Including a topical vitamin C serum to your skincare routine could also be a no brainer, however selecting the best one is a bit more sophisticated. When you’ve ever hung out searching vitamin C serums on-line, you’ve most likely seen the ingredient label by no means simply reads “vitamin C.” There are lots of completely different types of vitamin C utilized in skincare, and which one you select undoubtedly issues.
On this publish, I’ll clarify the vital function vitamin C performs in wholesome pores and skin growing older and offer you a information to a few of the commonest types of vitamin C in skincare. Let’s dive in!
What Are the Advantages of Vitamin C for Pores and skin?
Like all nutritional vitamins, vitamin C can’t be produced by our our bodies. As an alternative, it’s one thing we have now to get from exterior sources comparable to meals or dietary supplements. Most of us get sufficient vitamin C by means of our weight loss plan, and extreme deficiency could be very unusual. That mentioned, because it’s wanted for therefore many capabilities all through the physique, solely a small proportion of the vitamin C we ingest will make it to our pores and skin. That is why “supplementing” with a topical product is a good way to make sure your pores and skin is reaping all of the superb advantages vitamin C has to supply.
So, how precisely does topical vitamin C profit our pores and skin? There are three primary methods:
1. Vitamin C Protects Pores and skin Cells From Environmental Injury
This most likely isn’t information to you, however vitamin C is a potent antioxidant. It scavenges free radicals, that are unstable molecules that result in pores and skin injury and speed up pores and skin growing older. Free radicals are continually coming at us from so many alternative sources, together with UV mild from the solar, ozone, smoke, and air pollution (to call a number of). All of those are additionally accountable for a pure depletion of vitamin C in our pores and skin over time, which is why supplementing with a topical antioxidant product is so necessary.
Additionally, try this superb visible demonstration I did of how vitamin C slows down oxidation from free radical injury!
2. Vitamin C helps stop collagen breakdown and promotes more healthy collagen manufacturing.
After we speak about “anti-aging” in skincare, it’s usually in reference to an ingredient’s skill to stimulate collagen. That is no shock contemplating collagen performs such a key function in holding pores and skin wanting youthful. The truth is, after age 20, our pores and skin’s skill to replenish collagen decreases by about 1%-1.5% annually! Enter: vitamin C. First, it helps defend the collagen you have already got by inhibiting a bunch of enzymes that break down collagen. Second, it aids in more healthy collagen manufacturing because it’s a cofactor for 2 enzymes wanted to construct and cross-link collagen.
3. Vitamin C helps even out pigmentation for brighter-looking pores and skin.
Of all its advantages, vitamin C could also be best-known for its skill to create brighter extra even-toned pores and skin by fading blotchy hyperpigmentation. It does this by interrupting the over-production of melanin, which causes hyperpigmentation. It’s a fantastic device for managing hyperpigmentation issues comparable to melasma.
What Is the Greatest Type of Vitamin C in Pores and skin Care?
On the subject of vitamin C in skincare, there are two classes: energetic and inactive. The one energetic type is L-ascorbic acid, which is the bioavailable type of vitamin C (that means the shape our pores and skin is ready to use). All different types of vitamin C are thought-about inactive as a result of they should be transformed to L-ascorbic acid throughout the pores and skin earlier than they’ll get to work.
Inactive types of vitamin C are nonetheless constructed on the muse of L-ascorbic acid however have been modified to the purpose the place they’re thought-about completely different molecules. These modified variations can both be an ester type of vitamin C, or they could be a completely different compound fully the place different elements are added to stabilize the ascorbyl group. You’ll discover that each one the inactive kinds I speak about have “ascorb” someplace within the identify, which is how you already know it’s a kind of vitamin C (this may be useful to know when studying ingredient labels).
As I mentioned, there are tons of various types of vitamin C utilized in skincare, so I’ll simply be masking 4 of the commonest ones.
L-ascorbic Acid
As I discussed earlier, L-ascorbic acid is the energetic, bioavailable type of vitamin C. That is what our cells use to hold out any and all capabilities that require vitamin C. Due to this, L-ascorbic acid has been researched extra totally than another kind of vitamin C in skincare. It’s been confirmed past a shadow of a doubt to work effectively as an antioxidant. We additionally realize it’s efficient for each collagen synthesis and evening-out hyperpigmentation.
When you go for L-ascorbic acid, search for a serum that incorporates between 8% and 20%. That is the vary wherein research have proven it to be best. Your pores and skin solely takes in as a lot vitamin C because it wants, so going above 20% received’t work any higher and simply will increase the potential for irritation.
The issue with L-ascorbic acid
So if L-ascorbic acid is so tried and true, why even entertain different types of vitamin C? The issue with L-ascorbic acid is that it solely works successfully IF you’re capable of get it into the pores and skin, and therein lies the problem. Pure ascorbic acid is extremely unstable and because it’s an antioxidant, it desires to react with nearly every part in its setting. This contains mild, warmth, oxygen, water, and metals. This implies the ascorbic acid in your serum has a excessive probability of oxidizing earlier than it will get an opportunity to make it into your pores and skin. (Ever heard of vitamin C serums turning brown? That is why.)
