Can Lip fillers move to the inside of mouth? (Photos)

I understand your concern. I've been injecting fillers for almost 20 years and I don't think I've ever seen a product migrate to another area. Usually massage with soften lumps and bumps and smooth them out but I've never seen filler pushed into a different area. Sometimes, the product isn't injected at the correct depth and that can lead to the issues you're facing. I would return to your injector and have the product dissolved with hyaluronidase but this will only work on hyaluronic acid based fillers.
As with all cosmetic procedures, especially when it comes to fillers, the skill of the injector is paramount. Always seek an expert in facial aesthetics, such as a board-certified dermatologist, to maximize results while minimizing side effects.

Thank you for
your question chelseacaarrxx. I understand your concern. Fillers are used to
restore lost volume in and enhance the appearance of the face. They are commonly used in the lips. Sometimes the product migrates slightly. This occurs more when it is massaged, which is why I discourage my patients from massaging themselves. However hyaluronic acid fillers can be dissolved if the product migrates to an unintended site. Please
consult with a doctor for specific recommendations.  Good luck!
