Growth Factors: The Science Behind Skin Rejuvenation

Posted on04/01/2021

Growth factors play a pivotal role in maintaining firmness and elasticity in your skin. Daily use of skin care products containing growth factors are known to help reduce the appearance of fine lines, wrinkles and improve skin tone and texture.

Found in abundance throughout the body, growth factors are large proteins that float between cells communicating crucial messages relevant to growth, healing, and survival. 


  They’re manufactured by all types of cells. In the skin, this includes those comprising both the outermost epidermal layer and the deeper dermis--so, we’re talking the keratinocytes you can plainly see in the mirror, and the fibroblasts (collagen factories) and melanocytes (pigment-making cells) nestled down below. When these signalling proteins bind to receptors on cell surfaces, they can send commands to replicate, repair, and rejuvenate.


Growth factors are natural substances made by skin cells to maintain healthy skin. They are responsible for supporting the repair of damaged skin, making components that provide firmness and elasticity to the skin while helping to maintain skin's protective functions


Where Do Growth Factors in Skin Care Products Come From?


Advances in biotechnology over the past decade have created multiple sources of growth factors. They can be derived from several different animal and plant. While all cells can produce growth factors, the composition of the growth factor blend they produce is likely to be ideal for the health of cells that produce them.

For example, fat stem cells are likely to produce growth factors that help the functioning of fat cells and bone marrow stem cells are likely to produce growth factors that help with functioning of bone marrow. Similar logic can be applied to growth factors or growth factor-like substances derived from non-human sources. Therefore, to maintain optimal skin health, ideal growth factors would be produced by skin cells, called fibroblasts, whose main function is to produce the components necessary to support the skin.


Don’t understand these at all? The easy way to understand is that you can view growth factor as the icing on the cake if you’re looking to maximize your skin-care regimen.
