“Multiple studies have pointed to the antimicrobial properties of a special European silk fabric called DermaSilk,” Dr. Peterson says. Dermasilk differs from regular silk in that it’s free of sericin, a protein produced by the silkworm. Sericin and other protein or bacteria can aggravate eczema and other skin conditions, so antimicrobial agents help skin stay clear and free of irritation. “One particular study showed improvements in patients with the skin condition eczema who used Dermasilk, but not in those who used cotton,” she adds.
Additionally, because it is composed of long, smooth, natural fibers tightly woven together, silk helps decrease skin’s loss of moisture and is better tolerated than other fabrics by people with sensitive skin, Peterson says. Stay away from synthetic fibers, wools, and even some cottons that may contain small, stiff, woven fibers that can cause irritation.
