Repeating facial expressions like frowning or smiling over time creates permanent wrinkles — Botox stops the muscle movement to prevent them from getting deeper.
Scientific Claim
Repeated facial muscle contractions induce dynamic wrinkles that, over time, become fixed static lines due to collagen and elastin degradation; neuromodulators such as botulinum toxin prevent this progression by inhibiting neuromuscular transmission.
Original Statement
“So wrinkles are formed by the movement of your muscle. So if you move your eyebrows up, -There's literally like, a piece of paper and just, it gets wrinkled or like your clothes. -Yeah. Correct. So move your eyebrows up, very good. And you can see all has wrinkles. Yeah. Very good. Excellent. So. And now what happens, you have dynamic lines, so they're there when you move your eyebrows up, but you also have static lines. So I'm sitting close enough where I can see little etchings of your lines that are there. -Botox. -Yeah. So that's... so someone came to me and said, when am I ready for Botox? No one needs Botox. There's no like, correct time. But I do say when you start to see the static lines, case right here, case number one, relax, cytokines, they're there. Then you want to start doing Botox because you'll stop, you'll prevent those from becoming more deeply etched in the face.”

Evidence from Studies
Supporting (1)
This study shows that the more wrinkled someone’s forehead is from frowning, the more Botox they need to relax the muscles—supporting the idea that Botox stops wrinkles from getting worse by stopping the muscles from moving.

A 15-Year Computational Twin Modeling Study of Botulinum Toxin A Frequency and Age-Related Facial Aging.
Botox can smooth wrinkles for a while, but after 15 years, the wrinkles come back just as bad as in people who never used it — so it doesn’t stop the skin from aging permanently.
