A good skin-care routine isn’t only about which serums and moisturizers you choose to apply — establishing good habits at home is an equally crucial step. And with many people spending more time at home than ever before during the COVID-19 pandemic, now is the perfect time to assess your environment and make improvements where you can.Dryness is your skin’s worst enemy. “When the skin lacks proper hydration, it triggers various reactions, one of them being more oil production and more breakouts,” says Annie Gonzalez, MD, a board-certified dermatologist with Riverchase Dermatology in Miami BeautyFixMedSPA. This is exacerbated in winter months due to dropping humidity levels outside and artificial heat pumping through your house. Your move: Add a humidifier to introduce moisture back into the air.
