You’re more stressed out
‘Unfortunately, the holidays and all the expectations surrounding them increase our stress level,’ says Dr. Lain. ‘An increase in the stress hormone, cortisol, can have deleterious effects on the skin, again causing premature aging and poor tone and texture.’ He recommends incorporating some rest and relaxation time now and then, whether it’s watching a movie at home or having a spa day; that will give you (and your skin) a chance to recoup.
