Exosome Facials: What You Need to Know About the Latest Skincare Trend

A recent investigation by 5 News has raised concerns about UK clinics using illegal human-derived exosomes in so-called “next-gen” facials — a treatment trend exploding across TikTok and social media. These facials promise younger, smoother and more radiant skin, but experts warn that many consumers don’t actually know what’s inside these powerful serums.

With exosome treatments rapidly appearing on clinic menus nationwide, clarity and transparency are becoming more important than ever.

Below, trusted voices in medical aesthetics share expert insight to help decode the headlines and guide consumers safely.

Expert Insights on Exosome Safety

Dr Toni Phillips, Group Medical Director at SK:N Clinics

“In my years of using exosomes in clinic I only use high-quality brands from trusted suppliers. Human-derived exosomes are not illegal per se in the UK for topical application but they must not be injected, and sensationalist headlines can mislead patients. I always advise patients to ask for written product sourcing information and to check exactly what the exosome product is and where it comes from.”

Dr Phillips highlights a key issue: while topical exosomes are not banned, poor regulation means patients must be proactive in checking product quality and sourcing.

Zoe Budd, Founder of ZOBU (luxury aesthetic concierge)

“I use topical E50 salmon-derived exosomes from Korea, which contain five billion particles per vial. Recently a client asked for a specific ‘plant-based’ exosome brand for their facial - but after contacting the manufacturer, I discovered it actually contained 12.5% human material! Transparency in sourcing is essential for patient safety and brand credibility.”

This example shows how misleading marketing claims can be — even products labelled “plant-based” may contain human-derived components.

Why This Story Matters

Exosome facials have rapidly become a must-try anti-ageing treatment, praised for boosting collagen, improving texture, and supporting skin repair. But with the market growing faster than regulation can keep up, questions around:

  • ingredient sourcing

  • legality

  • safety

  • transparency

are now at the forefront.

As with any trending treatment, patients should take extra care to verify that clinics use reputable suppliers and can clearly explain what is being applied to the skin.

Exosomes may hold exciting potential — but only when used safely, ethically, and with full transparency.

Patient Q&A: Exosome Facial Safety

What exactly are exosomes?

Exosomes are tiny particles naturally released by cells. They contain growth factors and signals that can help stimulate skin repair and rejuvenation when applied topically.

Are exosome facials legal in the UK?

Topical exosome treatments are not illegal in the UK. However, injecting exosomes is not permitted, and sourcing standards are not yet strictly regulated.

Are all exosome products the same?

No. Exosomes can come from human, plant, or animal sources (such as salmon), and product quality varies widely. Some brands marketed as “plant-based” have been found to contain human material.

Can exosomes be dangerous?

Risks arise when:

  • The source of the exosomes is unclear

  • The product is falsely advertised

  • Clinics use unverified suppliers

  • Exosomes are injected rather than used topically

What results can I expect?

Patients often report:

  • Brighter skin

  • Improved texture

  • Reduced redness

  • Enhanced healing after treatments like microneedling

Results vary depending on the product used and the clinic’s technique.

Safety Checklist: Questions to Ask Before an Exosome Facial

Before booking an exosome facial, ask your practitioner:

What is the exact exosome product you use?
Ask for the full product name and manufacturer.

Is the product human-derived, plant-based, or animal-derived?
Make sure the clinic can explain clearly and without hesitation.

Can I see written evidence of sourcing and safety data?
Reputable clinics should be able to provide this.

Is this product licensed or cleared for topical cosmetic use?
If the answer is vague or unclear, be cautious.

Has the product been independently tested?
Look for third-party testing or certificates of analysis.

How are exosomes applied during the treatment?
Remember: in the UK, exosomes should not be injected.

Do you have training and experience using this brand?
Experience matters, especially with emerging treatments.

What results should I realistically expect?
Avoid clinics promising dramatic, guaranteed outcomes.

What aftercare do I need?
Proper aftercare supports the best skin response.
