Thank you for sharing your concerns so clearly. After weight loss, it’s common for the midface to lose volume, making the cheeks appear flatter and the midface longer or narrower. The approach depends on the degree of volume loss and the effect you want to achieve. Cheek Fillers: For many patients in their early twenties, dermal fillers are an excellent first option. They are minimally invasive, provide immediate results, and can lift the midface to restore a rounder, more youthful contour. Hyaluronic acid fillers like Juvederm or Restylane are commonly used, and the results typically last 12–18 months depending on the product and individual metabolism. Fillers are often the most cost-effective way to address midface volume loss without surgery. Other Options: If you’re looking for longer-term results, fat grafting (also called microfat or autologous fat transfer) can restore volume permanently by using your own fat. This is more expensive upfront and involves a minor surgical procedure, but it can provide natural, lasting results. Key Considerations: Fillers allow you to see changes gradually and adjust as needed, which can be ideal for someone young. Cheek fillers can also subtly lift your midface and improve facial proportions, helping the face appear shorter and fuller without overfilling. The best approach often combines volume restoration with careful contouring, rather than just adding filler in one area. Overall, for your age and desire for cost-effectiveness, cheek fillers are likely the best starting point, and you can always reassess in the future if more permanent solutions are desired. Your midface can absolutely regain a youthful, lifted appearance, and a personalized consultation can help map out exactly how much and where to place filler for a natural result.
