Really loving this product.

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.. ...»

Phytosterols are a family of plant-produced molecules with diverse health benefits. In cosmetics, the ability to stimulate collagen production is most interesting. Together with antioxidant activity and down-regulation of collagen degrading enzymes, these abilities help repair damage in photoaged skin. Phytosterols also have anti-inflammatory properties, which are useful in UV protection, dermatitis treatment, and even cancer prevention. They are widely used in burn wound care – phytosterols were found to improve healing, improve scar appearance and possess analgesic properties, reducing the need of opiate drugs. Antimicrobial activity of phytosterols is also important in skin care, as it can be utilized in both wound care and general fight against infections, such as Candida. Finally, phytosterols regulate transport of cholesterol and thus sebum production – this may present a good treatment option for acne and other sebum-related conditions.

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

About Phytosterol in Skin Care

Phytosterols or plant sterols is a common name for several plant-produced molecules. These molecules cannot be produced in human body, and usually are obtained from oil, nuts and general vegetarian diet. The most abundant plant sterols are campesterol, stigmasterol and beta-sitosterol, with the latter being most important biologically [1]. Other sterols, however, are also continuously investigated, and new applications are being discovered every year.

Beta-sitosterol is most known for its use in wound care. Its anti-inflammatory activity was described long ago, and it is also an antipyretic (reduces fever) of similar strength to aspirine [2]. These properties led to the development of a burn ointment using beta-sitosterol as main active ingredient. It is used to accelerate healing, reduce scarring, and prevent bacterial growth [3], [4]. Clinical studies found that this treatment also helps restore the barrier function of the skin, measured by reduced water loss. Interestingly, this effect was found to be associated with better scar appearance, demonstrating a relation between clinical and cosmetical functions [5]. Improved scar appearance can be already observed after 1 month of treatment, which is relatively fast for scar-treating cosmeceuticals [4]. Furthermore, this ointment has an analgesic effect, with patients requiring much less opiate painkillers while using this mixture [3].

The antibacterial effect of plant sterols is useful in both wound care and general hygiene. While investigating an extract from Alpinia conchigera, researchers found that the main components were phytosterols – stigmasterol and beta-sitosterol [6]. This extract had a strong effect against various pathogenic microbes, including fungi, such as Candida albicans, and even generally resistant bacteria, such as Staphylococcus aureus MRSA strains. Other plant sterol extracts, such as one produced from Aloe vera, also are effective against Candida and other pathogens [7].
Phytosterols also have health benefits in other areas. They reduce the levels of LDL cholesterol, commonly known as “bad cholesterol” [1]. This is relevant not only to the cardiovascular system, as cholesterol accumulation in the skin causes seborrhea, acne, rosacea and other skin diseases. Dermal application of plant sterols can be used to reduce cholesterol transport into skin cells, and thus prevent the cholesterol-related disorders [8].

In the recent years, new collagen-restoring effects of phytosterols have been discovered. Skin cells, treated with phytosterols found in yam plant (diosgenin, stigmasterol and beta-sitosterol), had reduced levels of collagen-degrading enzymes, resulting in significantly enhanced collagen secretion [9]. Spinasterol, another phytosterol, can both increase the synthesis of collagen and decrease the synthesis of degrading enzymes [10]. Fucosterol also has these effects, and additionally promotes antioxidant enzyme synthesis. These benefits were confirmed using skin cells treated with UV (photoaged skin), proving that phytosterols are beneficial for solar protection as well [10], [11]. Dermal applications of spinasterol also reduce edema, indicating anti-inflammatory properties [12]. Furthermore, atopic dermatitis, an inflammatory disease, can be treated with applications of beta-sitosterol [13]. In fact, by reducing inflammation, beta-sitosterol and other phytosterols even reduce the likelihood of cancer development [14].
