Sh-Oligopeptide-2 is also called Insulin-like growth factor 1 and it belongs to the same group of ingredients (Growth Factors) as its better-known sister, Epidermal Growth Factor or Sh-Oligopeptide-1. This guy consists of 70 amino acids and, similar to EGF, it is also claimed to stimulate cell proliferation and wound healing. There is also a study that indicates EGF and IGF1 work in synergy to promote keratinocyte (skin cell) proliferation.
The topic of Growth Factors in skincare is complex and controversial. If you are new to it, read our shiny explanation on EGF to get a (hopefully) balanced impression about the pros and cons.
Show me some proof
