COS Naturals, Vitamin C Serum, This is a very well made product.  I am very pleased with this product.  This is an anti aging serum to help fine line, dark circles and even skin tone.  This comes with a handy eye dropper for easy application.  This is also manufactured in the USA, which is very important to myself.  After applying, and drying it has no heavy feeling or sticky feeling, just apply your moisturizer or make up.  You will be pleased with this product.  Thank you for allowing me to try your product  I recommend this product.  Disclosure: I received this product at a discount in exchange for my honest review.
