I bought a pore minimizer from Clinique today. SA told me to apply after my moisturizer but when I reminded her I don't use Cliniques 3 step, she said that I probably should apply the PM first, then sunscreen. Does anyone use this product without using the other Clinique 3 step products and if so, does this really matter? If this PM will only work with Clinique products, I just need to take it back. How do you know if you are just creating more problems?
