Psoriasis is a genetic disease which causes chronic inflammation and scaling on skin. Psoriasis is charecterised by skin cells that multiply up to 10 times faster than normal below the surface of the skin and get deposited on the surface before they get matured. Normally, this deposition of cells takes a month time however, in psoriasis it may occur within few days. When these cells reach surface and die, raised, red plaques covered with white scales form. Psoriasis begins as a small scaling papule. When multiple papules coalesce, they form scaling plaques.
Development of thick patches of inflamed skin with a silvery scale covering starts to appear on skin. These patches are also referred to as plaques as they itch and feel sore. The commonly affected areas are knees, elbows, other parts of the legs, lower back, scalp, soles of feet, face and palms. Psoriasis can also affect toenails, fingernails, inside the mouth and soft tissues of genitals.
Vitamin D possesses different health benefits that can help treat several types of psoriasis, including scalp psoriasis.
A studyTrusted Source from 2011 found that vitamin D can strengthen the immune system. Because psoriasis is an autoimmune response, this effect could help treat the condition internally.
Topical oils and ointments for psoriasis containing vitamin D can also help treat flares. Vitamin D can slow the growth of new cells, so vitamin D oil applied directly to the flare can help thin the plaque.
"Many relatable skin disorders and abnormalities such as psoriasis, vitiligo, eczema and urticaria can be linked to vitamin D deficiency and at the very least, vitamin D could help these conditions."
"According to Dr. Dennis Gross, one of the few dermatologists to hone in on vitamin D research, it also helps minimize acne, boost elasticity, stimulate collagen production, enhance radiance, and lessen lines and the appearance of dark spots."
