N1O1 Nitric OxideTM Activating Serum with antioxidants (formerly called Pneuma) for the skin helps with:

  • Improving the appearance of fine lines and wrinkles
  • Overall tone, texture and clarity of the skin
  • Softening the signs of aging

Loss of Nitric Oxide with aging leads to increased signs of aging including poor complexion, loss of barrier function and increased appearance of fine lines and wrinkles. Therefore, in people that have lost the ability to produce Nitric Oxide by the cells in the skin, Nitric Oxide has to be produced for them. 

N1O1 Nitric Oxide™ Activating Serum is a patent pending, innovative dual chamber technology that produces Nitric Oxide gas when the contents of both chambers are mixed together. That is the beauty of the N1O1 Nitric Oxide™ Activating Serum. If your body cannot produce Nitric Oxide, N1O1 does it for you.  

1-Month supply in each bottle

N1O1 Nitric Oxide™ Activating Serum with antioxidants is a patent pending serum that contains Vitamin C and works synergistically with Nitric Oxide to improve the appearance of skin.

N1O1’s synergistic Nitric Oxide dual chamber delivery system contains a high-concentration of powerful antioxidants proven in peer-review studies to help prevent the free radical damage that can lead to the appearance of premature aging.

Because there are no chemical preservatives that can permeate into your skin, the all-natural antioxidants may develop a slight amber hue. This is perfectly normal, does not affect N1O1’s effectiveness and lets you know N1O1 Activating Serum contains only the healthiest ingredients.

Specific Ingredients include: Water, Ascorbic acid, Polysorbate 20, hydroxyethylcellulose, sodium nitrite, d-Tocopheryl Acetate, dehydroacetic acid, benzyl alcohol, sodium sulfite, sodium metabisulfite, tetrasodium EDTA.

  • Fragrance Free
  • Phthalate & Paraben Free
  • No Animal Testing
  • Patent Pending Technology

Suggested Use 

Use in the morning and evening on clean skin. 

  • Dispense a single pump from each chamber. Mix together and apply to the face and neck. 
  • Allow serum to fully absorb 1-2 minutes before applying or continuing with your normal daily skin care regime. 

N1O1 Nitric Oxide™ Activating Serum can be used as a stand-alone skin treatment or as a primer for your existing skin care regime. N1O1 prepares your skin to make any skin care treatment work better.

When serums from the dual chambers are mixed together, the Nitric Oxide is activated. As a result of the Nitric Oxide activation certain skin types could show a pink tone for a few minutes. 

It is common for Vitamin C to turn an amber color over time. This does not affect the activity or benefits of this product.

Faulty Container, No Results

When the serum arrived, I was excited to use it. The 2nd nozzle didn’t work, so I submitted a request for customer support. Didn’t receive any. Got a standard email reply that had nothing at all to do with my request. What little I could get out of the container hasn’t produced any results. I can’t technically say the customer service is bad, because there isn’t any to begin with.
