👉 Rissoacea is a type of skin condition characterized by redness, swelling, and irritation primarily affecting the face, neck, ears, and scalp. It typically begins as small blisters or vesicles that may develop into larger lesions over time. Risiaceas can be caused by various factors such as acne, fungal infections, or allergic reactions. The severity of the condition varies depending on the individual's age, gender, skin type, and underlying health conditions.
