A combination of factors can cause facial lines. It’s not just about the cellular changes that may occur, or reduction of collagen, or damage caused by free radicals from the sun and the environment.
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 is a quick 10-minute treatment that 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.
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 results 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.
