The hair strengthening serum contains actives known to help promote hair growth, both in men and women. It has been designed to help with poor micro-circulation, follicle atrophy caused by dihydrotestosterone, and follicle aging. Full nutrition is provided to compensate for loss of nutrients brought about by poor blood irrigation.

KGF: this protein (19,000 molecular weight) , is also known as FGF-7 and heparin-binding growth factor-7 (HBGF-7). KGF is a member of the fibroblast growth factor family and was found to stimulate hair growth. Cells that respond to KGF do so because they have receptors on the cell membrane that recognize the factor (which has been produced by cells that may be near or far from the target cell). The binding of the growth factor to the receptor initiates a cascade of molecular events that will eventually lead, among other effects, to cell division.. We make our own growth factor using biotechnology. Please ask about special wholesale prices. Please note that our growth factors are sold for use in cosmetics only.

Sea kelp bioferment: complete nutrient supply, moisturizer. The substrate for fermentation is a sea macroalgae rich in caragenaan, algin, minerals and many active chemicals. Fermentation makes the cell contents of this algae readily available to your skin, moisturizing it and providing the nutrients required to synthesize new components.

Carnitine: antiage, L-Carnitine and derivatives like acetyl carnitine, carry activated fatty acids through the mostly impermeable inner mitochondrial membrane, allowing the respiration of fatty acids. The activated fatty acid (Acyl-CoA) cannot pass through the membrane but there is a special translocator for Acyl-carnitine. Once carnitine releases the fatty acid it carries (a process involving a tranferase), carnitine can go out again and take up another activated fatty acid. L-carnitine is a derivative of the amino acid lysine, and it is named after the material it was first isolated from, meat (carnus in Latin), in 1905. It was first believed to be a vitamin, and called vitamin BT, but humans can synthesize L-carnitine, although under certain conditions and depending on the diet the demand for L-carnitine may exceed an individual's capacity to synthesize it, making it a "conditionally essential nutrient".

Grape seed proanthocyanidins: antioxidant, promotes hair growth. Derived from the seeds of both red and white grapes, grape (Vitis vinifera) seed extract , containing 95% proanthocyanidins, is one of nature's most powerful antioxidants and a major free radical scavenger. These flavonoids protect capillary walls and inhibit the enzymes that break down collagen (collagenase), hyaluronic acid (hyaluronidase) and elastin (elastase). Proanthocyanidins also help promote tissue elasticity, help heal injuries, reduce swelling and edema (anti-inflammatory), restore collagen and improve peripheral circulation. Proanthocyanidins also prevent bruising, strengthen weak blood vessels and reduce histamine production.

Niacinamide: anti-age, anti-itch. Niacinamide is a vitamin, but even when following a normal healthy diet, topical application of niacinamide will result in increased synthesis of collagen, keratin, involucrin and flaggrin. Topical application of niacinamide will decrease pruritus and inflammation, decrease oiliness, alleviate atopic dermatitis, and decrease UV-induced skin cancers. These are just a few of the beneficial effects of topical application of niacinamide to the skin, and it would be suspicious that there are so many were it not for the crucial role of this chemical in human metabolism.

Soy isoflavones: antiage. Isoflavones are polyphenolic compounds capable of exerting estrogen-like effects, i.e. they will bind (weakly) to the estrogen receptors on the surface of your skin cells. Cells in human males also have receptors for estrogen. The amounts of soy isoflavones will be enough to help with hair growth without leading to unwanted side effects.

Saw palmetto: Saw palmetto (Serenoa repens) sterols have been shown to inhibit 5-alpha-reductase activity, the enzyme responsible for conversion of testosterone to dihydrotestosterone and to inhibit binding of dihydrotestosterone to the cytosolic androgen receptor. Chrysin: promotes hair growth.

Apply Brow and Lash Serum to the brow line and the lash line (on the eyelids) twice per day.

Note: Rinse with water if it spills in the eyes.

  I love this serum. I has thickened & darkened my sparse brows after 6 wks & will continue to use nightly for further results. After I finish the eyelash serum I currently use, I'll buy another tube of KGF serum for eyelash growth. Incredible price! A+
• Author: Wanda
  Wow! after only 3 weeks I can see a difference in my brows and lashes.
  
  This stuff is great, I bought it for my son's girlfriend also and she is seeing results to.
  
  Thanks for awesome products.

  I just turned 50, and have been using the brow & lash serum for a month. I wish I took "before" pictures, but I was too lazy, and I didn't want to be reminded of them anyway!
  
  My lashes weren't terrible, it's just that mascara didn't really make much difference. Then all the Latisse ads made me wonder & surf the web for information.
  
  I passed on Latisse (price, side effects) and tried Double Lash - nada. Plus it irritated. Now I just use it to set my brows. No actives in that one at all.
  
  But in a month of SkinActives' Brow & lash serum - yes, definitely a difference. I also use the Chrysin on my lids, mostly for the dark circles, and I understand that may help lashes too.
  
  I can't tell if my lashes are thicker yet, but they are definitely longer. They sometimes hit my reading glasses (lenses), and I notice them in my eyeline in general (never did before.)
  
  My lashes look much fuller with the tinest bit of mascara - I look a like I've added a few individual lashes. And I notice they definitely stick out when I glance at my profile in the mirror.
  
  So there's at least one bit of month-long feedback from a 50 year old!

