NAD+

NAD+ (nicotinamide adenine dinucleotide) is an essential coenzyme present in every cell of the body. It is involved in numerous biological processes, including cellular energy production, DNA repair, and the regulation of oxidative stress. NAD+ can also be used in cosmetics for skin and hair care.

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.

Which NAD+ precursors are used in cosmetics?

Nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN) are commonly used to boost 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 systemically boost NAD+ levels. However, their benefits on the skin have been little studied.

Can NAD+ stimulate hair growth?

According to some promising research, the NAD+ may promote hair growth. However, these effects still need 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 thus acts indirectly on metabolic pathways related to NAD+.

Is NAD+ suitable for all skin types?

Yes, NAD+ is an active ingredient suitable for all skin types, including sensitive skin. However, a patch test upon first use is still recommended.

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

Indirectly, yes. By supporting cellular metabolism and repair mechanisms, adequate NAD+ levels enhance skin renewal efficiency, resulting in brighter, more even-toned skin.

Is NAD+ relevant for aiding the skin’s healing process?

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

Is NAD+ associated with skin inflammation?

The NAD+ plays a role in regulating certain inflammatory pathways via the activation of sirtuins. A decrease in its levels is often associated with an exacerbated inflammatory response. Therefore, we can cautiously assume that NAD+ may be beneficial for skin prone to inflammation or redness.
