I was very obese for many years, which meant I had a double/triple chin. This has caused fold lines in my neck and they are all very dark. I have now lost a lot of weight and in very good shape but those dark lines haven't gone. I have a lighter skin and these dark neck lines stand out, making me feel very conscious and less confident. I have also developed a few skin tags along those neck lines. I tried different creams and homemade skin bleach solutions but nothing worked. Any help or advice on what I can do to get rid of that dark skin/lines please?
