Everyone would like to have clearer pores, and for those with acne-prone skin, this becomes even more important. There is a lot going on in and on our skin daily that can cause our pores to become clogged — including natural oil production and buildup of dirt and dead skin cells. Clogged pores are one of the leading causes of pimples. 

Dermatologist Anna Karp told Byrdie that one of the uses of tretinoin is to achieve clearer pores. "Acne is a multi-factorial disease with increased dead skin cells filling up in our pores, causing comedones. Bacteria often colonize the pore, leading to worse acne," she explained. Tretinoin prevents the clogging of pores by getting rid of dead skin cells. It also helps exfoliate the skin, increases collagen production, and escalates your skin cell turnover rate, all of which help with the appearance and cleanliness of your pores.

Tretinoin is also great for those looking to build a skincare routine for aging skin. In addition to boosting collagen production, which is key to achieving youthful-looking skin, tretinoin is also great at reducing the appearance of fine lines and wrinkles. According to Lortscher, the product really is the best topical skincare when it comes to fighting the signs of aging.
