Hi..
Welcome to HEALTHCARE MAGIC..
As per your query as you have a sensitive skin that gets tanned when exposed to sun you should apply a SPF 50 containing moisturiser when exposed to sun.
Keep your face covered as much as possible to prevent sun exposure and darkening..
You should avoid all kinds of chemical containing face cosmetics as for dryness
aloevera gel is the best product that can be applied on face as it also has antibacterial, antifungal and skin nourishing properties..
You can also apply a cooled aloevera gel by cooling it into refrigerator..
If you want to lighten skin colour you can use
kojic acid containing creams,
vitamin C supplements,
glycolic acid and arbutin containing creams..
Vitamin E oil and capsules are also very helpful for getting a smooth, shiny and healthy skin..
Exfoliate your skin once a week using a mild scrub and massage after scrubbing using a dermatologically tested massage cream.
Drink plenty of water, take vitamin supplements and keep your weight under control..
Hope this information helps..
Thanks and regards..
