The causes of enlarged pores on the face are considered to be related to dehydration, skin aging, and overproduction of sebaceous glands. 1. Dehydration: When the dermis layer of the skin lacks moisture, the epidermal cells will begin to shrink, which in turn will result in large pores and wrinkles. 2. Skin aging: With age, the skin’s metabolism slows down and the lack of elasticity of the skin makes it flabby and insufficient to support the surrounding pores, resulting in enlarged pores. 3. Excessive sebaceous gland secretion: Patients may have abnormal hormone secretion in the body due to irregular life, frequent late nights and other factors, causing excessive sebaceous gland secretion, which can make the skin pores enlarged and clogged. There may also be other reasons for enlarged pores on the face, if necessary, go with the doctor for further examination, and give targeted treatment and therapy.
