Thanks for writing in.
Skinlite contains mometasone
a very potent steroid.If used for longer time it may damage your skin.
You can shift to safer options like kojic acid
in KOJIGLO gel.
Photoprotection is a must for any pigmentation problem.
Avoid sunlight .Use hats/caps/scarf etc.
Take a lot of lemon juice daily.Also you can take vitamin C
You should use a good quality sunscreen like Shadows 50.twice or thrice daily.
I encourage you to visit a qualified dermatologist
for proper diagnosis and treatment.
Hope this helps.
