Exosomes in Skincare: Dr. Daniel Gould Featured in The Quality Edit

Beverly Hills plastic surgeon Dr. Daniel Gould, MD, PhD was recently featured in The Quality Edit discussing the science behind exosomes, how different sources compare, and what consumers should understand as exosome-based products become increasingly common in regenerative skincare.

Exosomes are microscopic vesicles that carry biological signals between cells, including proteins, lipids, RNA, and other molecules involved in processes such as repair and inflammation. While the term has become increasingly prominent in beauty and skincare, Dr. Gould emphasizes that not all products marketed as exosomes are biologically equivalent.

One important distinction is the source. Dr. Gould explains that human-derived exosomes, typically sourced from stem cells or platelets, contain biological material that human skin cells naturally recognize. Much of the existing clinical research is concentrated in this category. Plant-derived alternatives may offer advantages from a regulatory and formulation perspective, but the current evidence does not establish them as biologically equivalent to human-derived exosomes.

The article also highlights what patients and consumers should consider when evaluating exosome products. Dr. Gould recommends looking beyond marketing terminology to factors including the source of the exosomes, particle characterization, formulation and stability, and how the product is intended to be used. Because exosomes are fragile, proper preservation and delivery can be just as important as the presence of exosomes themselves.

Dr. Gould notes that some of the strongest evidence for exosomes relates to their use alongside professional treatments. Procedures such as microneedling, laser treatments, and radiofrequency create a controlled healing response, and exosomes may help support that recovery process. This differs from treating exosomes as a conventional daily serum or expecting a topical product alone to produce dramatic regenerative results.

As regenerative aesthetics continues to evolve, Dr. Gould encourages a science-driven approach to emerging technologies. Exosomes represent a promising area of research, but their effectiveness depends on the biology, quality, concentration, stability, and delivery of the specific product. Understanding those distinctions can help separate meaningful regenerative applications from products relying primarily on the popularity of the term.
