Wow, definetely helping with fine lines around eyes, and my acne scars are MUCH less visible! I couldn't realise why. But then I though it must be it, since I am not using any other supplements or special creams. I was using it on and off for couple weeks and didn't see much difference, and was thinking why everyone was so happy about it. But only after 2 weeks everyday use I've seen huge improvement. Please feel free to click "yes" if you find my review helpful for you. Best wishes

A Must Have!

Posted by HawaiianViking on Oct 25, 2012

I have tried many, many different products for my dry, sensitive skin — collagen of different kinds, DMAE, hyaluronic acid — not to mention (probably) dozens of lotions, oils and salves, and none have been as effective as Natural Factors, BioSil, ch-OSA Advanced Collagen Generator. Within about two weeks of treatment with this product, my skin was much smoother and more even, and felt less itchy and patchy. I'm taking it together with Biotin and Pycnogenol, and I think I've found a winning combination in those three supplements. As for the taste of BioSil: I take it in a cup of water, and I don't love it but neither do I find it particularly awful. Perhaps it's because I've taken a lot of really nasty supplements in the past, but this one really isn't so terrible.

Natural Factors,BioSil,ch-OSA Advanced Collagen Generator is an excellent supplement. I have been using it for over 3 years and it keeps my sensitive skin healthy looking and definitely has eased the lines and wrinkles that come with middle age. I initially started taking it for my hair that had gone from thick, to losing a lot, and weak/thin nails. It has improved my hair thinkness and growth almost to the condition it was, when I was in my teens to 30's. It has also improved the stregnth and growth of my thinner/weaker nails as well. I take it with juice 2 times a day and really am happy with the results. I am sure it benefits many other things inside my body too. I highly recommend it for anyone who needs help with weakening/thinning hair, weak/thin/infected nails, and to improve skin health along with decreasing lines and wrinkles. It took a few months to really see the benefits, however, it was really worth it, after struggling with hair, skin, and nail problems for a couple of years, as I got into my 40's. Now, I really see the benefits after 3+ years, and I am really greatful and thankful for this supplemental product and its avaiability to me. Again, I highly recommend this supplemental product. , from Hawaii.

When I was first diagnosed with Hypothyroidism, I had already lost a lot of hair. I used to have handfuls of long hair, but it got so thin that I could see through it halfway to my crown on the top of my head. I was prescribed medicine for my condition which stopped the hair loss but didn't bring it back. BioSil has helped a lot! My hair is not back to the lush fullness of my youth, but it has gotten noticably thicker and stronger.

Bucks the trend...

If you're anything like me, you've probably spent several hundred dollars (if not more) on supplements over the years, only to discover that three-quarters of them appear to make little or no discernable, tangible, difference to your health, despite the claims of the manufacturers. I am very pleased to say that, for me, Biosil is a very notable exception to this trend. This stuff works. I'll say it again: THIS STUFF WORKS! I have close-shaven hair (about 1/8" long)and because of this, it is readily apparent to me when my hair has changed because any difference in stiffness makes it much harder to run my hand over. Whenever I stop using Biosil for a few weeks and then return to it, the difference in strength of my hair is quite startling. I highly recommend this product if you suffer from silicon deficiency (most people do), and I also suggest you look into Kervran's book 'Biological Transmutations', which is hard-going but discusses the concept of transmutation of minerals. While this concept has yet to garner wide-spread acceptance, there is good sense behind it and it points to the possiblity that silicon can be used by the body for many purposes other than those directly pertaining to silicon in its basic form. That Biosil makes silicon so abundantly-absorbable for the body, only adds to its potential.
