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 you need to take
depigmentation topical treatment along with certain chair side treatments at the dermatologist's office for relief..
You can start washing your face with
Salicylic acid and
glycolic acid containing facewash..
You can start applying creams containing Kojic acid, glycolic acid and arbutin..
You can also apply Vitamin E and C containing creams..
You can also take Vitamin C supplements..
You can apply azelic acid creams..
Grapeseed extract and licorice extract containing creams are also helpful..
You can exfoliate your skin twice a week..
You can also limit sun exposure and always apply sunscreen lotion when exposed to sun..
You can also go for treatments like
Microdermabrasion, chemical peeling and photofacial..
Drink plenty of water and take more of green leafy vegetables and fruits in diet..
Hope this information helps..
Thanks and regards.
Dr.Honey Nandwani Arora.
