What color is the serum supposed to be directly out of the bottle?

The bottle is a dual chamber system - one side of the bottle contains vitamin C, the other side contains liquid nitric oxide. When you use one pump from each side of the bottle, and mix the drops together in the palm of your hand, the vitamin C acts as the activating ingredient to activate the nitric oxide. The nitric oxide serum is clear, the vitamin C can be an amber color.

Should I use hyaluronic acid in addition to this, or does this replace hyaluronic acid?

Thank you for reaching out! You should use Hyaluronic Acid after using our Nitric Oxide Activating Serum. The serum help with the absorption of the HA...and will actually boost it! Hope this helps!

What percentage of nitric oxide?

Thank you for asking! The serum is a dual chamber bottle that contains nitrite in one chamber and Vitamin C in the other. The vitamin C is the activating agent which when mixed with the nitrite creates nitric oxide gas. The mixture is 100% nitric oxide. Hope this helps.
