Firstly one should always try to achieve his or her constitutive skin colour. It is not at all possible to become fair or white from wheatish or light brown skin complexion. Instead aim for a healthy ,flawless ,glowing skin tone. The film actress quoted by you is still considered to be of dusky complexion rather than being fair. However I will suggest certain things that might help you with your query
Follow a daily skin care
routine of cleansing, toning and moisturising twice in a day( skip toners in winters) with products best suited to your skin type
Use sunscreens daily and avoid sun exposure as much as possible
Take vitamin c
and antioxidant supplements for few weeks
Use glyco a cream morning and skin lite cream night over face for three weeks(do not use beyond three weeks as might harm your skin). If in case redness
or burning occurs with either of these creams stop their application completely.
You might also consider taking peels from a dermatologist
for further glow and improvement of skin tone.
Follow the above mentioned advise for the stipulated period of time and get back to us. Take care.
