While Lip Blushing is a semi-permanent cosmetic tattoo treatment that is generally a safe procedure, individuals with a history of cold sores or herpes simplex virus (HSV) should refrain from lip blushing as the procedure may trigger a recurrence of the virus.  Lip Blushing can also makes it challenging to detect early signs of cold sores, potentially delaying treatment. Pregnant or breastfeeding women should also avoid lip blushing due to unknown effects the treatment may impose on babies. If you have a specific medical condition, such as blood clotting disorder, please consult a medical professional to determine the safety of lip blushing. Anyone allergic to the ink or other ingredients used in the procedure should refrain from lip blushing. Conducting a patch test prior to any cosmetic procedure is crucial to identify potential allergies.
