Is it true for already protruding lips based on just bone structure, it is better not the get lip fillers?

Hi I have a producing lips one doctor told me and it is better not to get lip fillers is that true? I get lip fillers just to make my lips look longer and wider since I have bigger nose and I found lip fillers make my nose look smaller but the problem is I found out that because I have natural protruding lips but very thin lips, it is better not to have it? Thank you
