Sulfur dyes are predominantly black, brown, and dark blue. [1] Red sulfur dyes are unknown, although a pink or lighter scarlet color is available.
The dye itself can be directly absorbed through the skin and into the bloodstream. [14] The stratum corneum (the outermost layer of skin also called the “horny layer”) contains a “lipid domain” that allows the dye to pool and provide opportunity to diffuse into the body. [14] Some hair dyes can also irritate the skin with prolonged ...

In traditional skin treatment, elemental sulfur was used (mainly in creams) to alleviate such conditions as scabies, ringworm, psoriasis, eczema, and acne. The mechanism of action is unknown—though elemental sulfur does oxidize slowly to sulfurous acid, which is (through the action of sulfite) a mild reducing and antibacterial agent. [66] [67 ...
