Pores do not "open" and "close" like a door; the term refers to enlarged or clogged pores that appear more visible due to factors like excess oil, genetics, sun damage, and aging. You can reduce the appearance of enlarged pores through skincare products with ingredients like retinoids and salicylic acid, professional treatments like chemical peels and laser therapy, and lifestyle changes. Open pores are caused by a combination of genetics, aging, sun damage, excessive sebum production, and acne. As we get older, skin loses elasticity, and sun damage breaks down collagen, which makes pores appear larger. Hormonal changes and oily skin can also lead to more sebum production, which clogs pores and stretches them. #skincare #skin #science #dermatology #trending #youtubeshorts #shortsfeed #shorts
