In fact, there are two main reasons for the pore coarseness. One is the relatively large amount of oil secreted by the sebaceous glands of the skin, which makes the caliber of the "oil pipe" for delivering sebum coarser, and the natural pore will be coarser. If the sebum is blocked in the hair follicle, too much sebum will block the pores, and the pores will be larger. Generally, the areas with strong sebum secretion are mainly in T-zone, so the skin's T-zone pores are really easy to appear bulky.<br>The other reason is that the connective tissue of dermis is loose and deformed, which makes the connective tissue around the hair follicle unable to maintain elasticity, so the hair follicle expands and causes the permanent problem of pore bulkiness.<br>
