Dr. Taji Afytova, a dermatologist, indicates that the appearance of acne (skin rash) on the face may be due to lamblia (Giardia), ticks, or microscopic parasites living on the skin. According to her, the skin reacts to all negative changes in health, allowing parasites that enter the skin, dermis, or body to trigger follicular dermatitis, lice, scabies, and other skin diseases. Giardiasis develops when Giardia enters the intestines and can be predicted through skin reactions: rashes, hives, and flaking. Dirty hands, water, food, or household items are usually the causes. Parasitic worm infections occur in the same manner. Often, parasitic worm disease, in addition to abdominal pain and loss of appetite, is accompanied by skin inflammation. She explains that lice appear as papules, vesicles, and redness at the sites of lice bites, always causing intense itching, and in advanced cases, lead to dermatitis, pathological skin changes, and even loss of its surface layer. Skin lesions may spread beyond the scalp to the neck, back, and face. The doctor notes that Demodex microscopic mites live in the facial skin of almost everyone and become active when a person's immune system weakens. Signs of their activity include redness of the cheeks and nose, and rarely the forehead, with dry and rough skin showing small follicles that are whitish-yellow and clogged with parasites. These microscopic parasites can cause pus-filled rashes on the face. She recommends not to self-medicate in such cases but to consult a specialized doctor for treatment.
