Discover the emerging star in skin-transforming skincare: Growth Factors. While many skincare brands highlight hyaluronic acid as the ultimate hydration ingredient, have you explored the benefits of growth factors? These active components represent the latest advancements in skincare technology. Growth factors have been proven to significantly slow aging signs and promote skin cell regeneration for a more youthful appearance. In essence, growth factors in skincare are essential for individuals over 30 whose skin is beginning to show aging and environmental damage signs.
GROWTH FACTORS 101
The good news: Growth factors are proteins naturally present in the body that stimulate cellular renewal. Our cells naturally release growth factors as signaling molecules to maintain cellular health and promote division. When damage occurs, cells produce growth factors to signal surrounding cells for repair.The bad news: As we age, the body's natural growth factor supply diminishes.But there's hope! Applying growth factors topically triggers a repair message in the stratum corneum, which travels to the dermis through a signaling cascade, encouraging fibroblasts to produce collagen and rejuvenate damaged or aging skin. Initially, growth factors were used in burn centers to aid healing.Think of it this way: In aging skin, cell renewal slows down, akin to a battery needing a recharge — and growth factors serve as the recharge. They signal collagen production and help prevent skin from sagging, loosening, and wrinkling, making them crucial for treating aging skin. After all, we're all aging in some way, right?
CONSIDER THE SOURCE
In the past, growth factors were most bio-active when sourced from humans (like adipose tissue, amniotic membrane, baby foreskin) as they align with the growth factors naturally found in human skin. However, advancements in technology have enabled the creation of peptides identical in chemical structure to growth factors. Although these lab-synthesized peptides are not derived from humans or animals, they have been shown to speed up skin renewal, diminish lines and wrinkles, enhance skin texture, and reverse environmental damage. How do they achieve this? Growth factors promote cell proliferation, leading to increased cell growth and division, and they also prevent cell apoptosis, or cellular death.
GROWTH FACTORS IN LE MIEUX SERUMS
Le Mieux was a pioneer in incorporating growth factors into skincare. Their serums include lab-synthesized peptide forms of protein growth factor that are neither human-derived nor animal-derived. These growth factors function by sending signals to nearby cells to stimulate cellular renewal.For instance, Le Mieux serum formulations contain sh-oligopeptide-1, also known as epidermal growth factor (EGF), and palmitoyl tripeptide-5, known as transforming growth factor (TGF).In Le Mieux formulas, TGF is considered "preventative," acting as a "Collagen Protector" to prevent collagen breakdown and protect existing collagen. TGF is ideal for formulations aimed at preventing or addressing early signs of aging, such as fine lines.EGF is regarded as "reparative" or "regenerative," known as the "Youth Molecule," helping to reverse existing skin damage by promoting collagen production and accelerating skin renewal. EGF is best for formulations targeting damaged, irritated, sensitive skin, as well as deep wrinkles and advanced aging signs. In anti-aging formulations, growth factors complement other ingredients and are often combined with peptides, hyaluronic acid, antioxidants, and stem cells.
