As each a 35 yr esthetician and a skincare product formulator skilled in beauty chemistry, what I do know for positive is there are plenty of false hopes being offered in regards to the newest and best “miracle” components – and it’s really easy to fall into the advertising and marketing hype.
I’ve seen plenty of components come and go and are available again once more (hiya hyaluronic acid!) however the one which has remained regular is vitamin C. Why? As a result of it really works for night out pigmentation by interrupting the over-production of melanin which causes hyperpigmentation. Plus, working with faces hands-on, I’ve seen unimaginable enhancements in my shoppers pores and skin, giving their pores and skin the brightness that they want.
However…not all vitamin C components and what’s now thought-about “the gold commonplace” is Tetrahexyldecyl Ascorabate, often known as THD Ascorbate.
So, let’s do a deep dive into this ingredient, we could?
What’s THD Ascorbate?
THD, or Tetrahexyldecyl Ascorbate, is an inactive type of vitamin C. What makes THD Ascorbate so uniquely totally different from different types of vitamin C is that it’s an oil-soluble ester versus being water-soluble. When it’s oil-soluble, it means it gained’t begin to react and convert into L-ascorbic acid till it hits the oils in your pores and skin, making it probably the most steady in comparison with different types of vitamin C. Plus, because it’s solubilized by oil as an alternative of water, it doesn’t require a low pH just like the water-soluble variations do.
Why Select THD Ascorbate Over Different Forms of Vitamin C For My Face?
Have you ever ever gotten a stinging sensation from vitamin C merchandise with Ascorbic Acid, Sodium Ascorbyl Phosphate and Ascorbyl Methylsilanol Pectinate? Yep, that is a sign of their low pH together with probably the state of your pores and skin’s barrier. Whereas stinging from vitamin C with a low pH is par for the course, (learn extra about stinging from skincare products), that doesn’t imply your pores and skin appreciates the day by day “no ache, no acquire” assault that it will get uncovered to within the quest for brighter pores and skin. Your pores and skin’s pH resides round 5.0 and most of the water-soluble acids generally is a pH of 4.0 and even decrease in order that’s the place the “ouch issue” comes from.
Identical to train, if you wish to obtain outcomes to your physique and general well being and longevity, you DO have to create some discomfort. However for the pores and skin, I like to depart these for retinol, prescription retinoids, at-home peels, my 7-day skin challenge {and professional} therapies like micro needling, dermaplaning, lasers (like the Moxi laser I had done on my own skin) and chemical peels.
In case your objective is to create a smoother, even-toned texture with much less seen pores, there shall be negative effects that may compromise the pores and skin barrier and trigger irritation, however placing your pores and skin in a state of elevated sensitivity each single morning with the usage of a low pH vitamin C serum? Nope. I’m completely not a fan of that.
(For those who really feel like your barrier is broken, here’s how to fix it.)
How Efficient is THD Ascorbate for Lowering Brown Spots and Hyperpigmentation?
I used to be launched to Tetrahexyldecyl Ascorbate again in 2004 whereas in search of higher options for my shoppers fighting hyperpigmentation from solar, hormones, and breakouts. Initially, I offered a 2% Hydroquinone product to focus on pigmentation which continues to be identified to be very efficient, however throughout a beauty chemistry class at UCLA, I realized about THD’s promising results on melanin manufacturing. Except for it not being irritating, what stood out was its stability—it was efficient all the way down to the final drop, guaranteeing you may get probably the most out of their funding.
This sparked my journey with THD, and inside two years, I developed a vitamin C serum utilizing this ingredient. The outcomes throughout testing have been unimaginable, and after I launched it and beneficial it to shoppers, over the course of weeks and months their solar spots, brown spots and marks from breakouts improved a lot sooner. I phased out the hydroquinone serum in favor of utilizing THD Ascorbate, which proved to me it was far simpler for pores and skin brightening.
What Proportion of THD Ascorbate Is Efficient?
