I refer to this as my glue to help keep my make-up on during the day.  I have very oily skin and by the end of the day my makeup would be gone.  I am not the type to reapply makeup during the day.  I have tried other products and none has ever worked like this product.  My pores do not get clogged.  The PCA skin line is the BEST on the market.  Buy, buy, buy it for fabulous skin.
