Niacin, also known as Vitamin B-3 is found in many foods, including yeast, meat, fish, poultry, milk and eggs. The benefits for the internal consumption of niacin are astronomical. It is scientifically proven to help treat heart disease, diabetes, cholesterol, and more. Topical application of products that contain niacin and niacinamide (which is a derivative of niacin) has also proven to have incredible effects. Niacin is found in all cells and it plays an important role in energy production. Thus, it is present in the organs that are metabolically active like the brain, heart, and liver.
In regards to skin care, Niacinamide has the ability to treat skin conditions including aging skin. It is anti-inflammatory which makes it effective in the treatment of acne. It is also beneficial against skin conditions such as psoriasis and rosacea. Studies have shown that 4% niacinamide gel can improve the symptoms of acne. In regards to rosacea, one study showed rosacea patients treated with niacinamide resulted in a diminished reaction to irritants. 26 out of 34 patients studied had a dramatic improvement in their skin.
Niacinamide is amazing for young skin, but it’s a miracle worker for more mature skin. There is evidence that it stimulates cells to produce more collagen. It’s also great for excessive dryness because it prevents moisture loss. It protects the skin by providing a safe occlusive barrier between skin and the environment. This ingredient does not feel heavy or greasy. Most importantly, niacinamide increases the production of ceramides which are lipids in the outer layer of the epidermis. Ceramides form a protective barrier against water loss. It will soften the look of fine lines and wrinkles. It stimulates circulation in the dermis which increases blood flow and increase vital nutrients to the skin, radiance, and overall skin health.
But what about those ugly age spots and hyperpigmentation that many suffer from due to sun exposure and other factors? Niacinamide in concentrations of 4% helps lighten areas of pigmentation. It reduces blotchiness, improves skin texture, and evens out skin tone.
Is it safe? According to a study published in The International Journal of Toxicology, niacinamide is not toxic or carcinogenic. This was tested on levels higher than those found in any cosmetic product. More importantly, it does not sensitize the skin or cause irritation in most people. It is classified as a low hazard cosmetic ingredient by The Environmental Working Group.
In a clinical study, after just four weeks of Niacinamide use, users saw water loss reduction by 24%, Pigmentation decrease by 68%, and increase of fatty acids by 67%, increase of ceramide production by 34%, fibroblasts production by 20%, collagen production by 54%.
Clearly, the studies show it produces great results; Niacinamide is an ingredient for those who want to go above and beyond in their skin care.
