The Science Behind Skin Rejuvenation and the Role Growth Factors Play
Your skin is an amazing organ, capable of withstanding some tough conditions each and every day. Just consider how much your skin does for you, standing up to changing weather, pollutants, the sun, and the ever-present aging process. Through all this, your skin works to maintain, repair, and rejuvenate itself as best it can.
But sometimes it needs a helping hand.
That’s where growth factors come in.
Growth factors are substances naturally created by your skin cells, and they play a role in keeping your skin firm while maintaining elasticity. Growth factors help reduce fine lines, wrinkles, and improve skin tone, which is why they’ve become such a popular component within skin care products.
Let’s take a closer look at some of the most common and popular growth factors, how they work, and how you can incorporate them into your skin care routine.
What Are Growth Factors? How do They Work?
As mentioned earlier, growth factors are naturally occurring substances created by your cells. They’re signalling proteins, which bind to receptors on cell surfaces. They send messages telling your body to replicate, repair and rejuvenate.
Put simply, growth factors tell your skin cells to get to work, either growing and dividing or making more collagen and elastin. The growth factors used by your skin are generated both in the outer epidermal layers and the deeper dermis. They include keratinocytes, fibroblasts, and melanocytes.
The growth factors in your skin care products are usually derived from lab-synthesized human cells, which in turn are sourced from stem cells.
As discussed in past blogs and articles, young, youthful skin typically has no problem producing collagen and elastin, and can quickly repair and rejuvenate thanks to an abundance of growth factors. The problem is that, as you age, your skin starts to produce these growth factors in smaller and smaller quantities.
Why Growth Factors are Used in Skincare Products
As our skin ages, it loses elasticity, firmness, moisture, and the cells of the skin begin to become damaged. These cells cannot replace themselves as fast as the rate at which they’re damaged, which contributes to the aging process.
That’s where growth factors come into play. These handy proteins help your skin and cells get back to work effectively, stimulating the production of anti-aging substances and processes at a cellular level. Because they bind so well with human cells, these proteins are an obvious and popular choice for skin care products.
Anti-aging skin care products usually feature a variety of growth factors, depending on the product’s intended use:
- Epidermal Growth Factor (EGF): This is a popular choice for topical skin care, as it helps increase the production of hyaluronic acid in your skin. Hyaluronic acid helps keep your skin plump and hydrated, reducing the signs of aging while alleviating fine lines and wrinkles.
- Insulin-Like Growth Factor (IGF-1): This growth factor actively stimulates the fibroblasts within your skin. Fibroblasts are found in the deeper dermis and are responsible for the production of collagen and elastin in your skin cells.
- Vascular Endothelial Growth Factor (VEGF): As the name suggests, this growth factor stimulates the formation of new blood vessels, which can help bring more oxygen and nutrients to the skin.
Fibroblast Growth Factor (FGF): This factor stimulates the fibroblasts to create more fibroblasts in your skin. It’s a great way to stimulate regeneration and skin rejuvenation!
Incorporating Growth Factors into Your Skin Care Regimen
When it comes to your unique anti-aging skin care regimen, it’s important to make sure that you are taking the time to find the best products for your needs. If you’re ever at a loss for where to start or feel like you need a helping hand, please don’t hesitate to reach out to me! We can discuss your unique needs as part of a consultation or regular appointment.
Skin rejuvenation starts with good habits, including incorporating amazing growth factor-using products into your skincare routine. While they cannot completely stall aging, they can help slow them down and help you look and feel your best. At my clinic, we carry two medical skin care lines, SkinMedica and AnteAGE MD, both designed to help your skin’s natural growth factors keep working to their full potential.
If you’re dealing with breakouts, dry skin, sensitive skin, damaged skin, or frustrating skin texture, it might be time for you to start looking at growth factors as a way to refresh and rejuvenate.
Both men and women can benefit from rejuvenation treatments that help infuse growth factors directly into the skin such as our Stem Cell Microneedling treatment. Men and women that have photodamage skin and those that have mature skin can benefit from such a rejuvenation treatment.
These treatments can make your skin feel and look younger and can help improve the overall condition and texture of your skin.
