Exosomes & Laser for Acne Scars--BENEV Announces Investigative Report on Combination Treatment with Human Adipose Tissue Stem Cell-Derived Exosomes and Fractional CO2 Laser for Acne Scars

On January 7, 2021, BENEV Company, Inc., an FDA-registered cosmeceutical manufacturer of a globally recognized medical professional line, along with its Medical Advisory Board comprised of five global medical leaders, announced that that the 12-week Prospective, Double-Blind, Randomized, Split-Face Investigative Report on Combination Treatment with Human Adipose Tissue Stem Cell-Derived Exosomes and Fractional CO2 Laser for Acne Scars by ExoCoBio Inc., an equity-invested partner of BENEV, was published online on October 19, 2020, in Acta Dermato-Venereologica ( This open-access report outlines the investigative study that was conducted by a team of scientists and physicians including Hyuck Hoon Kwon, Steven Hoseong Yang, Joon Lee, Byung Chul Park, Kui Young Park, Jae Yoon Jung, Youin Bae, and Gyeong-Hun at Oaro Dermatology Institute (Seoul, South Korea); Guam Dermatology Institute (Guam, USA); Department of Dermatology, Dankook University, College of Medicine (Cheonan, South Korea); Department of Dermatology, Chung-Ang University, College of Medicine (Seoul, South Korea); and the Department of Dermatology, Dongtan Sacred Heart Hospital, Hallym University College of Medicine (Hwaseong, South Korea). Researchers involved in this study evaluated the clinical efficacy and safety of adipose tissue stem cell-derived exosomes as an adjuvant therapy after application of fractional CO2 laser for acne scars. 25 patients consisting of 18 men and 7 women, between ages 19 and 54, 12 with Fitzpatrick Skin Type 3 and 13 with Fitzpatrick skin type 4 and atrophic acne scars, underwent the 12-week prospective, double-blind, randomized, split-face trial. Each received three consecutive treatment sessions of fractional CO2 laser to the whole face, with a follow-up evaluation, and a post-laser split face regimen, where one side of each patient's face was treated with an adipose tissue stem cell-derived exosome gel. Exosomes in this study were acquired from human ASC-CM (adipose-derived stem cell-conditioned media) by ExoSCRT™ technology ( developed by ExoCoBio Inc. (, and the other side of the face was treated with control gel.

Findings revealed that the adipose tissue stem cell-derived exosome-treated sides of the face had achieved a significantly greater improvement than the control sides at the final follow-up visit (percentage reduction in échelle d'évaluation clinique des cicatrices d'acné scores: 32.5% vs 19.9%, p<0.01). Treatment-related erythema was milder, and post-treatment downtime was shorter on the applications of human adipose tissue stem cell-derived exosome-treated side.

This investigative study proved that a variety of applications of human adipose tissue stem cell-derived exosomes can serve as a novel cell-free therapeutic strategy in the regenerative and aesthetic medical fields and demonstrated the suitability of adipose tissue stem cell-derived exosomes as an adjuvant treatment modality in combination with fractional carbon dioxide laser for the treatment of acne scars.

"The science is clearly demonstrating that exosomes are the wave of the future, not just for aesthetics, but for many other areas of medicine, and the richest source of this material, by far, is adipose tissue," says Randy Miller, MD, FACS, Member of the BENEV Medical Advisory Board. Dr. Randy Miller is a board-certified cosmetic and reconstructive plastic surgeon practicing in Miami, Florida, USA. As one of the nation’s leading innovators in aesthetic surgery of the face, hand, breast, and body, and a pioneer of reconstructive surgery and stem cell procedures, Dr. Miller is certified by the American Board of Plastic Surgery and the American Board of Otolaryngology--Head and Neck Surgery.

Facial atrophic acne scarring is a psychologically damaging condition that can cause emotional, mental, and social disability. "With a huge percentage of the world population struggling with this condition, the need for widening of therapeutic options was astoundingly clear," says Diane Duncan, MD, FACS, also a Member of the BENEV Medical Advisory Board. Dr. Duncan is an award-winning, globally recognized plastic and reconstructive surgeon, who added, "While ablative fractional carbon dioxide laser resurfacing has demonstrated clinical efficacy in acne scar treatments, patients have sustained side-effects during post-procedural wound healing and had demanded improvement. The adjuvant application of adipose-derived stem-cell-conditioned medium with synergistic effects in augmenting treatment responses and reducing adverse effects through its potential to accelerate tissue rejuvenation is a victory for those suffering."

The sentiments have been echoed by many other medical professionals, including, J.D. McCoy, NMP, also a Member of the BENEV Medical Advisory Board. Dr. McCoy’s patient roster includes professional athletes who do not have time for extended downtime and need to recover quickly.

"Since implementing the addition of Exosome Regenerative Complex powered by ExoSCRT™ into my protocol, I've observed a significant improvement in the speed of healing, skin quality, and comfort during recovery," said Richard Jin, MD, PhD, also a Member of the BENEV Medical Advisory Board. "Patients suffering from acne scarring range in all ages, and the pain that they feel is very real. Ensuring that my patients receive the best treatment results with the least amount of downtime and discomfort is non-negotiable, and that's why I choose to integrate Exosome Regenerative Complex powered by ExoSCRT™, into all of my treatments."


Exosomes are lipid-bilayer-enclosed extracellular vesicles (EVs), 30–200 nm in diameter, produced by all cells and present in all body fluids. They are regarded as an essential mediator of intercellular communication by transferring proteins and/or genetic material between cells. Several studies have shown that mesenchymal stem cell-derived exosomes carry the essential properties of mesenchymal stem cells suggesting that exosomes may be a compelling alternative in regenerative and aesthetic medicine, as they would avoid most of the problems associated with live mesenchymal stem cell-based therapy. Interestingly, recent studies have shown that human adipose tissue stem cell-derived exosomes possess the critical properties of stem cells and are as potent as mesenchymal stem cells in the repair of various organ injuries.


BENEV's Exosome Regenerative Complex ( powered by ExoSCRT™ was developed and designed in tandem with one of the largest exosome research companies in the world, ExoCoBio ( The intensive dual action complex is quickly absorbed into the skin, delivering the concentrated power of over 2.5 billion lyophilized exosomes, potent growth factors, peptides, co-enzymes, minerals, amino acids, and vitamins. The paraben-free, steroid-free, and hypoallergenic patented technologies and ingredients are clinically proven to rejuvenate and regenerate the skin. "Lyophilizing exosomes maximizes topical therapeutic potential--making them ideal for treatments," says Richard Goldfarb, MD, FACS, also a Member of the BENEV Medical Advisory Board.


ExoCoBio's ExoSCRT™, is an innovative patented purification method of separating and refining 0.1 pure exosomes from stem-cell-conditioned media. The concentration of materials is significantly greater than what can be achieved with a product such as platelet-rich plasma (PRP). Studies have shown that this product increases fibroblast production by 180% and collagen production by 300%.


Richard Jin, MD, PhD, BENEV's Chief Medical Director, studied at the Boston University School of Medicine, Harvard Medical School, and the University of California Irvine. He completed research in the areas of cardiovascular disease, pulmonary hypertension, antioxidant enzyme properties, cell signaling, cellular redox mechanisms, free radical-induced oxidant stress, platelet biology, growth factors, and wound healing.
