NAD+

NAD+ (nicotinamide adenine dinucleotide) is an essential coenzyme found in every cell of the body. It plays a role in numerous biological processes, notably cellular energy production, DNA repair and the regulation of oxidative stress. NAD+ can also be utilised in cosmetics to care for the skin and hair.

FAQ about nad+

Why is NAD+ important for the skin?

The NAD+ supports cellular regeneration, helps repair DNA and combats oxidative stress, thereby contributing to healthier skin.

What are the NAD+ precursors used in cosmetics?

Nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN) are commonly used to enhance NAD+ levels in skin cells.

Can NAD+ help reduce wrinkles?

According to certain studies, the NAD+ could help reduce the visibility of wrinkles by stimulating collagen production.

Are there any NAD+-based dietary supplements?

Yes, NAD⁺-based supplements are available to boost systemic NAD⁺ levels. However, their benefits for the skin have been little explored.

Can NAD+ stimulate hair growth?

According to some promising research, the NAD+ could promote hair growth. However, these effects have yet to be demonstrated in clinical studies.

What is the difference between NAD+ and niacinamide in cosmetics?

NAD+ is an active coenzyme within cells, whereas niacinamide is a form of vitamin B3 that serves as a precursor to its synthesis. In cosmetics, niacinamide is widely used because it is stable, well-tolerated and capable of penetrating the skin. It therefore acts indirectly on the metabolic pathways associated with NAD+.

Is NAD+ suitable for all skin types?

Yes, NAD+ is an active ingredient suitable for all skin types, including sensitive skin. However, it remains essential to carry out a patch test before first use.

Does NAD+ have an effect on skin radiance and complexion uniformity?

Indirectly, yes. By supporting cellular metabolism and repair mechanisms, a sufficient level of NAD+ promotes more efficient skin renewal. This leads to more radiant skin and a more even complexion.

Is NAD+ relevant to helping the skin heal?

Yes, the NAD+ supports skin regeneration and helps maintain adequate hydration levels, two mechanisms essential for effective wound healing.

Is there a link between NAD+ and skin inflammation?

The NAD+ is involved in the regulation of certain inflammatory pathways via the activation of sirtuins. A decrease in its levels is often associated with an exacerbated inflammatory response. We can therefore cautiously hypothesise that NAD+ could be beneficial for skin prone to inflammation or redness.
