EGF:

EGF is a 6 kDa polypeptide growth factor that has been of particular interest because of its ability to promote wound and ulcer healing when applied topically. [1] A serum containing recombinant EGF produced in barley was examined in an open-label trial in 29 participants of age 30 years with photoaging. [2] The participants completed a survey rating improvements in brown spots, red spots, age spots, and skin smoothness on a 5-point scale, and differences were compared by paired t-tests. The study found that twice daily application of EGF serum for 3 months significantly improved brown spotting, skin texture, pore size, red spotting, and wrinkles versus baseline. 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 [1].

It is well known that EGF is a potent stimulator of cell proliferation of various cells including keratinocytes, fibroblasts and vascular endothelial cells . In addition, EGF stimulates fibroblasts to synthesize increased amount of VEGF and HGF. VEGF and HGF are known to be the most potent cytokines for the promotion of wound angiogenesis. Recent research has demonstrated that simultaneous administration of HGF and VEGF synergistically promotes new blood vessel formation, as compared to administration of each factor alone (fig.2) [2].

Different clinical studies in various clinical conditions like scar [3], senile purpura and dermatoporosis [4], hyperpigmentation[5], photo damage [6, 7], under-eye wrinkle and bag [8], radiation dermatitis in cancerous patient [9], leprosy [10] and even non-healing wound [11, 12] showed the beneficial use of topical EGF.

Thirty women with various ethnic backgrounds (Chinese, Caucasian and Latino) with an average age of 38 years old participated and mild-moderate visual facial aging signs Two sessions with 2-week intervals were completed using a derma stamp (transdermal drug delivery method) and 2 mL of growth factor serum (AQ Skin Solution recovery serum-contain a mixture of contains a mix of transforming growth factor beta (TGF-β), granulocyte monocyte-colony-stimulating factor, and platelets-derived growth factor with patented technology for extraction and composition at each session. The procedures were carried out for anti-aging and skin rejuvenation. Physician’s global assessment revealed growth factor-induced therapy resulted in skin rejuvenation in all races with 95% confidence, and this increased to 98% confidence for Latinos and Caucasians within the six weeks. Participants’ subjective rating revealed improvement of overall skin appearance with 95% confidence. Most noted improvements were in brightness, skin texture, and tightness [13].
