ASCORBIC ACID, BETTER KNOWN BY ITS STAGE NAME: VITAMIN C!
Everyone talks about vitamin C, but do you know why it is so important? First of all, because it is THE essential vitamin for your skin, and to convince you, here is a number: 2000. Your epidermis contains 2000 times more vitamin C than vitamin A, for example (1)!
This champion is on all fronts to protect us but is especially known for its antioxidant power (2). It defends our cells against unstable molecules called free radicals that want to attack our cells and cause premature aging. We can be grateful to it!
ALL THAT IS PRECIOUS IS RARE!
Vitamin C is also widely discussed because we are constantly searching for it to avoid deficiency… Yes, humans are one of the few mammals that cannot produce their own vitamin C! We were able to millions of years ago, but evolution was not in our favor (3). So today, we must find it through diet (especially fruits and vegetables) or cosmetics.
By the way, do you know the fruit richest in vitamin C? No, it’s not the orange, nor acerola, but the Kakadu plum, an exotic Australian fruit. Just 3g of this tangy treat covers your daily vitamin C needs!
In second place on the podium are the better-known Goji berries (4), which are also a super source of vitamin C.
Regarding cosmetics, vitamin C is not so easily contained in a bottle. It is a fragile vitamin destroyed by light, water, and heat (4)! It’s not easy to preserve it in products that are often composed of nearly 70% water and stored in the warm, humid environment of our bathroom.
SUN & VITAMIN: IRRITATIONS GUARANTEED?
Now that vitamin C holds no secrets for you, let’s return to our issue and a phrase I often hear around me: “I can’t use vitamin C products in summer or my skin will get irritated!”
Let’s bust the myth right away… vitamin C is not sensitive to the sun!
But if many of you think otherwise, it’s no coincidence because often the products containing vitamin C are incompatible with sun exposure. This is due to their pH, a physical parameter that measures the acidity of a solution or product.
Let’s look inside the bottle to understand everything… For classic vitamin C to penetrate the skin effectively, it must be incorporated into a product with a very acidic pH, close to 3. To visualize how acidic that is, know that lemon’s pH is about 2.5! Applying such products is not recommended during sun exposure as it would cause irritation reactions and damage the outermost layers of your skin.
And this is really a problem because the more your skin is exposed to the sun, the more it needs vitamin C, as sun rays degrade it.
To summarize: our skin needs vitamin C when exposed to the sun, but classic cosmetic products are incompatible with sun exposure… It sounds like an impossible mission!
A CUTANEOUS SHOT OF VITAMIN C THANKS TO NOVEXPERT!
At Novexpert, challenges stimulate us. So formulating a vitamin C care product for everyone, usable in all seasons, even during sun exposure, became our priority.
Our scientific team, accompanied by our Doctors, embarked on this quest and developed a new generation vitamin C complex! A kind of super vitamin C with an unmatched track record.
To be preserved inside the bottle, this vitamin C complex was formulated to resist light, heat, and water. But the innovation lies especially in the fact that this formulated vitamin C can penetrate the different skin layers at a less acidic pH, close to that of the skin, about 4.5 (the facial skin pH (5) is not 5.5 but 4.7). This allows us to offer products like the Vitamin C Booster, whose pH is similar to that of the skin. It can therefore be used all day, even in summer. Success, mission accomplished for Novexpert scientists!
Our Booster Serum is unique in more than one way because it contains 30% of this vitamin C complex, a vitamin C 40X more stable. It is one of the highest concentrations worldwide for a cosmetic product. Yes, worldwide, I did not mistype. With it, you can provide your skin with the vitamin C it deserves without any worries. It is certified non-photosensitizing, non-photoallergenic, and non-phototoxic. It can therefore be used daily on all skin types, even the most sensitive, all day long. Enough to build a good stock of vitamin C!
I still want to remind you here that in case of prolonged sun exposure (over 20 minutes), it is recommended to apply a cream with a sun protection factor.
Now you know everything, so this summer, you can confidently slip our Vitamin C Booster into your pretty canvas bag. It’s a powerful ally to help your skin maintain its vitamin C stock.
The Essentials
JUST ENOUGH TIME TO DRINK A JUICE, FOR "BUSY" READERS!
✔ Vitamin C is THE skin vitamin: it outperforms all others by its very high concentration in the epidermis and dermis.
✔ SOS! Today, humans can no longer produce it and it’s not so easy to find in our environment.
✔ Vitamin C is NOT sensitive to the sun. However, classic products containing it can be, due to their acidic pH…!
✔ Novexpert to the rescue! We developed a vitamin C complex allowing the formulation of a Booster Serum with a less acidic pH that can be used in all seasons and on all skin types!
