All brands put out different lines of the same product to cater to different needs- like matte eyeshadows and shimmers shadows, gel liners and liquid liners.
This new series is to help all the confused people about there who are not sure which product to buy.
I will be posting a bunch of reviews on one type of product from one brand and then I will also post a simple comparison. No this isn't a war. There is no winner at the end of the this. This is just to help you pick a product to cater to your specific needs.
Hope you find this useful...
