title: Improved texture and appearance of human facial skin after daily topical application of barley produced, synthetic, human-like epidermal growth factor (EGF) serum.
abstract: A three month, open-label, single center study was conducted to determine whether a uniquely derived serum containing barley bioengineered, human-like epidermal growth factor protein could improve visible signs of photodamage and aging in facial skin. Twenty-nine females, aged 39 to 75 years, with mild to severe, fine and course rhytids, photodamage, and pigmentation were enrolled. Subjects then applied the treatment serum per the prescribed protocol twice-daily for 3 months, in addition to the use of a basic sunscreen and facial cleanser. In-person clinical evaluations and subject self-assessment questionnaires were administered at each follow up visit. In addition, clinical photography was completed at baseline, and each subsequent visit. Clinical evaluations showed statistically 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, and continuing improvement trends for the duration of the study. The treatment serum was well tolerated with minimal treatment-related complications reported throughout. Efficacy of this novel serum and treatment protocol resulted in meaningful improvements in photodamage and visible signs of aging.
