Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that you have got
Hyperpigmentation of skin due to sun exposure..
As your skin is sensitive to sun you can always cover your face with scarf when exposed to sun..
You can limit sun exposure as much as possible..
As of now you can start washing your face with
Salicylic acid and
glycolic acid containing facewash..
You can apply
Kojic Acid containing creams as it is Mushroom extract and safe for long term use..
Creams containing Vitamin E and C as well as Arbutin are effective..
You can scrub your face twice a week with a gentle scrub..
You can take steam exposure on face and then gently scrub with a soft towel to remove dead skin..
You can always apply sunscreen lotion when exposed to sun..
You can also go for a treatment like
Microdermabrasion and chemical peeling..
Hope this information helps..
Thanks and regards.
