100% Pure L-Ascorbic Acid (Cosmetic Vitamin C Powder for Face) to Make Your Own Premium Beauty Serum, Skincare Mask Treatment, Hyaluronic Serums with Vit C & DIY Facial Skin Care Products 6 OZ

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

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!

I’ve been using the 100% Pure L-Ascorbic Acid (Vitamin C) Powder for a few weeks now, and it’s been a game-changer in my skincare routine. Mixing a small amount with my favorite serum creates a fresh, potent vitamin C treatment that leaves my skin looking brighter and more even-toned. I’ve noticed a significant improvement in the overall texture and radiance of my complexion. One thing to note is that the powder can be a bit grainy and doesn’t always dissolve completely, which might be a concern for those with sensitive skin. However, by adjusting the concentration and ensuring it’s well-mixed, I’ve been able to minimize any irritation. The value for the price is excellent, especially considering the quality and effectiveness of the product. Overall, this vitamin C powder has become a staple in my skincare arsenal, offering customizable and powerful antioxidant support.

It is a pretty good product BUT it is not fine and (powdery) enough to stay on the skin or even dissolve well in the fluid. It is very gritty and grainy on my skin so I’m afraid my skin is not truly getting the full benefits because the product is just sitting on top of my skin. You do get a lot of it compared to what The ORDINARY gives but I will be going back to The ORDINARY product.

I add it to my distilled water and glycerin serum. Takes a little while to completely dissolve. It is clear, if it starts to color then it has oxidized and needs to be dumped and a fresh batch made. Don't mix up more than you will use within 1-2 weeks. I've been using this serum morning and night for 5 months. My skin looks smoother and less pigmented. Make sure to keep it in the dark once mixed to slow the oxidation process. I use a dark glass bottle which I store in a drawer and have had it still good at 3 weeks when I finished it off. Haven't used any other brand yet, but will update when I have. Still have a lot left in this container. I am up to a 15% serum solution now, but started at a 5% to get my skin adjusted. I have given myself a chemical burn with citric acid not properly diluted and it is possible to do the same with this. Do your research and know your skin. If you are having trouble getting it to dissolve, then you are doing something wrong. The higher the solution strength, the longer it will take to dissolve. I didn't check to see how long mine took because I wasn't going to be using it until the next day. Was completely dissolved by morning. I mix directly in my 2 oz. spray bottle and shake well. I use a small funnel and L-ascorbic acid first, then distilled water. I shake these first before adding my glycerin. I always shake mine before using. Don't know if it's necessary, force of habit with any liquids.

I have to do a solid for Resurrection Beauty. I'm new to making my own serums and still learning a great deal. Resurrection Beauty's vitamin C is my third brand to purchase. After my purchase was well on its way to me, I then decided to read the reviews of the product. They gave me concern that my product would not dissolve enough. This prompted an experiment as soon as my vitamin C powder arrived. I took a lidded jar and put some vitamin C powder in it, added some filtered water, and let it sit for a while, probably fifteen or more minutes. It dissolved just fine. I took the few teaspoons of water with the visibly dissolved product in it, and ran every drop over my hands a little at a time, feeling it as well. Perhaps for dissolving in your hand for immediate use, this vitamin C powder may not work as quickly as some. For dissolving in water for homemade serums, it seems to work as well as both of the other, more expensive brands I've purchased.

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

Good product, I'll buy again

I am making my own vitamin C facial cream as this type of vitamin C is stable and very effective (I add to to existing cream). It is great! I will never go back to prepared cosmetic vitamin C cream. One note. You can’t use it with retinol products at the same time as they cancel each other out. Vitamin C in the morning and retinol at night!
