Dermatology
A lipid-soluble synthetic red-orange carotenoid which humans cannot convert to vitamin. It deposits in the skin, imparting a pink-orange hue, and has been marketed as a tanning agent under various names— without FDA approval—often in combination with beta-carotene.

Food industry
Canthaxanthin is produced naturally by some plants and marine animals; it is approved by the FDA as a dye for soups, fruit drinks, catsup, salad dressings, tomato juice, and others, and may be added to animal feed to “enhance” the colours of chicken skin, egg yolks, rainbow trout flesh and other foods.

Fringe oncology
Canthaxanthin stimulates the immune system and enhance vitamin E’s antioxidant activity; it may reduce the incidence of spontaneous cancer in experimental animals.
 
Toxicity
Allergic reactions, canthaxanthin retinopathy (deposits in the macula), hives, itching, hepatitis and aplastic anaemia.
