Im 45 years old; average looking skin for my age. Applied a small pea sized amount of Sea Kelp Bioferment to my face full strength in the am after washing my face of previous night makeup.; let face "dry". Then aplied my foundation as always. Noticed my thick, heavy foundation applied more easily and smooth. Keep in mind this is DAY TWO of me using this. TWO women at work ( separate departments) commented how wonderful my face looked! One specifically came up to me and asked what I was.. ...»
The Pre-dissolved solution is excellent. Ferulic Acid is an amazing skincare ingredient (potent antioxidant, protects other sensitive antioxidants from light degradation, UV protection) but is absolutely ineffective if it isn't solubilized correctly.
Makes adding to any Serum Base or w/o emulsion easy. Love using it (at 6%; so active 0.5%) with the Resveratrol Fluid (10%; active 1%) and Green Tea Extr for potent nighttime brightening treatment... ...»
Carla, Many medications can be and are applied topically by prescription. With that in mind, realize that this particular ingredient is wonderful but understand that this is indeed one of those that may create sensitivity with those already using topical hormones or just use sparingly and see how you respond. Sorry for the very late response..... ...»
Many thanks for the Silicone DM. This product is lovely quality; it is light, silky, and leaves no residue at all.
I use it in the base recipe for a mouldable polymer that I then use to make a simulated 'Amber' for bead making.
At the end of this process I have a silky, translucent polymer plus the most gorgeous hands in the studio !
My thanks again, Helen.. ...»
I wished i could order this in a smaller amount of 50 gr. Can i get informed when it is available ?
A. It will not be sold in smaller amounts. The review rating is meant to be for the product, not the size in which it is sold :-(.. ...»
I am following the moisturizing cream + Zinc dispersion recipe and I am extremely satisfied. I do allow for a little time for it to absorb in & then I dab off anything that I feel looks a little white - but that's because I initially use a fairly thick coating on myself. I use a bit of foundation at times on top and there are no issues as far as weird colors or texture issues. I am so grateful for this entire website as a one-stop-shop for such effective skin care products, and now we can.. ...»

Buy Ascorbic Acid -L (ultra fine powder) For Skin Care
L-ascorbic acid (vitamin C) is an essential nutrient which has many cosmetic benefits. It is a remarkable antioxidant and can scavenge reactive oxygen species and other free radicals, protecting the skin from oxidative stress. It can stimulate collagen synthesis by promoting cross-linking and stabilizing collagen molecules, upregulating collagen genes, increasing the transcription of the tissue inhibitor of matrix metalloproteinase 1, and inducing fibroblast proliferation. It reduces pigmentation by suppressing tyrosinase, which is important for melanin production. It is an anti-inflammatory agent and can be used to treat inflammatory skin disease such as erythema. Together, L-ascorbic acid provides powerful anti-aging properties and has been shown to reduce wrinkles, improve elasticity, and protect against sun damage. Stability and absorption of L-ascorbic acid is a concern. While the anhydrous L-ascorbic acid might be the most stable form, adding vitamin E not only helps stabilizing L-ascorbic acid, but the two have synergistic effects on anti-aging. Used in: philosopy's turbo booster c powder and SkinCeuticals.
Key benefts of L-ascorbic acid in skin care:
Antioxidant     
Increase skin elasticity 
Lightening and brightening     
Matrix metalloproteinases (MMP) inhibitors 
Moisturizing and hydration 
Reduce fine lines and wrinkles     
About L Ascorbic Acid / Vitamin C in DIY Skin Care
L-ascorbic acid (AA), the active form of vitamin C, is a remarkable anti-aging substance due to its anti-oxidative, collagen-producing, and pigment-reducing effects. Humans have to get AA from food sources, however since its active transport from our digestive system is low, it is hard to achieve optimal skin level of AA from food alone. AA level decreases with sunlight and pollution quite dramatically, and topical supplementation of AA can provide an ideal solution especially considering the fact that keratinocytes can actively take up AA and maintain its level efficiently.
