Dr. Hannah Sivak, supplier of Active Proteins for the Cosmetic Industry

After a long career in basic science, comprising plant biochemistry, protein structure, and modification, I retired from academia and joined the ”real world” in Arizona. Since then, and with the help of my colleagues who stayed at the ivory tower of academia, I have been applying decades of scientific research to cosmetics.

I had the opportunity to learn firsthand how the skin care industry works from the inside. In the cosmetic industry, science is used mainly as a marketing tool, not a practical guide for formulations. My son Jonatan, with a background in physics and logistics, pushed me to start a business and do things my way by putting science first. Eventually, this became a very complex company, which produced and sold hundreds of different ingredients and cosmetic products.

Now, I decided to simplify and go back to basics: proteins, my area of expertise. I supply these proteins and advise my clients on how best to use them. These are the best active proteins available to the cosmetic industry, and I supply them at a cost that allows for them to be used at effective concentration, not for "label value".

If you are interested in growth factors, antioxidants, and skin healing, please feel free to contact me for ingredients and scientific support. Find me at info at hannahsivak dot com to acquire these proteins: growth factors, antioxidant enzymes, antibacterial and healing proteins. I only sell to the cosmetic industry and liability insurance is a pre-condition for the sale.
