Uneven skin on the face may be related to acne, rosacea or facial cornified lupus. 1. Acne: When there is inflammatory stimulation of the sebaceous glands of the hair follicles on the face and forehead, pimples, inflammatory papules, pustules or nodules may appear, and cysts and scarring may also form, resulting in the unevenness of the facial skin. 2. Rosacea: Formerly known as rosacea, a persistent flushing reaction may appear in the middle of the face. If the disease continues to progress, papules and pustules may appear on top of the erythema, and the opening of the hair follicle may be enlarged. 3. Facial milia: lesions may appear rapidly on the face, cheeks, etc., presenting round papules, red or purplish red, sometimes there may be small yellow pustules or scaly scabs at the top of the papules, and the papules may gradually subside, leaving atrophic scars to form pits. When the face is uneven and there are pimples, you need to go to the dermatology department of the hospital in time to find out the cause and follow the doctor’s instructions for treatment.
