How botox works:
Repeated muscle contractions from frowning, squinting, or raising eyebrows cause skin to furrow and fold, gradually resulting in the formation of facial lines. BOTOX Cosmetic works beneath the surface and temporarily reduces the underlying muscle activity that causes moderate to severe frown lines, crow’s feet and forehead lines in adults – to help them look better.
What to expect with the treatment:
Some patients receiving BOTOX Cosmetic report the injections feel like a pinch. You may begin to notice a visible smoothing of frown lines, crow’s feet and forehead lines within 24 to 48 hours, with full results in 30 days lasting up to 4 months for moderate to severe frown lines.
BOTOX Cosmetic is not a permanent treatment. If you discontinue treatment the moderate to severe frown lines, crow's feet and forehead lines will gradually return.
