Pure, Natural and Organic B3 Niacinamide Serum Full 2 OZ size

I bought this on a whim...had read about niacinamide and was interested to see if I actually COULD reduce the dark spots on my hands. I have naturally dark blonde hair and medium skin tone but burn in the sun and never actually tan. So I've avoided tanning all of my life, but still developed some "age spots" on my hands. I applied this serum twice daily, morning & bedtime and in only 3 days - was amazed that the spots on my hands were lighter. It only improved over time, and my friends were so impressed they all ordered it themselves. Even a guy pilot friend used it on facial dark spots (they get a LOT of UV when flying) and his wife called to tell me that it has made a big difference for him. I began using it on some dark areas on my jawline, and inside of a week I was no longer using makeup to cover them. In fact, they are almost gone. This is a 1 oz bottle, and using it on my face, neck & hands twice daily...I ripped thru the bottle in just under a month. The price is reasonable for monthly use, but I spotted another company's 2 once bottle and ordered that instead. BIG MISTAKE! Not only did the rather spectacular lightening of dark areas stop...they actually began darkening, especially the ones on my hands. Lesson learned: when you find a product that works...stick with it! My DH & I are again using the Gia B3 and have super results: skin tightening, brightening, spots reduced, fine lines greatly reduced and more tightened & firmed facial skin. This is a wonderful serum and I just wish I could put it into my monthly subscribe & save auto shipment!

I have been using B3 Serum for over two weeks now. I wanted to wait at least that long before I reviewed it, but, truthfully, as soon as I used it the first time, I could tell that it was different from the other, more expensive products I've been using. My skin felt silky smooth, and that was without any moisturizer. I've been using this every morning and night since I received it. My skin has improved to the point where I don't even wear foundation anymore, just a tinted moisturizer, if that. The little wrinkles around my eyes are gone. What has impressed me the most is that the deep creases on each side of my nose (I think they are called "marionette lines") are going away. Every morning when I look in the mirror, they have disappeared a little more! And the other amazing improvement is that the skin on my neck is tightening! That is a major accomplishment! I've wanted to cut my hair short for a while now, but always hesitate because of my "turkey neck". I, honestly, think that by next month, I'll feel comfortable enough to go short for the summer! Several people have commented that I "look great". Even my daughter has noticed the change! I'm sold on this stuff and plan to continue to use it. I plan to get my daughter to try it for her adult acne, since some have commented that it helps with that, as well.!

I've been using this product for about two weeks. After using it, my skin has a glow appears firmer. I have been using another serum for about a year that cost over four times the price of this serum and didn't give me the results that I've already experienced with this serum. I will be ordering this product again! Update-June,21, 2016 I first reviewed this product in March and was thrilled with the results I was having. Well, I've been using it for three months and I am even more impressed! I absolutely LOVE this line of products. I have seen a dramatic improvement in my skin in this short period of time. I have had those lovely "11" lines between my brows since I was in my 30's. This product has softened them and made them less visible. Overall, it's made a big improvement in the firmness and tone of my skin, and erased fine lines I thought I couldn't get rid of. I purchase 2-3 bottles of this product a month, as I use it on my face, neck, chest and hands. I've written and asked them to make a larger size-that's how much I use and love this serum!! I really like the fact that this company is owned and operated by a women. I try to support businesses owned by women as often as possible. Try this serum-you'll be so glad you did!

I've purchased a few other B3 serums from Amazon but didn't care for them. Gia Naturals seems to do a better job at moisturizing and anti aging than the others. My teenage son uses this serum in hopes it will heal his cystic acne. He has only used one bottle and is uncertain at this time if Gia's B3 is helping his acne. He is willing to try one more bottle. I just purchased our second bottles, so we'll see. My main use for this serum is to lighten my melasma. There has not been a change to it thus far with the one bottle, but I'm hoping this second one will start to knock it out. I'll write an updated review in a month's time or so, regarding any changes in the acne and/or melasma. In general, though, this serum is a great moisturizer and I love that they use natural ingredients.

Daily use helped to lighten sun spots and in some places even eliminated them.
