NAD, the newest trending beauty ingredient, is believed to effectively combat the signs of skin aging.

 

Staying updated on the latest trends in skin care can be quite a demanding task. Just when you think you've mastered the differences between retinols and retinals, and hyaluronic acids and polyglutamic acids, a new and exciting ingredient emerges.

The most recent addition to the scene is an ingredient with a rather long name - Nicotinamide Adenine Dinucleotide, commonly known as NAD. It is sometimes referred to as NAD+, which falls within the NAD category. While NAD is not entirely new, as it already exists in our cells, recent scientific advancements have made it possible to utilize it in skin care products, as well as supplements and IV drips. There is speculation that NAD could potentially hold the key to preventing and reversing skin aging.

If you desire to maintain a youthful and smooth complexion while keeping fine lines at bay (and who doesn't?), we recommend continuing to read to determine whether incorporating NAD into your beauty routine is worth it.

👉An Introduction to NAD ?

According to Sam Bunting, a cosmetic dermatologist and founder of a skin-care brand based in London, NAD is a coenzyme that plays a crucial role in cellular metabolism. It is essential for energy production and is involved in various cellular processes. However, as we age, the levels of NAD in our cells decrease, with a 50 percent drop by the age of 40. This decline in NAD levels affects the efficiency of our skin, making it sluggish and slow. Boosting NAD levels in the skin is not a simple task, as it requires innovative systems to stabilize and deliver it effectively. Alternatively, other ingredients can be used to recharge existing NAD. Invity, a science-focused skin-care brand led by biotechnologist Eugene He, takes a two-pronged approach by using NAD as an ingredient and NAD precursors. Dr. Bunting, on the other hand, focuses on the recharging aspect in her products. Dr. Bunting introduces a new ingredient called Sunflower Shoot Extract (SSE), which helps to increase NAD levels. SSE enhances the recycling of NAD+ within the cells, resulting in a higher amount of available NAD+. It's like connecting a charger to your skin cells, rejuvenating and boosting them without the hassle of changing batteries or constantly relying on an external power source.

👉What advantages does NAD offer in terms of skincare?

We have fully charged and prepared it for action, but what exactly does NAD do for our skin? According to Dr. He, "It is widely recognized that optimized NAD levels go beyond providing energy to your cells. They enhance cellular functions, promote skin health, and slow down the aging process. At a superficial level, NAD acts as a skin conditioner, normalizing and supporting the skin barrier. The results include clearer skin, a more even complexion, improved hydration and moisturization, reduced flakiness, and diminished redness." In essence, NAD offers a multitude of benefits, from reversing the effects of time to reducing skin sensitivity, making it a highly promising component. Moreover, obtaining NAD is much simpler than acquiring the elusive Philosopher's Stone. To fully harness these advantages, it is recommended to incorporate NAD into leave-on products such as serums and moisturizers. Serums typically contain the highest concentration of NAD and NAD-boosting ingredients..

👉Adverse Effects of NAD.

One advantage of NAD is its natural presence in our skin, similar to hyaluronic acid and ceramides. This familiarity allows it to be well tolerated by all skin types, including sensitive ones. Dr. He confirms that NAD is generally safe and essential for various cellular processes. Being an essential part of life, it can be used on all skin types and at all life stages. In contrast, retinol, a popular anti-aging ingredient, is not recommended for very young skin and can cause initial irritation. NAD, on the other hand, is like a familiar friend who is always welcomed, while retinol can be compared to a stranger who initially creates some awkwardness. Moreover, NAD works well with other ingredients and can enhance their effects. Dr. Bunting highlights the synergy between NAD and retinoids, explaining that maximizing the benefits of retinoids requires cellular energy, which NAD provides. Additionally, NAD strengthens and repairs the skin barrier, making it easier for the skin to tolerate retinoids. However, there is one exception mentioned by Dr. He regarding exfoliating products. Due to the instability of NAD+, NAD precursors, and certain NAD boosters, it is advised to avoid using them simultaneously with highly acidic or alkaline products such as skin peels. Generally, it is advisable not to overload the skin with too many products at once, as this can lead to more problems than solutions.
