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.. ...»

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..... ...»

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.. ...»

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.. ...»

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.
  • 11% solution gives 1% Proanthocyanidins content in final product.
  • 32% solution gives 3% Proanthocyanidins content in final product.
  • 53% solution gives 5% Proanthocyanidins content in final product.

Key benefits of Pine bark Proanthocyanidins in skin care:
  • Sun damage protection [3], [6], [11]
  • Antioxidant [1], [2]
  • Increase skin elasticity [9]
  • Moisturizing and hydration [9]
  • Lightening & brightening [11]
  • Wound healing support [12], [13]
  • Capillary health [11]
  • Anti-inflammatory [3]–[5]
  • Water soluble!

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].
