Let’s head onto the next section to explore the causes behind scaly skin patches
What Causes Scaly Skin?
White scaly patches on your skin can be due to multiple factors. Dry and cold weather is one of the most common causes of scaly skin. Low humidity in the air reduces the function of the skin barrier and increases susceptibility to injuries. This may lead to your skin drying out (1). Exposure to common allergens and using products high in chemicals may result in an allergic reaction. Scaly skin may also be a symptom of the following medical conditions.
1. Psoriasis
Psoriasis is a dermatological condition characterized by itchy, scaly patches on your knees, elbows, and scalp. Diagnosed equally in men and women, a genetic history, stress, and infections have been attributed to the development of psoriasis (2). A 2021 study published in the Frontiers in Medicine journal analyzed data from the Global Burden of Disease (GBD) 2019 study. It estimated that there were 4,622,594 incident cases of psoriasis globally in 2019, with an age-standardized incidence rate of 57.8 per 100,000 people, which marked a decrease of 20% from 1990. Below are the symptoms associated with psoriasis (3).

2. Eczema
Also known as atopic dermatitis, eczema is a chronic skin disease commonly seen in children. Dry skin is a symptom commonly seen in eczema. This is due to the dysfunction of the skin barrier which is responsible for retaining moisture. Although the definitive cause of eczema is currently unknown, researchers suggest that it is a combination of genetics and environmental triggers (4). The symptoms associated with eczema are (5):
itchy and dry skin scaly patches on face, knees, and elbows erythema – skin rashes thickening of skin pityriasis alba – dry, pale patches on the face
3. Actinic keratosis
Actinic keratosis is a skin disease that has characteristic symptoms such as rough, scaly lesions all over the neck, face, hands, and legs. Caused due to prolonged exposure to ultraviolet rays, actinic keratosis may be the precursor to skin cancer (6). Symptoms associated with actinic keratosis are (7), (8):
Rough, scaly patches Ulcers Burning sensation Bleeding Itchy papules or nodules
4. Athlete’s Foot
As the name suggests, athlete’s foot is a disease commonly found in people from athletic or military backgrounds. Also known as tinea pedis, this condition is caused due to fungal infections. The symptoms include (9), (10):
White, scaly skinbetween the toes Red blisters on the foot Itching and burning sensation Soggy skin Pain Difficulty walking
5. Contact Dermatitis
Have you ever used a detergent or skincare product, only to see your skin filled with angry rashes? If so, it may be a case of contact dermatitis. The chemicals present in the products modify the protein structure which leads to the inflammation of the skin. This condition may also cause dry itchy skin, making the affected areas feel uncomfortable and irritated. The clinical manifestations of this condition are (12):
Tenderness Dry scales Pus-filled blisters Hyperpigmentation Flaky crusts over your skin
6. Seborrheic Dermatitis
Seborrheic dermatitis is a chronic skin condition commonly diagnosed in infants and adults aged between 30 to 40 years. While researchers aren’t completely sure of the exact cause, few factors may play a role in its development. Individuals with HIV, exposure to Malassezia fungus, and Parkinson’s disease have been linked with the risk of developing this condition. Some of the symptoms include (13):
Yellow scales on the face, forehead, back, and upper chest White flaky scales on the scalp Itchy skin Dandruff
7. Thyroid Problems
Thyroid problems may contribute to dry and scaly skin (15). Hypothyroidism or an underactive thyroid may lead to reduced oil production. This may cause dry and scaly skin. On the other hand, hyperthyroidism or an overactive thyroid may accelerate skin cell turnover, resulting in flakiness, skin peeling, and itching (16). Additionally, thyroid imbalances can impact sweat gland function, affecting skin hydration. Some of the symptoms associated with thyroid problems are (16):
Dry, flaky skin Itching or irritation Redness or inflammation Patches of rough, scaly texture Peeling or cracking
These skin changes are often associated with other symptoms like fatigue, weight fluctuations, and hair loss, highlighting the interconnected nature of thyroid health and the skin. While having dry scaly skin is quite common, leaving it untreated may lead to possible health complications.
What Are The Potential Complications Of Scaly Skin?
Scales on your skin make your skin vulnerable and increase the risk of developing an infection. This may lead to the development of serious health complications. Research suggests that actinic keratosis may be a precursor to squamous cell carcinoma (7). Prolonged exposure to ultraviolet radiation leads to a change in the molecular structure, thus increasing the chance of developing skin cancer. Studies have also shown that 20%-30% of psoriasis patients develop joint inflammation called psoriatic arthritis (2). Recognizing other symptoms along with scaly skin is necessary for timely medical intervention.
When Should You Visit a Doctor?
