NMN (nicotinamide mononucleotide) and NR (nicotinamide riboside) are two compounds that have gained popularity in the world of skincare due to their potential anti-aging properties.
Both NMN and NR are precursors to nicotinamide adenine dinucleotide (NAD+), which is a coenzyme involved in many cellular processes, including DNA repair, energy production, and cellular signaling. NAD+ levels decrease as we age, and this decline has been linked to the aging process and age-related diseases.
By increasing NAD+ levels, NMN and NR may help to support healthy cellular function and promote healthy aging. This can potentially lead to benefits for the skin, such as reducing the appearance of fine lines and wrinkles, improving skin elasticity, and promoting a more even skin tone.
While research on the effects of NMN and NR on the skin is still in its early stages, some studies have shown promising results. For example, a study published in the journal Nature Communications found that oral supplementation with NMN improved skin barrier function and reduced water loss in mice. Another study published in the Journal of Cosmetic Dermatology found that a topical formulation of NR improved skin hydration and reduced the appearance of fine lines and wrinkles in human participants.