AA protects against oxidative stress by scavenging reactive oxygen species and other free radicals that are a result of normal daily function, UV radiation, and/or pollutants. This was evident in human skin both in vitro and in vivo. Interestingly, AA does not function alone as an antioxidant. Rather, AA is able to recycle oxidized a-tocopherol (which is produced constantly on the cell membrane) and hence regenerate vitamin E, augmenting the skin’s anti-oxidative capacity. AA and vitamin E work synergistically, as shown both in human skin cells and a randomized, double-blind trial.
AA is an essential cofactor for two enzymes involved in collagen synthesis, lysyl hydroxylase (for cross-linking collagen molecules) and prolyl hydroxylase (for stabilizing collagen). AA increases collagen synthesis in vitro, ex vivo, in a controlled clinical trial, double-blind controlled trials, as well as a randomized double-blind controlled trial. It has been shown that the stimulatory effect of AA on collagen synthesis is at the DNA level, not just post-translational. In addition, AA application increased the mRNA of tissue inhibitor of the collagen-degrading matrix metalloproteinase 1. Furthermore, AA stimulates fibroblast proliferation, further contributing to wrinkle reduction, as seen in a controlled trial, and randomized double-blind controlled trials.
In addition to anti-oxidative function, AA combats pigmentation also by suppressing tyrosinase, an enzyme that is crucial for melanin formation. AA inhibits pigmentation in vitro, in vivo, in a controlled trial, a randomized double-blind trial, and a randomized double-blind controlled trial, while providing sun damage protection and repair.
AA is anti-inflammatory and has been used to treat erythema in a randomized controlled study. AA was also effective at treating striae alba (stretch marks) and can possibly provide would healing support. Interestingly, AA has also been shown to increase certain sphingolipids in vitro, such as ceramides, and might be helpful in maintaining the barrier function of the skin.
AA is highly unstable under the exposure of water, air, and light (because it is such an excellent antioxidant). There are many strategies for increasing the stability and absorption of AA, one of which is altering its chemical structure. However, for any of the AA derivatives to be effective, they need to be able to release or be converted back to AA in the skin. Adding vitamin A, vitamin E and/or cinnamic acids derivatives (such as p-coumaric acid, ferulic acid, caffeic acid, and sinapinic acid) help stabilize AA, and it has been suggested that the anhydrous form of AA is the most stable.

Key ingredients of Vitamin C, Vitamin E, and Ferulic Acid serum:
15% L-ascorbic acid: Neutralizes free radicals and promotes collagen synthesis.
0.5% ferulic acid: This plant-based antioxidant neutralizes free radicals, inhibits UV-induced melanogenesis, and has anti-inflammatory properties.
Assay: 99.8% CAS#: 50-81-7 INCI: L-Ascorbic Acid Description: powder Mesh size: 100% through 100, 95% though 200 (US standard sieve) - Ultra-fine powder.
Our 100% pure L-Ascorbic Acid is an ultra- fine powder. It feels like ICING SUGAR. It does not require grinding and will EASILY dissolve in water up to 25% , it also disperses very well in a silicone base. Solubility: water pH: 2.2 - 2.5 (at 5% in water) Suggested percentage: 10% to 15% (20% if you can handle it) Stability: L-Ascorbic Acid is very unstable. As soon as you put it in water, it will start oxidizing. It is best used fresh every day. It can be made substantially more stable if your formula contains a large percentage of ethanol. Ferulic Acid will also help stabilize it.
Shelf Life: The manufacturer's stated "best use" date is two years from date of manufacture, if the container is unopened and stored away from heat, light and air. We repackage this product in foil bags. Over time, constant opening and closing of the bag will eventually allow the l-ascorbic acid to adsorb the moisture in the air and it will begin to oxidize. This will be noticeable as it takes on a yellow color in solution.
Storage: Cool, dry place. Do not freeze. Keep away from light and moisture! Country of origin: Japan
