What are the best natural fabrics for sensitive skin?

For sensitive skin, the best natural fabrics share key properties: smooth fiber surfaces that minimize friction, hypoallergenic compositions, and freedom from chemical irritants. Tencel lyocell tops the list for many dermatologists because its fibers are microscopically smooth, naturally antibacterial, and produced without harsh chemical residues. It is also less likely to harbor dust mites and allergens compared to cotton.

Mulberry silk is another excellent choice, particularly for sleep. Its amino acid-rich protein structure is naturally gentle on skin, and its ultra-smooth surface creates minimal friction — reducing irritation, redness, and sleep creases. Silk also does not absorb moisture from your skin the way cotton does, helping maintain your skin's natural hydration levels. For those allergic to lanolin (a common wool sensitivity), alpaca wool is a standout alternative. Unlike sheep wool, alpaca fiber is completely lanolin-free, making it suitable for people who cannot tolerate merino or other wools.

Organic cotton is also a strong option, especially GOTS-certified organic cotton that has been produced without pesticides, synthetic dyes, or chemical finishes throughout the entire supply chain. The absence of chemical residues is often more important for sensitive skin than the fiber type itself. At ONDU, Reprise Activewear's Tencel pieces, Promeed's silk pillowcases, and PAKA's alpaca garments are all excellent choices for skin-conscious shoppers.
