Q: There are so many brands like LOreal, Shane, Lakme, Pods, Oil of Olay, etc. How to distinguish, which one is the best?

A:I do not know if there is a regulatory authority, which compares scientifically the various products in terms of efficacy and safety. If there is one, then you could approach them and find out which one is the best. Otherwise, the only way is to test each one of them on a small area of your skin and find out which one suits you the best. What is good for one person may not necessarily be so for another.