  I have been using the Brow and Lash Serum for just about a month and there is a definite thickening and darkening of my eyebrows and some growth of my upper lashes. I'm so delighted that at the age of 65, I might be getting the "Brooke Shields" brows I used to have back .
  
  I'll be trying more of your products.
  
  Thank you, Hannah!

  Great stuff! Not only do I have eye brows not, but the wrinkles on my eyelids are gone. Wow!

  At 57 I felt I had no hope to repair the overplucked brow that I damaged years ago. Well, I have used this serum for about 5 months. Even tho I sometimes forget to apply this at nite.. I have regained about 50 fine hairs - on the outside-end, where I overdid my 'shaping" years ago. Yes, it was a slow-ish process, but even as a person with fine hair, I got some real benefit. - A few hairs at a time! Now I have enough new growth to add a little pencil color or that creme-color. Even some fine hair makes a big difference in appearance. Absolutely. The improvement is real, the price is truly fair! Thanks SAS!

  Wonderful product! I have a small scar from an accident crossing my left brow - It has always been a tiny bald patch right there. This patch is gone now! It took a couple of months, I applied the serum twice daily to my brows. But now I got an even brow line again. Nice for me, as I am not a fan of full on make up, using brow liners etc.. I just can't be bothered and prefer my natural brows and their color.
• Author: Maria
  This stuff really works!! I had completely lost the outter half of my left brow...age, I guess. Yesterday, after about 8 weeks of use, I actually had to do some plucking at the outside edge of my brow!!! Not only do I have full brows again, my lashes are longer as well. Some mornings I forget that I have brows again and start to pencil in...and then quickly realize it's not necessary.

  I cannot believe how much my brows have grown with this, I need to get them waxed for the first time in years!
• Author: Tricia
  I used this product for a couple of months before putting it on the shelf...I saw no change or improvement in either my lashes or brows. I have a slight bare spot in one of my brows, so I would have known for certain if it was causing growth, but saw none. I also saw no growth or change in thickness in my lashes. Sigh. Oh well.

  I bought the brow and lash serum because I read in the forum it helps reverse crepey skin around the eyes, not for my lashes - my lashes, while blonde, were there.......or so I thought. After using this for 4 weeks? NOW I've got some gorgeous long, thick lashes....and they're getting darker too! The crepey eye skin has improved......but I can't say if it's this serum, or all the other wonderful SAS products I am using!
• Author: Jeanine
  I have been using this for several weeks and I can officially say I'm seeing an improvement now. My eye lashes have always been rather skimpy and they are definitely thicker and longer. I noticed it when I put my mascara on and thought maybe I'd bought a different and better mascara, but no.....same old stuff. My brows appear to also be a bit thicker as well. I apply this to the skin under my eye brows as well as to the skin at the base of my lashes twice a day.

  I've had success with this despite using it incorrectly. Brows are thicker & I'm suspecting less grey, hard to tell when I cant see the grey, but I have purchased a nasty backlit, magnifying mirror & still cant find them. I think the eyelash success was when I used lots & actually got plenty on the eyeliner area not just the lashes I've read all the reviews on the top brands but they are priced from $50-$150au so I'm sticking to this one.

  I developed allergies over the past 2 years (my doctor says it is common when relocating to California), since then my eyelashes have been falling out (about 1-7 lashes a day). I decided to try this to thicken my almost nonexistent lashes and it is amazing. I have been using this product for a little over a month and my eyelashes are not shedding anymore and they are longer than they have ever been!! I will continue to use this, thanks for a great product!

  I'm a religious user of many SkinActives products and love to mix my own things, but this product just did not work for me. I'm in my 40s and was hoping to get thicker brows and a lusher lashline, but after using for 1 month 2x a day, there was no discernible difference. I don't know enough about this to try a stronger concentration - or maybe some individuals respond to it and others just do not.

  I have very thin brows after overplucking in my teens, I'm now 47 & they have never grown back. I had not noticed any regrowth after using this serum for 2-3 months twice a day, but forever hopeful, I continued to use it, although mostly only once a day now, & after 5 months total I began to see some new growth so I have continued to use it daily & the new growth is increasing, it's a long time to wait but totally worth it & I can now finally get a decent shape to my brows without having to pencil in large areas, & they now look much more natural. I can honestly say I love this stuff . Thanks for a great product at a great price.

  I used this product religiously for a few months and didn't see any additional growth or thickening. I did notice that it my pores seemed a little more clogged around my eyelashes but I'm not sure if this was the cause of it. I had really hoped this would thicken my eyelashes but it just didn't work for me. =(
• Author: Janet Price
  I did not see any results on eyelashes or eyebrows. I have seen great results with Rapidlash.
• Author: Taylor Roberts
  My lashes are hitting my glasses now! Its been 3-4 weeks and I am starting to notice a change. I don't always remember to put it on twice a day so it may not take as long for some people. I have always had wimpy lashes so its very easy for me to tell that its working. :)
• Author: Nancy Welker
  After a "salon disaster" three years ago my always thick brows were waxed so thin it looked like they belonged to someone else. I have tried lots of other company products, but I always come to the brow & lash serum here at Skinactives. It's excellent. It works. I am pretty much done with the rest at this point.

  After several weeks I began to notice a difference in the length of my eyelashes. Not spectacular, but it is apparent. I have used for it for several months now. I would advise changing to a container similar to a nail polish bottle. It is very difficult to access in its current container.
