Congratulations on your weight loss! It's understandable to be concerned about facial sagginess after such a transformation. At 22, your skin still has a good amount of natural elasticity, but sometimes additional help is needed to address specific areas like nasolabial folds and under-eye hollows. Here are some considerations and steps you might take: Consultation with a Specialist: I recommend scheduling a consultation with a board-certified dermatologist or plastic surgeon who can assess your facial structure and provide personalized advice. Dermal Fillers: For nasolabial folds and under-eye areas, hyaluronic acid fillers like Juvederm or Restylane may be more appropriate than Radiesse, as they can offer more subtle and targeted volume restoration in these delicate areas. Number of Vials: The number of vials needed can vary depending on the extent of volume loss and your desired outcome. Typically, 1-2 vials may be sufficient for mild to moderate corrections, but a specialist can give you a more accurate estimate after an in-person evaluation. Skin Tightening Treatments: Consider non-invasive skin tightening treatments such as radiofrequency or ultrasound-based therapies, which can stimulate collagen production and improve skin firmness over time. Lifestyle and Skincare: Maintaining a healthy lifestyle with a balanced diet, adequate hydration, and a good skincare routine can support your skin's natural ability to recover and maintain elasticity. Patience with Results: Some treatments may take a few weeks to show full results, so it's important to have realistic expectations and discuss this timeline with your provider. Discussing these options with a qualified professional will help you determine the best approach for achieving a more refreshed and youthful appearance.
