Exosomes have quietly become one of our favorite finishing touches — the regenerative add-on we reach for at the end of a resurfacing treatment. But there's a lot of hype (and a fair amount of misinformation) around them, so here's the honest version: what exosomes actually are, how we use them, and where they genuinely help.
What exosomes actually are
Exosomes are not new. These tiny vesicles were first described about twenty-five years ago, and for a long time they were dismissed as cellular waste — little bubbles that cells released and discarded.
Research has since flipped that picture. We now understand exosomes as messengers: cells use them to communicate. Each one carries a cargo that reflects the cell it came from — proteins, lipids, and genetic signals like mRNA and microRNA. In skincare, the exosomes we use are prized because that messenger cargo can help signal for collagen and deliver growth factors to skin and scalp.
How we actually use them — as an add-on, not a shortcut
This is the part the marketing usually skips. Exosomes are not a standalone facial or a magic serum you rub in at home. In our practice they're applied topically, immediately after a treatment has briefly opened the skin's surface — that's what lets them absorb into the deeper layers instead of sitting on top.
- Always paired with a procedure that creates microchannels or controlled resurfacing — never sold as an injectable in our office.
- Applied at the end of the treatment, over freshly treated skin, so the messenger cargo reaches the layers doing the repair.
- Considered case by case — a good add-on for the right treatment and skin, not an automatic upsell.
A note on safety: there is no FDA-approved injectable exosome product, and the FDA has warned against unapproved injected exosome therapies. What we're describing here is topical use as an add-on to a resurfacing procedure — a different thing. — Dr. Lusanik Galustian, MD
Why they pair so well with resurfacing
The treatments we most often add exosomes to all share one feature: they briefly disrupt the skin's surface so it can rebuild stronger. That's also the ideal moment to introduce a regenerative signal.
- Morpheus8 — radiofrequency microneedling that remodels deeper, so the collagen signal has somewhere to go.
- CO2 CoolPeel — fractional laser resurfacing that renews the surface with minimal downtime.
- Microneedling — the classic collagen-induction channel-maker.
Wondering which resurfacing treatment is right in the first place? We break down how Morpheus8 and CO2 compare in a separate guide — exosomes can layer onto either.
Exosomes don't replace a treatment. They make the most of the window a treatment opens.
Skin and hair
Because exosomes work by signaling — not by forcing a single result — the same messenger idea applies to more than fine lines. On the skin, the goal is smoother texture, tone, and a collagen boost as it heals. On the scalp, exosomes are applied over the treated area to support the follicle environment.
If skin renewal is your goal, exosomes fit naturally into an exosome treatment paired with resurfacing — and they sit in a family of regenerative boosters we may reach for, alongside options like a salmon-DNA skin booster, depending on your skin. If hair thinning is the main concern, it's worth comparing exosomes with PRP hair restoration, which has a longer track record for the scalp — we'll talk through both honestly at a visit.
- Exosomes are cell-derived messenger vesicles that carry proteins, lipids, and growth-factor signals.
- We use them as a topical add-on, applied right after resurfacing — never as an injectable in our office.
- They pair best with Morpheus8, CO2 CoolPeel, and microneedling, which open a repair window.
- They support both skin renewal and the scalp; for hair, PRP is the more established option.
- There is no FDA-approved injectable exosome product — topical add-on use is a different thing.
