This is a fantastic product. Highly moisturizing and smooths out lines and wrinkles. It works quickly and is evening out skin tone as well. I think its a must have product and I certainly will be purchasing it again.. ...»
This lovely, simple, and affordable product has become something I don't want to be without. I am 47, with very sensitive and reactive dry skin. This cream doesn't feel particularly moisturizing and leaves something of a 'dry' finish on the skin after application, but it's had SUCH a positive impact on my face. The redness and papules from my rosacea and seb derm have reduced by a good 90%. It's been a magical barrier restorer and I panicked when it was temporarily out of stock. I would recomme.. ...»

Tried this on my week-old rash from flea bites. Got an almost instant relief and rash healed in 2 days. Tried it on my daughter who has eczema for a very long time.

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.. ...»

Pine Bark (95% Proanthocyanidins)

Pine bark extract is a mixture of organic molecules with various health and cosmetical benefits. The proanthocyanidins found in this mixture have strong antioxidant properties. They are also known to reduce inflammation and redness (erythema) resulting from it. Combined, these effects make pine bark extract a potent defense against UV radiation, and it can even prevent various types of skin cancer. Furthermore, toxic effects of metal ions can be alleviated by applying this extract. In postmenopausal women, this extract has been proven to reduce wrinkles and improve skin hydration. Additionally, the molecules found in pine bark maintain good blood vessel health – the extract can alleviate hypertension and help capillaries recover after injuries, making it useful in wound care.

NOTE: To assist you with solubility issues, we now also sell Pine Bark Proanthocyanidins as a standardized pre-dissolved solution. Just add the liquid to your cream and mix well.

About Pine Bark (95% Proanthocyanidins) in DIY Skin Care

Pine Bark (95% Proanthocyanidins) skin carePine bark extract is a complex mixture of organic molecules, of which proanthocyanidins and phenolic acids are most interesting. These ingredients are frequently used both in nutritional supplements and dermal applications, mostly due to their strong antioxidative capabilities [1]. While individual components are still difficult to research, the benefits of whole extract have been observed in various systems of the body, from UV protection of the skin and melanoma inhibition, to alleviating smoking damage and premenstrual symptoms [2].

It is known that pine bark can effectively reduce inflammation of the skin cells. Inflammation of the skin is often studied by exposing the skin to high UV doses, thus causing a reaction called sunburn. It was shown that pine bark applications reduce this reaction markedly [3]. It can also be used as a preventive measure, for example, cells pretreated with pine bark extract showed 70 % less signs of inflammation than untreated cells [4]. However, the anti-inflammatory effect has not been tracked down to a single component, so likely the extract has numerous ingredients that work together and cannot be replicated in a laboratory yet [5]. Surprisingly, in cases when stronger immune response is actually needed, pine bark extract can adapt to this function as well and promote immune reactions. In mice, treated with UV and certain drugs suppressing the immune system, dermal application of pine bark-containing cream reduced the suppression 4 times, thus strengthening the protective functions of the skin [3].

Concerning UV exposure, several other benefits of pine bark extract have been observed. Erythema (redness), induced by these waves, is effectively reduced by the extract [6]. Similar effect was proven in mice, using creams with 0.05-0.2 % pine bark extract. The extract also delayed the appearance of UV-induced tumors, and the 0.2 % cream fully prevented some mice from developing cancer [3]. Pine bark extract is even able to protect the skin cells from more potent chemical carcinogens [7]. Erythema, inflammation and tissue damage can also be caused by skin contact with ions of heavy metals, such as chromium. Experiments with animal skin show that the antioxidants contained in pine bark extract provide a useful defense against these toxins [8].

Postmenopausal women often experience skin dryness, and pine bark extract is particularly useful in treating this condition. It was found that this extract can significantly improve hydration and elasticity of such dry skin. It is achieved by increasing the synthesis of collagen and hyaluronic acid, so this extract is likely to bring similar benefits for any skin with ageing symptoms [9].
Pine bark extract also promotes health of the vascular system. It is able to relax blood vessel walls and in this way reduce blood pressure in animals with hypertension [10]. The antioxidants found in the extract also protect the capillaries, thus it is suggested as a preventive measure against various cardiovascular diseases. Additionally, the extract helps to regulate capillary growth after UV exposure [11]. Blood vessel growth is also important in repairing injuries. This process can also be enhanced by applying a cream with 2 % pine extract – it helps to reduce inflammation, causes faster healing, and even helps reduce pain in burn wounds [12], [13].
