Will my facial line change if I do face yoga?

While searching for skin-related videos on YouTube, the algorithm showed a lot of face yoga videos. I was tempted by the before-and-after photos of YouTubers and have been following along for a while, but I haven't noticed any changes in my facial line yet. Haha. But since I usually live with a blank expression, I feel like my facial muscles are starting to relax a bit. Even if it's not possible to see a change in my facial line, if I keep doing it, it will help prevent my skin from sagging, right?
