Many researchers have described the dermatological (skin) symptoms caused by a deficiency of Vitamin B6, particularly in relation to the body's use or metabolism of essential fatty acids. People suffering from toxic and allergic skin conditions, including psoriasis and eczema, often show a deficiency of Vitamin B6. A deficiency of Vitamin B6 can cause atrophy or wasting of the epidermis, hair follicles and sebaceous glands. It appears that Vitamin B6 may act directly on the sebaceous glands and is involved in the correction of defective fatty acid metabolism.
Given the role of Vitamin B6 in the metabolism of essential fatty acids in the body, it appears that the combined use of Vitamin B6 and essential fatty acids such as in Rosehip Oil and Evening Primrose Oil have a good synergistic effect on various skin complaints.
