Yes, researchers say dry skin can be inherited. According to a study, mutations in genes that control the production of the protein filaggrin, which plays a role in forming and hydrating the skin barrier, can cause several skin conditions. People with these mutations, estimated to be about 10 percent of the population, suffer drier skin and have a greater chance of developing eczema. Atopic dermatitis is a common type of eczema.
If you’ve always had dry skin or if it runs in your family, it’s essential that you’re diligent with daily moisturization. “Look for ceramides and lipids in moisturizers, which help build and reinforce the skin barrier,” says Joshua Zeichner, MD, the director of cosmetic and clinical research in dermatology at Mount Sinai Hospital in New York City.
