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... ...»
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.. ...»
The best, most potent and most stable form of Vitamin C.
Makes quite a difference to the appearance of mature, photo-damaged skin - don't expect results over night but with consistent use your skin will look more even and radiant!.. ...»
This ingredient has done more for my skin than anything else I've ever used.
I put it into a spray facial toner and use it morning and night. I noticed the effects immediately, they were that dramatic.
I will use this forever, no question... ...»
I've been using Bulkactives green tea EGCG for four years. No complaints, it blends nicely my DIY anti-aging cream. I can feel a bit of toning and definitely notice the anti-inflammatory effects on my skin. Two observations that keep the rating 4 stars instead of 5: (1) A package of green tea contains significantly less weight/volume than the package of grape seed extract that I order from bulkactives. The two are combined in equal amounts in the anti-aging cream, so I find myself running o.. ...»

Buy Ascorbyl Glucoside (Ascorbic Acid 2- Glucoside) For Skin Care
Ascorbyl glucoside (AA-2G) is a vitamin derivative, produced biologically by the reaction between glucose and vitamin C. This addition confers greater stability, compared to relatively unstable pure ascorbic acid, thus allowing for wide usage in pharmacy and cosmetics. AA-2G retains the antioxidant properties of the unmodified vitamin, therefore it is used to prevent radiation damage, cell senescence and skin darkening. It also promotes collagen synthesis, as well as cell proliferation – these mechanisms help improve the appearance of the skin and reduce wrinkles. Furthermore, since AA-2G does not release ascorbic acid instantly, all the listed positive effects are sustained longer and the possibility of adverse effects is reduced, compared to using pure ascorbic acid. All these qualities make AA-2G the most attractive vitamin C derivative for cosmetic use.
Key benefits of Ascorbyl glucoside (AA-2G) in skin care:
Antioxidant  
Lightening and brightening 
Treat hyperpigmentation 
Sun damage repair  
Sun dammage protection  
Stimulate collagen production  
Reduce fine lines and wrinkles

About Ascorbyl Glucoside (Ascorbic Acid 2- Glucoside) in DIY Skin Care
Ascorbyl glucoside (scientific name ascorbic acid 2-O-alpha-glucoside, AA-2G) is a stable derivative of ascorbic acid, commonly known as vitamin C. Commercially, AA-2G is produced directly in biological systems, simply by reacting glucose with an ascorbic acid molecule . It is also formed naturally in animals, during simultaneous digestion of vitamin C and carbohydrates . While ascorbic acid has numerous cosmetical and pharmaceutical benefits, it is relatively unstable, and degrades even at neutral pH and body temperature . Addition of glucose serves to protect this molecule. Upon entering the body, ascorbyl glucoside is easily digested back into ascorbic acid and glucose, resulting in stable vitamin C delivery without any toxic effects . It has also been shown that this compound is metabolized fully, and the amount of vitamin C gained from AA-2G or pure ascorbic acid is equivalent . In fact, this modification allows for more controlled release of the vitamin, while pure ascorbic acid can lead to cell toxicity if absorbed suddenly and in large quantities , . As a tradeoff, absorption of modified vitamins through skin is less effective, but AA-2G in this respect surpasses other molecules .
Vitamin C is widely known for its antioxidant properties. It functions in neutralizing free radicals, such as reactive oxygen species, that can form due to radiation or other factors. This activity is important in preventing cancer, ageing-related diseases and radiotherapy damage . Ascorbyl glucoside shares similar qualities. As an antioxidant, AA-2G was found to perform similarly or even better than ascorbic acid, for example, in protecting skin cells from ultraviolet radiation , . It was also observed to protect cells against damage from high-energy radiation, similar to that used in radiotherapy . Recent research confirmed that AA-2G protects skin cells not only from oxidative stress (free radicals), but also from cellular senescence . Ascorbyl glucoside even has a positive effect on immunity, as it promotes antibody synthesis in lymphocytes . Again, ascorbic acid has similar benefits, but also causes adverse side effects that are not observed when using AA-2G .
The importance of vitamin C in collagen synthesis is well known since the times of scurvy – besides activating synthesis in various ways, it functions as a necessary cofactor for the relevant enzymes. This has led to its use in anti-wrinkle cosmeceuticals. For example, a cream containing 3 % ascorbic acid has been shown to significantly reduce facial wrinkles and ageing-related damage . Activity of AA-2G is similar, as it promotes collagen accumulation, cell proliferation and formation of tissue structure . Furthermore, this molecule has a longer-lasting effect, compared to pure vitamin C. One study found that ascorbic acid stimulation of collagen synthesis ceased after 3 days, while a similar amount of ascorbyl glucoside maintained active collagen synthesis for 5 days . Under different conditions, similar difference was observed, with ascorbyl glucoside remaining active for at least 8 days and ascorbic acid being depleted after 5 days .
Another application of AA-2G in cosmetics is control of skin pigmentation. Due to its antioxidant properties, this compound reduces the rate of melanin synthesis, thus preventing skin darkening after UV exposure. This effect, together with reduced inflammation, was demonstrated by applying a cream containing 2 % ascorbic acid or related molecules, and AA-2G was found to be even more effective than unmodified vitamin C . It was also found that the whitening activity of AA-2G increases greatly when combined together with resveratrol .

After preparing an Ascorbyl Glucoside stock solution, neutralize it tp pH 5.5 by using Triethanolamineand then add it to the formulation.
If the formulation needs heating, cool down the formulations to 40-50°C and then add the neutralized Ascorbyl Glucoside solution. Please avoid heating at high temperatures (above 40°C) for prolonged periods.
Adding buffers, chelating agents and antioxidants, and shielding from strong light are also useful in preventing Ascorbyl Glucoside from decomposition during formulation.
The stability of Ascorbyl Glucosideis influenced by pH. Please avoid leaving it under prolonged conditions of strong acidity or alkalinity (pH 2-4 and 9-12).
