  Good Product & Company

  I recently read how intake of B3 (as Niacianamide) can cut the incidence of common skin cancers by a third. As well, it seems that topical application of Niacianamide can undo sun-damage in the skin. I'm sure one could ingest this product, but I didn't buy it for that (I worry about dosage amounts), but rather, I bought this so I could add it to various lotions, shampoos, hair-conditioners, etc., to help protect and just generally help sun-damaged skin. I'm impressed with this product and company. If you buy Niacianamide as tablets, there are a lot of other ingredients (binders, etc.). This is, evidently, pure and is water-soluble, so it readily mixes with any water-based liquid, such as lotions, shampoos, etc. I recommend for anyone interested in making home-made (and thus, purer and cheaper) skin products that evidently have a beneficial effect on sun-damaged skin. I like that it's not expensive, and you get a lot when you buy it in bulk. I like also that it comes in a no-nonsense convenient re-closable foil packet, so it's easy to use, easy to close, put-away, and store.

  Great quality and works fast

  This niacinamide powder is excellent and very pure. It dissolves well, has no bad smell, and works quickly when added to my skincare mix. I've noticed smoother skin and less irritation after just a few uses. The quality is consistent, the price is good, and a small amount goes a long way. I'm very satisfied with this product.

  Awesome to use in face products!

  I love this stuff for what it does to my skin! I use it topically in my face products. I mix it in toners and lotions (sometimes even my spf). Topical niacinamide has been proven to be a somewhat effective anti-aging/acne treatment in numerous studies (so have vitamin c and green tea). I like it because i have sensitive skin but I find it calming and it definitely fades skin discoloration over time. I also feel like it makes my skin *behave* better (stays better moisturized but not greasy), if that makes any sense. I know products from Olay and Cerave (to name a few) contain niacinamide but they break me out so I can't use them.Most studies used it at a 5% concentration (so 1 to 20 ratio *thank you Viking Fan) and it works best at a PH of 5-6 (so don't bother mixing it with AHA or BHA). You don't have to mix it with anything special; you can just mix it with water and use it as a toner (if you don't use a preservative you should make it every day lest it go bad on you). Keep in mind, if you go any higher than 5% you may get a flushing effect--in fact you might get a flushing effect even at 5% if you're sensitive to it (some people are and while some people eventually grow more tolerant some people just can't use niacinamide without a bad reaction).Lots of people like to mix it with withN-Acetyl Glucosamine Powder (25 gm) Reduces hyperpigmentation Improves skin tone.To give you some ideas of how to use it, this has always been a popular recipe on Makeupalley dot com:"* 85 ml distilled witch hazel (Boots brand right now, which contains approximately 14% alcohol, as such, no preservative is required)* 10 ml vegetable glycerin* 5 g (approximately 1.5 teaspoons for those who don't/won't weigh it out - I prefer to weight it) niacinamide powder."--(i think it's "JoshuaP's" recipe)This is another Dropy reviewer's recipe ("Gattu"):5 tsp. rose water10 drops of licorice extract½ tsp. Glucosamine (5%) --BulkSupplements½ tsp. Niacinamide (5%) --Nature and Nurture½ tsp. Glycerin½ tsp aloe gel ( I almost took 1 tsp)2 tsp vitamin C ester powder (20%) --BulkSupplementsOf course you can also just mix it with water and spray or pat on your face... Sometimes i've mixed it with other products and toners (like Thayer's Witch Hazel). Sometimes i've even just scooped a bit out and mixed it with the daily squirt of my face lotion or SPF (very unscientific, of me). This stuff dissolves really well, so its really versatile.
