While there is no known interaction between minocycline and lip fillers, it is important to consult with a healthcare professional before undergoing any cosmetic procedure while taking medication. It is especially important to inform your healthcare provider if you have any history of allergies, hypersensitivity, or adverse reactions to medications, as this may affect your eligibility for lip filler injections. In general, it is always recommended to disclose all medications, supplements, and medical conditions to your healthcare provider prior to any cosmetic procedure to ensure your safety and optimal treatment outcomes. It is also important to choose a reputable and qualified provider who follows proper safety protocols and uses only FDA-approved fillers. Your provider should be able to answer any questions you may have regarding the procedure and discuss the risks and benefits associated with lip fillers. Best of luck !
