Research Summary: Niacinamide, also known as vitamin B3, is an essential nutrient that, once inside the body, is converted into the co-factors NADH and NADPH. These co-factors are involved in numerous biochemical reactions. A deficiency of this water-soluble vitamin, a member of the vitamin B family, causes pellagra, a disease characterized by dermatitis and red lesions. Pellagra led to thousands of deaths in the United States during the first half of the 20th century until dietary supplementation with niacinamide was found to cure the condition.As we age, NAD+ and NADPH levels in skin cells decline. Therefore, supplementing the skin with...

Research Summary: Skin aging goes beyond a chronological process and also results from extrinsic factors referred to as the exposome. Hyaluronic acid (HA) is an important component of the extracellular matrix, with loss starting at the age of 25. While many studies of HA focus on its topical use, few literature reviews solely address the use of topical HA in dermatology. This review describes the various characteristics of HA-containing cosmeceuticals, with a focus on skin aging and the impact of exposome factors on HA synthesis and degradation.A review was conducted using terms such as HA, hyaluronan, topical, dermatology, cosmetic, aging...
