Would Platelet Rich Fibrin injections be a good option for laxity around my eyes, mid face and nasolabial folds? (Photo)

I'm not quite sure why you have not considered the option of treatment with a robust HA Filler. In experienced hands, using an appropriately robust HA filler and injected with the proper technique for cheek augmentation, the prominent under eye tear trough can be significantly improved, the cheek volumized and the prominent smile lines diminished. The treatment in experienced hands should take no more than ten minutes to perform and the results typically immediately seen with a "Wow!" response. And, with the right filler can last up to 1.5 years. So, I am not quite sure how PRF (or PRP, for that matter) would be preferable, especially considering that several expensive treatment one-hour long sessions would be typically required and even more importantly the hard science to support these treatments lags woefully behind the heavy marketing hype to promote their use. Make sure to consult a board certified, experienced injector cosmetic dermatologist. Best of luck.
