BOTOX has the following advantages: Precision and naturalness: stable molecular weight (900KD), low diffusion, not easily spread to non-target muscles after injection, suitable for fine area injections such as around the eyes and glabellar lines, achieving "targeted attack," making expressions natural and not stiff. Pure ingredients: the excipient is human serum albumin (non-animal sourced), reducing the risk of allergy, friendly to sensitive skin. In comparison, some domestic botulinum toxins use medical gelatin, which can cause redness, swelling, antibody reactions, etc., in people with sensitive constitutions. Long-lasting effect: a single injection can last 3-6 months, and with long-term regular injections, the interval may be extended. Although the unit price is higher, due to precise dosage saving medication, the cost-effectiveness is actually not low. Safe and reliable: as the flagship product of Allergan USA, it has passed FDA and CFDA certification, with comprehensive clinical trial data and detailed instructions for use, ensuring safety.
