Thank you for your question and for sharing your photos. The Russian lip technique is known for creating a more vertical lift and a heart-shaped, doll-like appearance, different from traditional lip filler styles that often emphasize volume and projection. Should You Dissolve Previous Filler First? In your case, based on the current shape and filler distribution, yes, dissolving the existing filler may be advisable before pursuing the Russian technique. Here's why: Older filler can migrate or settle unevenly over time, particularly after multiple sessions. This can obscure your natural lip shape and make it more difficult to achieve the crisp, defined results associated with the Russian lip look. The Russian technique relies on injecting into a "clean" anatomical plane. Existing filler may interfere with the precision of this technique. What Does Dissolving Involve? Hyaluronidase is the enzyme used to dissolve hyaluronic acid fillers. It's injected directly into the lips to break down the existing product. The process typically requires 1–2 sessions, depending on how much filler remains and how your body responds. You may experience swelling, bruising, or tenderness afterward, but these side effects are temporary. After full dissolving, I typically recommend waiting 2–4 weeks before re-treating the lips to allow tissue to settle and reduce inflammation. Understandably, it can feel intimidating, but many patients feel relieved once the filler is dissolved, it provides a fresh start and gives the injector more control to reshape your lips beautifully and naturally with the Russian technique.
