You’re not alone buddy. I’m a 30yo male as well and I care for my skin with retin a at night, vitamin c, mineral sunscreen and niacinamide moisturizer during the day. I came across her channel while searching for mineral sunscreens and stay for the skincare videos.

[@cassiebrown9786]

From what I've read THD does convert into Ascorbic Acid. I prefer THD over the surface C's. I like that THD is less irritating and is a stable C. I suppose its a matter of preference. I know this, my skin looks less sun damaged from using a form of C. Hugs, Cassie

[@mrsklet]

Wow Angie. You sure stirred up a hornets nest on this subject 😂 I think vitamin C is a very personal choice. I tried the timeless and unfortunately I didn’t care for it. I now use the truth treatment C balm and so far so good. I know it’s very expensive but it lasts a very very long time. On a sidenote I think you should give some of these products a try before discounting them. Thanks for all you do. I really enjoy your videos and appreciate your time and efforts into all that you do. You one of my favs💗

[@sherrig.7870]

Truth Treatments is my holy grail, also you can find discount codes to get almost $50 off. Used to use Timeless & it did absolutely nothing so I learned my lesson. You should probably listen to one of Dr Benjamin Fuchs videos because he explains TT in complete detail. The Serum is 80% & the balm is 70% potency with no extra fillers, just the delivery system. Transformed my skin. Sometimes paying a bit more for quality skincare is worth it in the long run.

[@RedBilyeu]

I 100% agree. Tried Timeless with no results. I love TT and iS clinical vitamin C.

I need to thank you for all you’ve taught me over time. I saved a lot of money and through you’re counciling, my skin is so much nicer than a year ago. We’re lucky to have you!

[@MakeupForMatureSkin]

Hi Angie I totally respect your opinion. I've been using vitamin C serum for several years. I first tried timeless and it did absolutely nothing for my skin. I saw no changes at all. Then I tried drunk elephant I saw some changes but stopped using it for other reasons and moved on to the skin Deva. I enjoyed skin deva for many years and saw some changes in my skin. I tested Mae love again I saw absolutely nothing. I heard a lot of hype over the Truth Treatments and thought it was all hype until I tried it. It's the first vitamin c serum that I've noticed a huge change in my skin. I have a glow, my sun damage has faded so much more and the biggest win for me is the change I've seen in my sebaceous hyperplasia has gotten much flatter since using this. There is no scientific proof that vitamin c will help with my SH but that's what I've noticed on my skin since using this and a few of my subscribers have shared the same. So I understand on paper or on charts you can compare and say this is better than that but at the end of the day it's what's best for your (my) skin. I've use skincare products that were scientifically "proven" to work and when I tried them they did nothing for my skin. Many of my subscribers are using TT and have told me the same. So again I totally respect your opinion but wanted to share mine so anyone watching this can have another opinion especially since I've actually been using it for several months now. Thanks so much for sharing your thoughts respectfully, Anne❤️

[@tamgonzalez2548]

I agree ! Don't care for Timeless or Maelove Vit C. Change to Dr. BRENNER and I love it.

[@lindacarol41]

Gotta side with Ben Fuchs on this one!

[@lupeluis7041]

Annie you made me wanna try it but the price. Its totally robbery. I am glad its working for you.

[@ManUntdForever]

Personally, I don't understand the demonization of medical grade skincare I always find online. Yes, it's expensive, no one is arguing otherwise, but I've also found that I need far less when I use medical grade products and therefore the products last me for months. Medical grade skincare is the only type of skincare that has ever given me substantial results.

[@sbar114]

I agree Anne. I wouldn't have believed my skin would change so dramatically just by trying a different type of vitamin c. TT has made my skin look it's best hands down.

[@ChristineByerEsthetician]

It’s weird though over the years I see clients on L ascorbic who develop irritated cheeks and sensitivities as L ascorbic is still an acid. I find VBOSC/THD works best for brightening. I remember when Dermalogica brought out this form of vitamin C about 15 years ago when I was a new ish Esthetician.

[@leat.2147]

Christine Byer, Licensed Esthetician What is vbosc?

