Exosomes have become one of the most talked about ingredients in skincare, and Maysama's new Vitamin C Exosome Serum brings this technology into an everyday routine, alongside gold-stabilised vitamin C and plant-based collagen fragments.
But what are exosomes, what does the research say about them, and how do they fit alongside a treatment like LED light therapy? This guide breaks it all down.
What Are Exosomes?
Exosomes are tiny extracellular vesicles, essentially microscopic messengers that cells release to communicate with one another. They carry proteins, lipids and genetic material capable of influencing processes like collagen production and tissue repair.
A systematic review of exosomes in skin rejuvenation found they show promise for improving elasticity, softening the appearance of wrinkles, boosting hydration and addressing pigmentation, largely through their role in cell communication and repair signalling Exosomes in Skin Rejuvenation: Systematic Review.
A wider review of 34 studies on exosomes in cosmetic dermatology found similar potential for wound healing, scar prevention and skin regeneration, while noting that the field is still maturing, with challenges around standardisation and long-term clinical data Clinical Applications of Exosomes in Cosmetic Dermatology.
Meet the Vitamin C Exosome Serum
Rather than sourcing exosomes from animal or stem cell material, Maysama's serum uses phyto-exosomes, cultivated from green microalgae in a lab setting. This is a vegan, biomimetic technology designed to mirror the way skin cells naturally communicate and renew, rather than a naturally occurring extract.
Golden C: Gold-Stabilised Vitamin C
Pure vitamin C is notoriously unstable. It oxidises quickly and penetrates skin poorly on its own. Maysama pairs L-ascorbic acid with glutathione and a gold submicroparticle carrier, designed to keep it stable and help it absorb more effectively.
Based on supplier in-vitro testing of the raw ingredient, rather than the finished product, this delivery system is designed to support skin penetration and stability, though results on the finished serum itself have not been independently tested.
Phyto-Exosomes
These lab-cultivated, plant-derived vesicles are designed to support the skin's natural renewal processes and help carry other active ingredients deeper into the skin, rather than sitting on the surface.
Plant-Based Collagen Fragments
The formula also includes a human-identical type I collagen fragment, grown in plants rather than harvested from animals. This is included to support the skin's own collagen network alongside the vitamin C and exosome actives.
How the Vitamin C Exosome Serum Fits Alongside LED Light Therapy
If you already use an LED mask, or you are considering one, exosomes for skin and LED light therapy address skin renewal in different ways. LED light therapy works through photobiomodulation, using red and near-infrared wavelengths to stimulate your own cells and support natural collagen production. A topical antioxidant serum works alongside that process rather than replacing it.
Many skincare experts recommend layering a vitamin C serum before or after an LED session, since vitamin C plays a supporting role in collagen synthesis and helps protect the skin from oxidative stress during active repair.
Maysama's own suggested routine follows this order: cleanse, treat with the Vitamin C Exosome Serum, then use an LED device such as the Aura LED Light Therapy Face Mask to enhance results, before finishing with moisturiser and sunscreen.
Exosomes for Face and Exosomes Skin Care: Topical vs In-Clinic
Much of the current conversation around exosomes treatment for face concerns has focused on in-clinic options, often combined with microneedling. Exosomes microneedling and exosome injection procedures typically require several sessions and some downtime, since the skin barrier is intentionally disrupted.
An exosome serum used topically, such as Maysama's, is a different category of product. It is applied to intact skin as part of a daily routine, without the downtime or per-session cost associated with exosomes treatment in clinic.
This ease of use and reduced price is a reason why many users opt for serums instead of using exosomes with their microneedling treatment.
Are Exosomes Safe?
This is a fair question, and it is worth understanding the distinction between different types of exosome products.
In the United States, the FDA has issued a public safety notification confirming there are currently no FDA-approved exosome products for injectable or clinical therapeutic use, following reports of adverse events in patients treated with unapproved exosome products in a clinical setting. This notification specifically concerns products administered by clinics for therapeutic purposes, generally involving injection or use alongside microneedling.
A topical cosmetic serum, formulated and marketed as a cosmetic rather than a therapeutic treatment, sits in a different regulatory category to injectable or clinic-administered biologic products.
If you are considering any exosomes treatment, whether topical or in-clinic, it is worth understanding which category the specific product falls into and asking your provider directly.
The Bottom Line
Exosomes for skin represent a genuinely interesting area of dermatological research, with real potential for skin regeneration and repair support. Maysama's Vitamin C Exosome Serum brings this ingredient into a daily, at-home routine, alongside gold-stabilised vitamin C and plant-based collagen fragments, designed to work alongside your existing skincare and LED light therapy routine rather than replace either.
