Dear Hello, Welcome to Healthcaremagic!
You have not mentioned why you are not satisfied with your natural dusky complexion; also you want a fairer complexion of face only?
I sincerely advice you against beauty parlours.
For face, you can start using glycolic acid
6% cream (available in India as Glyco 6% cream), to be applied on face at NIGHT only. In day time use a good quality sunscreen. Please let me know the results in say 1-1 1/2 months.
