Facial Hair, Help

Hi i am a 41 yr old female and i have been shaving my upper lip area and my chin. The upper area has a greenish or a dark color on from shaving alot, except my chin does'nt have that color. So my question is what can i use instead of shaving them..im embarrased to near people when i conversate with them, i dont like to be seen in daylight. I have a low self esteem because of it..Please help me on what should i do or use to get rid of the facial hair and dark color i have on my upper lip from shaving..
Thank u Tweet
