Growth factors are natural proteins that are found in abundance in young healthy skins that are critical for rejuvenation. These proteins carry the signal relevant for growth, healing, and the survival of cells in the body. When activate, they send commands such a to grow and divide, produce collagen and elastin and regulate and increase blood flow needed for repair. However, as we age, these aren’t as active in our bodies as it should be hence, such active ingredients can be found in our skin care products such as serum, gels and creams either bioengineered or from stem cells that can take cue from the surrounding tissues and speed up cell regeneration and rejuvenation process.
