Aesthetic Study: A New Regenerative Skin Care Regimen Containing Human Platelet Extract


About this study

The purpose of this trial is to evaluate the cosmetic role of novel anti-aging regenerative skin care product, human platelet extract (HPE), on skin rejuvenation. 

Skin aging is a natural part of human aging process caused by intrinsic and extrinsic factors, such as genetics, cellular metabolism, chronic light exposure and other toxins.  Cosmetological care for facial skin aging includes daily skin care, correct sun protection and aesthetic non-invasive procedures. 80 participants over the age of 40 years with moderate photoaging (dyschromic facial skin with fine lines and wrinkles) will be recruited from Mayo Clinic Center for Aesthetic Medicine and Surgery (CAMS) to participate in the study.  Subjects will be instructed to apply topical HPE to their entire face and decolletage twice daily, in the morning and at bedtime, for 12 weeks.  Subjects will also apply topical HPE versus marked-competitor (Skinceuticals CE Ferulic) to the dorsal hands in a non-randomized fashion.  Evaluations will include cosmetic questionnaires, standard photography and VISIA-CR 3D imaging.  Select subjects will also undergo skin biopsies, skin microbiome analysis and long-term evaluation at week 26 and week 52. This industry-sponsored, cosmetic study evaluates the role of topical HPE Skincare on overall skin appearance for aging skin.

A urine pregnancy test will be performed prior to the administration of the study drug to confirm negative results. If the urine pregnancy test is positive, the study drug will not be administered, and the result will be confirmed by a serum pregnancy test. Urine pregnancy tests will be performed by qualified personnel using kit.  Persons becoming pregnant during the study will continue to be monitored for the duration of the study or completion of the pregnancy, whichever is longer. Monitoring will include perinatal and neonatal outcome. Any SAEs associated with pregnancy will be recorded.
  • All skin phototypes ≥ grade I of Fitzpatrick’s classification.
  • Mild-to-moderate global face wrinkles and mild-to-moderate global fine lines based on a modified Griffiths’ 10-point scale.
  • Fully understanding of the requirements of the study and willingness to comply with the treatment plan, including laboratory tests, diagnostic imaging, and follow-up visits and assessments.
  • Volunteer willingness to discontinue any other anti-aging topical or parenteral treatments for the duration of the study.

  • Individuals with a history of any dermatological disease or condition, including but not limited to active atopic dermatitis, psoriasis, eczema, active seasonal allergies, collagen diseases, or skin cancer involving the treated sites within the past 6 months.
  • Cutaneous marks on the experimental area which could interfere with the assessment of skin reactions (pigmentation problems, scar elements, over‐developed pilosity, ephelides, and nevi in too great quantity, sunburn, beauty spots, freckles, etc.).
  • Participants with asymmetric photodamage on dorsal hands due to environmental exposures (i.e., golfing) and/or other skin lesions including burns or scars resulting in significant skin surface variability between dorsal hands.
  • Eczematous reaction still visible, scar, or pigmentary sequelae of previous tests on the experimental area.
  • Allergy to colophony or nickel.
  • Allergy or reactivity to drugs, food or cosmetic products previously observed, including perfumes or cologne products.
