I LOVE this product. Its very interesting to watch as the bubbles form!
You do not need a thick layer. Don't go to close to your nose or eyes as it does expand.
When applying to your face, make sure the container is closed as that foams as well
It does leave my face slightly tight and shiny, applying to at night is best (for me anyways) everyone is different

*I will definitely buy more in the future!*
I have nothing bad to say about this product.
