Two types of sun care serums, for day and night, SPF50 to protect your skin from UV rays. - Brand: ANESSA - Product Name: Sun Dual Care - Day Serum: Day Serum - SPF: SPF50 - Night Serum: Night Serum I received these as samples when I made a purchase in June. The Day Serum is 6ml, and the Night Serum was originally in a pouch, so the capacity is unknown, but it's the same size as the Day Serum.