[@claudiaglows]

Though I agree with you that it has to be turned into ascorbic acid to be active, I actually love THD. On my skin it is far less irritating than straight up ascorbic acid. I use TruthTreatments and there products are quite amazing It is crazy expensive, yes... but they tiny bottle of vitamin C for $49 actually lasts me several months. There c balm is also absolutely incredible and I have seen a big difference in my skin. The serum is 80% THD, the balm 70 % I respect your opinion though and really enjoyed the video

[@elenaAGN]

Same here! This serum is the only one that made a difference in my skin.

[@SkinBeautifulRX]

Agree Claudia! For people who have spent years and countless $$ trying different C serums and their skin cannot/will not tolerate it, THD is a game changer for them. And many just prefer it over L-ascorbic. One opinion of many, and that’s why skincare needs to be customized.

[@claudiaglows]

[@lorainemcgillivray77]

Hi Angie oh the "medical grade" skincare debacle drives me insane. I was a Registered Nurse for around 20 years including several in the Maxillofacial (head and neck) Unit. Medical grade skincare is on prescription ONLY and is either ingredients not available over the counter or higher percentages of ingredients only available on prescription from a DOCTOR. Hugely expensive 10% niacinamide is the same thing as cheap 10% niacinamide for example. For me tretinoin, hydroquinone and high strength azelaic acid are medical grade skincare - not some fancy peptide serum. As for vitamin c I agree that if possible L ascorbic acid is the way to go, however I'm one of those who can't tolerate it on their skin. I have mild type one rosacea and eczema so anything really acidic doesn't suit me including vit c, glycolic etc. The only acid I can actually use is azelaic acid. i get my antioxidants from green tea, niacinamide, licorice, tretinoin etc etc etc. I have managed to use some of the derivatives without the burning/stinging I get with the low ph of the l ascorbic acid. I would never pay $200 for a derivative (or to be honest any skincare item), but there is another product I have seen with this ingredient - Garden of Wisdom sells a C deep serum which in the UK is £18 (I can't imagine it's more than $25). i hope that helps anyone who has been considering this pricey item. Some of the youtube beauty community seem to push products outwith the reach of most people, which is very irresponsible. More often than not it's about brand names and/or products that are "gifted" to them. Best wishes.

[@juliechambers7652]

I'm an RN too, and I completely agree! I think medical grade is just a marketing ploy!

[@LuluLu2022]

I feel you Loraine however the TT Vitamin C Balm is The Bomb!!! I realize Angie is talking about the serum which i have also used and may try again. I purchase and will continue to buy the 15ml size and it will last for months! I use it at night and only need a little pea size. It literally has 4 ingredients with the first one being Vitamin C in THD. I also cant use the Ascorbic Acid as it really irritates my skin. My opinion, never say never and try TT sample size for $50. Thanks Angie for all of your research!!!

I wanted to share my experience with the Truth Treatments Serum, I know it's about 70% THD and it's non irritating in my opinion. There are 20-25% coupons that I always use when buying it. One bottle lasts me about 10 months, it's super concentrated so I mix 3 drops with a HA serum every morning. It's an amazing cocktail and I feel like it's the only vitamin C serum that made a big difference with my hyperpigmentation. I previously used the Drunk Elephant one but TT is another level!

[@ksmasura6165]

Agree! I love TT. No irritation and it’s the first Vit C to make a difference in my skin. Texture, pigment and brightness.

[@mommybear8672]

Having used Timeless for years and just recently started using TT THD for a few weeks now, no comparison..the difference is huge. I agree with you, you have to look at the % and the length of time it lasts..the small size, which I got on sale (they seem to run specials frequently) will last me a very long time. Kinda hooked.😅

[@michelehiggins8836]

I think I disagree with Angie this time Timeless is not the best and has not done anything for my dark spots This TT is a wonderful and you said it right now a little goes a long way

[@piperlucille]

Mommy Bear I have been using Timeless and I haven’t seen any different at all. I looked at the TT site and it 49 bucks. Is this the right one? That doesn’t seem expensive to me when it lasts for so long.

[@nevertooold6498]

I am also seeing a difference with the TT vit C and I've only been using it for 3 weeks. The only other product that helped with brightening was the Peter thomas Roth vit C and he uses THD too, but 20%. It didn't really help my spots and melasma though. I am starting to see some improvement on spots and melasma with the TT, so I will, of course, continue and I will also start the retinol now. Fingers crossed!

