What is Niacinamide?
Niacinamide (sometimes referred to as Nicotinamide) is a Vitamin B3 derivative. You may notice that it’s listed low in Geologie’s formulas; it may be present at only a small level, but it packs a real punch. In fact, this small but mighty molecule is key to healthy skin. Bear with us a bit as we dive into Niacinamide’s essential role in the biochemical processes your skin—actually, most cells—rely dearly upon.
A small molecule with high skin permeability, Niacinamide promotes metabolism and the synthesis of dermis lipids and ceramides. How? The exact biochemical mechanism isn’t yet nailed down by skincare scientists, but it’s theorized Niacinamide’s anti-aging properties have to do with the molecule’s role in NAD+/NADH redox, a biochemical reaction essential to cell health. Sparing you the details of the biochemical cycles involved, it’s enough to say that the creation of molecule NADPH is predicated upon successful NAD+/NADH redox. NADPH is a cofactor in the synthesis of fatty acids, a component of protective sebum. To draw a generalized and overarching connection, Niacinamide is essential to the creation of balanced sebum. Niacinamide is also known to promote the production of glycosaminoglycans (ahem, Hyaluronic Acid), helping to boost your natural dermal extracellular matrix.
What does Niacinamide mean for skincare?
Due to its essential role in the production of extracellular glycosaminoglycans and free fatty acids, Niacinamide may be said to be an anti-aging active. By boosting the health of your sebum, Niacinamide helps lower the incidence of wrinkles and fine lines, a result of tired and less elastic skin. This mighty molecule may help also help with skin tone evening and whitening by impeding melanin overproduction. Suffice to say, while Niacinamide is not directly a building block of healthy skin, it is essential to the creation of those building blocks.
We added a dash of Niacinamide to the Repairing Night Cream and Nourishing Eye Cream to ensure that your skin has all it needs to recover and repair while you sleep.
