Exosomes have become one of the most talked-about words in skin and hair care. Some clinics present them as a breakthrough that repairs everything; others dismiss them entirely. The truth sits in between, and it is worth understanding before you spend money on them.
What are exosomes?
Exosomes are tiny bubbles released by cells, far too small to see, that carry proteins, fats and genetic messages from one cell to another. They are part of how cells “talk”: a message from one cell can tell its neighbours to calm inflammation, make collagen or start repairing.
The exosomes used in clinics are prepared in a laboratory, most often from cultured cells and sometimes from plants. They contain no living cells. Because they are signalling particles rather than drugs with one fixed action, what is in a product depends heavily on how it was made, and products are not all alike.
How they are used
Exosomes are too large to soak through intact skin, so they are usually applied straight after a treatment that opens tiny channels:
- after microneedling or microneedling radiofrequency, for texture, scars and glow;
- after some lasers, to support recovery and reduce redness;
- on the scalp after microneedling, as part of a hair-fall plan.
What the research suggests
Laboratory studies show exosomes can influence the cells that make collagen and the cells around hair follicles. Small clinical studies and case series report:
- faster settling of redness and swelling after resurfacing procedures;
- improvement in texture, fine lines and glow when combined with microneedling;
- improvement in hair density in some people with pattern hair loss.
These are promising signals, not proof. Most studies are small, short and use different products, and few compare exosomes with a placebo. Regulators in several countries have cautioned against unproven claims for regenerative products, and the regulatory position of such products continues to evolve.
Who may benefit
Exosomes may be worth considering if you are already having microneedling, microneedling RF or a suitable laser and want to support recovery and results, or as one part of a hair-fall plan alongside treatments with stronger evidence, such as medicines and PRP. They are not a replacement for treating the cause of a problem, such as hormonal acne, melasma triggers or thyroid-related hair fall.
What to expect
- Some redness and mild swelling from the procedure the exosomes are paired with, usually settling within a day or two.
- Results build gradually over weeks to months.
- A course of a few sessions is common.
- Sun protection and gentle skincare afterwards.
Questions to ask before you have it
- Which product is used, where does it come from, and is it sourced through proper channels?
- What is it being combined with, and why?
- What result is realistic for my skin or scalp, and how will we measure it?
- Are there treatments with stronger evidence that I should try first or alongside?
At OrnaSkin, exosomes are used as part of a wider plan rather than on their own. Read more on our exosome therapy page, or see hair fall treatment and acne scar treatment.
