Future Skin: Why We’re Betting on Postbiotics Over Exosomes
Every trend caster in the beauty space has crowned exosomes a revolutionary new ingredient in topical skincare, offering a cutting-edge approach to skin rejuvenation and repair. For those non beauty nerds among us, let’s define what an exosome actually is:
Exosomes are microscopic particles derived from human stem cells that serve as messengers between cells, carrying essential proteins, lipids, and genetic material that promote healing and regeneration.
Where do they come from? Human exosomes are derived from stem cells from various parts of the body such as bone marrow, fat tissue, umbilical cord tissue, and amniotic fluid.
Theoretically, exosomes have the power to do the following in skincare:
- Stimulates Collagen and Elastin Production – Exosomes deliver growth factors that encourage fibroblast activity which translates into firmer skin.
- Enhances Cellular Repair – supports the skin’s natural repair mechanisms, reducing inflammation and accelerating healing.
- Improve Hydration and Barrier Function – Exosomal lipids and peptides strengthen the skin barrier, boosting moisture retention and protection against environmental stressors.
- Reduce Signs of Aging – Their regenerative properties help smooth fine lines, improve texture, and restore glow.
While we champion innovation, we have concerns over the topical power of exosomes at this moment in time because the technology is still emerging. Questions we have regarding the topical efficacy of this power ingredient.
Does it effectively penetrate the skin barrier when applied topically? Exosomes are relatively large compared to other skincare ingredients.
In addition, exosomes are unstable and can degrade easily due to factors like temperature, pH, and storage conditions. If they lose their bioactivity before application, will they actually provide the intended skin benefits?
Currently, exosome-based skincare is not strictly regulated, and there are inconsistencies in how brands formulate and source exosomes. Some products may contain insufficient or inactive exosomes.
What we do feel confident in: The power of our Biodiveristy Broth consisting of S. epidermidis Postbiotics (the nutrition sourced from this beneficial skin bacteria):
Both exosomes and Staphylococcus epidermidis (S. epidermidis) postbiotics are working at the cellular level to enhance skin regeneration, repair, and improve overall skin health. While they perform differently, both leverage biological signaling to optimize skin function.
The postbiotics from this bacterium have the proven power to:
-
Regulate immune responses, reducing inflammation and sensitivity.
-
Produce antimicrobial peptides that help prevent acne and infections.
-
Enhance cellular repair by promoting wound healing and skin renewal.
-
Strengthen the barrier function which improves the natural HA and hydration in skin.
-
They are highly stable and effective.
In the never-ending battle for flawless skin, Staphylococcus epidermidis is the tiny, invisible, unsung superhero you never knew you needed. And, it is profoundly at the cutting edge of skincare science.
