It's not proxima, look closely

Maybe? But the thing is, I think the TikTok comments font in YOUR picture is a copy of another font with slight tweaks. So I don't think you're gonna get anything better than this. The font for TikTok comments on me is Proxima Nova, desktop and mobile app (hence why I added "in YOUR picture").

Is it an old picture? If so, how old?

Never mind that can't be right, it can't be an old picture now that I look at it. But still, why is yours different? On my app the font is indefinitely Proxima Nova, but on yours, for some reason, it's not Proxima Nova.

Anyway, check out the font I newly suggested, it's probably the closest you'll ever find, as your apps font is probably a custom font based off of another. Sole Sans Book I think is the closest you'll find

You could also check out the other Arial fonts in the Arial font family, could potentially be the font you're looking for, they look very very similar.

I apologize if I'm being forceful. I forgot to say that this isn't my picture. I got it from Facebook and I am aware that Proxima is the default font for TikTok. But this one's different so I had to post this ASAP.
