The claims for niacinamide are pretty substantial and they are backed up by studies and good science. Studies have shown that 2% in a facial moisturizer can increase skin's keratin, ceramides, and barrier lipids which results in a reduction of transepidermal water loss and an increase in collagen synthesis. 2% can result in a 23% reduction in sebum production and pore diameter. It can reduce hyperpigmentation of age and sun spots. And it can reduce the damage from environmental causes, which reduces the irritation, inflammation, and skin redness from things like the sun, cold, or weather as well as application of straight SLS. Even at 5%, there's a lack of irritation and redness on our faces ('cause sometimes niacin can make our skin flush, but not at 2% or 5%). It can reduce the appearance of fine lines and wrinkles and decreases skin blotchiness and "pebbling" or roughness on facial skin. All of these great things can happen in a short period of time. In one study, all of these results were seen within 12 days (the first time they checked, so it could have been a shorter period of time) and continued to work with application of the moisturizer daily.
This seems like a great inclusion for just about every skin type from wrinkled to oily to normal!
Take a look at this article on the awesome power of niacinamide! It's even more amazing than you think!
I've found this ingredient in a few locations - at Lotioncrafter and MakingCosmetics.com - and it's not that expensive considering the suggested usage is 1% to 6% (check with your supplier for their specific recommendations) As the studies I've quoted above used 2% in their products, it seems that this is a good amount for our products!
