I'm a fashion model who uses them frequently. No matter what kind of make up it leaves my face fresh and clear. However, I will stress the importance of hygiene. Regardless if you use these whips you should still follow up with a facial cleanser and or moisturizer if needed. I've witness too many people who will use the neutrogena whips and not take care of their skin then blame the product.
I love my sephora brush set. It is very important to continually clean your makeup brushes. Not doing so , can lead to severe skin irritations. If the brushes are taken care of properly you wont have to purchase another set for a very long time.
