Dark skin on back of neck, Red itchy rash on neck

Laziness has no real cure except for self motivation! However, if your son's laziness has led to him becoming fat, then you must take some measures to resolve the problem. But let us tackle the problem of the dark neck before moving to the weight issue. The neck area typically becomes black due to several reasons. It is important for you to know that this is an area with many fine folds in the skin which can sometimes not even be seen by the naked eye. This makes it very difficult to clean this particular area. Also, we generally tend to neglect scrubbing the neck too much as well, and so we manage to leave behind deposits of dirt there. This then leads to the skin becoming darker on the neck. If the neck is thick also, then there is the problem of excessive sweating, which will work towards naturally darkening that part of the body.

If you sweat too much, uric acid in perspiration will gradually start darkening the skin in the area where it is most exposed to it. In all cases, the first thing your son needs to do is to apply sunscreen before going into the sun. If nothing else, this will stop further darkening of the skin quite quickly. You can also begin exfoliating the neck once a week to ensure that dead skin from the surface comes off easily and quickly. Use any exfoliating scrub that is available over the counter. Just remember to add a few drops of lime juice to it, as this will help to lighten the skin further. For the itching, your son needs to make sure that he is washing all body parts properly and well and also drying then thoroughly. Generally, a failure to do this will lead to excessive itching. Applying rose water to the areas that itch the most will provide relief.
