Over the past decades, it has been common practice to use zinc in creams and salves for treating various skin disorders. Zinc has wound-healing, antibiotic, and anti-inflammatory properties that make it useful for such purposes. In a review article that is published in International Journal of Molecular Sciences, the authors look closer at zinc’s role in skin health. They also look at whether zinc supplementation may positively affect eczema, acne, psoriasis, herpes, and other skin diseases. The authors also address the fact that around one third of the world’s population is zinc-deficient.

Atopic dermatitis is a common skin disease. Our modern lifestyle plays a role, and vitamin D deficiency in early childhood also seems to increase the risk of developing the disease later in life, according to a study that is published in World Allergy Organisation Journal. The health authorities recommend that pregnant women and small children take a vitamin Dsupplement.

Psoriasis is a chronic inflammatory skin condition. Some patients also develop rheumatoid symptoms and metabolic disturbances. The diet plays a major role, and psoriasis patients appear to have fewer polyunsaturated omega-3 fatty acids in their red blood cells. According to a Polish study that is published in Nutrients, psoriasis patients seem to have an entirely different lipid profile in their red blood cells, which promotes inflammatory processes and increases the severity of the disease.

In the case of wounds or skin lesions, an active form of vitamin A regulates how stem cells initiate healing processes and produce new skin. This was demonstrated in a study from Rockefeller University that is published in the journal Science. In the future, researchers plan to look closer at how active vitamin A can be used to regulate stem cells as a way of preventing and treating skin cancer.

Photodynamic therapy is a kind of light therapy that is used to treat skin cancer, psoriasis, and other skin diseases. According to a review article published in Nutrients, vitamin D supplementation can improve the outcome of the treatment. In fact, vitamin D appears to have several positive effects on skin health. Taken in large doses, the vitamin can even repair skin damage caused by sunburns.
