Botulinum Toxin Injection Information
Botulinum toxin injection is a medical procedure. By regulation, it must be performed by a qualified physician using TFDA-approved preparations. Common applications include wrinkle reduction (forehead lines, glabellar lines, crow's feet) and masseter muscle adjustment. Costs are out-of-pocket. The following is a neutral compilation of public information, not medical advice.
Difference Between Dynamic and Static Wrinkles
Facial wrinkles are generally classified as dynamic or static. Dynamic wrinkles result from repeated contraction of facial muscles (e.g., when frowning or raising eyebrows), while static wrinkles are present even when the face is at rest. Botulinum toxin works by relaxing the relevant facial muscles, so it typically targets dynamic wrinkles. The approach for static wrinkles differs; suitability must be assessed by a physician.
Approved Preparations and the Concept of Dosage Units
Botulinum toxin products on the market are prescription drugs from different manufacturers, all requiring TFDA approval. Dosage is measured in 'units,' but units from different products are not directly equivalent. The dosage and injection sites are determined by the physician based on individual assessment. This site does not compare brands.
