Infectologist Hernán Rodríguez advised against using colored disinfectants, such as iodine tincture and mercurochrome, to treat minor wounds, arguing that these products can hinder the identification of possible skin complications.
In an interview, the specialist explained that the most appropriate procedure for cuts, scrapes, or superficial lesions is to initially wash the area with plenty of soap and water and keep constant observation of the wound's evolution. "Preferably, first wash with soap and water and observe," Rodríguez stated, warning that inflammatory conditions can develop rapidly, within hours.
The doctor highlighted that products with intense coloring can hide early signs of infection, such as redness, swelling, or skin changes. "Often they do not allow you to see the process of the condition. An inflammation can set in, and because of the product's color, you cannot visualize it well," he explained. Additionally, he mentioned that certain antiseptics form a dry film on the skin's surface, favoring the accumulation of dirt or debris, which can complicate healing.
Rodríguez warned that even seemingly small wounds can worsen quickly if there is a bacterial infection. "Sometimes a person says 'a pimple came out at night' and by morning they already have a severe inflammatory condition, swollen, red, hot, painful, and even with fever," he reported. The infectologist reinforced the importance of monitoring symptoms such as intense pain, local heat, inflammation, or fever and seeking medical attention if the condition worsens.
The recommendations are aligned with first aid practices, in which proper hygiene and early detection of infectious signs are considered essential to prevent major complications.
