First described in the 18th century, Casal's necklace, or Casal's collar, is a distinctive red and hyperpigmented rash around the neck, serving as a tell-tale sign of pellagra, a severe nutritional disorder. Historically, it was named after the Spanish physician Don Gaspar Casal, who first identified the syndrome among the poor population in Spain in 1735.

Historically, pellagra has affected millions, often in populations relying on corn as a staple food, and is famously characterized by the "3 Ds." An understanding of what are the three main symptoms of pellagra—dermatitis, diarrhea, and dementia—is crucial for early diagnosis and treatment.

According to research aggregated by Consensus, deficiencies in vitamins such as C, D, A, and B-complex, as well as minerals like zinc and copper, are a well-known cause of various skin rashes and cutaneous changes. These nutritional shortfalls can trigger a range of dermatological symptoms, often revealing themselves through visible skin issues that can sometimes be mistaken for other conditions.

While extremely rare, isolated case reports and recent medical literature suggest a link between caffeine consumption and Fixed Drug Eruption (FDE). This specific type of skin reaction involves recurring lesions in the same location after re-exposure to a trigger.

While a very serious allergic reaction to creatine is rare, it can manifest as a rash, itching, or swelling. This article explores the relationship between creatine supplementation and skin rashes, looking at genuine allergies, potential impurities, and other factors that could be the real culprits behind your skin irritation.

While vitamin B12 is crucial for health and typically very safe, high doses—particularly through injections—have been reported to cause skin reactions like flushing. This reaction is generally considered uncommon, but understanding its causes is important for those on high-dose supplementation.

According to the World Health Organization, it is estimated that around 2 billion people worldwide are deficient in zinc due to inadequate dietary intake, making it a common nutritional concern. Understanding what are the signs of not enough zinc can help you identify a potential deficiency and take proactive steps to address it.

A 2004 placebo-controlled clinical trial demonstrated the significant superiority of topical vitamin B12 cream in reducing the severity and extent of atopic dermatitis. This provides compelling evidence for its use in certain inflammatory conditions, leading many to ask: is vitamin B12 good for skin rashes caused by other factors?

While biotin deficiency is very rare in healthy individuals who eat a balanced diet, it can lead to a variety of symptoms affecting the skin, hair, and nervous system. Understanding what happens when biotin is low is crucial for recognizing the signs and seeking proper treatment if a deficiency is suspected.

Some foods contain compounds related to urushiol, the toxin in poison ivy. While skin contact is primary, ingesting these food-related compounds or other inflammatory foods can potentially worsen rashes for highly sensitive individuals.
