I’m fighting the visible aging process tooth & nail to Cosplay for decades ofbad decisions, as you’ll notice if you make it through even a couple of posts here or on my Instagram. So I’m often asked about my recommendations for the best anti-aging skincare products. My first answer will always be sunscreen, but coming in at a cthua trận second for people of all ages is an effectively formulated vitamin C serum. I’ve sầu seen a lot of people in skincare enthusiast circles recommend Timeless20% Vitamin C+E+Ferulic Acid Serum, so for the past couple of months, I’ve been putting it to the chạy thử.

First things first, though. What makesVi-Ta-Min C (specifically the L-ascorbic acid khung used in the Timeless and many other vitamin C serums) so important for anti-aging? And what makes a vitamin C serum effective sầu or ineffective?

Vitamin C Serum: The Basics

Vitamin C is one of the elite few skincare ingredients with a sizable & more or less crediblebody of researchsupportingits claimedeffects on skin. There are a number of different Vi-Ta-Min C derivativesused in cosmetics; for the rest of this post, I’m going lớn be talking specifically about L-ascorbic acid (L-AA), which is one of the most widely studied và used forms. In many cases, when a cosmetic label lists “ascorbic acid,” what’s meant is L-AA.

In some ways, L-AA is awesome. Very few other ingredients are scientifically demonstrated to deliver such heavy-duty benefits.A potent antioxidant, it has been shown todefkết thúc skin from không tính phí radical damage caused by UV exposure. While it’s no substitute for sunscreen, it can boost sunscreen’s ability khổng lồ protect your skin fromsun damage. L-ascorbic acid’s antioxidant powers can also preventthe oxidation of melanin already present in skin, resulting in clearer và more even skin tone.

Speaking of pigmentation, L-AA inhibits the production of melanin và so is used toreduce and prsự kiện hyperpigmentation. Current retìm kiếm also shows that a properly formulated L-AA hàng hóa can increase collaren synthesis, which is Vi-Ta-Min C’s key selling point in anti-aging products.

For brightening, photoprotective sầu, and anti-aging benefits, however, you can’t just take vitamin C supplements or eat lots of delicious oranges. (Though you should bởi vì that anyway, for overall health.) Very little orally consumed Vi-Ta-Min C makes it khổng lồ the skin.

You can’t just break open a Vi-Ta-Min C supplement and smear it on your face, either. Topical Vi-Ta-Min C needs lớn be formulated lớn certain specifications to penetrate skin and be effective.A concentration of 20% is optimal, and in an aqueous solution (like most serums), the pH needs to be lower than 4 for stability & lower than 3.5 for the L-AA lớn penetrate skin & work its slow magic.

(By the way,to lớn answer a very frequently asked question, these requirements instantly disqualify the Klairs Freshly Juiced Vitamin Drop serum, which has 5% L-AA và a pH of 6).

But the right concentration & pH aren’t all that matter. Much like me, L-AA needs the tư vấn ofa few friendslớn really come inlớn its own. I need my fellow Snailcast members, & L-AA needs vitamin E and ferulic acid. Vitamin E boosts the serum’s overall antioxidant defense, while ferulic acid stabilizes the solution and significantly increasesits photoprotective sầu properties.

So to lớn recap,for optimal anti-aging, skin-brightening, & photoprotectiveeffects, a water-based vitamin C serum that uses L-ascorbic acid should:

Having used the sản phẩm, I’m inclined khổng lồ agree that oily skin could find the consistency of the hàng hóa problematic, but not necessarily or terribly so. It’s up to you.

When and how to use:Useimmediately after cleansing. Dispense a few drops into lớn palm và spread in a thin layer over skin. Allow to lớn dry & absorb for at least 10 minutes before moving on to lớn the next step of your skincare routine. I use this once daily, in the evening; vitamin C’s half-life in skin is four days, quite a long time, & there’s a limit to lớn how much Vi-Ta-Min C skin can retain, so I don’t see the need khổng lồ apply twice a day, as much of the sản phẩm will be wasted. Either morning or evening use are fine.

