it is clear that skin dryness is one of the earliest and most common manifestations of type 1 diabetes. The clinical observations are supported by objective findings of a reduced hydration state of the stratum corneum and decreased sebaceous gland activity in patients with diabetes without any impairment of the stratum corneum barrier function.26

Liver disease. The liver neutralizes toxins and filters bile salts. If the liver’s function is impaired, these materials can accumulate in the body, and deposition in the skin causes irritation and itching. In cholestatic liver disorders such as primary sclerosing cholangitis and obstructive gallstone disease, pruritus tends to be generalized but is worse on the feet and hands.27

In Conclusion

Dry skin can be persistent and recurring due to the long list of possible causes. Clinicians often treat dry skin with hydrophilic and/or lipophilic moisturizers.

Hydrophilic moisturizers must penetrate the stratum corneum deeply to function properly whereas lipophilic moisturizers should remain in the upper stratum corneum layers.28

Traditionally, clinicians used humectant and occlusive technologies to treat dry skin. Originally, non-lamellar forming ingredients such as petrolatum were in use but recent research has shown an advantage of using lamellar-forming factors such as ceramides, pseudoceramides, and phospholipids.29

As with all topical treatments, adherence is the great challenge one faces in the management of skin diseases. Strong odor from ingredients and greasy compositions may be disagreeable to the patients. Furthermore, low pH and sensory reactions, from lactic acid and urea, for example, may reduce patient acceptance.30

The number of studies on skin barrier function and hydration is endless. There is a long list of products available and some may work better depending on certain skin characteristics of the person. Many podiatry-friendly companies have products that include CeraVe (Valeant), Eucerin, AmLactin (Upsher Smith), Cetaphil (Galderma), Borage Therapy (ShiKai), Uramaxin (Medimetriks), Carmol 40, Lubriderm (Johnson and Johnson), and Aveeno (Johnson and Johnson).
