Are growth factors like TNS Recovery Complex safe to use?

I know there have been concerns (at least in theory) about abnormal cell growth from topically applied human growth factors. You recommend TNS Recovery Complex and I would love to be reassured that there is little danger from using it since I\'d love to try it.

I think you’ll feel comforted by knowing how they are made.  Since our own cells make these factors, they are completely natural.  To make a long story short, a certified young cell line is grown in petri dishes in the lab.  The cells line the bottom of the dish and a thin layer of liquid food called media  (like a soup) covers them.  As the cells grow, they secrete their own growth factors into the media. The media is harvested, purified and concentrated and put into a serum.  I hope this helps!  Dr. I

One of the best investments in your skin is your daily skincare. Why? Because you can prevent many problems with blotchy skin color, lack of glow, texture, some types of acne, and fine lines with good skincare products. You can also correct some of these problems with effective skincare products. Great skincare is often more expensive because quality ingredients are expensive. Some companies spend on research/development which benefits all of us and adds to the cost. Are they worth it? In general - yes! I have handpicked some of what I consider to be the best skin care products, and offer them for sale on SkinTour's shop. This is based on my team and I's testing and research at our clinic. Many of the products are in my own regimen. What could be better than using skin care products a dermatologist uses?!