Timeless CEF Serum hits all the main points. Its pH is low enough và then some. The concentration is the maximum effective sầu according to lớn current research. And the L-AA here is accompanied by its good friends Vi-Ta-Min E và ferulic acid. Well done, Timeless. I don’t see anything to lớn complain about in the ingredients, either, as long as you personally aren’t reactive lớn any of them.


Timeless 20% C+E+Ferulic Acid Serum is a thin liquid that should be colorless when you first open it, denoting the freshness of the sản phẩm. As L-AA oxidizes, serums turn progressively darker, from clear khổng lồ yellow into lớn brown or red. I normally discontinue use anytime the sản phẩm becomes darker than the cheap champagne that has given me many a New Year’s Day hangover. Oxidized Vi-Ta-Min C is ineffective sầu at best và possibly damaging at worst.

The stabilizing ingredients in the Timeless CEF Serum appear to lớn bởi their job just as expected, however. The company guarantees the serum’s freshness for three months. Two months after opening the sản phẩm, mine is still almost colorless.

I’m impressed by the relative longevity of the CEF Serum.

That longevity is even more impressive sầu considering the suboptimal packaging. Dropper bottles just aren’t great, especially for antioxidant-heavy products, since the regular exposure to air accelerates the product’s degradation. The Timeless bottle is dark, at least. And again, the sản phẩm appears to lớn be lasting just fine–at this rate, I’ll be able lớn finish the entire bottle without moving into the yellow.

The Timeless CEF Serum doesn’t feel great going on.Thanks to lớn the Vi-Ta-Min E, the serum has an unpleasantly oily feel, but it’s draggy at the same time, not the easiest lớn spread on bare skin. It also smells faintly of hot dog water due to lớn the ferulic acid. Kind of a Catch-22: both those ingredients make the sản phẩm work better but smell and feel worse.

When I first started using the sản phẩm, I worried that its greasy finish would interfere with the rest of my skincare routine. Luckily, that turned out lớn not be a problem after all. Given 10 minutes or so, the serum does fully sink in lớn my skin, leaving it looking và feeling bare again. The smell also fades after a little while. So although the CEF Serum is initially a little unpleasant to lớn apply, its consistency and smell are not deal-breakers after all.

As for results, those can be hard lớn judge with a sản phẩm lượt thích this. The collagen-building effects of vitamin C can take up to a year khổng lồ become visible, and the spot-brightening results need time lớn appear, too. Over the couple of months that I used this hàng hóa, I wasn’t looking so much for dramatic new results as I was looking to lớn confirm a continuation of the results I’ve been getting from long-term use of the popular (but not ideal) OST C20 vitamin C serum.

Essentially, I wanted to lớn see if I would start khổng lồ thua trận any of the progress I’d made with Ctrăng tròn. If dark spots or other signs of sun damage showed up, or if my skin began to đại bại the firmness or even tone I’ve sầu clawed bachồng from the grip of Time, I would know that discontinuing Ctrăng tròn use had resulted in me losing something that the Timeless CEF was failing khổng lồ replace.


Turns out, I lost nothing. The Timeless is at least as effective as Cđôi mươi at preventing new signs of sun damage and visible collaren loss.Based on its objectively better formulation, I expect it to be a better investment over the long term as well. The fact that it seems lớn stay good for much longer than the Cđôi mươi makes it a better piông chồng financially, too.

My main caution to lớn people wanting to lớn try this sản phẩm is khổng lồ patch thử nghiệm it (as you should be doing anyway!). The very low pH of the Timeless CEF may cause it khổng lồ sting or irritate your skin, especially the first few times you use it. If that’s the case,waiting after cleansing until skin is fully dry và less absorptive–as tretinoin users are recommended lớn vì with their prescriptions–can help.

Conclusion: I didn’t see any rapid, dramatic improvements with this product, but then again, I didn’t expect to. This isn’t my first time with a vitamin C product, so my days of amazement at the powers of Vi-Ta-Min C are long behind me. What I hoped to lớn see was equivalent or better effectiveness compared khổng lồ the other vitamin C serums I’ve used. Timeless 20% Vitamin C+E+Ferulic Acid Serum met my expectations there và exceeded my expectations for pH and overall formulation. I’m satisfied with the sản phẩm & won’t have a problem finishing the bottle before moving on to the next candidate.
