Oily skin and age can lead to larger pores. Our bodies naturally produce an oily substance called sebum to keep the skin from drying out. Skin swells when this oil and dead cells collect in your skin, making your pores appear larger.
As you age, skin is more lax, thus contributing to the appearance of large pores. Sun damage can also negatively affect the appearance of pores due to the loss of elasticity.
There are many cosmetic treatments available at Trillium Creek Dermatology to shrink the appearance of your enlarged pores.
