Sulfathiazole is a cosmetic ingredient. Exercise caution due to limited available safety data.

Sulfathiazole is a sulfonamide-class antibiotic with well-documented skin sensitization (H315), eye irritation (H319), and respiratory irritation (H335) potential. Sulfonamides are associated with photosensitivity reactions and allergic cross-reactivity. While not absolutely banned, it is not approved for cosmetic use in the EU and would require prescription oversight if used in topical pharmaceutical preparations.
