Skincare ingredients are constantly evolving, but in the ever-advancing world of science and technology, two categories have proven their irreplaceable effects on cell regeneration and skin health, remaining timeless and future-proof: growth factors and peptides.
While often mentioned together, they play distinct roles in communicating with skin cells to signal repair, regeneration, and renewal. Furthermore, different growth factors and peptides have completely different mechanisms of action, leading to varied skincare results. Therefore, a deep understanding of these key ingredients is essential for effective anti-aging.
Imagine your skin as a city. Growth factors are the city planners, and peptides are the various departments and agencies that transmit crucial messages in the city. Each of them has a specific task to keep the city running smoothly.
| Growth Factors
Growth factors are a broad class of large protein molecules that are naturally present in the human body. They are closely related to the health of all our organs. For the skin, the main role of growth factors is to stimulate the growth, proliferation, and differentiation of various cells.
They act like the skin's "master repairers", precisely guiding skin cells such as fibroblasts and keratinocytes to heal wounds, repair damage, and maintain a youthful structure. Therefore, growth factors are crucial for healthy, vibrant skin.
Due to continuous scientific progress, new growth factors are constantly being discovered, so there is no exact number defining their types. However, some of the major growth factor families include:
-
The Epidermal Growth Factor (EGF) Family
Primarily involved in the growth and proliferation of epithelial cells.
-
The Fibroblast Growth Factor (FGF) Family
A large family that plays a role in embryonic development, wound healing, and blood vessel formation (angiogenesis).
-
The Insulin-like Growth Factor (IGF) Family
An important family of growth factors for mediating growth and development.
-
The Transforming Growth Factor-beta (TGF-β) Superfamily
A complex family of growth factors that can either promote or inhibit cell proliferation and play a key role in tissue repair.
-
The Vascular Endothelial Growth Factor (VEGF) Family
The main regulators of angiogenesis.
-
The Platelet-Derived Growth Factor (PDGF) Family
Very important for cell growth and division, especially for connective tissue cells.
| Peptides
Our skin's foundation is built from proteins. To maintain its texture, strength, and elasticity, it's essential to continuously replenish proteins in various parts of the skin, such as collagen and elastin.
Peptides, which are made of different amino acids, are part of these proteins. Different sequences of amino acids form various peptides that act as messengers between skin cells, specifically targeting and improving different skin concerns.
Years of research have shown that peptides can target and address specific skincare needs in a very precise way. They give instructions to skin cells on how to activate their building blocks to reverse various signs of aging. Simply put, using skincare products containing peptides is like sending a small team of messengers to the skin, ordering skin cells to perform specific functions, such as building collagen and elastin, smoothing wrinkles, providing intense hydration, promoting wound healing, neutralizing free radicals, and even reducing inflammation.
Since peptides are chains of amino acids with an enormous number of possible combinations, there is no exact number of peptide types. Peptides are typically classified based on the number of amino acids they contain (e.g., dipeptides, tripeptides, polypeptides) or their function in the body. In the context of skincare, peptides are generally divided into four main categories:
-
Signal Peptides
These peptides send messages to skin cells, encouraging them to perform certain functions. Their primary role is to stimulate the production of vital proteins like collagen and elastin, which are responsible for maintaining skin's firmness and elasticity. Palmitoyl pentapeptide-4 and Palmitoyl tripeptide-5 are common examples.
-
Carrier Peptides
Carrier peptides deliver trace elements such as copper and manganese, which are crucial for wound healing and enzymatic processes, to the skin. The most famous example is Copper tripeptide-1 (GHK-Cu), which also helps promote collagen synthesis and acts as an antioxidant.
-
Enzyme-Inhibitor Peptides
These peptides work by blocking the enzymes that break down proteins in the skin. For example, some peptides inhibit matrix metalloproteinases (MMPs), which degrade collagen and elastin. By protecting these proteins, they help maintain the skin's structural integrity. Soy peptides and Rice peptides are prime examples known to inhibit MMPs.
-
Neurotransmitter-Inhibitor Peptides
Often called "Botox-like" peptides, they work by temporarily blocking the signals that cause muscle contractions. By relaxing facial muscles, they help reduce the appearance of expression lines and wrinkles, especially around the eyes and forehead. A common example is Acetyl hexapeptide-8.
Growth factors and peptides are naturally occurring elements in the skin. However, as we age, the production of these vital molecules slows down, leading to visible signs of aging like wrinkles, fine lines, and sagging. Applying these ingredients topically creates a synergistic effect with the skin's natural processes, helping to restore its communication network and prompting skin cells to behave more like their youthful selves.
Furthermore, because they are non-irritating, they can be safely used on all skin types, even those with inflamed skin conditions such as acne, eczema, and rosacea!
Below, we will introduce you to some of the most common growth factors and peptides found in skincare products.
Epidermal Growth Factor (EGF) is a powerful signaling protein that effectively stimulates the growth, proliferation, and differentiation of skin cells, especially keratinocytes, making it crucial for maintaining skin health and integrity. It accelerates the repair process for damaged skin, including minor wounds and cellular damage caused by inflammation and sensitivity. Additionally, by stimulating cell renewal and promoting the synthesis of collagen and elastin, it helps to diminish fine lines and wrinkles, improve skin elasticity, enhance firmness and plumpness, and improve skin barrier function, resulting in a more youthful, smooth, and refined complexion.
Clinical data shows that EGF has a significant ability to improve fine lines, wrinkles, radiance, and overall appearance. After three months of continuous use, it can significantly increase skin hydration by up to 69% and improve skin elasticity and firmness by 13%. For atrophic acne scars, a one-month use of EGF resulted in an average improvement of 18.97% in scar volume, and after three months, the average improvement was 27.40%!
｜ Benefits
- Promotes skin cell proliferation and regeneration
- Accelerates wound healing
- Improves the appearance of fine lines
- Increases skin hydration
