Any ideas?

Last night I was in the restroom and I noticed a age spot on my neck area and I've seen it before but its really noticeable now. I need to find something to blend it away. Its making me nuts because I have two lines as I know its from the sun and the interaction of antibiotics I was on. I did not realize there was a sun sensitivity and I would blister that day. So I have learned to make sure to watch what I am doing if I am ever on antibiotics again.
