There are approximately 200,000 pores on the face. Due to hormones, men have larger pores and more active sebum secretion than women. It is an important organ involved in metabolism that excretes sebum, sweat, and waste products, but dryness, lack of maintenance, disturbances in the autonomic nervous system and eating habits, lack of sleep, etc. can cause pores to open and affect the appearance. In addition, a mixture of dead skin cells, sweat, and sebum can cause keratin plugs that clog pores, and the tips of these keratin plugs can oxidize and turn black. Additionally, as pore problems progress, the open pores may become sagging or become connected in a band-like manner, making them unsightly. At our clinic, in addition to photofacials, chemical peels, and Dr. Eri's Pico Skin Rejuvenation, we also use home care to eliminate pore problems in a short period of time.
