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 generalized
hyperpigmentation of skin and only washing face with water and soap will not be sufficient..
You will have to start topical
depigmentation treatment like washing your face with
Salicylic acid and
glycolic acid containing facewash..
You can apply creams containing Kojic acid, glycolic acid and arbutin.
You can also apply creams containing Vitamin E and C and also azaelic acid preparations.
You can also exfoliate your skin twice a week..
You can also apply sunscreen lotion whenever you are exposed to sun..
You should take Vitamin C supplements..
You should drink plenty of water..
You can also go for treatments like
Microdermabrasion and chemical peeling..
Hope this information helps..
Thanks and regards.
