What are growth factors?

Growth factors act like messengers, transmitting information between cells and regulating cellular functions such as cell division and the production of extracellular matrix (e.g., collagen). As cells age, the skin's ability to recover from damage weakens, and collagen production also decreases. Some say that by controlling cellular functions, skin aging can be reversed. Is this truly the case?

Research shows that topical application of growth factors can alleviate the signs of photoaging. Growth factors can increase the division of fibroblasts and keratinocytes, and enhance collagen growth. Where do the growth factors in products come from? They can be extracted and refined from epidermal cells, human or animal placentas, genetically modified bacteria, plants, etc. Some growth factors can also be produced directly through chemical processes.

There are many types of growth factors, and the most common ones used on the skin include fibroblast growth factor, transforming growth factor, platelet-derived growth factor, vascular endothelial growth factor, placental growth factor, and insulin-like growth factor. The detailed functions will not be described further here, as different growth factors control different functions, but to repair the skin, one cannot rely on a single type of growth factor.

Theoretically, growth factors extracted from human tissue have better effects because the chemical substances are more compatible. In fact, they can indeed improve skin aging problems (neo-angiogenesis).

Beauty products containing growth factors are diverse, and their product quality, type of growth factors, concentration, etc., greatly affect clinical results.