It’s much less about trying on the ingredient checklist (often called the INCI checklist) and extra about the kind of product that makes use of it. As a result of THD Ascorbate requires time to penetrate the pores and skin, it’s greatest utilized in leave-on merchandise. I don’t suggest it in merchandise that rinse off the pores and skin as a result of there merely is not any time for the THD to get to work. Additionally, THD requires a lot decrease use ranges than ascorbic acid, due to its supreme capacity to penetrate into the pores and skin. Oftentimes customers prefer to see increased percentages of components, however extra just isn’t all the time extra! Pores and skin doesn’t want as a lot THD as ascorbic acid to reap its advantages. For instance, there’s a examine exhibiting the collagen-boosting results of THD at simply 0.1%. For pores and skin brightening, there are advantages seen as little as 0.5%.
Right here’s how to read an ingredient label.
Truthfully, it’s much less in regards to the INCI checklist and extra about the kind of product that makes use of it.

I don’t suggest it in merchandise that rinse off the pores and skin as a result of there merely is not any time for the THD to get to work. Additionally, THD requires a lot decrease use ranges than ascorbic acid, due to its supreme capacity to penetrate into the pores and skin. I perceive how customers prefer to see increased percentages of components, however let me inform you, extra just isn’t all the time extra. (A lot to what social media tries to inform you!) Pores and skin doesn’t want as a lot THD as ascorbic acid to reap its advantages. For instance, there’s a examine exhibiting the collagen-boosting results of THD at simply 0.1%. For pores and skin brightening, there are advantages seen as little as 0.5%.
Is There Scientific Analysis Proving How THD Can Assist Enhance Discoloration?
Behind the science: The first producer of THD has carried out a whole bunch of research on the advantages of THD, which is the way it was capable of obtain quasi-drug standing in Japan and Korea at 3% and a pair of%, respectively. Sadly, these research are usually not publicly out there, however there are peer-reviewed research on the advantages of THD in pores and skin, each alone and together with different skin-lightening components.
How Typically Ought to I Be Utilizing A Vitamin C Serum?
The advantages of utilizing a vitamin C serum is when it’s used day by day as a part of your morning routine. Not solely does it assist suppress melanin manufacturing however the usage of all kinds of vitamin C helps to guard pores and skin cells from environmental harm. It scavenges free radicals, that are unstable molecules that result in pores and skin harm and speed up pores and skin growing older. Free radicals are continually coming at us from so many various sources, together with UV gentle from the solar, ozone, smoke, and air pollution (to call a number of). All of those are additionally chargeable for a pure depletion of vitamin C in our pores and skin over time, which is why supplementing with an oral antioxidant product is so necessary.
Bonus: Vitamin C helps forestall collagen breakdown and promotes more healthy collagen manufacturing. First, it helps defend the collagen you have already got by inhibiting a gaggle 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.
When In My Routine Ought to I Be Utilizing A Vitamin C Serum?
All the time within the morning. Right here’s how I like to make use of it: after I’ve cleansed and toned my pores and skin, I’ll use two pumps of Vitamin C + E Treatment and gently press it into my pores and skin with my fingertips, actually letting it set into the pores and skin for a few minute. This offers the powerhouse components a second to do their factor earlier than I transfer on to my subsequent step.
After that, I end off with my favourite non pore-clogging Weightless Protection SPF 30, locking the whole lot in and defending my pores and skin from these pesky free radicals. It’s a easy however tremendous efficient combo that leaves my pores and skin feeling recent, nourished, and able to tackle the day!
Backside line about THD Ascorbate: It’s an ingredient that I worth rather a lot due to analysis and in contrast to fashionable components, this has endurance as a result of it’s a kind of components the place you possibly can really see the distinction which isn’t the case with plenty of components, despite the fact that they nonetheless are helpful.
Since THD is probably the most steady type of vitamin C and now thought-about to be “the gold commonplace of vitamin C”, it doesn’t want that low pH to be efficient, which is nice information for our pores and skin barrier. I hope you’ll think about making an attempt Vitamin C + E Treatment as I’ve formulated it with a pH of 5.3, making it a lot gentler on the pores and skin than most.
From my palms to your face, your pores and skin barrier will thanks!
