As a cosmetic oculofacial plastic surgeon and boarded with facial cosmetic surgery, I have been doing a lot of facial procedures and I also have a lot of experience with the tear trough area. The hollowing at the tear trough area is due to skin that is very thin. There was a time in my 20 years of being practice where the treatment for the tear trough area was hard to accomplish. We used to select only a small percentage of patients to be a candidate for a permanent silicone implant. Presently, hyaluronic acid has become a very unique benefit to enhance the tear trough area. Hyaluronic acid injected alone can last for 6 months to year. However, the longevity of a hyaluronic acid when injected may be different for each patient. In our practice, we are combining hyaluronic acid fillers with platelet-rich plasma. Being very active with the regenerative medicine field, I have been using platelet-rich plasma combined with extracellular matrix for hair loss and I also use it for volume correction for acne scars. For the tear trough area, I use platelet-rich plasma because it stimulates the body’s own vascular endothelial growth factors and collagen. Platelets are cells in the blood that are necessary for healing. So we draw your blood, spin it and concentrate the platelets and the plasma that is carrying it so that we can mimic the healing response to restore quality of the skin and volume. There is a more long-term permanence to this type of procedure because it has a real improvement in the skin quality. Since you’re skin is naturally very thin and you’re only 25 years old, you don’t have as of yet, age related changes. I think that the combination of platelet-rich plasma and hyaluronic acid rather than just hyaluronic acid alone would be a good option for you. I suggest that you find a doctor that you trust and feel is not driven by a purely financial incentive. You should understand what the risks and benefits are. I hope the information about the platelet-rich plasma was helpful in your educational process. I wish you the best of luck, and thank you for your question.
