Hi
Thanks for your query
You seem to have developed skin pigmentation due to tanning.
Topical medications can definitely be of help to you in reducing the pigmentation to some extent.
I would advice that you should use a lightening agent like
kojic acid and
vitamin c combination over the affected areas. This is a simple, harmless lightening agent which can be used for as long the blackish pigmentation is there.
Also ,try not to touch the area too much
Use proper sunscreen (spf>26) before going out in the sun so that the lesion doesn't darken any further
Take a diet rich in vitamin C and antioxidants like Citrus fruits and lots of salads
If after all the above measures, the pigmentation tend to persist, then i would advise that you should see a
dermatologist as there are various other measures for the treatment of pigmented skin like the use of
chemical peels,
dermabrasion etc which a dermatologist can decide according to the type of scars..
Hope it helps
Wishing you speedy recovery
