I' m not sure about this: "11% solution gives 1% EGCG content in final product." What is the weight of final product? .. ...»

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... ...»

I am following the moisturizing cream + Zinc dispersion recipe and I am extremely satisfied. I do allow for a little time for it to absorb in & then I dab off anything that I feel looks a little white - but that's because I initially use a fairly thick coating on myself. I use a bit of foundation at times on top and there are no issues as far as weird colors or texture issues. I am so grateful for this entire website as a one-stop-shop for such effective skin care products, and now we can.. ...»

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... ...»

Glucosamine (N-Acetyl Glucosamine)

N-acetyl glucosamine is a compound with a wealth of uses for improving skin condition. It is a known precursor to hyaluronic acid, a major component of skin structure. Hyaluronic acid is essential for hydration and n-acetyl glucosamine has been shown to increase moisture. N-acetyl glucosamine helps heal wounds, increase collagen, and reduce acne. It reduces hyperpigmentation, especially when combined with niacinamide, a member of the vitamin B3 family. It has anti-oxidant and anti-inflammatory properties which allow it to help heal and prevent sun damage. Overall, this compound can help prevent premature aging and reduce signs of aging, such as wrinkles, especially when combined with niacinamide.

Key benefits of Glucosamine in skin care:

  • Stimulate HA production [2] [3] [4] [5] [6] [7] [8] [9] 10]
  • Moisturizing and hydration [2] [5] [9] [11]
  • Treat hyperpigmentation [2] [4] [9]
  • Wound healing support [2] [11]
  • Stimulate collagen production [11]
  • Scar care [2]
  • Anti-acne [2] [6]
  • Anti-inflammatory [2] [3]
  • Anti-oxidant [2] [7]
  • Sun damage repair [1] [7]
  • Sun damage protection [7]
  • Increase skin elasticity [5] [11]
  • Reduce fine lines and wrinkles [2] [10]
  • Matrix metalloproteinases [MMP] inhibitors [7]

About N-acetyl Glucosamine in DIY Skin Care

N-acetyl glucosamine is an amino sugar present in all human tissues [7]. It is a stable form of glucosamine that penetrates skin easily [4]. It is a good cosmetic, as high concentrations of n-acetyl glucosamine do not cause irritation [9]. N-acetyl glucosamine is a precursor to hyaluronic acid, also known as hyaluronan [2]. Hyaluronic acid is a large component of connective tissue and has roles in both skin structure and hydration. The molecule is known to hold water in the skin, increasing moisture [11]. Hyaluronic acid is present in the epidermis and stratum corneum, two different layers of the skin [9]. Cosmetic formulations including n-acetyl glucosamine have many advantages.
 
Topical n-acetyl glucosamine decreases flakiness, increases skin hydration, and has exfoliating properties [9]. It has been studied as an alternative to alpha hydroxy acids, compounds commonly found in commercial anti-aging treatments that can irritate skin and increase UV damage. An increase in skin elasticity, thickness, and plumping was seen after 8% n-acetyl glucosamine application [5].
 
One of n-acetyl glucosamine’s most studied topical uses is for reducing hyperpigmentation [4]. In a clinical study 2% NAG applied topically significantly reduced hyperpigmentation. This is because n-acetyl glucosamine inhibits tyrosinase activation. Tyrosinase is an enzyme involved in melanin synthesis [4]. Hyperpigmentated age spots are localized accumulations of melanin. Thus, by keeping tyrosinase from becoming activated, the amount of melanin produced is less, which decreases the appearance of age spots. When combined with 4% niacinamide, a member of the vitamin B3 family, the pigmentation reducing effect was greater [4, 9]. This shows n-acetyl glucosamine and niacinamide should ideally be used together to produce better results.
 
An in vitro [outside the body] study shows there is an age-related decrease in glucosamine incorporation into hyaluronic acid. This contributes to wrinkle formation [2]. Studies show that applying n-acetyl glucosamine topically increases hyaluronic acid amounts in the skin [2]. This effect is greater when combined with niacinamide, which is a cofactor in hyaluronic acid synthesis [10]. A clinical study using topical 2% n-acetyl glucosamine showed a reduced appearance of wrinkles [2]. Women using a 2% n-acetyl glucosamine and 4% niacinamide cream showed a larger improvement in fine lines and wrinkles, especially under the eyes [10]. Glucosamine compounds are also known to have anti-inflammatory characteristics [3]. Inflammation can accelerate skin aging, so anti-inflammatory products are useful for preventing this change.
 
Topical n-acetyl glucosamine also reduces acne [2, 6]. In a clinical study, 8% n-acetyl glucosamine was less drying and irritating than benzoyl peroxide, commonly applied to treat acne [6]. It also helped eliminate acne and was able to reduce acne faster than benzoyl peroxide [6].
 
N-acetyl glucosamine increases activity of antioxidant enzymes, thus reducing the amount of harmful free radicals produced after UV exposure. Hyaluronic acid is also known to scavenge free radicals [2]. N-acetyl glucosamine also inhibits matrix metalloproteinases [MMP] that degrade collagen after UV damage [7]. It increases the viability of skin cells exposed to UV radiation. It has also shown to be useful for the prevention of photoaging [premature skin aging due to excessive sun exposure]. Also, hyaluronic acid levels decrease after UV radiation exposure and in sunburned skin [1]. Thus, replenishing hyaluronic acid through application of n-acetyl glucosamine may help heal sun damage.
 
N-acetyl glucosamine also increases collagen production by fibroblasts [collagen producing cells] [11]. Collagen is important for the structural support of skin. It aids in wound healing and improving elasticity. This study shows the fibroblasts were able to regenerate faster after injury in the presence of n-acetyl glucosamine [11]. Additionally, maintaining an abundance of hyaluronic acid in wounds during the healing process produces better results with less scar formation [2].
