Enlarged pores occur most often because of genetics and age. Those who have naturally thick and oily skin tend to have larger pores. As we age, sun damage can cause the pores to dilate over time.
Microneedling, also called collagen induction therapy, is a facial treatment offered for enlarged pores. As the microneedling pen stamps over your skin, it creates micro-point punctures in the skin, the majority of which are simply pushing your pores open temporarily. This is perceived by the body as damage, which stimulates the release of growth factors that trigger the production of collagen and elastin. Your skin reacts to any injury by initiating the healing process. You encourage your skin to continue healing through this micro-needling process.
