When (and how) to use C-Esta Face Serum by Jan Marini

Before using the Jan Marini vitamin C serum, shake well. Prior to use, leave the plastic lid in place, invert, and tap the top of the container several times into the palm of your hand. If you experience difficulty when dispensing, repeat and pump the product into the hand while inverted. Apply Jan Marini's C-ESTA Face Serum sparingly morning and evening to clean skin. Apply over the entire face, neck, and behind the ears.
