I. Dose and drug proliferation control
Precision dose: the effects of injectable drugs such as meat toxin are directly related to the dose. The appropriate injection only weakens the contraction of the target muscle and preserves the natural expression; excess may lead to excessive muscle relaxation, disharmony and rigidity. 1. Drug characteristics: dispersive radiuss (diffusion ranges) vary from drug to drug. For example, the low dispersibility of certain drugs, suitable for fine areas (e. G., eye wrinkles), reduces the influence on the surrounding muscles. 2.
Ii. Doctor's technical and anatomy knowledge
Injecting depths differ from levels: injections of muscles, subcutaneous or real cortex have different effects. Experienced doctors are able to pinpoint target muscles and avoid drug proliferation to unrelated areas. 1. Structural differences in anatomy: there are individual differences in the distribution of muscles and neuropaths among individuals. Doctors are required to adapt their programmes to face dynamics (e. G. Smiles, frown habits) to avoid influencing face-to-face contact. 2.
Iii. Effects of individual physiological conditions
Muscular strength and metabolic capacity: muscular developed people may need higher doses to be effective, but overdose can lead to rigidity; rapidly metabolic human drugs are short-lived and have relatively high tolerance for errors. 1. Skin elasticity and fat thickness: for people with tight skin or thin fat layers, drug proliferation is more likely to be limited and the risk of expression rigidity is reduced. 2.
Iv. Post-operative care and adaptability
Avoiding local irritation: post-injection massage, high-temperature environments or intense motion can accelerate drug proliferation and increase the probability of rigidity. 1. Neuro-adaptability: some people may have a slight rigidity in the short term, but the nerve gradually adapts to muscle relaxing, and after two to four weeks the expression becomes natural. 2.
Selection of reasonable treatment targets
In the pursuit of natural effects, priority is given to the injection of dynamic (wrinkles in expression) rather than to the total elimination of static textures. Maintaining part of the muscle activity reduces the risk of masked face。
Summary
The rigidity of the facial injection is essentially a balance between control of the extent of the drug's effects and muscle compatibility. Through individualized programme design, precision operations and post-operative management, most people achieve natural effects. In case of rigidity, the drug metabolism usually recovers after several months, without undue concern。
