Microneedling is a reasonable stretch-mark option, and published comparison work reports better aesthetic improvement when it is combined with a partner protocol. A small randomized comparative study of 30 patients — 28 with stretch marks and 2 with post-surgical scars — compared microneedling alone with microneedling plus autologous platelet-rich plasma, a preparation made from the person's own blood, and reported higher aesthetic improvement or satisfaction in the combination arm Comparative study of microneedling monotherapy versus microneedling with autologous platelet-rich plasma for the treatment of stretch marks (striae distensae) and post-surgical scars.
What did the study compare?
It compared microneedling alone with microneedling combined with autologous platelet-rich plasma. The cohort was mixed: 30 patients in total, of whom 28 had stretch marks and 2 had post-surgical scars Comparative study of microneedling monotherapy versus microneedling with autologous platelet-rich plasma. The comparison is the design, and the mixed cohort is the detail worth noticing before any number is read.
What did the combination arm show?
The combination arm was reported to have higher aesthetic improvement or satisfaction across the pooled cohort outcomes. The study reported the difference in aesthetic improvement or satisfaction rather than in a single instrument, and the finding favours the combination over needling alone. Because the outcome was judged on appearance as well as on dermoscopy, the reported advantage is about how the treated areas looked rather than about a laboratory measurement.
What does the mixed cohort mean for you?
It means the reported advantage applies to the whole studied group, so read it as support for the combination rather than as a stretch-mark-specific figure. With 2 of the 30 patients having post-surgical scars, the published comparison covers everyone together, and the combination is the practical unit to plan around.
The reported credit belongs to the full combination the study used. Splitting it between the two components would be a claim the study was not designed to make, and the combination is also the part you can plan around.
How should you plan stretch-mark work?
Plan it as a combination rather than needling alone, and judge it over a course. Documented equipment facts cover the microneedling component only: device identity, cartridge models and interface compatibility, without claiming the combination outcome for any device. A plan that treats the partner protocol as optional is a plan the study did not test.
PRF and PRP for abdominal stretch marks covers the related combination work, contraindications covers who should not have the procedure, and reported reactions covers what to expect after a session.
Frequently asked questions
Does this study prove microneedling with PRP treats stretch marks?
It shows the combination outperforming needling alone in one small mixed cohort, which is support rather than proof. The group included post-surgical scars as well as stretch marks.
Does the finding apply specifically to stretch marks?
No. The cohort mixed 28 people with stretch marks and 2 with post-surgical scars. Treat it as support for the combination across those scar types rather than a stretch-mark-only figure.
Does microneedling alone work for stretch marks?
The reported advantage was in the combination arm, not in needling alone. The study compared needling alone with needling plus platelet-rich plasma, and the difference favoured the combination.
How long before I judge the result?
Judge it over a course rather than after one session. The literature describes improvement that builds across repeated treatments.
Plan the combination for stretch marks
The comparison points to a combination rather than needling alone. Read PRF and PRP for abdominal stretch marks for the related work, then contraindications before you commit to anything.
