This month’s ingredient is Niacinamide. Niacinamide has a breadth of benefits, including restoring suppleness and Inhibiting the transfer of melanosomes (interrupting the process that causes irregular pigmentation).
What is it exactly?
Niacinamide or Niacin are forms of the Vitamin B3 Vitamin B3 is found naturally in many foods that include yeast, and also in root vegetables. Niacin and Niacinamide are also found in many Vitamin B complex supplements with other B vitamins. The use of vitamins topically in the past have been shown to not be very effective, however Vitamin B3 has been one of a very few exceptions in clinical studies.
How does it work?
You skin contains enzymes called NADH and NADPH. These enzymes help keep your skin cells energized and producing lipids. In turn these lipids are responsible for cell growth. When we have sufficient amounts of these enzymes it acts as a barrier for our skin against external environmental factors such as UV or pollutants. Just like so many other things as we age our body produces less of these enzymes. Niacinamide slows down and even reverses the rate in which these enzymes decline. Secondarily, Niacinamide seems to have some antioxidant and anti-inflammatory properties.
What studies have shown
There have been many studies that show their versatility of Niacinamide. Its anti-inflammatory properties and boosting of the skin’s natural barriers can help many skin conditions such as acne and rosacea. Some studies show it increases the skin’s productions of ceramides which helps improve skin hydration. Others that the improvement to the skin’s natural barrier helps mitigate the effects of UV light. Another study shows it to significantly improve many signs of aging such as fine lines and wrinkles, hyper-pigmentation, skin texture and blotchiness.http://www.smartskincare.com/treatments/topical/niacinamide.html
