Great l-ascorbic powder

Posted by iHerb Customer on Aug 24, 2011 | Verified Purchase

I bought the ascorbic acid powder to make my own vitamin c serum. I only mix it with purified water and make it fresh every time I use it because it is very unstable in water. The powder resolves instantly in water and so far the serum has done great on my skin. It fades my acne scars, evens out my tone and even give me a nice glow. I do not have to use any moisturizer after I apply the serum at night which is a super plus for my very acne-prone skin because I haven't found any moisturizer or lotion that won't break me out so far. I checked a few online store and my local whole food store and the price on iHerb is the best. I will definitely recommend to a friend and repurchase myself. Thank you iHerb for providing such a wonderful product!

Thanks for your feedback!

I'll be a returning customer.

Recently, I reviewed the item which I bought: the NutriBiotic, Ascorbic Acid, as I was looking for other things to buy. I can say, that this ascorbic acid has been living up to my expectations, in every way. I've been using it for five weeks now, 1 gr in a glass of water, sometimes with a squirt of lemon juice, 3-4 times a day. For twenty years, I was a consultant, prescribing vitamins and minerals, and I know a lot af different vitamin-C products by now.

Thanks for your feedback!

Additive for Face Cream

Posted by iHerb Customer on Apr 07, 2011 | Verified Purchase

Good anti-aging face creams have this pure form of Vitamin C and cost 100's of dollars. The formula for the cream is simple, 1 of the ingredients calling for Ascorbic Acid. The crystals must be completely dissolved. They dont completely dissolve no matter what. It does work because I can feel the "sting" when applied and can see the difference in my skin. Please dont make your own cream until you have done much research. It can be damaging if not done correctly.

Thanks for your feedback!

For my DIY serum ^^

Posted by Pinkymobo on Jul 08, 2013 | Verified Purchase

I bought the ascorbic acid powder to make my own vitamin c serum. I mix it with hydrosol but purified water is also ok. I add also vegetable glycerine cos some people it helps to bring the Vit C into the cell. It takes some stirring to dissolve the powder into water but everything else is ok. I like what it done to my skin~~~brighter, some of the light dark spot seems fading.....but I do notice a few breakout, may be my skin needs to adapt to it (I've just start using it for 3 weeks) I also put it on my hand & neck & my hand looks more supple instantly!!! (I'm just over 30) it's a wonderful product! ............PS. It's sooooo sour to drink with water!!

Thanks for your feedback!

Great vitamin C and at a great price! Very pure and dissolves well in water. Vitamin C is great when taken with other supplements to compliment their effectiveness. ======================================================================================================= If you like my review, please click ‘Yes’ below the review.

VITAMIN C - A TRUE UBIQUINOL

Posted by iHerb Customer on Mar 20, 2015 | Verified Purchase

The Vitamin C was excellent. After reading the book by Dr. Thomas Levy, "Curing the Incurable", I have incorporated Vitamin C into my daily diet. Whenever I feel bad or just a little worse then normal, I immediately take about 10 grams of Vitamin C and usually feel better in a short period. If you have ever wondered at the ability of the body to keep it's shape and function, Vitamin C is a factor in about 10,000 chemical reactions in the body, and is a precursor of collagen, which is the connective tissue which holds the entire body together and makes us so durable. Vitamin C does a body good, and that is why I take 10 grams per dsy. p.s. After taking the powder form of ascorbic acid, I rinse out my mouth, as ascorbic acid will etch enamel slightly if left in the mouth. Even better, I use some baking soda in the rinse solution, since baking soda will neutralize the acid in Vitamin C. Do not swallow the baking soda right after the C.

Thanks for your feedback!
