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... ...»

This product is amazing! I'm new to diy moisturizing cream and I've done quite a bit of research. However, I found info. at BulkActives that I have not seen anywhere else, especially with the hyaluronic acid. This product is of high quality, my friend is a chemist and he ran some tests, very high quality. It has done wonders for my skin, not only in the way it looks more healthy but it just feels so smooth and hydrated. I'm still experimenting with some recipes so I will return. Your service is .. ...»

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.. ...»

I have been buying from bulkactives for some time and have never been disappointed. My most recent purchases have been the hyaluronic acid and the dispenser bottle. the bottle is great. The inner container rises with use, ensuring that you use most of the product. Much better than having residue sit at bottom of bottle to be wasted. I've used only one batch of hyaloronic acid formula, so too early to report. I mix it with ascorbic L and ferulic acid, according to recipe on this site. So f.. ...»

Another great find on bulkactives. Mixed with de mineralized water, you have the basis to add to any serum, mix with your moisturiser, to simply use on it's own. Love it... ...»

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.. ...»

Hyaluronic Acid 50 kDa (Low Molecular Weight sodium hyaluronate)

Hyaluronic acid [HA] is an important component of the extracellular matrix.  Known to have a role in stimulating dermal fibroblast migration and proliferation as well as for tissue hydration, topical HA has been used in cosmetic applications for decades.  Its skin-benefitting properties along with its ability to bind and retain huge amounts of water makes HA ideal for use in anti-wrinkle, anti-aging, and moisturizing creams.  HA can exist across a wide range of molecular weights, with the cellular and physiological effects directly depending on the molecular weight of HA present.  Therefore, the selection of HA species for use in such creams is of critical importance.  High molecular weight HA does not penetrate the epithelium.  Very low molecular weight HA, which does penetrate the skin efficiently, can induce a pro-inflammatory response.  Recent data indicates that solutions of low molecular weight HA [50 kDa] are best suited for topical use in skin care products as it can penetrate into the skin well but does not cause inflammation.  Note: Hyaluronic Acid 50 kDa does not create a thick gel, for this reason we have started selling Sclerotium Gum, the combination of the two ingredients will create an excellent, safe, and efficient product. Warning: Customers in countries with a dry climate may find that hyaluronic acid has a drying effect, instead of moisturizing. It is theorized that this is due to the HA drawing moisturize away from the skin.

Key benefits of Hyaluronic Acid 50 kDa (Low Molecular Weight sodium hyaluronate) in skin care:

  • Moisturizing and hydration [2] [3] [4]
  • Reduce fine lines and wrinkles [2] [4] [6]
  • Increase skin elasticity [2] [4] [6]
  • Wound healing support [3] [7]

About  Low Molecular Weight Hyaluronic Acid (LMW sodium hyaluronate Powder) in DIY Skin Care

The appearance of the outer layer of the skin, the epidermis, is supported primarily by the dermis and the extracellular matrix it secretes.  This matrix, sandwiched between the epidermis and the dermis, is an organized and highly structured environment.  While collagen and fibrin primarily make up the support system of this structure, hyaluronic acid [HA] is the filler and cushion which provides the mechanical integrity for that structure.  Composed of long chains of non-sulfated glycosaminoglycans, HA contributes to maintenance of the skin through dermal fibroblast cell proliferation and migration [1, 2]. 

Arguably the most important property of HA is its ability to bind water and regulate the hydration of tissues.  HA, whose molecular weight can reach into the millions of daltons, can hold hundreds of times its weight of water.  Under certain conditions, degradation of HA occurs and results in the appearance of sagging or wrinkled skin.  This may happen as a result of infection, wound, or simply the natural aging process [3].  The high water-holding capacity and the contribution to maintenance of the dermal layer of skin makes HA extremely attractive for use in moisturizers and anti-aging creams as well as for wound healing support.

Although commonly used in commercial anti-wrinkle, anti-aging, and moisturizing formulas, high molecular weight HA can actually not efficiently penetrate the barrier of the epidermis [4].  Thus, these creams are not as effective as generally perceived.  Further, once in the skin, the physiological effects of HA depend on the molecular size of the HA species present. 

Very low molecular weight HA species [approximately 20 kDa or below], actually have pro-inflammatory effects and cause or increase inflammation.  These HA species can bind to receptors on macrophages in the dermis, Toll-like receptor 2 and 4, and initiate an immune response [5, 6].  Although potentially useful for wound care, low molecular weight HA confers a negative effect in terms of skin aesthetics.  In contrast, high molecular weight HA does not stimulate macrophages to initiate an inflammatory response.  This indicates that selection of HA species to be used in cosmetic applications must be done carefully.  The HA used must sufficiently penetrate the skin to elicit benefits but must do so without stimulating an immune response.

Recently, studies on HA suggest that formulations containing low molecular weight HA of approximately 50 kDa are ideal.  50 kDa HA efficiently penetrates into the skin as is evidenced by a skin diffusion assay whereas the 300, 800, and 1,500 species penetrated significantly poorer.  A trial in which human participants were treated for 8 weeks with a HA topical solution containing 50, 130, or 300 kDa demonstrated that the 50 kDa solution most significantly decreased skin roughness whereas the 300 kDa treatment had no measurable effect.  Further, the appearance of wrinkles in the 50 kDa treatment group was significantly decreased [7]. 

It has been shown that the 800 kDa high molecular weight HA species commonly used in cosmetic formulations can activate approximately 40 genes in keratinocytes which are involved in skin cell regulation and formation of cell-cell tight junctions.  In a reconstructed epidermis model in which the skin was treated with high molecular weight HA [800 kDa] or low molecular weight HA [50 kDa], the 50 kDa HA stimulated approximately 120 genes including keratinocyte cell regulation and tight junction proteins.  Of note, no pro-inflammatory genes were activated.  The additional benefits of the 50 kDa at the molecular level are believed to be directly related to the increased penetration of this species [6, 7].

Note: Hyaluronic Acid 50 kDa does not create a thick gel, for this reason we have started selling Sclerotium Gum, the combination of the two ingredients will create an excellent, safe, and efficient product.
 

Hyaluronic acid in dry climates

"there is a controversy whether concentrated HA formulas should be used as a moisturizer in dry climate. When air humidity is very low, HA may preferentially pull water from the skin rather than from the air, thus producing the opposite effect." [ Dr. G. Todorov. Hyaluronic acid for skin hydration and possibly a lot more.1999-2015. SmartSkinCare.com]

To properly use a hyaluronic acid serum, it needs to be applied onto damp skin and then "sealed" in with a layer of a good moisturizer on top. If applying the hyaluronic acid in this manner still makes your skin feel a bit dry or taut, the hyaluronic acid is probably pulling moisture out of your skin instead of pulling moisture from the air and into your skin.

Note that the combination of Niacinamide and Glucosamine has been proven to actually increase Hyaluronic acid synthesis in the skin, thereby moisturizing from the inside, rather than putting moisture on top of the skin.
