It is usually difficult to recover from enlarged pores, but you can choose to improve them with medical treatments such as photorejuvenation or fractional laser and fractional radiofrequency treatments. The main reason for enlarged pores is the increase in the accumulation of old skin keratin, which causes the facial skin to become thick and rough. It may also be because the skin can not smoothly absorb moisture and maintenance ingredients, and thus become dull and dry, stimulating oil secretion, so that the pores become enlarged. In this case, you can choose to use some moisturizing and restorative topical creams, or you can choose to use laser treatment to stimulate the rearrangement of collagen under the skin to reduce pore size. When your pores are already enlarged, you need to pay extra attention when choosing facial cosmetics and skin care products to avoid using products that can irritate your skin.
