Was Sudha playing without makeup in JYOTI??

i have no idea... but i always felt she was the most beautiful among the three sisters... though she was always shown messed up while the other two sushi & jyoti were always tidy

I am sure there was makeup to make her look timid and sick.

Yep, Sudha Sharma was always w/o makeup, while Devika did wear makeup.  But once she became Sudha Vashist, she was normal in terms of dressing up
