Introduction
The term "finger belly" usually refers to the fingertip pad. Under normal circumstances, possible causes of cracks on the fingertip pads may include dry skin, chemical irritation, tinea manuum (hand fungus), eczema, psoriasis, and other conditions. It is recommended to seek timely medical examination to identify the underlying cause and receive standardized treatment under the guidance of a qualified physician. In daily life, try to minimize contact with chemical substances such as detergents and cleaning agents, and wear rubber gloves for protection when necessary.
The fingertip usually refers to the finger pulp. Under normal circumstances, possible causes of cracks on the finger pulp may include dry skin, chemical irritation, tinea manuum, eczema, psoriasis, etc. It is recommended to seek timely medical examination, identify the underlying cause, and undergo standardized treatment under the guidance of a qualified physician. Detailed information is as follows:
1. Dry skin: When the skin lacks sufficient moisture, its stratum corneum becomes fragile and tends to peel off easily. In the finger pulp area, this dryness may lead to skin cracking and formation of fissures. Drinking adequate water and using suitable cosmetic products to replenish moisture may help alleviate the condition.
2. Chemical irritation: Prolonged contact of hands with chemical substances such as detergents, cleaners, and disinfectants may damage the skin's natural protective barrier, potentially leading to dryness and cracking. Avoid further contact with irritant chemicals and use moisturizers or other skincare products to restore the skin barrier function.
3. Tinea manuum: Tinea manuum is a fungal infection that affects the skin of the hands, presenting symptoms such as blisters, papules, dryness, and skin cracking. It may be accompanied by itching and flaking, and severe cases may involve pain. Follow medical advice to use antifungal medications like amorolfine hydrochloride cream, luliconazole cream, or itraconazole capsules to relieve symptoms.
4. Eczema: This condition may be associated with factors such as contact allergens or endocrine disorders. Eczema can impair the skin barrier function, causing the skin to become dry, rough, and prone to cracking. Symptoms may include itching, pain, and flaking. Under a doctor's guidance, topical medications such as clobetasol propionate cream, zinc oxide ointment, or calamine lotion may be used for treatment.
5. Ichthyosis: Ichthyosis refers to a group of inherited keratinization disorders. Due to gene mutations, the normal metabolism of skin cells is disrupted, and the abnormally thickened stratum corneum is more susceptible to cracking from external forces. Symptoms may include itching and pain. Follow medical advice to use medications such as salicylic acid ointment, tretinoin cream, or tacrolimus ointment for treatment.
In daily life, try to minimize contact with chemical substances such as detergents and cleaning agents, and wear rubber gloves for protection when necessary. At the same time, maintain hand hygiene to prevent fungal infections.
