Really loving this product. I make the best Centella toner and most concentrated ever. 2 g of centella extract dissolved in 10g of alcohol(you have to stir a lot) plus 88 grams of water and you get a very concentrated toner. Creams, toners, ampoules... all have only 0,1% of triterpenes, this toner i make have 1,4%. I am loving it, will see the results. .. ...»

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... ...»

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..... ...»

Grape Seed Proanthocyanidins
Grape seed extract is a mixture of complex molecules, mostly proanthocyanidins. These molecules are very strong antioxidants, even surpassing vitamins C and E, and also show anti-inflammatory activity. Due to these properties, grape seed extract is a promising drug in combating cancer. It is capable of protecting the skin from melanoma and other cancer types, prevents already formed tumors from spreading, and can even reverse the damage in cancer-forming cells. It also reduces the cosmetical damage of UV exposure, such as increased pigmentation, thus lightening the skin. Grape seed extract is also useful in regulating sebum secretion. Finally, wound healing is strongly supported by applying this extract, as it helps tissue regeneration and provides a powerful defense against resistant bacteria.
NOTE: To assist you with solubility issues, we now also sell Grape Seed Proanthocyanidins as a liquid standardized pre-dissolved solution. Just add the liquid to your cream and mix well.

About Grape Seed Proanthocyanidins in DIY Skin Care
Grape seed extract is produced by purifying the most beneficial components from grape seeds. Among these components, most is known about proanthocyanidins – these molecules are produced in plants by combining several smaller molecules called flavonoids. Flavonoids are known for their antioxidant capabilities, and in proanthocyanidins this effect is even stronger, exceeding vitamins C and E [1]. This activity makes them useful in protecting all systems of the body – they reduce UV damage in skin, ethanol damage on liver, ageing damage in brain and other negative symptoms associated with oxidation. Together with several other compounds found in grapes, proanthocyanidins are very promising anticancer drugs, as they were shown to reduce the growth of diverse cancer types [2].
In skincare, the most important function of grape seed extract is protecting against sun damage. Solar UV is the primary cause of non-melanoma skin cancer, and it has been shown that applying grape seed extract before exposure significantly reduces the damage to cells [3]. It is proven that proanthocyanidins are responsible for this protective action, as they enhance DNA repair in the damaged area [4]. Similar results, leading to decreased cell death, were also found in another study [5]. In fact, grape seed extract can even be used to treat skin cancer, as it is able to restore the genes in tumor cells to their healthy state [6]. Similarly, melanoma cells can become less invasive, and thus less dangerous, after treatment with this extract [7]. Application of grape seed extract on healthy volunteers’ skin, irradiated with UV, also reduced the cell damage that may lead to cancer [8]. Furthermore, this extract inhibits the inflammatory processes that typically start after UV exposure. This also leads to reduced cancer risk [1].
The antioxidative abilities of flavonoids are useful not only in response to UV. Using a cream with these and other antioxidants for 21 days, significant reduction in wrinkles was observed, as well as protection from UV – this indicates potential anti-ageing effects of this extract [9]. New research also indicates that a cream containing grape seed extracts is able to protect against infrared A radiation – no other formulation has been proven to achieve this [10]. These effects suggest that grape seed extract would be a valuable addition to any sunscreen, since no adverse effects of this extract have been observed [9].
Grape seed extract also has other cosmetic benefits. In volunteers applying 2 % extract-containing cream, skin elasticity was significantly improved, together with decreased sebum secretion and melanin content (pigmentation) [11]. Using a complex formulation with extracts from grapes and other sources, numerous skin benefits were observed, among them increased hydration, collagen content, and sebum reduction [12]. However, the large proanthocyanidin molecules are absorbed rather slowly through skin. To enhance this process, it is advised to use this extract in high water content formulations, or apply together with hydrating agents [13].
Finally, wound healing process is also aided by applying this extract. Not only do the wounds heal faster, but the regenerated tissue shows better structure and larger collagen amounts [14]. Again, 2 % was the concentration of extract that gave the best results in these experiments [15]. Additionally, grape seed extract is known to have strong antibacterial and antiviral properties. It is even able to destroy antibiotic-resistant bacteria, proving its usefulness in wound care [16].
