Can I do 1 PRP facial spaced out by a week for a total of 3 sessions in 3 weeks or would that cause problems?

Thanks for your question. By PRP facials I assume you mean microneedling with PRP. Doing this weekly is not advisable. We generally wait 4 weeks, perhaps 3 weeks would be the closest. Doing them too close together increases the risk of side effects and does not improve your result. In fact it might work against a good result by creating too much inflammation. Sometimes "too much" of a good thing, or a "too aggressive approach" with a good thing, is NOT a good thing.

PRP once every 3 weeks would not likely cause any problems, however it would be a waste. One treatment per month is the ideal regimen in my opinion.

PRP is a fabulous treatment but the ideal way to treat the area is to have the treatments spaced monthly and have 3 treatments.  You need time for the skin to heal and new collagen to form.  Best, Dr Green
