Exosomes (extracted from stem cells, not your blood) are the newer premium option — early data suggests stronger effects than PRP, but research is still developing. Significantly more expensive: $1,500–$3,500/session vs. PRP at $500–$1,200. AlmaTED is a device-based ultrasound + topical serum treatment — no injections, no downtime, but earlier-stage evidence than PRP. Bottom line: PRP has the most robust research support. Exosomes show promise but cost 2–3x more. AlmaTED is gentlest but least proven. Many Orlando med spas offer all three.
