INJECTION VS HYALURONIC ACID CARE: WHO WINS THE EFFICIENCY MATCH ?
Before to get into the match, I will give you all the cards to understand well. It there are different molecular weights, that is-to-different sizes of hyaluronic acid classified into 4 categories:
very high molecular weight
high molecular weight
medium weight
small weight (and no, this one is not green…)
In depending on their size, hyaluronic acid molecules will penetrate more or less deeply into the skin. Imagine think of it like a funnel: very high molecular weight hyaluronic acid with its large size will stay at the top of the funnel, that is, on the surface of your skin. Conversely, small molecular weight hyaluronic acid, thanks to its small size, can slip to the bottom of the funnel, which is-to-to penetrate deeply into your skin.
INJECTIONS WITHHYALURONIC ACID
In hyaluronic acid injections, very high molecular weight is mixed with high molecular weight and directly injected into the dermis, the second layer of the skin(1). By performing these injections, the goal is a volumizing effect to fill the deep hollows of the face by modifying its shape.
THE BOOSTER SERUM WITHACID HYALURONIC
Let’s see now the difference with hyaluronic acid care, and in this area I will talk to you about the choices of Novexpert. Our Serum Booster to theAcid Hyaluronic is, for example, one of the few serums in the world to contain all 4 sizes of hyaluronic acid! It’s an innovation that breaks the codes of traditional cosmetic care, and we formulated it so that hyaluronic acids of different sizes play complementary roles within the skin. The more substantial: the very high and high molecular weights act at the tissue level, providing a smoothing and hydrating effect, like a biological iron! Conversely, the smaller ones can slip deeper into the skin and act at the cellular level: they stimulate the cells of the skin (the keratinocytes). The epidermis is 3 times thicker in the presence of medium molecular weight hyaluronic acid, impressive(2) !
The injection therefore fills the deep hollows of the face while the Serum Booster fills surface hollows and stimulates our cells deeply. The the two can therefore be complementary !
THE SECRET LIFE OF HYALURONIC ACID WITHIN THE SKIN
I I may surprise you, but the hyaluronic acid in our skin has an extremely short lifespan: it is destroyed and renewed… approximately every day by our cells. Yes within 24 hours! Our body makes a point of providing us with "fresh" every days(3).
The hyaluronic acid in products Novexpert therefore integrated into this cycle because it is 100% natural and biomimetic, it is-to-identical to that of our skin.
I I hear you say in front of your screen: "But when my colleague gets a hyaluronic acid injection, the effects last more than a day ? »
You you are absolutely right, the hyaluronic acid from injections has a lifespan of 6 to 9 months… Why ? Because that it is not alone, it is coupled with a synthetic cross-linking agent that acts like a bodyguard: it prevents the natural degradation of hyaluronic acid and thus it is preserved for several months instead of one day(4).
WHAT HAPPENS TO THE BODYGUARD IN OUR SKIN ? DIVING INTO LUNKNOWN...
That’s good but… (because there is always a "but" when we prevent nature from doing its job) what is the future of this bodyguard in our body? Today, we do not know. Being synthetic in nature, it is not or barely biodegradable, and we do not have enough scientific information to know what happens to it in our skin in the long term.
Moreover, our own hyaluronic acid renewal cycle is well organized! The destruction of "old" hyaluronic acid sends cellular signals to produce new hyaluronic acid, like a relay race! However, if the hyaluronic acid is not destroyed (as with injections), it is reasonable to think that fewer signals for renewal will be created, so less fresh hyaluronic acid will be synthesized.
Since the creation of Novexpert, I have believed in a holistic approach to skin health. In this specific case, to increase the amount of hyaluronic acid in the skin, injections or our Booster are effective solutions, but they are not the only ones. Your lunch or dinner can also play an important role!
EAT TO BOOST YOUR HYALURONIC ACID SYNTHESIS
Eating yes, but not just anything! Some foods can increase hyaluronic acid synthesis thanks to their flavonoid or vitamin C content, for example. Researchers discovered this through studying the diet of the Japanese village Yuzuri Hara, where inhabitants have a very long life expectancy and preserved skin despite sun exposure. Since reading publications on the subject, I include the following foods in my meals; it’s up to you to try them too!
Foods rich in flavonoids(5): cashew nuts, olive, garlic, shallot, plum, blackberry, cherry…
Foods rich in vitamin C(6): kale, parsley, goji berry, blackcurrant, kiwi…
Theessential
✔ The injections contain large hyaluronic acid molecules that are injected directly into the second layer of the skin (the dermis) to fill deep hollows.
✔ Ourhyaluronic acid serum contains all sizes of hyaluronic acid (wow !) to fill surface hollows and stimulate our cells in depth.
✔ The hyaluronic acid of Novexpert is 100% natural and biodegradable, whereas that of injections contains a "bodyguard" molecule and its fate in the body is unknown.
✔ You you can increase your hyaluronic acid amount by eating ! Real real !
