The skincare industry is no stranger to advancements driven by innovative technology and scientific discoveries that aim to promote skin health and combat the ever-present problem of aging skin. Among the latest breakthroughs are the integration of stem cell components like growth factors, cytokines, and exosomes — naturally produced structures that have been known for their remarkable ability to facilitate growth, regeneration, and healing properties within living tissues, particularly those of the dermis layers.
Growth Factors in Skincare
Stem cells have long been understood to play a fundamental role in skin renewal and repair by releasing a plethora of bioactive molecules, which include growth factors and exosomes. As we age, however, the quantity and efficiency at which these stem cells are produced and carry out their roles within the body decline, leading to a reduction in their regeneration. This decline is the main concerning factor that contributes to the visible signs of aging and is an issue that underscores the importance of replenishing these essential signaling cells to ensure optimal skincare and vitality.
Understanding the intricacies of these bio-signals and their applications in skincare is, therefore, the first step in the search for effective, long-lasting solutions that work to holistically boost and support the health of your skin. As an introduction, growth factors are proteins that all types of cells secrete and are essential for the skin’s renewal and repair processes in addition to stimulating cell growth. Cytokines, on the other hand, regulate the immune system and aid in skin repair by influencing cellular communication and interactions. Exosomes are the nano-sized vesicles that cells release and which are rich in proteins, growth factors, and genetic material and which facilitate cell communication and promote healing and regeneration.
How They Work and Why They Matter
To delve even deeper, growth factors are typically manufactured by cells in the outermost epidermal layer and the deeper dermis, such as by fibroblasts that produce collagen, keratinocytes, which are the structural component of the epidermis, and melanocytes that make the pigment of cells. Growth factors are made naturally from these skin cells that focus on repairing any skin that has been damaged through environmental or aging factors. The collagen and elastin that they are responsible for activating within such skin cells provide the skin with its overall texture and shape, hence highlighting the importance of maintaining ideal levels of these proteins.
The older our skin gets, the thinner and less supple it becomes, accumulating pigmentation and resulting in a weakened appearance over time. And because aging skin has a diminished ability to produce growth factors compared to more youthful skin, products with a high concentration of such cellular proteins are necessary to help support skin rejuvenation. Cells can also come to harm and suffer micro-injuries from direct trauma or adverse environmental elements such as ultraviolet light and radiation from unprotected exposure to the sun. The stem cells in body tissues then secrete the proteins required to renew and repair this damage.
In skincare formulations, products enriched with stable growth factors offer a myriad of benefits, because they serve as key messengers in the intricate network of cellular
communication within the epidermis. By activating various cell types, growth factors can trigger the production of essential structural proteins that are vital for maintaining skin firmness, elasticity, and texture. When utilised in skincare products, their renewal properties can effectively address common concerns such as fine lines, wrinkles, and loss of elasticity, allowing visibly revitalized and more youthful-looking skin. Additionally, growth factors promote epidermal cell proliferation, an action that increases the number of cells, thus further facilitating regeneration and repair processes.
A brand that fully incorporates all of these stem cell components into its skincare and haircare products is CALECIM®, which arms itself with its revolutionary and patented formulation called PTT-6®. This PTT-6® ingredient is a powerhouse combination of potent growth factors, cytokines, and exosomes derived from ethically sourced tissues. With over 3,000 active stem cell elements and proteins per milliliter, PTT-6® has the potential to accelerate skin repair and even stimulate hair growth by building up a healthy extracellular matrix, encouraging moisture retention, and increasing skin cell production.
This level of potency in a stem cell culture is unique to CALECIM®’s source of extraction and kickstarts the cells within the body to renew, repair, and regenerate themselves. The impact of PTT-6® beneath and above the skin layers is wide-ranging, from contributing to an improved skin density that boasts a tightening and lifting effect, to a shortened epidermal cell turnover time that results in a more radiant skin as old cells are shed quicker and new ones rise to the surface.
CALECIM® products have undergone rigorous clinical testing to demonstrate their efficacy in accelerating post-procedure healing and improving skin conditions such as acne scarring and stretch marks. The Professional Serum, for example—a signature in their line-up—is enriched with PTT-6® and has garnered positive attention among clinicians for its ability to improve facial treatment outcomes and enhance the recovery process of patients. In-vitro trials have proven the many benefits of PTT-6®, which goes into every product in CALECIM®’s range, when used in conjunction with various skincare procedures, such as microneedling or laser resurfacing.
As technology continues to utilize the complexities of growth factors to the advantage of skincare, brands like CALECIM® can strategically harness the power of natural healing mechanisms to revolutionize anti-aging skincare. Through a thorough understanding of cellular biology and how growth factors play an undeniable role in skin health, the far-reaching goal to achieve a more youthful behavior for the skin—in both external appearance and internal performance beneath the surface—may not be so far, after all.
