First thing’s first,to be good at using something,you need to understand what it is.So ….what’s the purpose of blush?
Blush is to add colour into your face after you have smoothed all the imperfections.It makes your cheeks more rosy and more defined.
Blush belongs on the apple of your cheeks.It should look like the sun bent over and kissed you.
You go for rosy, not red.
