Thanks for writing in.
Skin lightening cream contains 2% hydroquinone
and a very potent steroid mometasone
This ingredients can cause permanent depigmentation
of skin leading to white spot.
It is not advisable to use it for long time.
My advise to you would be -
Stop using steroid based creams.
Use a good sunscreen during day time.
You can apply a cream called kozimax cream at night over dark spots.
it is safe and effective.
Fairness will come back but process is slow may take 2-3 months of treatment.
Take a lot of Vit C in diet.
Color will come back but process is slow may take 2-3 months of treatment.
Avoid any HQ and steroid based creams in future.
Hope this helps.
I will be available for follow up.
