Discovery of Growth Factors
Skinmedica was the first company to come out with growth factors in skin care products. SkinMedica uses an ingredient called tissue nutrient solution in their growth factor serums. It is a combination of many types of growth factors.
What are growth factors?
Growth factors (GFs) are special proteins or steroid hormones that are made by various cells like keratinocytes, fibroblasts, platelets, and certain immune cells. GFs are signals used to change gene expression or communicate with other cell structures. Because of this, GFs play a crucial role in how cells move, grow, multiply, and change.
There are many types of GFs. Some of them can revitalize older skin cells like keratinocytes and fibroblasts, making them work better. However, it’s essential to understand that GFs don’t act alone. They work together as a team, where each player has a role. If you remove one player (or type of growth factor), it can change the whole game’s dynamics. That’s why when we study GFs individually, it’s hard to see the full picture of what they can do.
When we talk about growth factors in skin, there are epidermal derived and dermal derived growth factors that have different effects. What they do depends upon which ones are present.
Many skin serums use only one or two types of growth factors. TNS, or human conditioned fibroblast media- is the growth factor ingredient in SkinMedica products. TNS containing products have only dermal-derived GFs. This is not the same as what occurs naturally in the skin where epidermal and dermal derived growth factors work together. However, SkinMedica has new technology knowns as TNS-MR that has a wider range of growth factors which makes the SkinMedica TNS Advanced + Serum the best growth factor serum.
What do growth factors in skin care products do?
Growth factors are used to rejuvenate the skin. They prompt fibroblast skin cells to make important things that the skin needs to look younger such as collagen, elastin, and glycosaminoglycans. Loss of these skin components causes wrinkles, thin skin, and sagging.
What growth factors do in skin:
Affect cells close to where they are produced.
Regulate cell growth, proliferation, and differentiation.
Bind to specific receptors on the surface of their target cells.
Increase the production of collagen, hyaluronic acid, and elastin, which are key components for maintaining skin’s elasticity and hydration.
Speed skin healing
Make skin look smoother and younger
Exfoliate by promoting cell turnover and shedding of the older outer skin layers

Which growth factor is best as an antiaging ingredient?
TGF-β has the most data to support its use for antiaging.
Platelet derived growth factors found in exosomes have also been shown to be beneficial to treat aged skin.

Are Growth Factor Serums Worth The Price?
Growth factor serums are expensive. Are they worth it? It depends upon how well they are formulated, how long they have been in the cream and on the shelf, where they are stored, if they are stored in air conditioning, and what other products they are used with in the skin care routine.
Problems with growth factors in skin serums that decrease effectiveness
Skin products with growth factors are a waste of money if active growth factor do not make it deep into the skin’s dermis where the fibroblasts are.
There are many issues that make it difficult for active growth factors to penetrate into these layers such as:
Unstable in the bottle or jar
Difficulty penetrating into the skin because they are too big (2, 3)
Rapidly broken down by protease enzymes on and in the skin
Damaged by free radicals (5)
Do not make it to the target receptors
Inactivated before they can do anything
Short half life (5)
For these reasons, the way that the growth factor products are formulated, how they are layered with other ingredients, and the step they are used in the skin regimen is very important!
Your skin care routine affects how well growth factors work
The presence of other products in your routine has a huge effect on growth factor serum effectiveness. For example, low pH cleansers lower the skin’s pH which could inactivate growth factors unless a higher pH moisturizer is layered on top.
These issues affect how well growth factors work in your skin routine:
Skin pH
Presence of occlusives
Presence of penetration enhancers
Presence of heparan sulfate
Status of the skin barrier
Are growth factors safe?
There has been a lot of buzz around growth factors (GFs) and their potential benefits, but there is still a lot we don’t know about the safety of cosmeceutical GFs. For instance, we are not entirely sure which GFs or their combinations in beauty products might promote or prevent skin cancer. What we do know is that certain skin cancers have receptors for the Epidermal Growth Factor (EGF), and when EGF is present, the outlook isn’t so great. And there are skin care products that proudly tout the presence of EGF in them! Yikes!
Some studies suggest that factors like EGF, TGF-α, FGF, VEGF, and PDGF might have negative roles in cancer.
Skincare products with GFs taken from fibroblast cells have been available for years. But here’s the catch: we don’t have a clear picture of how safe they are, especially for those with skin cancer. While there haven’t been any reported cases of skin cancer directly linked to growth factors in skin care products, a lawsuit in 2014 raised concerns about undisclosed risks. This lawsuit was eventually dismissed in 2018. The lingering worry? That these GFs might encourage unwanted skin cells to grow. So, if you choose to use GFs, watch your skin for any unusual growths and see a dermatologist immediately if you see anything suspicious.