The prob is not everyone is like you. Angie should absolutely warn that Vit C can be very irritating & one should be careful mixing acids. Not everyone can tolerate Vit C use every day. I burned my face badly following her routine & it took months to heal.

[@Weaver1202]

swineinny1 It’s not Angies responsibility to do research for everyone’s different skin type. Knowing Vitamin C is an “acid”, it’s pretty common knowledge to make sure it’s right for YOUR skin. She shares what works for her- any “actives” are completely on you to decide if it’s right for YOU. Can’t put any blame on her. In fact, just about ANY product can be irritating, depending on one’s unique skin issues.

[@leahvincerouse]

So funny!!! I was just watching another KZbinr that I follow and literally at the same time she was talking about the Tetrahexyldecl ascorbate. And how it’s the best.

[@apleat1]

Angie, your videos are so well made and thought out. I have been saving so much since I've been following you and my skin has never been better. I like how methodical you are and you base your opinions on science. Well done!

[@SteffanieEntralgo]

You're not entirely accurate. This is straight from my friend who is a biochemist for cosme-ceutical companies... And I've used the Timeless C Serum, Drunk Elephant, Skin Ceuticals, Mad Hippie, Ordinary, Paula's Choice, Maelove, Ole Henricksen (2 versions, truth serum and banana bright) and most recently, Beautycounter's. Tetrahexyldecyl ascorbate is a more stable, oxidation-resistant form of vitamin C, and is therefore more powerful at lower concentrations than ascorbic acid! When people ask about the “percent” of vitamin C, they often think higher is better; not the case with this form. In fact, high concentrations of the parent form, L-Ascorbic Acid, have a huge trade-off: they can be irritating to the skin. Tetrahexyldecyl ascorbate is effective at lower concentrations, and less potential for irritation. It’s lipid-soluble, so its effects are deeper and longer-lasting in the skin, which is made of lipids! It actually penetrates the skin, THEN converts to L-ascorbic acid, a much better delivery system. Because of this, it can do 3 things: 1. Serves as an antioxidant (this helps prevent wrinkles/aging) … camu camu and turmeric enhance this activity 2. Fades discoloration by normalizing your skin’s production of melanin. 3. Boosts collagen production - most vitamin C serums with ascorbic acid do the bulk of their work as an antioxidant. Tetrahexyldecyl ascorbate can also boost collagen production because it penetrates more deeply. Bis glyceryl ascorbate is ascorbic acid bound to glycerine, which adds moisture-retention power to the antioxidant properties of vitamin C. Many vitamin C serums, especially higher % AA, can be irritating or cause problems for dry skin. Bisglyceryl ascorbate should help make this serum appropriate for all skin types, including dry!

[@carolinewilhite6362]

Great info! Thank you for sharing!

[@SteffanieEntralgo]

@Dee LOL Yes, vitamin c can be an all or nothing product. Either you can tell it's working or it's wasting time - I feel. Personally, my top three favorites have been the Drunk Elephant C Firma (however, this is in an oil base and sometimes I can't use it (like summertime...too heavy) also Drunk Elephant oxidizes REALLY quick for me. Next, I like the new Ole Henricksen Banana Bright C Serum... but honestly, I'm not sure if it's the Vitamin C or the fact that they included PHA in the formula to help exfoliate and brighten, so hmmm. And finally, Beautycounter's. I've really enjoyed the texture and results from this formula - so much so, that I find myself feeling more comfortable with a Tinted Moisturizer over a foundation lately (which, if you watch my channel... I'm a big foundation wearer). I felt NO RESULTS from Timeless, Maelove, Mad Hippie and the Glossier one. I saw results with Skin Ceuticals but nothing worth that price tag. Hope that helps!

