1. NAD+
Energy production
NAD⁺ is a key component in the function of mitochondria, which produce energy in our cells. It transfers electrons in redox reactions, which are essential for all ATP-generating pathways: glycolysis, the Krebs cycle, and oxidative phosphorylation.
Regulation and signaling
NAD⁺ is essential for the activity of important enzymes, including sirtuins and PARP (poly-ADP-ribose polymerase). These enzymes are involved in:
- cellular aging and longevity maintenance;
- DNA repair after damage;
- regulation of sleep-wake cycles;
- immune response modulation.

NAD⁺ and aging
NAD⁺ levels in the human body decline with age and with excessive body weight. Low NAD⁺ contributes to aging signs in skin, as this molecule is involved in controlling oxidative stress. Such stress is one of the most fundamental biochemical processes driving aging. Research shows that increasing NAD⁺ levels improves metabolic health and slows aging.

2. NMN
In addition to NAD⁺ itself, its precursors, particularly nicotinamide mononucleotide (NMN), have demonstrated excellent anti-aging effects. NMN is converted into NAD⁺ with the help of the enzyme phosphoribosyltransferase.

3. Exosomes
Exosomes are small extracellular vesicles with a bilayer phospholipid membrane. They contain mRNA and DNA, lipids, ribosomal proteins, metabolic enzymes, ligands, cytoskeletal molecules, chaperone proteins, etc. These nanovesicles are stable, biocompatible, and minimally immunogenic. Because they fuse with recipient cell membranes, exosomes in Meamo Jeunetique NAD+ work as efficient targeted carriers. Their cargo can stimulate intercellular communication and activate pathways for tissue regeneration.

Gives a glow
Looking forward to meso and microneedle with left over . Will try to come back and post results in a few months.
Love this new product
Use this for micro needling and my skin is absolutely glowing! Easy to mix up and use and the shipping was lightning fast. This is going to be in my regular rotation from here on out.
I need to try it
