The causes of eczema in men are varied and usually involve a combination of internal and external factors. It is recommended to start by examining lifestyle details to identify potential triggers and consult a doctor promptly.

Specifically, this may include the following aspects:

1. Weak skin barrier function
Some men are born with more sensitive skin, or live in dry environments for a long time, which reduces the skin's self-protection ability, making it more susceptible to redness, swelling, itching, and other reactions from external irritants.
2. Exposure to irritating substances
Everyday contact with detergents, chemicals, and metal jewelry can irritate the skin. In men who sweat excessively, if they don't clean themselves promptly, the retained sweat can trigger localized eczema.
3. Influence of lifestyle habits
Habits such as frequently bathing in excessively hot water, over-cleaning the skin, and wearing non-breathable synthetic fiber clothing may damage the protective layer on the skin's surface and increase the likelihood of developing eczema.
4. Stress and lifestyle factors
Prolonged mental stress, staying up late, or fatigue may affect the body's regulatory ability, indirectly leading to recurring or worsening skin problems.
If eczema symptoms appear, first record recent contact with items and changes in lifestyle habits to avoid scratching the affected area. It is recommended to choose loose-fitting cotton clothing, use mild bath products, and keep the skin moderately moisturized. If symptoms persist or worsen, consult a dermatologist promptly for a professional examination to determine the specific cause and receive proper treatment.
