로 and 으로(after a bottom consonant, 받침, other than ㄹ) have two major meanings. 1. to, toward: an end point or destination of physical movement. 2. with, by means of: a means or way of doing something. So 입술로 can mean two things, as in these examples: 1. 그는 와인 잔을 입술로 가져갔다: He brought the wineglass to his lips. 2. 그는 메마른 입술로 말하기 시작했다: He started speaking with his dried out lips.

I'd like to point you to this http://www.learnkoreanlp.com/2008/08/particles_30.html?m=1 Are you looking up Taeyang's Eyes Nose Lips lyrics? :) 입술로 I believe means like "on the way to your lips"? (으)로 has many different meanings and I'm not great at Korean

로 -> is means. 입술로 -> by lips (입술로 말해! tell me using your lips!) 기차로 -> by train (나는 여기에 기차를 타고 왔다. I came here by a train) :)
