Skin Peeling: 9 Common Causes & What to Do

September 2022

Skin peeling occurs when the most outer layers of the skin are shed. This can occur with mild situations, like skin dryness.

However, if it is accompanied by other symptoms (like redness, pain, itching or swelling) it may a sign of another health condition, like dermatitis, a fungal infection or even lupus.

In most cases, skin peeling can be prevented through measures like moisturizing the skin or using the right hygienic products for your skin type. Nonetheless, if symptoms persist for over a week, or if the peeling is very uncomfortable, you should see a dermatologist for further assessment and possible treatment. 

The most common causes of skin peeling include: 

1. Dry skin

Dry skin, medically known as xerodermia, occurs when the sebaceous glads and sweat glands produce less sweat and oil then usual. This leads to dry skin that ends up peeling.

Generally, a sun burn is more common in areas that are more prone to be exposed ot the sun, like the face, arms or back. 

What to do: You should bathe in cold water and apply after-sun creams to help relieve any discomfort and promote skin healing. 

3. Contact dermatitis

These symptoms can emerge immediately or up to 12 hours after initial contact, depending on the substance.

What to do: You are advised to avoid contact with the triggering substance, and to was the skin with cold water and pH neutral soap. You can also take an anti-histamine as directed by your doctor to soothe irritation and prevent worsening.

5. Atopic dermatitis

Atopic dermatitis is an inflammatory disease that causes dry skin. It occurs due to the skin’s inability to retain water and also due to insufficient production of fat by the sebaceous glands, which can increase the skin’s risk for peeling. Atopic dermatitis is associated with intense itching and most commonly affects the elbows, knees, wrists, back of the hands, feet and genital area.

This illness can appear in childhood and tends to improve up until adolescence, although many people experience further episodes in adulthood.

When the scalp is affected, seborrheic dermatitis is also referred to as "dandruff", however it can also occur in other areas with hair (like the beard or eyebrows) or areas of the body that bend (like the armpit, groin or ears). 

Skin peeling caused by seborrheic dermatitis is normally oily in nature and tends to worsen during periods of stress or with climate changes. It is often accompanied by symptoms like redness and itching.

What to do: Treatment usually includes the use of topical antifungals that are prescribed by a doctor. To prevent worsening, you should also reduce body moisture when possible by drying the body off following a shower, for example, any by using light clothing.
