It is possible to use neurotoxins, also known as neuromuscular toxins, to prevent wrinkles from forming due to repetitive muscle movements, and to smooth wrinkles that may appear as a result of natural aging. Neurotoxins relax muscles that cause wrinkles and lines on the face. By ensuring consistent neurotoxin touch-ups and follow-ups every 3-6 months, less neurotoxin may be required each time.
