Not like your inside organs, your pores and skin is instantly uncovered to the weather, which makes it extremely susceptible to the getting older results of environmental stressors. “Most of what we acknowledge as getting older of the pores and skin outcomes from the deleterious results of UV radiation from solar publicity,” says Richard Granstein, MD, chair of the division of dermatology at Weill Cornell Medication and a scientific advisory board member at Elysium, a dietary supplements model.
