The early proliferation period is 1-2 months after birth, and by 3 months after birth, the growth of hemangioma generally reaches 80% of the final tumor, so 3 months after birth is the critical period for hemangioma treatment (early treatment to avoid tumor enlargement, which requires more effective treatment, and even after enlargement, it is easy to leave aesthetic problems, such as skin laxity, scarring, and fibrofatty tissue redundancy). (and fibrofatty tissue redundancy). In the past, it was thought that hemangiomas did not need treatment and should wait for natural regression, but after natural regression of hemangiomas, local erythema, pigmentation, vascular dilatation, local skin laxity, scarring and fibrofatty tissue redundancy are often left behind, affecting aesthetics (especially on the face). With the advancement of medical technology, the existing treatment methods are fully capable of changing the natural course of hemangioma (such as controlling the proliferation and promoting the regression of hemangioma) to achieve the most perfect results as possible and in a safe manner. The current treatment methods are also safe and effective. For example, they can be treated by topical topical medications (e.g., receptor blockers, glucocorticoids, imiquimod, etc.), pulsed dye lasers, and, for high-risk hemangiomas, oral insulin.