@Dee Hi, I was reading through comments and saw yours and I wanted to give you some information, or really my opinion. Quite frankly I have tried cheap skincare and I have used medical grade and I have seen the difference in results. My skin looks way better when I am using medical grade skincare products. Also, I have used all forms of vitamin c, and the tetrahexyldecyl ascorbate has been done the most for me and i have seen the best results with it as well, that is not to say that ascorbic acid has not done good things for me, but just that serums with tetrahexyldecyl ascorbate have been better for my skin. Also, I 100% love truth treatments, it is that good. I live in the desert so I don't really use the hyaluronic acid often, but it is wonderful. I have most of the truth treatment products and they are awesome. I also love revision skincare vitamin c. I am not sure how anyone can review a product they have never used.

I’ve used L Ascorbic Acid for decades including Timeless. I have sensitive rosacea skin. It was always slightly irritating. I tried the TruthTreatments THD and my skin never has looked this good. No irritation- no worries about mixing with my other actives- no oxidizing-my skin glows- is less reactive and is more hydrated. I use the pea size recommended with a mineral mist so it spreads easily. I tried other THD but unfortunately I broke out from other ingredients in the serum. I purchased at 30% off and the bottle lasted one year. More than my other Vitamin C’s but not by much considering the results. Of course anecdotal but I don’t regret spending money on this. One thing I’ve learned on my skin journey is to not listen to any gurus- our skin reacts differently and has different needs.

emma /a TT is the best out there for all their products!... love them!!!!

[@esperanzawenceslaomoral7237]

Totally agree with you. The 5 ml TT bottle lasted 3 months when I bought it so it's a good investment. You pay a lot for the big bottle but it can last you ages since you only use 2 to 3 drops mixed with a mist. No irritation and you can use It around your eyes. The only drawback is that you have to mix it with their mist..which makes the final product more expensive as you run out of it much more quickly than the serum itself.

[@lindamarocco4583]

Thank you for diving deep into this issue, Angie! I've tried so hard to love l-ascorbic Vit C (made my way through various percentages and price points), but my skin just doesn't.

Have been using PTR's Potent-C serum, but am about to move on to Ghost Democracy's Lightbulb Vit C serum, which is far more affordable. Keep doing what you're doing!!

[@shannonandrews2649]

I love the truth vitamin c. I saw a huge difference in my skin. Also medical grade goes much deeper in the skin and has a ton of science behind it. Obviously you look beautiful so keep using what is best for you😘😘

[@pancake664]

Angie, you make a good case for L-Ascorbic Acid and I do agree with some of the points you raised. However........ First off, you can't know whether a product works or doesn't work without trying it for an appropriate length of time. You have therefore not approached us with a balanced, well informed opinion. You are purely guessing that it may not work but can't actually say for sure. The proof especially with skincare is in the trying; that's the only way to know for sure. Ben Fuchs is a chemist, compound formulator, nutritionist and a very well respected scientist with over 30 years of experience under his belt. I've watched quite a few of his videos and I'm inclined to believe he knows what he's talking about. His products are expensive but the results are phenomenal! Regarding conversion of THD; retinol converts into retinoic acid so why would THD not convert into ascorbic acid with consistent use. As you said ascorbic acid is very unstable and can be very irritating too. I had zero luck with the ones I've tried. If you have not, please watch a few Ben Fuchs videos and decide for yourself whether you think his products will be a crap shoot! I have enormous respect for Kylie and how well she's done but I'm not sure she's spent much time in the laboratory!

Hi Angie-Thanks for the video! I’ve been using medical grade skincare for a long time and have never seen the results I’ve received with TT, I use all their products except for the cleanser. It’s definitely not a crap shoot and you should really try their products before you give an informed opinion. You only need a very small amount and if you want to see results sometimes you have to pay for quality. Have you watched any of the YT videos with the creator Ben Fuchs? Trust me it’s not a waste of money and I will never go back to L-ascorbic acid...

Okay but for the Kylie Skin, the preservative is the third ingredient which is phenoxyethanol and used at 1% and below. So realistically, how effective are the ingredients listed after the THD and glycerin?

