Also known as Basic Fibroblast Growth Factor. It has collagen and elastin-boosting effects and can result in firmer, more elastic skin. It has been tested for scar healing, but its use in skincare products is still a bit controversial.

Overview
SH-Polypeptide-1 belongs to the class of human growth factors; this one in particular is a basic fibroblast growth factor which, along with its cousin acidic fibroblast growth factor (SH-Polypeptide 11), tell fibroblasts to produce more structural proteins such as collagen and elastin, making the skin more firm, elastic, and plump.
They also tell the fibroblasts to proliferate (i.e., divide to create more skin cells). This effect is called mitogenic.
The research articles mostly focus on bFGF as a wound healing agent and ingredient for the treatment of badly healed scars. bFGF was tested as an injectable treatment for wrinkles with very good results. When it comes to application as a cream or serum, it must be carefully formulated into liposomes or other delivery systems in order to help it pass through the skin barrier.
The application of growth factors to the skin is a controversial topic, but so far there are no proven negative side effects.
