The problem with both fat transfer & autologous stem cell therapy is that the results are less predictable than dermal fillers. Undoubtedly the current state of knowledge yields much better results compared to when I first did fat transfer 12 years ago. The fact remains that even with meticulous processing, fat resorption rates of up to 65% can be seen. Additionally there have been a paucity of good studies beyond 1-2 years in the context of longevity.

Regardless of resorption rates, stem cell & adipose tissue transplantation still has a role in the management of moderate to severe atrophic scars. The reasoning behind this is that in some patients the volume of filler may exceed over 15 MLS. Costs play a big factor in the management of clinically significant atrophic scars

It is important to understand that scar revision largely relies on your own immune system to remodel scar tissue. If you can not remodel tissue, procedures like stem cell & adipose tissue can assist your immune system to repair scars. In those people who struggle with tissue remodelling, the only viable option is dermal fillers.

Everyone wants a permanent solution, including dermatologist & plastic surgeons. Our aim is to treat scars & then discharge patients. The fact remains that your results are largely reliant on your immune status. This can not be controlled by physicians.

What is PRP & is it the same as stem cell therapy?

PRP is a super easy procedure of taking your own blood, spinning it down (less than 10 minutes) then either sprinkling the solution on the wounds left from microneedling (or laser). In some cases, it is injected into your skin. The role of PRP is controversial. PRP has better evidence in the context of hair growth & joint therapy.

PRP does not contain stem cells, as it stands for platelet-rich plasma. PRP contains growth factors derived from platelets with a typical hyper-concentration of between 4.5 to 6.0 X.

I do not routinely offer PRP as I believe that it has only marginal effects on healing times & no added benefit in the context of revision of atrophy. I do believe that fat transfer gives better & more predictable results than PRP. I also know of the case reports of adding PRP to fat grafts for˜boosted results. Once again the level of good evidence for this technique is lacking.

If you feel inclined to opt for PRP with stems, let me know, as I do not routinely perform this procedure nowadays. (I used PRP for nearly every case of scar revision from 2014 to 2016 with the under and over technique. I do believe that heal is ever so slightly faster with PRP but the end results are not superior. Happy to discuss.)
