You use the wrong water temperature
Water that’s too hot will dry your skin, while cold water won’t let your pores open, says Michele Green, MD, a New York-based cosmetic dermatologist. “Tepid water is the best water temperature,” she says. “Not too hot and not too cold.” Make sure you never, ever do these things to your skin.
You wash too often
People with dry skin might only need to cleanse once a day, and even those with more oily skin should wash twice a day at max. Any more than that could dry out your skin, making it produce even more oil to compensate, says Mona Gohara, MD, associate clinical professor at Yale’s department of dermatology. If you do wash just once, make it at night rather than in the morning. “You wash off the day’s grime and pollutants that accumulate during the day,” she says. “Not only does sun give aging, but pollutants do as well.” These are the morning skin-care routines and the nighttime skin-care routines of people with great skin.
