Long-term botulinum toxin injection may produce drug resistance, muscle atrophy and other hazards.
1. Produce drug resistance: There are many products related to botulinum toxin, which are widely used in the field of micropigmentation, such as face-slimming injection, leg-slimming injection, shoulder-slimming injection and so on. The principle of action is to inject botulinum toxin into the corresponding parts of the muscle, through blocking the nutritional effect of the nerve on the muscle, so that the muscle gradually atrophy, to achieve the corresponding effect.
If injected frequently, when Botox reacts with antigens and antibodies in the muscles, the muscles will become resistant to Botox due to the long-term injection of too much Botox.
2. Muscle atrophy: Because botulinum toxin will reduce the innervation of the nerve to the muscle, the muscle will gradually atrophy, but after a period of time the muscle will slowly restore the innervation of the nerve. Therefore, the interval between injections should be more than three months.
If injected frequently, the innervation of the nerve to the muscle will be weakened, and the muscle will gradually atrophy, resulting in calf or facial expression muscle weakness, unable to make expressions and other corresponding harm.
Therefore, patients should follow the medical advice to inject Botox to avoid causing adverse consequences.
