Pure Niacinamide Powder for Skin Care (Vitamin B3) DIY Niacinamide Serum, Niacin Powder (1 Ounce / 28 Gram) Cosmetic Grade

I purchased this for my DIY face serum and it worked wonderfully! When I run out, I will definitely be purchasing from this company again. I’ve bought other products from Talsen in the past, and they’ve all been of excellent quality.

When first trying to use this powder directly from the pouch, it was difficult to measure out the appropriate amount because it's much a more powdery consistency than the niacinamide powder I used to buy from The Ordinary, and tends to clump more easily. (Thought I'd try a different brand this time due to the number of complaints that The Ordinary has recently been shipping products too close to their expiration dates, and their jar of niacinamide powder takes a long time to use up even with a more extended expiration date.)I'm glad I'd saved the spoon and the jar from my last niacinamide powder order from the Ordinary, because the Talsen product was too difficult to scoop in smaller quantities, especially when trying to spoon it directly from the pouch. So I decanted it into the old jar from The Ordinary, and it was a bit easier to scoop, but due to it's super powdery texture, it kept clumping together into a full spoonful, and not the quarter-spoon measurement recommended by The Ordinary. Maybe just taking a pinch with your fingers might work better. The Talsen package gives no usage/measurement information, so if you've never incorporated powdered niacinamide into your skincare routine, you may want to visit The Ordinary's website for instructions.JUNE 2024 UPDATE: This Talsen product may well come from the same source as The Ordinary's niacinamide powder, but whatever the case, it has become even more clumped over time, though I keep it in a tightly sealed jar, in a cool, dry cupboard, and it does not come into contact with moisture. I'm finding it impossible to measure out the correct amount. Even though The Ordinary's niacinamide powder has a less powdery texture, it dissolves more easily into my serums than the Talsen, so I'm going back to The Ordinary.

Does not dissolve.......It’s also gave me chemical burn on my face.Do not recommend to use it for cosmetic usages.
