What Causes Peeling Skin on the Hands in Summer?

Peeling of the hands can stem from numerous causes, with the most common being frequent exposure to chemical substances or environmental factors such as climate changes. So, what causes hand peeling in summer? Below, we address this question.

What Causes Hand Peeling in Summer?

1. Dyshidrotic Eczema

Dyshidrotic eczema is a recurrent, vesicular dermatosis that symmetrically affects the palms and soles. It is commonly associated with excessive sweating of the hands and feet. The exact cause remains unclear, but current evidence suggests it is a type of eczematous hypersensitivity reaction. Contributing factors may include hyperhidrosis, psychological stress, and local irritants. Patients often experience varying degrees of pruritus or a burning sensation. The condition follows a chronic course and tends to recur during spring, summer, and autumn.

2. Keratolysis Exfoliativa

Keratolysis exfoliativa is a superficial, desquamative dermatosis affecting the palms and soles. Its etiology is unknown. Clinically, it begins as tiny, pinhead-sized white spots that gradually expand into thin, parchment-like membranes resembling dried blister fluid. These membranes easily rupture or peel off, leaving behind fine, scale-like, “parchment-like” flakes. Importantly, this condition is asymptomatic—patients report no pruritus, pain, or visible inflammatory signs such as erythema or swelling. It typically occurs symmetrically on the palms; less commonly, it may involve the soles. It can occur year-round but is more frequently observed in spring, summer, autumn, or winter.

3. Nutritional Deficiencies

Certain bodily abnormalities—including hand peeling—are often linked to deficiencies in specific nutrients. For instance, vitamin deficiency is a known contributor to hand desquamation. Vitamin A, a fat-soluble vitamin, plays a vital role in maintaining skin integrity and surface protection. Deficiency may lead to dryness and peeling. Similarly, vitamin B deficiency can manifest as skin peeling, pruritus, and severe dermatitis.

4. Tinea Manuum (Hand Fungus)

A common cause of hand peeling is tinea manuum—a fungal infection of the hands. Typically, peeling begins unilaterally before progressing to both hands. Affected individuals often develop marked pruritus and well-defined, erythematous plaques on the palms. As a contagious condition, prompt antifungal therapy is essential. Patients should seek medical evaluation and treatment at a healthcare facility and use prescribed topical antifungal agents.

The above outlines the primary causes of hand peeling during summer. We hope this information proves helpful.
