Exosomes have become one of the most hyped concepts in modern aesthetics. But what are they really, what is the evidence, and how are they used correctly?
What are exosomes?
Exosomes are extracellular vesicles — tiny bubbles (30–150 nm) secreted by cells. They contain proteins, RNA, lipids and signalling molecules. Stem-cell exosomes contain "signals" that promote regeneration.
How are they used?
- Topically: Applied after microneedling or laser — most common in Sweden
- Injection: Prohibited in the EU — no CE marking of injectable exosome products
- Scalp: For hair loss, in combination with PRP or microneedling
Legal status in the EU/Sweden
Injected exosomes are classed as advanced therapy medicinal products (ATMPs) and require approval. No such preparation is approved for aesthetic injection in the EU in 2026. Clinics that "inject exosomes" are operating in a grey area — often based on unapproved imports.
Topical application (legal)
- Applied to the skin after microneedling or fractional laser
- Penetrates through the microchannels
- Stimulates cell renewal
Evidence
Several in vitro and animal studies show regenerative effects. Clinical studies in humans are still limited but promising — accelerated healing after laser, improved skin texture[1].
Price
- Topical exosome treatment after a procedure: +SEK 1,500–3,500
- Standalone: rarely, since absorption requires microchannels
Who are exosomes suitable for?
- ✅ After microneedling/laser for accelerated healing
- ✅ Scalp treatment for hair loss
- ✅ You want to try the latest regenerative methods
- ❌ A replacement for established treatments
- ❌ You are looking for an injection treatment — not legally available in the EU
Warnings
- ❌ Avoid clinics that market "exosome injections" — illegal in the EU
- ❌ Obscure brands from unknown sources
- ✅ Choose a verified topical product from an established brand
