Would Plasma Fibroblast work for monolids? Not looking for a dramatic difference.

I (28F) have monolids. 1 eye has a very small 'double lid' crease but the right doesn't at all. Sometimes does with tape, but scared it will sag in the long run. Questions: 1. Would PRP work to create that subtle double eyelid? 2. Are there other non-invasive options? 3. I'm scared that PRP can cause more damage than good. Why is that it works for some but not others? Is it the pen they use? wrong technique? What questions should I ask when looking for someone who does it?
