What Are Growth Factors in Skincare
Growth factors are special proteins in your skin that tell cells to grow, repair, and communicate with each other. In skincare products, they come from plants or labs to help your skin look younger and healthier by speeding up natural renewal processes.
Your skin naturally makes growth factors, but as you age, it produces fewer of them. This leads to slower cell turnover, less collagen and elastin, and signs like wrinkles, dullness, and bigger pores. Skincare with growth factors steps in to mimic these proteins and kickstart repair.
One popular type is Epidermal Growth Factor, or EGF. It works on the top layer of skin, called the epidermis. EGF binds to cell receptors and boosts cell growth, movement, and new skin formation. This smooths texture, evens tone, and makes skin firmer and brighter. Plant-based EGF is common in creams and serums because it acts like the human version without needing animal sources.
Another key one is Fibroblast Growth Factor, or FGF. It targets deeper skin layers, the dermis, where fibroblasts live. These cells make collagen, elastin, and hyaluronic acid, which keep skin plump and bouncy. FGF helps rebuild this structure, reducing wrinkles, improving density, and fixing sun damage.
Platelet-Derived Growth Factor, or PDGF, also activates fibroblasts for more collagen and elastin. It is used in serums to plump skin, fade fine lines, and refine texture. All these factors protect against damage from free radicals and help with issues like acne scars or spots.
In products, growth factors often pair with vitamins or plant extracts for better results. You might find them in boosters, ampoules, or creams for mature skin. They stimulate collagen production, shrink pores, add glow, and restore elasticity over time with regular use.
