Why do my facial features looks so different in tiktok camera?

I mean, comparing with pictures taken with my phone normally and pictures using tiktok i look way too different (better) i don't mean thing like skin softness or color and stuff like that (all kind of filters are deactivated) For example, my lips are uneven, and with my normal camera this is very noticeable but in the tt camera that almost disappears, obviously both pictures are taken in the same spot, angle and light.
