Possible Reasons for Rapid Filler Dissolution:
* Your Metabolism: While metabolism does play a role, it's unlikely to dissolve filler *this* quickly. Very high metabolism is more likely to cause filler to last shorter (e.g., 3-6 months instead of 6-12), not disappear in a week.
* Product Type: Some fillers are naturally thinner and more easily broken down (e.g., Juvederm Volbella). However, even Volbella shouldn't dissolve this rapidly.
* Injection Technique: If the filler is injected too superficially, it's more susceptible to breakdown and migration. Also if the filler is not injected to the right layers of the lip.
* Enzyme Activity: Hyaluronic acid fillers are broken down by the enzyme hyaluronidase. It's extremely unlikely, but theoretically, if you had unusually high hyaluronidase activity in your lips, it *could* contribute to faster breakdown.
* Inflammation/Infection (Rare): Significant inflammation or a mild infection could theoretically speed up the breakdown process. But you'd likely see other symptoms too (redness, swelling, pain, heat).
* Product Quality/Authenticity (Very Important): This is a major concern. You need to make sure the filler being used is an authentic, FDA-approved product. Counterfeit fillers are a real problem and could contain substances that are quickly absorbed or broken down.
* Perception vs. Reality: It's possible that what you *think* is the filler disappearing is actually the initial swelling going down. The immediate post-injection volume is often due to swelling, which resolves quickly, leaving behind the actual filler volume.
* Filler amount injected: A very small amount of filler (less than 0.5 ml) may not be noticeable for very long.
* You're unknowingly causing it: Some medications can cause the filler to dissolve faster (like steroids).
What You Should Do Immediately:
1. Contact Your Injector: This is the most important step. Schedule an appointment to discuss what's happening. They can:
* Examine your lips to assess the situation.
* Review the type of filler used, the amount injected, and their injection technique.
* Inquire about your medical history and any medications you're taking.
* Help determine the most likely cause.
2. Verify Product Authenticity: Ask your injector for the packaging and product information (batch number, expiration date). You can contact the manufacturer (e.g., Allergan for Juvederm, Galderma for Restylane) to verify the product's authenticity.
3. Track Changes: Take clear, well-lit photos of your lips immediately after the injection and every day afterward. This will help you and your injector track the changes and better understand the timeline of the filler's disappearance.
4. Consider a Different Injector (If Necessary): If you're not satisfied with your injector's explanation or if you suspect they're not using authentic products, seek a second opinion from a highly qualified and experienced injector. Look for board-certified dermatologists or plastic surgeons who specialize in injectables.
5. Be Cautious About Further Injections: Don't get more filler until you understand why the previous injections dissolved so quickly. Adding more filler without addressing the underlying problem is unlikely to be a long-term solution.
6. Avoid Sunbeds and excessive sun exposure: UV light can degrade fillers more quickly
Important Considerations:
* Filler Longevity is Variable: While most fillers last 6-12 months, individual results can vary depending on the factors mentioned above.
* Realistic Expectations: Lip filler results are subtle for some. Discuss your desired outcome with your injector to ensure your expectations are realistic.
In summary, filler dissolving in a week is not normal. It's crucial to investigate the cause with your injector and take steps to ensure you're receiving authentic products and appropriate treatment.
