Sometimes your skin is worth splurging on and this winter might just be one of those times. Winter is all about hygge and vegging out, says Mona Gohara, MD, dermatologist in Danbury, Connecticut, but "even though there isn't a lot of sun exposure, the phone and computer are damaging the skin," she says. She likes this two-step system, which includes a daytime serum and night cream for round-the-clock protection. The serum "helps to protect against light that comes from computers, cell phones, billboards, street lights and other sources during the day" while the night cream "supports the cell repair cycle that naturally occurs at night."
