Can labia minora skin be elongated? can prp grow new labia skin. thank you?

PRP will not make your labia bigger. Why do you want to make your labia bigger? It is highly unlikely that making labia bigger, if it were feasible without surgery, will solve your problem. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs.
