Niacinamide is an old time favourite ingredient in the green beauty industry. The niacinamide properties and the high tolerability even on sensitive skin, made it a star vitamin, widely used in skincare. It is naturally derived from nicotinic acid found in many cereals and brewer’s yeast. Once isolated, it undergoes a chemical reaction to become Niacinamide, otherwise known as vitamin B3 or vitamin PP.
Squalene, to me, represents the perfect natural alternative to the most common ingredient in skincare, “paraffinun liquidum”which is from a chemical point of view a hydrocarbon, same as the squalene, which comes in liquid form due to its unique structure. I use the stable version which is called squalane.
After last week’s post, it is the time to focus on what not to use during pregnancy and breastfeeding. Some of the studies on ingredients I have found are not complete enough to establish a proper negative list. In my opinion, while some conclusive data arrives, it is better to avoid them completely.
