Large pores on the cheeks are usually difficult to reduce if they are caused by excessive age, and can be reduced by treatment if they are caused by other reasons. As we get older, old keratin accumulates and increases in the skin of the cheeks, which gradually thickens and roughens the skin. In this case, large cheek pores are the result of aging facial skin and usually cannot be reduced in size. However, skin dehydration leads to dry and dull cheek skin, which stimulates skin oil secretion and leads to large pores. After active hydration and effective oil control, the pores will be reduced to some extent. In addition, large pores on the cheeks may also be caused by high secretion of sebaceous glands in the hair follicles, vitamin A deficiency, ultraviolet radiation, improper acne picking, etc., which need to be treated according to the specific situation, such as repairing through strong pulse light, laser fractional, etc., to make the pores smaller. In daily life, patients with enlarged pores on cheeks should eat less spicy and stimulating, fatty and greasy food, drink more water, eat more fresh vegetables and fruits, maintain a reasonable routine and avoid staying up late. In addition, women must fully remove makeup and fully clean their faces after applying makeup to prevent enlarged pores.
