Thanks for your query.
Your face and neck is darker than rest of the body that is the sun exposed parts indicates that you have sun tan. It seems you have significant sun exposure or your skin is sensitive to sun. You have uneven tone and black spots.
Don't be tensed.
You may do as follows:
-Avoid sun exposure as much as possible especially from 11am to 3pm when sun rays are most damaging.
-Use a sunscreen during the day even if indoors and repeat every 3-4 hours.
-Use a hydroquinone
, momatosone cream on the black spots at night under dermatologist's supervision for 1-2 months then shift to milder cream like kojic acid
based for maintainance.
-Take a diet rich in fruits and green vegetables.
-Take oral beta carotene
, Vitamin C
-drink plenty of water say 2-3 litres per day.
You have got chemical peeling done which will actually takes care of all your concerns ,black spots, sun tan, uneven tone. You require multiple sessions of it spaced 15-20 days.
It does increase sensitivity to sun but that can be taken care by avoiding sun exposure as much as possible and liberal use of sun screen during the day.
Hope this helps you.
