Epidermal growth factor (EGF)

EGF is a single polypeptide of 53 amino acid residues which is involved in the regulation of cell proliferation. EGF is a message telling cells that they have permission to grow. This molecule can stimulates fibroblasts to synthesize increased amount of pro-angiogenesis factors ) VEGF and HGF( and also increase keratinocyte and fibroblast proliferation [1]. EGF (by activating MAPK pathway) can influence the keratinocyte migration machinery that determines the speed of re-epithelialization and keratinocyte contraction [2]. EGF, formulated in skin care product assessed to show the ability of fibroblast cytokine production [1].  Figure 1. Show the effect of barely, human liked EFG serum in the clinical study on 29 women, aged 39-75 with mild to severe wrinkle, fine and course rhytids, photodamage, and pigmentation. The results indicated significant improvement in the appearance of fine lines and rhytids, skin texture, pore size, and various dyschromatic conditions apparent within the first month of use [3].

Different clinical studies in various clinical conditions like scar [4], senile purpura and dermatoporosis [5], hyperpigmentation[6], photo damage [7, 8], under-eye wrinkle and bag [9], radiation dermatitis in cancerous patient [10], leprosy [11] and even non-healing wound [12, 13] showed the beneficial use of topical EGF.

Insulin-like growth factor (IGF)-1 is a growth factor that can influence fibroblast functioning, with effects including the inhibition of collagenases and the induction of collagen expression. The graph in below show result of clinical study on 617 subjects, perceived age and skin wrinkling were assessed from facial photographs, and IGF-1 were measured in serum. Skin wrinkling decreased when the ratio of IGF-1 increased [14].


The basic FGF (FGF-2) reduces and prevents expression lines and wrinkles through the activation of new skin cells and stimulates the proliferation of cells of mesodermal, ectodermal, and endodermal origin, mainly fibroblasts and keratinocytes. In recent years, topical and injectable growth factors have emerged as an intriguing therapeutic modality that can be harnessed for esthetic and medical purposes. A group of researchers, who also studied FGFs, aimed to evaluate an in vivo method for aged skin rejuvenation through direct injection of intradermal FGF-2. The following rejuvenating effects were observed: improvement of skin smoothness, atrophied skin thickness, and improved viscoelasticity. The changes of viscoelasticity pre- and post-treatment were comparable to an age difference of more than 20 years [15].

Vascular endothelial growth factor (VEGF) is a signaling protein that promotes the growth of new blood vessels. VEGF forms part of the mechanism that restores the blood supply to cells and tissues when they are deprived of oxygenated blood due to compromised blood circulation. VEGF, Is the most frequent stem cell (SC) growth factor secretion and play important role in angiogenesis to recover injuries. Topical application of cream contains mixture of growth factors including VEGF, PDGF-A, G-CSF, HGF, IL-6, IL-8, and TGF-beta (1) on 20 subjects for facial rhytides showed significant success between baseline and 3-month scores [16].

Extracellular matrix proteins: Collagen, Fibronectin and Elastin

Collagens are the most abundant components of the extracellular matrix and many types of soft tissues. Elastin is another major component of certain soft tissues, such as arterial walls and ligaments. Many other molecules, though lower in quantity, function as essential components of the extracellular matrix in soft tissues. Fibronectin with its muldomain structure plays a role of “master organizer” in matrix assembly as it forms a bridge between cell surface receptors, e.g., integrins, and compounds such collagen, proteoglycans and other focal adhesion molecules. It also plays an essential role in the assembly of fibrillin-1 into a structured network. They all contribute to the structure of the extracellular matrix (ECM) and modulate cellular functions such as adhesion, differentiation, migration, stability of phenotype, and resistance towards apoptosis [17]. Figure.5. in below show the clinical result of topical cream formulated with multiple growth factors, antioxidants, and a collagen-building peptide—ingredients that have been shown to increase collagen levels and provide long-term aesthetic benefits

Sodium hyaluronate:

Hyaluronic acid (HA) acts as a biologic humectant, thus retaining water in the skin, making HA useful as a topical moisturizing ingredient. HA is a valuable ingredient to improve facial appearance in women with poor skin plumpness, decreased skin hydration, and photoaging. It has been used both topically and orally for appearance improvement. HA is multifunctional, even possessing a role in immune modulation in disease and as a post-procedure treatment in facial resurfacing. Changes occur in HA with aging such that a HA-based moisturizer might improve facial appearance through topical application. Hyaluronic acid has two salt forms: sodium hyaluronate and potassium hyaluronate. As the name suggests, sodium hyaluronate is the sodium salt version. The current formulation contains hydrolyzed 50 kDa HA and 10–1000 kDa sodium hyaluronate. This size of the HA allowed it to penetrate into and through the stratum corneum [18]. These humectant ingredients produced an immediate increase in the water-holding capacity of the skin, as demonstrated in fig.6 by the investigator assessments in clinical study on forty females 30–65 years of age.

This African-American female demonstrated increased light reflection from the face, especially from the medial cheeks, improving overall skin tone after 6 week

Multi peptides Miracle:

Although the effect of each ingredients explained above, different studies showed the synergic effect of application multiple growth factors like a mixture along with some specific materials like HA, ……. To boost the effect on skin by co-stimulation, especially for person plus forty. Topical application of human sourced of 5 GFs contain IGF1, KGF, EGF, SOD1 and bFGF with HA and combination of stem cell conditioned medium on 23 Korean women, show in fig.7 and demonstrate significant improved in periobital wrinkles assessed by visiometer [19].

The before and after clinical study by using bone marrow derived stem cell conditioned medium serum on 40 Indian women aged 35 to 60 showed improvement in fine lines, wrinkles, crow’s feet, evenness of skin tone, skin firmness / laxity, hydration of skin, homogeneity of age spots, and visible pores. this study was followed for 90 days and no adverse effect was reported [20].

Fig.9. Improvement in fine lines and wrinkles was felt by 73.68% subjects (p = 0.0018); Improvement in skin tone was felt by 65.79% subjects (p = 0.0258); Improvement in skin hydration was felt by 94.74% subjects (p < 0.0001); Improvement in visible pores was felt by 63.14% (p = 0.0524) and 65.79% (p = 0.0258)
