Is PRP therapy ineffective?

I doubted the effectiveness of PRP therapy for cosmetic purposes.
Since it is not cost effective, it is no longer done in the beauty field.

This research does not specify what the PRP production kit used.

PRP kits may not be effective at all.

We have been carrying out PRP therapy for cosmetic purposes in our hospital, but fine wrinkle improvement by injection into the lower eyelid and skin firmness have been obtained in most cases. Therefore, we must say that it is wrong to conclude with this.

However, at present, in clinical cases, I doubt that there is no effect, but there are many other good treatments, so I think that there is almost no cosmetic need anymore.

The effectiveness in the sports field is tremendous. I think there is no room for doubt about the effectiveness of PRP therapy in the sports field.
