Just recently ordered this and LOVE! Green Tea EGCG truly is one of the most fantastic skincare actives out there. Very difficult to find good quality product (90%) and even harder to actually solubilize it! Love that it comes in pre-dissolved solution. I enjoy adding it at 1% (so 11% sol) to my serum formulations containing Niacinamide 5% + NAG 3%. Excellent for oily acne prone skin.
*Only gripe... because the Pre-Dissolved Solution is SO heavy in propanediol (10 parts Propanediol for 1 part E.. ...»
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... ...»
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.. ...»
I ordered the 50 gm after being very pleased with the smaller size. Although it's pricey the quality is outstanding. This is the safest way to add Vit C to your formulations as it's not nearly as fussy as the powder. I've made both serums and creams with this product and have been very pleased with the outcomes! Highly recommend!.. ...»
I am very happy with both the quality and packaging of the Ferulic acid I ordered. It came in foil packets (I ordered two). Will buy from them again as I use the product in my Vitamin C serum to maintain the PH needed... ...»

GABA (gamma-aminobutyric acid) is a neurotransmitter with purported dermatological benefits. Several patents indicated that GABA can be used as a wrinkle relaxer based on its inhibitory effect on muscles. Some patents also claim that GABA can dilate skin peripheral blood vessels, moisturize and prevent aging, suppress parakeratosis and shrink pores, as well as whitening the skin. However there is no scientific data to support these claims. On the other hand, a preliminary research study has shown that GABA can stimulate hyaluronic acid synthesis and protect the fibroblasts from oxidative stress. Another study showed that GABA was able to upregulate beta-defensin-2, which is an anti-microbial peptide, and filaggrin, which plays a role in normal barrier function of the skin. Lastly, GABA might be useful in combating inflammation associated with psoriasis based on preliminary findings that GABA receptors are expressed in white blood cells in psoriatic skin. Overall, the evidence of GABA in supporting skin health is very weak, and consumers are warned for its application.
Unsubstantiated benefits of GABA (Gamma-aminobutyric acid) in skin care:
Capillary health 
Lightening and brightening 
Moisturizing and hydration 
Pore refinement 
Reduce fine lines and wrinkles 
Restore barrier function 
Stimulate HA production 
Wrinkle relaxers

About GABA (Gamma-aminobutyric acid) in DIY Skin Care
Gamma-aminobutyric acid (GABA) is a well-known neurotransmitter. In the mature brain of humans, it exerts inhibitory function on neurons when bind to GABA receptors, through regulating the chloride gradient across the cell membrane. GABA is synthesized by enzymes called glutamate decarboxylase, using glutamate as the substrate. Once synthesized, it is transported in little vesicles to the synapses of the neurons, and its action depends on its metabolism, expression, and activity level. GABA is important for brain development, and its dysfunction has been linked to a myriad of neurological disorders such as autism, Fragile X, Rett syndrome, Down syndrome, schizophrenia, Tourette's syndrome and neurofibromatosis.
GABA has been marketed as a wrinkle relaxer based on the claim that it can inhibit neuronal activity and hence relax muscles, limiting the “expression lines” resulted from muscle hyper-contraction such as in the peri-oral regions. There are several patents that indicate such function when used topically. Other patents that mentioned GABA’s benefits include dilation of skin peripheral blood vessels, moisturizing and age-preventing, suppressing parakeratosis and pore shrinking, and whitening effects. However, there have been no peer-reviewed study published to date (May, 2015) on these effects.
Research on dermatological use of GABA has been sporadic. It has been shown that glutamate decarboxylase exists in human dermal fibroblasts, and GABA can stimulate the synthesis of hyaluronic acid and enhances the survival rate of the fibroblasts when exposed to oxidative stress in vitro. GABA synthesized from fermentation of grape must using bacteria (Lactobacillus plantarum) has been shown to increase the level of beta-defensin-2, hyaluronan synthase, and filaggrin in reconstituted human skin tissue, suggesting that GABA might play a role in anti-microbial function, hydration, and proper barrier function of the skin. GABA receptors are expressed in a number of white blood cell types in psoriatic skin, and GABA has been implicated to be important in relieving inflammation associated with psoriasis. These studies provide new possibilities for the application of GABA, however consumers are encouraged to exercise precautions due to the fact that none of these studies has been replicated and substantiated.
