Introduction

Peeling of the fingertips may result from irritation to the epidermis, leading to desquamation. If no other discomfort is present, this is usually considered normal. Inflammatory lesions in the superficial dermis or epidermis can cause itchy papules, and the local epidermis gradually sheds due to metabolic turnover. Fungal infections may also lead to excessive skin keratinization and subsequent peeling. It is recommended to promptly visit a dermatology department at a hospital for appropriate evaluation and related examinations.

Peeling of the fingertips may be due to physiological factors, or could result from pathological causes such as eczema or hand fungus. The specific analysis is as follows:

I. Physiological Phenomenon

If the fingers are exposed to chemicals for prolonged periods or if skin moisturization is neglected, the epidermis may become irritated and lead to peeling. If no other discomfort is present, this is usually considered normal. It is recommended to maintain proper hand hydration and protection in daily life, including regular application of hand cream.

II. Pathological Causes

1. Eczema

When the fingertips are exposed to external irritants, inflammatory changes may occur in the superficial dermis or epidermis, leading to itchy papules and localized peeling of the skin over time due to cellular turnover. Medications such as halometasone cream, methylprednisolone tablets, or tacrolimus ointment may be used under medical guidance to relieve symptoms.

2. Hand Fungus (Tinea Manuum)

Prolonged exposure of the fingers to water increases susceptibility to fungal infection, which can cause excessive keratinization and subsequent skin peeling. In such cases, antifungal medications like terbinafine cream or bifonazole cream may be used as directed by a physician.

Aside from the above common causes, conditions such as palmoplantar pustulosis may also be responsible. It is advisable to promptly visit the dermatology department of a hospital for appropriate evaluation and diagnostic testing.
