Vitamin C may be one of the vital talked about substances in skincare, however additionally it is one of the vital misunderstood. Between proportion debates, oxidation fears, and layering confusion, the science usually will get buried beneath the hype.
For chemist and founder Marie Veronique Nadeau, the dialog begins with biology. Vitamin C is important to collagen manufacturing, mobile restore, and long run pores and skin resilience. No Vitamin C equals no collagen. The true query just isn’t whether or not it is best to use it, however which type your pores and skin can truly tolerate and profit from.
By her model Marie Veronique, she has developed two distinct approaches to topical Vitamin C: the antioxidant pushed Nutritional vitamins C+E+Ferulic Serum, and the gentler, spinoff based mostly C Remedy Serum designed for extra delicate or reactive pores and skin sorts. Each replicate her longevity first philosophy and her perception in good formulation over pattern chasing.
We sat down with Marie to decode what Vitamin C is de facto doing in your pores and skin, how to decide on the suitable model, what to keep away from, and why pairing it strategically with retinol could also be one of the vital highly effective strikes you can also make for long run pores and skin well being.

In Dialog with Marie Marie Veronique Nadeau
How ought to somebody incorporate Vitamin C into their morning and/or night routine? Ascorbic acid remains to be very a lot the gold normal in skincare. For most individuals a serum containing ascorbic acid stabilized in an anhydrous system with a pH of 4 to 4.5 will probably be their first alternative, particularly one that’s additional stabilized with Vitamin E and ferulic acid. It may be used within the morning beneath sunscreen to acquire further anti-oxidant safety. It may be used at evening to assist in regenerative mechanisms similar to collagen manufacturing. Ascorbic acid hydroxylates proline, and is among the first steps in collagen biosynthesis- no Vitamin C, no collagen.
Individuals who have hassle tolerating a low pH, i.e., have delicate or sensitized pores and skin or inflammatory circumstances similar to rosacea, needs to be on the lookout for a Vitamin C spinoff of their serum. Nobody ought to attempt to apply Vitamin C instantly onto their pores and skin—this may be very damaging.
Can you employ Vitamin C with retinol? Sure, completely, and anybody desirous about pores and skin longevity will need to. You should utilize them collectively (layered) or cut up them into morning and night utilization. Use vitamin C within the daytime for its antioxidant properties and retinol at evening, once you get the perfect profit from its signaling properties that ship directions to the fibroblasts to make extra collagen. You get improbable synergy from utilizing each—Vitamin C supplies a obligatory step in collagen manufacturing, whereas retinol converts to retinoic acid within the cell, the place it binds to receptors that act as chemical messengers that inform processes similar to upregulation of collagen manufacturing and cell turnover and downregulation of melanin manufacturing (for brighter pores and skin).
What ought to folks search for (and keep away from) when deciding on a Vitamin C product? First, keep away from AA (ascorbic acid) powders which can provide you an acid burn.
Individuals on the lookout for protecting and longevity advantages ought to search for a serum with Vitamin C as ascorbic acid together with helper antioxidants like Vitamin E and ferulic acid.
For folks with delicate or sensitized pores and skin, search for a Vitamin C spinoff. You may refine your search to search for the spinoff that conforms to your particular wants. For instance, folks on the lookout for pores and skin brightening results ought to get hold of substances like glyceryl ascorbate and tetrahexyldecyl ascorbate. Individuals with zits points ought to search for SAP (sodium ascorbyl phosphate) for its capacity to cut back sebum oxidation in congested pores, a significant reason for zits. And naturally delicate, challenged pores and skin that’s in that age group the place collagen constructing is necessary ought to hunt down THA (tetrahexyldecyl ascorbate) and MAP (magnesium ascorbyl phosphate); each have good efficiency information for penetrating to the fibroblast to hydroxylate proline. The cell releases hydroxyproline, a obligatory part of collagen, and the arduous and quick rule is: no Vitamin C = no collagen!
How does Vitamin C work together with different energetic substances like retinoids, AHAs/BHAs, and peptides?
Vitamin C + retinol has vital synergistic interactions, with signaling from retinol plus hydroxyproline from Vitamin C offering advantages throughout age-delay and pores and skin brightening platforms. Along with boosting collagen manufacturing, the 2 additionally work together by way of epigenetic mechanisms to advertise epidermal thickening.
