  Good value for a decent product as far as I know.

  I left a bad review of this product based on faulty information from AI. In the interest of honesty and fairness I want to delete that bad review and the only way I know to do that for sure is to overwrite it, which is what I'm doing.

  With water or topical

  Best Vitamin c I've tried. Minimal taste when mixed in water. I've also mixed it into my moisturizer and used it on my scars from old pimples. Helped alot.

  Hello beautiful skin!

  I make my own vitamin C serum with this stuff and it is so good for my skin. Vitamin C is involved it the stimulation and production of collagen in the skin and you can not get enough of it in the right places through diet alone.Buying high quality, designer C serum is always an option, but, it will cost you an arm and a leg and it will have preservatives in it and who knows what else? When you make your own, it is always fresh, extremely effective, you always know what is in it and it is so affordable you can use it all over if you wish.I make a fresh batch every 3 days and keep it in a dark spray bottle container. Vitamin C is extremely fragile and will turn quickly. If that happens you will actually be putting something on your skin that will CAUSE the very damage you are intending to prevent and reverse in the first place. So keep it fresh, never trust products that have vitamin C added unless they are costly and have a reputation for being good quality. Vitamin C is quite a buzz word for advertisers and marketers of products but does absolutely no good for your skin if it is not preserved properly and packaged correctly.Vitamin C serum needs to be made with purified water if you are using water as the base. Some other options are witch hazel or rose water. You can also add a drop or two of glycerin to give it a little slip and spread-ability. Always store it in an air tight container to prevent oxidation and make sure the container is a dark glass or plastic to protect it from light.Depending on how strong you want it the following guide will give you the measurements for the right formula for your needs or tolerance.5% serum - 1/4 tsp Powder to 4 & 3/4 tsp base10% serum - 1/4 tsp powder to 2 & 1/4 tsp base15% serum - 1/4 tsp powder to 2 & 1/8 tsp base20% serum - 1/4 tsp powder to 1 tsp baseI jumped right into the 20% strength right away twice a day. It was a bit strong at first. Stings a little but I wanted maximum results right away. My skin responded the very first day. I woke up with brighter skin, tighter pores and a smoother feel to the touch. My skin was glowing! It keeps getting better but now I only use it every other morning as I now use Retin A at night.The spray bottle makes it easy to spray on my tummy, bum and thighs. If you use a dermaroller for stretch marks, cellulite or scars anywhere on the body, vitamin C serum is a must to aid in the repairing process. I love how the backs of my thighs are tightening up and this stuff is helping.Don't forget the under arms. I used to have issues with under arm odor even if I was freshly showered. I learned that this is a p.h. issue and as soon as I started squirting a little serum under my arms every morning it went away. I recommend a weaker strength for this so you don't sting your pits!I love this stuff. I wish I would have known of the benefits for use on skin years ago.

  Fantastic for Multiple Uses

  This is pure ascorbic acid, so you get the best results in whatever way you are using it. I purchased this to take internally (about 4,000 mg/day) and it is GREAT. I put it in water 3 times a day and get my full vitamin C intake to keep my immune system functioning properly. Yes, it's tart, but hello - that's what vitamin C tastes like! I supposed I could put it in juice like I do for our son, but I'm on a no sugar diet/healthy foods so that's not an option. I am not into bitter or tart flavors, and I can deal with this, so most people will probably find it very tolerable if they have to take it in water only like myself.I also used to use a vitamin C face powder with my moisturizer (which is a combination of natural oils I make myself) and was almost out of the vitamin C face powder. I checked the ingredients and found out there were a number of ingredients that I didn't want to put on my skin (what goes on your skin goes INTO your skin and then into your body), so I tried using this powder instead. It is water soluble, so of course it didn't dissolve in my face oil, but I put a few drops of water in the palm of my hand with this vitamin C powder and my face oil and the crystals dissolved just fine. I put the combination on like I normally do, and it felt the same (a slight stinging from the vitamin C). I now will use this on my face and save myself the outrageous price of $35/tiny vial of the other face powder - and save my body from the harmful ingredients it contains!This product is fantastic for inside the body and out!
