Not Sure yet.
I used the No. 7 Serum then the Day Cream and then that night after washing my face I used the No. 7 Serum and then the Night Cream.  After two days of using this product, my face broke out in a red rash.  It has been three days of not using the product and tonight I'll use the Night Cream and then tomorrow I'll use the Day Cream and see what happens.  I like the feel of the cream so I hope that I reacted only to the Serum.Not
