Skin fungal infections are caused by fungi that invade the outer layer of the skin. Common types include athlete's foot, ringworm, and jock itch. These infections can lead to symptoms such as redness, itching, and peeling skin. They thrive in warm, moist environments, making areas like feet and groin particularly susceptible. Treatment typically involves antifungal creams or medications, which help eliminate the infection. Maintaining good hygiene and keeping the skin dry can prevent these infections. It's important to consult a healthcare professional if symptoms persist or worsen, as some infections may require more intensive treatment.
