Enlarged pores can be due to physiological reasons, such as eating oily food and not cleaning properly. It may also be caused by pathological reasons, such as acne. It is recommended that the patient be treated according to the specific cause under the guidance of a doctor. 1. Physiological causes: For enlarged pores caused by physiological factors, patients need to change their lifestyles, i.e., patients should try to eat a light diet in their daily lives, keep their faces clean, and use cleansing products with good oil control. 2. Pathological causes: Acne is the most common cause of large pores caused by pathological factors. Patients can be treated by limiting oil and sugar intake, using topical medications such as retinoids and benzoyl peroxide under the guidance of a doctor, and also using physical therapy such as laser therapy. For patients with large oily pores, if they are self-conscious of the aesthetic impact, it is recommended that they go to the hospital in time for examination and standardized treatment under the guidance of a professional doctor.
