Antonio Clemente, dermatologist: "I tell my patients that dermatitis isn't cured with moisturizers, but with dermatological treatment."

Sweating is a natural mechanism that helps regulate body temperature, although it can also cause dermatological problems . Dermatologist Antonio Clemente , a member of the Association of Dermatology and Venereology, warns that many types of dermatitis and eczema worsen with sweat. These conditions frequently occur in areas subject to friction and moisture, such as the groin, armpits, or thighs. In these cases, he points out, it's best to act quickly and under medical supervision.

As Antonio Clemente reports in an article for the EFE news agency , sweat can cause irritant dermatitis, a reaction that causes itching , redness, and scaling. The specialist warns that it shouldn't be treated solely with moisturizing products. "I tell my patients that dermatitis isn't cured with moisturizing creams, but rather with dermatological treatment," he says. Also common is prickly heat and, in less common cases, cholinergic urticaria, aggravated by heat.

Retained moisture in the skin promotes infections such as folliculitis or intertriginous dermatitis , especially in skin folds. These lesions, if left untreated, can become complicated by bacteria or fungi. Clemente advises against the use of topical antihistamines due to the risk of photosensitivity in summer . Instead, he recommends corticosteroids to reduce inflammation and antibiotic or antifungal creams when there is an infection. Professional diagnosis is essential for applying the appropriate treatment.

The specialist's recommendations include wearing light cotton clothing, avoiding wet items such as swimsuits, and drying the skin in creased areas. He also recommends showering with warm or cold water to soothe the itching. Fragrance-free moisturizers can be helpful as support, but they never replace medical treatment. Effective management of these conditions requires dermatological intervention and should not be left to home remedies.
