Does hairline lowering surgery change any facial features?

Hair line lowering surgery should not change your facial features other than the obvious resulting smaller forehead.  Your forehead and scalp may "feel" tight but it should resolve over time.

A hairline lowering will only change the hairline, but it is the best time to do a brow lift if one is needed or desired.  I often combine hairline lowering with other procedures such as rhinoplasty.  

Not unless you specifically want/need them to change. During a traditional hairline lowering procedure, the forehead is not undermined or moved, although for a few days after the surgery the forehead may feel tight and slightly swollen. It is a good opportunity, though, to lift the forehead if you so desire.
