Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that increased pigmentation during pregnancy is due to changes in hormonal levels in body that is causing Melasma..
The treatment that can be done is a combination of topical
depigmentation creams and certain techniques..
You can start washing your face with
Salicylic acid and
glycolic acid containing facewash..
You can apply creams containing
Kojic acid, glycolic acid and arbutin..
Vitamin E and C containing creams can help..
Creams that are rich in licorice extract and grapeseed extract can be helpful..
Always apply a SPF 50 sunscreen lotion to reduce harmful effects of UV radiations that are present in the sunlight.
You should exfoliate your skin twice a week with a gentle face scrub..
Treatments like chemical peeling, Photofacial,
Microdermabrasion, dermal rollers etc can be helpful..
Hope this information helps..
Thanks and regards.
