MCT Exosomes for Skin Quality and Hair Support

Available at our Chislehurst and London clinic.

This is a regenerative treatment prepared from your own blood. Using the Metacell Tech® (MCT) system, we refine autologous exosomes – naturally occurring messengers your cells already produce – so they can be returned to the skin or scalp where support is needed.

Unlike many high-street “exosome” facials (often cosmetic products that cannot be injected), MCT Exosomes are an autologous medical preparation, used under medical supervision after consultation.

 

MCT Exosomes | Dr Liesel Holler

What Are MCT Exosomes?

Exosomes are tiny messengers that help cells communicate. With MCT, we take a blood sample, prepare platelet-rich plasma, then process it through Metacell Tech® using controlled light and temperature. The exosomes prepared are naïve and autologous – from you, not from plants, animals, another person, or a lab-engineered vial.

They can be applied by microneedling or superficial injection, depending on what we agree is appropriate.

How is this different from PRP?

PRP uses your platelet-rich plasma. MCT Exosomes are prepared from that same blood sample through further processing, so we can work with a more refined regenerative fraction. Many patients have MCT Exosomes as part of a plan that may also include enhanced PRP (MCT Plasma). We’ll advise which approach suits you – there’s no one-size-fits-all.

MCT Exosomes | Dr Liesel Holler

What can they help with?

After assessment, MCT Exosomes may be considered for:

  • Skin quality, fine lines and early texture change
  • Dull or tired-looking skin
  • Support after other skin treatments (where appropriate)
  • Thinning hair / reduced density (scalp)

We’ll only recommend this if it’s right for your concern – and say so honestly if it isn’t.

What will the results look like?

Skin: a fresher look may appear in the days after; deeper changes in quality often build over 6–12 weeks

Hair: any improvement is gradual – often assessed from around 8–12 weeks, with clearer change over 3–6 months

Best results usually come from a course of 3 sessions, about 4 weeks apart. Individual results vary. Maintenance may be discussed later.

Procedure

The process starts with a simple blood draw. Your blood is then processed to extract PRP, which is fed into the MCT device. The exosomes are harvested using controlled heat and light. Once ready, the exosomes are applied to your skin or scalp, either through microneedling or superficial injections, depending on the area and desired outcome.

Is It Painful?

Most patients find the treatment very tolerable. You may feel slight pressure or a pricking sensation during the blood draw or microneedling, but any discomfort is minimal and short-lived. A topical numbing cream is applied beforehand to ensure comfort throughout.

How Long Does It Take?

60-90 minutes. This includes the blood draw, exosome isolation, and application.

How Long Do Results Last?

Results can last 6 to 12 months, depending on your skin condition, age, and lifestyle. Maintenance treatments are recommended every few months to sustain collagen production and cellular repair.

How Do MCT Exosomes Work?

MCT Exosomes work by delivering powerful cellular messengers directly into the skin to stimulate regeneration, reduce inflammation, and promote healing. These nano-sized vesicles, derived from your own blood and refined through Metacell technology, carry growth factors and proteins that reprogram damaged or ageing cells, resulting in improved skin quality, tone, and texture.

What Are the Clinical Benefits and Applications?

MCT Exosomes can be used across the face, neck, décolletage, and scalp to:

  • Improve skin elasticity and hydration
  • Enhance healing post-laser or microneedling
  • Treat fine lines, dullness, and uneven tone
  • Reduce redness and inflammatory conditions
  • Support hair growth in thinning areas
  • They are especially beneficial for those with sensitive, reactive or ageing skin.

Are the Results Backed by Research?

Yes. The MCT system is supported by extensive clinical data demonstrating its ability to stimulate fibroblast activity, improve skin barrier function, and accelerate healing. Studies show significant improvement in skin texture, tone, and elasticity, especially when used as part of a multi-session regenerative programme. The treatment is CE-certified and backed by real-world results in aesthetic medicine.

Firstly, this is a friendly and welcoming clinic.

Dr Liesel is not only extremely knowledgeable; she also has a genuine care for her patients. She takes the time to listen and what I like best is her approach - less is more! I never feel pushed into anything and she fully explains the procedure and after care. I know I am in safe hands.

A loyal client who is very lucky to find an aesthetic doctor who is professional, smart and caring. Thank you Dr Liesel.

Dr Holler has a wealth of experience and knowledge that is invaluable. I was nervous ahead of my treatment, but I was immediately put at ease. My procedure was talked through with me thoroughly and Dr Holler took the time to suggest some alternatives that would better suit me. I would absolutely recommend Dr Holler. I couldn't be happier with my results.

This is my second treatment with Dr Liesel Holler and each time she has discussed and explained things in detail with me and carefully assessed my facial profile.

My results are very natural and exactly as I wanted. It’s clear she is very skilled and knowledgeable and treats each patient uniquely. I can be quite nervous and I feel totally at ease with Dr Liesel Holler and she is the most gentle with a needle that I’ve ever experienced.

I wouldn’t trust anyone else with my face now. Thank you again!
