Growth factors are complex and powerful actives that play a critical role in maintaining firmness and elasticity in your skin as well as wound repair and healing. They communicate with your cells to create more collagen and elastin. When used daily as part of your skin care regimen, they are known to help reduce the appearance of fine lines, wrinkles and improve overall skin tone and texture.
They can benefit anyone showing early signs of aging but the most visible differences will be seen in those with greater photo-damage and mature skin.
But anti-aging is just one thing. They are also vital for wound repair and healing.
It is a complex, multicellular process. This process involves the highly coordinated efforts of several cell types including keratinocytes, fibroblasts, endothelial cells, macrophages, and platelets. The migration, infiltration, proliferation, and differentiation of these cells will culminate in an inflammatory response, the formation of new tissue and ultimately wound closure.
This complex process is executed and regulated by an equally complex signalling network (communication) involving numerous growth factors, cytokines and chemokines. Of particular importance is the epidermal growth factor (EGf) family, keratinocyte growth factor (KGf), melanocyte growth factor (MeGF), transforming growth factor beta (TGf-beta) family, fibroblast growth factor (FGf) family as well as many more.
In short, when you wound the skin, you trigger an incredibly intelligent, intricate, highly well organised series of events which go into overdrive to repair what has just been damaged. It’s for this reason that before you receive a treatment such as Skin Needling, it’s imperative that your skin is well prepared. If you’re lacking in some of these growth factors, the healing process can be severely disrupted and the results less than desirable.
