Dyes and skin irritation

Textile dyes are one of the most overlooked sources of skin irritation in clothing. Synthetic azo dyes, which account for 60-70% of all dyes used in the textile industry, can break down into aromatic amines — some of which are classified as carcinogenic.

Dark-colored garments typically contain higher concentrations of dye, which is why dermatologists often recommend lighter-colored clothing for people with sensitive skin or eczema. The dye molecules can migrate from fabric to skin through sweat and friction.

Natural dyes derived from plants, minerals, and insects offer an alternative, though they come with trade-offs in color fastness and cost. Some brands now use low-impact synthetic dyes that are free from heavy metals and aromatic amines.

If you experience unexplained skin irritation, consider whether it correlates with specific garments — particularly new, dark-colored, or brightly colored items. Washing before first wear and choosing certified products can significantly reduce dye-related skin reactions.
