What's your favourite brand of makeup and skin care

One question ???

I am quite sure about this app, it's been third day of mine here but still I am not quite sure about it and one last thing I will like to ask that why , what makes you to install this app

What is this app for ?

I am really interesting knowing that is there any make up product which is combined with skin care products like any concealer with moisturizer , or stuff like that ???

Do you have a idea?

Does buying cheap skin care means it will not work properly , and buying expensive skin care means it works ? Is there any differences
