Growth Factors in Skincare and How Do They Work
Growth factors are special proteins in your skin that tell cells to grow, repair, and communicate with each other. In skincare products, they help renew your skin from the inside, making it look firmer, smoother, and younger.[1][2]
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 natural proteins, kickstarting the processes your skin used to do on its own.[2][3]
One popular type is Epidermal Growth Factor, or EGF. It works on the top layer of skin, called the epidermis. EGF binds to receptors on skin cells like keratinocytes, encouraging them to multiply, move, and mature. This speeds up surface repair, smooths texture, evens tone, and boosts radiance. Plant-based EGF from ingredients like those in boosters is gentle and great for mature skin.[1][2]
Another key one is Fibroblast Growth Factor, or FGF. It targets deeper in the dermis, where fibroblasts live. These cells make collagen, elastin, and hyaluronic acid, which give skin its bounce and hydration. FGF ramps up production of these building blocks, improving density, elasticity, and resilience against sun damage.[2][3]
Platelet-Derived Growth Factor, or PDGF, also activates fibroblasts to build more collagen and elastin. It helps plump skin, reduce fine lines, refine texture, minimize pores, and fade spots or acne marks.[1][3]
In products like serums, boosters, or creams, growth factors often pair with things like vitamin C or plant extracts for better results. They penetrate to signal cells directly, unlike surface moisturizers. Over time, skin looks luminous, feels smoother, and holds up better to aging.[1][2][3]
You might find them in ampoules, serums, or anti-aging treatments. They suit most skin types and work well with other ingredients, helping repair barriers and fight free radicals too.[1][4]