[@pamelacossey8604]

I use the truth systems C balm And can honestly say it is very helpful for hyperpigmentation. I ordered from a website with 25%off and bought the smaller size--it only takes a tiny amount . The problem with other ascorbic based serums I've tried is the smell and the addition of irritating citrus oils and other fragrances. Can't go wrong with Paula's Choice--have never had a reaction to anything in this line

Hi there luv your reiviews I think they are very educational and informative. I did use the timeless vitamin c for 2 months and I have to say I wanted to luv it but I didnt see any brightening on my skin. So then I went with the truth treatment systems there vitamin c serum, there vitamin c balm and retinol gel and I must say in just 2 weeks I notice alot of brightening in my skin that I decided to stay with that brand. I know its pricey ladies but I think its worth every penny. And the best part it only has a few ingredients only what your skin needs, thats awesome. And besides you use a pea size of any of The Truth Treatment Systems products and it goes a long way beacause its very potent. So sorry that the timeless brand didnt do what I hace hoped for, but I guess it may do wonders on some people but on others it just wont. Nevertheless this was a wonderful review thank you for putting it out there for us gals. God Bless You.

I agree that L ascorbic is the only form worth using. Well done I love the research and your summary of the benefits. I also find it important that The half-life and skin lasts 4 days so the layering doesn't have to be daily especially with vitamin c product because they don't layer that well with many others that we want to include. Great video as always on a subject that people don't understand

Angie I wish you would try THD. I was ride or die Ascorbic Acid for YEARS. I'm a formulator and DIYed my own Ascorbic Acid serum for 2 years. For the past year and a half I've gone back to Timeless/Dr Brenner out of sheer laziness (I love formulating but DIYing Vitamin C doesn't exactly spark joy so I focus my formulation efforts on other products.) Suffice it to say, I've been using Ascorbic Acid every single day for 3.5 years. Recently I started using THD and I have noticed a positive difference in my skin.. just because research doesn't exist yet doesn't mean it won't in the future. The "no research = no efficacy" outlook is an oversimplification and also seems a bit reductionist to me. Ascorbic Acid wasn't researched until relatively recently..does that mean it wasn't effective before Dr. Pinnell and his team researched it? No. It just means the research didn't exist yet..

[@lupeluis7041]

Can you tell me why it warrants such a pricepoint? I cringe tho it is recommended by several youtubers that seem honest.

[@e.a.4926]

@@lupeluis7041 it doesn't.. The Ordinary Ascorbyl Tetraisopalmitate is 20% THD and it's $17. The Truth Treatment Systems products are expensive because they are "medical grade" and supposedly use patented penetration/bioavailability technologies. As a raw ingredient, it's true that THD is more expensive than Ascorbic Acid. It's because it's more complicated to manufacture since a palmitate group is added to the Ascorbic Acid chemical structure. That's what makes it oil soluble. Oil solubility is what makes it have better bioavailability in the skin (our skin is made up of mostly lipids)

[@AngieHotandFlashy]

Hi Emma, I agree that no research doesn't mean no efficacy but given 2 products, one with a pile of independent research and one with only company research I give more weight to the one with more research. Also, curious if you mixed your own THD serum or if you bought one? xo ~a.

[@belmabee5646]

I agree with you i love my TT c balm and see a big difference in my skin ❤️❤️❤️

[@e.a.4926]

@@AngieHotandFlashy thank you for responding and your perspective makes perfect sense. I just like to be a little more experimental in my approach to skincare, that's why I'm willing to take my chances with THD and other less researched ingredients. I'm actually using both Ascorbic Acid and THD right now. I'm using the Truth Treatment 5% Retinol Gel, alternating nights with Tretinoin. The 5% Retinol Gel contains 20% THD. But I am working on a THD formulation, I'm actually waiting for the ingredients to be delivered. It's going to be a THD "balm" meant to dupe the TTS Transdermal C Balm. It's mostly THD with Squalane (a penetration enhancer) and some thickeners (Cetyl Alcohol, Stearic Acid, Emulsifying Wax NF.) 🙂

Arlene Madison This is a great oil if you have oily skin, which needs linoleic oils, however dry skin needs a different type of oil that is more oleic than linoleic

[@skinsciencebymira]

English Rose not really true evidence wise. Linoelic acid actually helps skin barrier integrity, helps replace and organize skin barrier lipids, and improves hydration as a result while oleic acid has been shown to disrupt the skin barrier and increase water loss from the skin. Dry skin benefits from free fatty acids but particularly LA plus ceramides and cholesterol as well as an occlusive moisturizer and a low PH cream cleanser.
