RESURRECTIONbeauty L-Ascorbic Acid Powder (Vitamin C), 6 oz. Jar. For Use in Serums and Cosmetic Formulations.

منتج رائع ع البشرة يجعلها نضرة

Good amount of product for the price. Dissolves well and works great in my serums.

Like every Ascorbic Acid the powder does not dissolve well in water. I make my own hyaluronic acid with ferulic acid and Vitamin C serum. In order for it to dissolve the powder must be ultra fine. So I took the whole content and ground it in a coffee grinder wore a mask and put it on parchment or wax paper and then put it back in the container. I use half a tablespoon for a 60ml product finished size with half a tablespoon of distilled water in a hot water bath just for a short while and with a mixer it's dissolves completely.

Delivered fast , in good package. As described

For the price this can't be beat. I make my own vitamin C serum on a weekly basis and this bad boy is going to last me forever!! It is not a fine powder!! I know others have said that they have issues with it not dissolving fully in water because of the larger crystal size and I've encountered this as well. I have a nutribullet with the milling blade. So... I milled this to a finer powder (not super super fine though) and still had some issue with it dissolving fully. If you use hot or warm water, this stuff dissolves instantly and won't recrystallize. So just nuke your water for 30 seconds in the microwave. I think if I were to repurchase I wouldn't bother with milling it and just use warm or hot water to dissolve the crystals. I am particular to L Ascorbic acid over other forms of vitamin C since I've seen the best results with post acne hyperpigmentation. I have used L-Ascorbic acid by simply mixing the powder into my sunscreen, lotion, body lotion, or just added it to water. If you have ever used Philosophy's Turbo Booster C Powder it's just 99.9% L-Ascorbic acid powder with a ginormous markup ($39/ 0.25 oz). Why waste your money? For making my weekly Vitamin C serum I like to use rosewater- don't know if it actually helps with anything, but I love the smell. I use 2 teaspoons of vitamin C powder and 4 teaspoons of microwaved rose water then I test this with a pH strip!!. This makes an approximate 20% solution. The pH is usually around 2 pH. This is too acidic and you'll likely wind up with irritated red/flaky skin. I adjust the pH to around 3-3.5 pH using baking soda. I add teeny tiny increments and test using pH strips till it gets to the 3-3.5 pH range. I haven't had any skin irritation issues with this adjustment and the results are great. I find using a vitamin C serum prevents hyperpigmentation and minimizes my acne. Whenever the solution starts to tint yellow or orange it's time to throw it away. It means it has oxidized and will cause adverse skin reactions if used- so don't. What I make lasts me about a week with daily use. Definitely worth a purchase!

Good product, I'll buy again
