Does stem cell microneedling actually use stem cells?
No. The serum is made from what lab-grown stem cells release, usually growth factors and exosomes. The cells themselves are not in the bottle and none end up in your skin.
Microneedling with stem cells does not put living stem cells into your skin. The serum is made from what lab-grown cells release, and it is spread on skin that has just been needled. PRP uses your own blood, spun to concentrate the platelets, and it goes on the same way. The needling is the part with real evidence behind it, and what goes on top is the part still being argued about.
| The difference | Stem cell microneedling | PRP microneedling |
|---|---|---|
| What is actually applied | Growth factors or exosomes in a fluid | Your platelets and the plasma around them |
| What does the work | The needling, plus a signalling serum | The needling, plus your platelets |
| What it is used for | Texture, dullness, scars, thinning hair | Acne scars, texture, thinning hair |
| What the evidence looks like | Early and small | Larger, and still mixed |
| Cost | The more expensive add-on | The cheaper add-on, and a course |
Side by side
Stem cell microneedling
A cell line grown in a laboratory
Usually fat-derived or umbilical cells. The cells are grown, then what they release is collected, filtered and bottled.
PRP microneedling
Your own blood, drawn that day
A tube is taken, spun in a centrifuge, and the platelet-rich layer is separated from the red cells.
Stem cell microneedling
Growth factors or exosomes in a fluid
No living cells go in. What goes in is the signalling material the cells produced.
PRP microneedling
Your platelets and the plasma around them
Platelets carry their own growth factors, which is the reason for using them.
Stem cell microneedling
The needling, plus a signalling serum
Thousands of tiny channels are made first. The serum is meant to travel down them.
PRP microneedling
The needling, plus your platelets
Same channels, same idea, different material going into them.
Stem cell microneedling
Texture, dullness, scars, thinning hair
Sold for much the same list as PRP, and often marketed as the stronger version.
PRP microneedling
Acne scars, texture, thinning hair
Sunken acne scars and scalp thinning are the two biggest uses.
Stem cell microneedling
Two to three months
Collagen builds slowly, whichever serum is used.
PRP microneedling
Two to three months
Usually a course of three to six sessions about a month apart.
Stem cell microneedling
Not measured beyond six months
Published follow-up stops early, so nobody can say what happens at a year.
PRP microneedling
Fades without maintenance
Most clinics offer a top-up session every six to twelve months.
Stem cell microneedling
Early and small
A review of the published studies found signs of benefit for ageing, scars, pigment and hair, from small studies with short follow-up. The authors called for larger trials before drawing conclusions.
PRP microneedling
Larger, and still mixed
The clearest finding is that adding platelets to needling helps acne scars somewhat. Some comparisons put needling with a chemical peel ahead of needling with platelets.
Stem cell microneedling
Where the serum came from
No exosome product is approved for injection or infusion in the United States, and quality depends entirely on the supplier. There is no ingredient list you can check.
PRP microneedling
Where the blood is handled
Blood is drawn, spun and put back into open channels. That belongs in a licensed facility with single-use equipment.
Stem cell microneedling
The more expensive add-on
The serum is bought in by the clinic and priced per vial.
PRP microneedling
The cheaper add-on, and a course
Ask what the whole course costs, including the needling itself.
Stem cell microneedling
Retail serums are a different thing
They sit on intact skin. A 0.25 mm home roller does not open the channels a clinic pen makes, so nothing goes deeper than a normal serum.
PRP microneedling
There is none
Nothing sold over the counter can draw and spin your blood.
Stem cell microneedling
PRP microneedling
Stem cell microneedling
No stem cells stay in your skin. The cells are grown in a laboratory, and what is harvested is the fluid they were living in, or the exosomes filtered out of it. The cells themselves are not in the bottle.
Common questions
No. The serum is made from what lab-grown stem cells release, usually growth factors and exosomes. The cells themselves are not in the bottle and none end up in your skin.
There is no clear answer. The published studies on exosomes with microneedling are small and short, while PRP has a larger but still mixed record.
They are tiny packets that cells release to send signals to other cells. They carry proteins and genetic material that can influence collagen production and inflammation.
No exosome product is approved for injection or infusion in the United States. That means quality depends entirely on the supplier the clinic buys from.
Both usually run as a course of three to six microneedling sessions about a month apart, with results building over two to three months.
No. Retail serums sit on intact skin, and a short home roller does not open the channels a clinic microneedling pen makes.
No. The FDA has not authorized microneedling devices to deliver PRP, cosmetics or drugs into the skin. There are also no FDA-approved exosome products. Ask exactly what is being applied and what evidence supports that combination.
