Say goodbye to retinol, this molecule that we see more and more in our cosmetics could well be our new fountain of youth.
It is neither a new fashionable serum nor a cosmetic surgery technique. However, this biological nugget is on the lips of longevity specialists. Capable of “recharging” our cells like a battery, this mystery molecule redefines anti-aging standards. Deciphering an invisible revolution that could well send retinol into the closet.
If you’re a beauty fan, you already know it. Although it is still in its infancy, this molecule is starting to find a place of choice in cosmetic formulas. A few months ago, we were talking about it simply for its variant in the form of food supplements or, if you look at what Hollywood stars do, for its injectable version to avoid dehydration the day after the holidays. But it is now in our creams and serums that we find NAD+, or nicotinamide adenine dinucleotide. Quesaco? It is a coenzyme naturally present in our cells, playing a central role in our well-being: cellular energy production and DNA repair. Roughly explained: Imagine that your cells are factories. NAD+ is the essential electron carrier for converting nutrients into energy. Without it, the cell “idles”, which results in premature aging. But that’s not all: NAD+ activates an enzyme called sirtuins. Sirtuins repair DNA damaged by UV or pollution and regulate cellular stress. Finally, it ensures communication between cells. With age, she becomes confused; NAD+ reestablishes the connection for a more efficient cell. But here it is: with age, the levels of this molecule gradually decrease in the body. At 50, we only have half the capital we had at 20, which explains why the skin loses its ability to “repair itself” during the night.
Thus, for some time now, researchers and scientists have been interested in NAD+ from a cosmetic point of view. The proof is: many brands are releasing products containing it in the formula. The American brand Paula’s Choice, for example, launched its longevity serum, while Dermalogica released a sculpting body serum whose key ingredient is none other than this famous coenzyme. The key? An improvement in the firmness and elasticity of the skin, a radiant complexion, and better functioning of the skin cells which will then regenerate better during the night. A true conductor of our cells, NAD+ redefines the rules of the game. C
his new era of cosmetics now favors prevention and connection to our biology rather than correction. Keep your eyes peeled in the beauty aisles: you haven’t heard the last of it!
