NAD⁺ is a naturally occurring coenzyme found in all of our cells, including the skin. It plays a crucial role in the cells' energy production, recovery, and repair abilities. Over time, the skin's natural levels of NAD⁺ decrease, which can affect how the skin looks and functions. The skin may appear more tired, less resilient, and more uneven in texture and tone.
Skincare products focusing on NAD⁺ are therefore used to support the skin's fundamental functions. The goal is not a quick, temporary effect, but to strengthen the skin's quality over time by working on a cellular level.
How does NAD⁺ work and why is it used in skincare?
NAD⁺ functions as a central component in the skin's biological processes. Without sufficient levels of NAD⁺, the skin's cells have a harder time producing energy and managing external stress. This, in turn, affects the skin's ability to renew itself, repair small damages, and maintain a strong protective barrier.
In skincare, NAD⁺ is used as part of a more long-term skin health approach. Instead of solely focusing on superficial effects, such as immediate glow or temporary plumpness, NAD⁺-based skincare aims to support the skin's own systems so that the skin can function better over time.
What is NAD⁺?
NAD⁺ stands for Nicotinamide Adenine Dinucleotide and is a coenzyme, meaning a substance that helps enzymes in the body perform their work. Enzymes can be described as small biological “tools” that drive chemical reactions in the cells. For these reactions to work, auxiliary substances are often required, and NAD⁺ is one of the most important.
NAD⁺ as a natural coenzyme in skin cells
In the skin, NAD⁺ participates in several fundamental processes. It is involved in the cells' energy metabolism, in repair mechanisms, and in how the skin handles oxidative stress from, for example, UV radiation and air pollution. That is why NAD⁺ is often associated with concepts like energizing skincare, recovery, and long-term skin health.
How does NAD⁺ work in the skin?
The skin is an active organ that is constantly working to renew cells, repair damage, and protect the body from external influences. All these processes require energy and a well-functioning cellular environment. NAD⁺ is an important part of this system.
NAD⁺ and skin's energy production
Skin cells need energy to be able to build new cells, produce lipids for the skin barrier, and maintain their normal functions. NAD⁺ is involved in the processes that make it possible for cells to convert nutrients into usable energy.
When the cells' energy levels are sufficient, the skin often appears more vital, even, and resilient. When energy levels drop, the skin can instead feel dull, tired, or slow in its recovery.
NAD⁺, cell renewal, and repair
Every day, the skin is subjected to stresses such as sun, temperature changes, pollution, and sometimes harsh skincare routines. The body has its own repair systems to handle this, and several of these systems are linked to NAD⁺.
Skincare that supports NAD⁺ is therefore often used in routines where one wants to help the skin recover, especially if the skin feels weakened, stressed, or over-treated.
Why the skin's NAD⁺ levels decrease with age
As we age, the body's natural production and availability of NAD⁺ decrease. At the same time, the skin has often accumulated more external influences over time. When the levels of NAD⁺ become lower, certain cell processes can become less effective, which is one of the explanations for why the skin's structure, resilience, and recovery ability change with age.
It's important to understand that NAD⁺ does not stop the skin's natural aging, but ingredients that support the skin's function can contribute to the skin aging in a more balanced and healthy way.
Why is NAD⁺ good in skincare?
NAD⁺ is interesting because it addresses the skin's function rather than individual symptoms. It is an ingredient idea that suits those who want to work on skin quality in depth.
Benefits of NAD⁺ for skin quality and radiance
Skincare with NAD⁺ can help the skin feel more balanced, even, and recovered. Many find that the skin gains better radiance and a more stable feeling over time, rather than a short-term cosmetic effect.
NAD⁺ compared to classic ingredients like vitamin C and collagen
Different ingredients serve different functions in skincare. Vitamin C is mainly used for radiance, antioxidant protection, and a more even skin tone. Collagen in skincare usually acts as a moisturizing and softening ingredient on the skin's surface.
NAD⁺ differs by focusing on the cells' energy functions and recovery. Therefore, NAD⁺ is often combined with other active and barrier-strengthening ingredients in a more complete routine.
How to use skincare with NAD⁺?
Products with NAD⁺ are usually used as serum, essence, or cream. For best effect, they are applied after cleansing and before a moisturizer that helps retain moisture and active ingredients in the skin.
When in the skincare routine should NAD⁺ be applied?
NAD⁺ is suitable for both morning and evening routines. In the morning, it is always followed by sunscreen. In the evening, it can be combined with moisturizing or barrier-strengthening products depending on the skin's needs.
Can NAD⁺ be used together with retinol and niacinamide?
NAD⁺ often works well with retinol, especially in routines where you want to support the skin's recovery. Retinol can be effective but demanding, and therefore ingredients that contribute to balance and support are appreciated.
Niacinamide is not the same as NAD⁺, but vitamin B3 is linked to the body's NAD⁺ system. The combination is often used to support the skin barrier and create a more even skin tone. Always introduce new active ingredients gradually, especially if the skin is sensitive.
NAD⁺ in Korean skincare
Korean skincare is based on the idea of long-term skin health, where the focus is on hydration, barrier function, and consistent routines. NAD⁺ fits well into this philosophy because the ingredient supports the skin's own biological processes.
Why NAD⁺ fits the K-beauty philosophy
K-beauty often involves building strong and stable skin through gentle yet effective steps. NAD⁺ is therefore often used in products aimed at strengthening the skin's resilience and recovery rather than providing aggressive quick results.
Common ingredients combined with NAD⁺ in K-beauty
To create a balanced formulation, NAD⁺ is often combined with ceramides, moisturizing ingredients, soothing extracts, and antioxidants. Together, these ingredients contribute to skin that feels more hydrated, protected, and even over time.
Who is NAD⁺ skincare suitable for?
NAD⁺ can suit many skin types, but is particularly relevant for skin that needs extra support and recovery.
Skin types that benefit especially from NAD⁺
- Mature skin that wants to maintain firmness and radiance
- Dry skin that needs a strengthened skin barrier
- Combination skin that wants balance without feeling heavy
- Stressed or tired skin that is perceived as pale
- Skin that easily becomes reactive from strong skincare routines
If you have very sensitive skin, it is wise to choose products where NAD⁺ is combined with soothing and barrier-strengthening ingredients.
When NAD⁺ is a good choice in an anti-aging routine
NAD⁺ is suitable for routines where the goal is to maintain the quality of the skin rather than just treating individual signs of aging. It can be used as a base in an anti-aging routine or as a restorative element when the skin feels stressed.
Common mistakes to avoid with NAD⁺ in skincare
- Expecting immediate results instead of giving the skin time
- Combining too many active ingredients at once
- Skipping moisturizer and sunscreen
- Changing products too often without evaluating the effect
A thoughtful and consistent routine usually gives the best results.
Common questions about NAD⁺ in skincare
Is NAD⁺ the same as niacinamide?
No. Niacinamide is vitamin B3, while NAD⁺ is a coenzyme found in cells. They are related but not the same.
Can NAD⁺ be absorbed through the skin?
Skincare uses forms and systems adapted for topical application. The goal is to support the skin's function and skin feel over time.
Is NAD⁺ safe for sensitive skin?
Yes, in most cases, especially when the product also contains soothing ingredients.
Can I use NAD⁺ together with retinol?
Yes, it is common. NAD⁺ is often used as a support in more active routines.
How long does it take before you see results?
It varies, but many experience improved skin quality after a few weeks of consistent use.
