Avoid alcohol-containing mouthwashes, which can cause additional pain and irritation, as warned by the American Academy of Dermatology 1
Immunocompromised patients may require more aggressive and prolonged therapy, as suggested by the Infectious Diseases Society of America 4
Reconstruction of a lip that is scarred due to infantile hemangioma should be performed only after growth has definitively ceased, as recommended by the American Academy of Pediatrics 5, 6, 7