Interplay of AHAs and BHAs can enhance pores and skin sensitivity as they’re acids. Vitamin C has monumental advantages and can be utilized daily, whereas an AHA for exfoliation can be utilized as soon as every week, individually from Vitamin C. I like to recommend lactic acid for exfoliation remedies, because it has, along with being mild, a terrific pores and skin longevity profile—together with boosting collagen manufacturing and dermal thickening. It additionally acts as a signaling molecule to manage autophagy.
Vitamin C and peptides: It’s in all probability greatest to make use of Vitamin C and peptides individually, due to potential pH conflicts the place results are neutralized (notably within the case of copper peptides). Use vitamin C within the morning for antioxidant advantages and peptides at evening for restore functions.
Your model presents Nutritional vitamins C+E+Ferulic Serum and C-Remedy Serum, at a excessive degree, what’s the core distinction in objective and efficiency between these two? Nutritional vitamins C+E+Ferulic Serum combines highly effective antioxidants to ship elevated antioxidant safety, plus Vitamin C as ascorbic acid promotes collagen manufacturing. It’s designed for folks with regular pores and skin who want safety and wish the age-delay advantages of Vitamin C delivered in a method that produces most outcomes.
All people wants Vitamin C, however not everybody can use ascorbic acid. That is why we developed C-Remedy Serum, for these folks on the spectrum with Vitamin C sensitivity or different points. Vitamin C derivatives are secure and ship l-ascorbic acid to the pores and skin with out creating points with sensitization. As well as, every spinoff in C-Remedy Serum performs a particular vary of duties. Scientific research present that: sodium ascorbyl phosphate prevents oxidation of particles in congested pores to clear breakouts, glyceryl ascrobate moisturizes and improves barrier operate, and magnesium ascorbyl phosphate and tetrahexyldecyl ascorbate impede hyperpigmentation processes and enhance collagen ranges. The formulation is rounded out with alpha-lipoic acid –the common antioxidant that helps forestall injury to mitochondrial DNA.
Are there substances it is best to keep away from pairing with both serum? They’re designed to work with most substances however bear in mind the principles—you don’t need to keep away from decreasing pH so watch out in combining with AHAs, BHAs, and the opposite rule: Defend by day and restore by evening—so use antioxidants by day and retinol and different sign peptides for restore by evening.
How are you going to inform in case your Vitamin C serum has oxidized and is now not efficient? The colour ought to stay the identical as once you first use it, if it begins turning darker that could be a signal that it may be oxidizing.
How does your components differ from different C+E+Ferulic serums available on the market? We take note of synergy, each inside the formulation, the place we need to enhance the antioxidant energy of the serum, however inside the wider context of how Vitamin C works with different protecting and regenerative merchandise, notably sunscreen and retinol serums.
We incorporate superior expertise in a lightweight serum that may be layered with sunscreen by day to ship antioxidant safety, or with a retinoid product at evening to make sure that enough l-ascorbic acid is in pores and skin tissue to reply to retinoic acid signaling to make collagen.
Vitamin C should be current to hydroxylate proline for the formation of a secure collagen triple helix. To completely optimize pores and skin well being and longevity, we suggest combining oral dietary supplements, taken each day, with both topical Nutritional vitamins C+E+Ferulic Serum or C-Remedy Serum, additionally for use each day.
Is there an rising ingredient or new analysis course in antioxidant science that you simply’re enthusiastic about in skincare? Sure, there are new research indicating that Vitamin C performs a job in pores and skin regeneration by way of epidermal thickening—which provides enormously to its longevity profile, because it addresses the crepey pores and skin situation that’s of particular concern for mature pores and skin. Appearing by the epigenetic mechanism known as DNA demethylation, Vitamin C drives TET enzymes to reactivate genes that enhance keratinocyte proliferation and enhance epidermal thickness.
Synergy is the opposite thrilling information; use of retinol and Vitamin C collectively enhances the pores and skin thickening course of—retinol acts as a signaling molecule to upregulate and enhance TET enzymes inside the cell, whereas Vitamin C acts because the cofactor to recharge the enzymes. Utilizing the 2 nutritional vitamins collectively influences the epigenome and promotes pores and skin longevity.
