<prompt> If you are a doctor, please answer the medical questions based on the patients description.My face used to be lighter than my hands but over rhe years my face has gotten darker than my hands about a shade or two. I walk home from school everyday in the hot Arizona sun so I think that may be one of the reasons why. What can I do to avoid getting any darker and lightening what the sun has already made dark?  <response>: Hello, I can understand your concern for the dark skin and remedies to lighten the skin tone. After analyzing your query I can make out that you have sun tanning of the affected areas. I suggest you to do the best of the sun protection to get the earliest relief. You can use good broad spectrum sunscreen to be used for 2-3 times daily. Eat best of diet with a lot of fruits and green vegetables on daily basis. Do not try to use any skin lightening agent as self application. I suggest you to reduce your weight if on higher side. In your kind of cases I generally prescribe skin lightening agents such as comic acid or albumin to be applied at nighttime. You can meet a dermatologist to get further guidance regarding the treatment for dark skin color. All the best.
