Thank you for sharing your picture. The tear trough is a tricky area to fill. Because of the thinness of the skin, there is a higher risk for undesired lumps and bumps and depending on the filler chosen there may be a slight blue tinge. Of course, if you get injected with a hyaluronic acid filler and you do not like it, it can be dissolved. PRP or PRF can be a safe option to treat this area. The product comes from you. There is no risk of lumps or bumps. Injecting and microneedling PRP or PRF can help with firming the skin and improving tone or texture in this fragile area. Typically more than one session is required. There may be a need for filler later. However, if filler is needed later, the amount of filler required should be less. When things do not go as desired around the eye, it can be very challenging for all involved. Yes, I think you should strongly consider trying PRF first. This is not an area to have cost alone make the decision for you.