A method manufacturers and formulators fight this oxidation is by including different molecules comparable to vitamin E or ferulic acid to their vitamin C serums. Each are confirmed to assist stabilize ascorbic acid and to make vitamin C more practical. Nonetheless, you must burn up any serums containing L-ascorbic acid fairly shortly, or they’ll go dangerous. A great buddy of mine who’s a beauty chemist informed me she avoids formulating with L-ascorbic acid as a lot as she will because it’s so troublesome and unpredictable to stabilize.
Along with stability points, L-ascorbic acid has a excessive potential for irritation. It needs to be at fairly a low pH to stay steady, so this will trigger pores and skin irritation (particularly in case you use merchandise with substances comparable to retinol or exfoliating acids). This makes it a nasty match for delicate pores and skin sorts, and it additionally isn’t advisable in case you wrestle with pimples.
Sodium Ascorbyl Phosphate
Subsequent up is our first inactive type of vitamin C, sodium ascorbyl phosphate. This vitamin C by-product is certainly extra steady than L-ascorbic acid however can nonetheless be fairly reactive. Because of this, it’s usually utilized in skincare formulation as an encapsulation. Basically what this implies is that the ingredient is put right into a protecting shell to assist it stay steady whereas getting the place it must go, aka into your pores and skin.
Producer research declare sodium ascorbyl phosphate gives the identical advantages as pure L-ascorbic acid, particularly with regards to pores and skin brightening and collagen synthesis. The secret is ensuring it’s steady throughout the formulation and that it’s capable of successfully penetrate into the pores and skin.
Ascorbyl Methylsilanol Pectinate
This one is a little bit of a tongue tornado, and that’s as a result of it’s truly a fancy mix of many compounds moderately than only a simple vitamin C by-product. Additionally inactive, this type of vitamin C is a good instance of further elements being added as a way of stabilizing the extra risky ascorbyl group.
On this case, the steadiness of vitamin C is vastly elevated by the addition of silanol. The silanol additionally aids in pores and skin penetration, that means this vitamin C compound has improved supply into the pores and skin. Lastly, silanol has been proven to strengthen the membranes of pores and skin cells, which makes them extra immune to assault by free radicals within the first place.
Tetrahexyldecyl Ascorbate
Final however not least, we have now the inactive type tetrahexyldecyl ascorbate (THD). This one is my private favourite and can be the celebrity of my Vitamin C&E Remedy. What makes THD so completely different from the opposite kinds of vitamin C I’ve talked about is the truth that it’s an oil-soluble ester type of vitamin C.
Since THD is solubilized by oil as a substitute of water, it received’t begin to react and convert into L-ascorbic acid till it comes into contact with the oils in your pores and skin. This makes it essentially the most steady of all of the types of vitamin C I’ve talked about to date. One other good thing about oil solubility is that it has a slower launch time than water-soluble molecules. This implies an extended window of energetic vitamin C in your pores and skin, and subsequently an extended window of safety.
The slow-release also can imply a decrease potential for irritation than different types of vitamin C. Additionally, since THD is oil-based, it doesn’t require a low pH the best way water-soluble kinds do. Once more, this will imply much less irritation.
Lastly, one of many causes I really like this ingredient a lot is that, other than L-ascorbic acid, it has a few of the most analysis behind it. One of many causes it’s so extremely studied is that it’s thought-about a quasi-drug in Japan because of its skill to enhance pores and skin pigmentation issues. Fairly cool, proper? What’s thrilling to me about THD is that it’s truly been confirmed in research to be similar to L-ascorbic acid when it comes to efficacy and outcomes. It has a stellar monitor file with regards to enhancing hyperpigmentation, and it could even enhance collagen synthesis higher than L-ascorbic acid.
To me, THD is the winner. The one draw back is that it’s costly to formulate with, which suggests it may be tougher to search out in skincare merchandise than different, cheaper types of vitamin C.
Be taught to Spot Types vs. Sources of Vitamin C
On a closing observe, I’d wish to shortly contact on the problem of kinds of vitamin C versus sources of vitamin C. All the substances I’ve coated on this publish are types of vitamin C, that means as long as they make it into your pores and skin you’re assured to be getting some quantity of energetic ascorbic acid.
I’ve seen some manufacturers will promote merchandise marketed as containing vitamin C, however you received’t truly discover any type of vitamin C on the ingredient label. As an alternative, they’ll embrace extracts of vegetation or fruits identified to be excessive in vitamin C. I’m not saying these substances are dangerous by any means (most of them have antioxidant properties and make nice companions to vitamin C), however they’re not dependable sources of energetic vitamin C. There’s actually no solution to say for certain whether or not you’re truly getting any usable ascorbic acid from them.
Now that you already know extra about one of the best kinds of vitamin C, listed here are 5 qualities it’s best to search for in an efficient vitamin C serum.
