i will never live without this illuminator ..though it's pricey..but honest..i don care the price as long as it works...you basically apply this illuminator before you apply any liquid foundation..but i personally like to wear it alone..cause this product hides imperfection NATURALLY..and you are the only one who know the imperfection is gone because this is extremely natural that no one will ever notice..why not going to try this out at the chanel counter..oh..forgot to mention..this won't clog pores..
