Vitamin B is no small time player in the high stakes game of the beauty. Just take the case of pellagra for example. Pellagra is a life threatening skin disease characterized by dementia, diarrhea, and dermatitis that results from a niacin (B vitamin) deficiency. In the early 20th century in the United States pellagra plagued thousands of people in the South and Midwest. The condition was thought to be contagious until investigators discovered the underlying nutritional deficiency.

Even today, the importance of vitamin B is cultivating new roles in the world of beauty. Dermatologist Leslie Baumann, MD forecasts topical vitamin B and its multiple derivatives as key ingredients in future anti-aging products. For example, one derivative of the B vitamin niacin, nicotinamide, has been shown to improve the ability of the epidermis, the upper-most layer of the skin, to retain moisture. One study reports that topical nicotinamide, when applied to the skin for six days reveals softer, smoother skin with less dryness and flakiness, and a reduction of fine lines. Even more promising is its anti-cancer influences. For instance, when applied to mouse skin, topical nicotinamide produced a 70 percent decrease in ultraviolet-induced skin cancer.

Niacinamide, another byproduct of vitamin B, serves as an effective skin-lightening agent. In one clinical investigation, patients with hyperpigmentation applied a moisturizer containing five percent niacinamide. Four weeks later, computer analysis of the hyperpigmentation and skin color revealed a decrease in hyperpigmentation along with an increase in skin lightness. Topical niacinamide also exhibits anti-inflammatory properties, which makes it a potential treatment for acne, rosacea and any blistering-type disease.
