I've been using the C+ Correcting Complex for awhile now and absolutely love it! Worth every $$

I love Revision Skincare C+ and have been surprised I don't see it mentioned in more videos. I have sensitive, dry skin and have not had any issues. I have noticed my hyperpigmentation has slowly cleared while using this product. I highly recommend!

Your skin is flawless. Thank you for this video.

Last year I used a popular 20% l-ascorbic acid product for a few months and my skin became very sensitive. I stopped using it, but it took a long time to get my skin back to normal. Now. I only use products with THD. I have used the Paula's Choice moisturizer you mentioned. It's very nice.

Same! For about 20 years I tried different L Ascorbic acid serums with E and ferulic acid. I never enjoyed any of them but used them because of the scientific evidence that L Ascorbic acid stimulates collagen production in the skin.

I realized that the Vanicream one is better for me because at night I use retinol and if I use the other vitamin C’s in the AM that have a ton of other ingredients like lactic acid it will 🔥 burn my skin. This product is great for sensitive skin.

Thank you for explaining skin care that is understandable and useful 😊

Hi Dr. Jenny. You always keep it real 💗 !!!

I use the Vanicream Vit C and love it. great for my sensitive skin.

Does it help with dark spots?

You are so so gorgeous omg, I will def try out these products!!

Great video, and super informative! For really dehydrated/sensitive skin, especially in winter, I like Sanitas Vita C Serum. It's oil-based but a few drops (you don't need much) applied to damp skin and it absorbs within minutes. DRMTLGY also makes a great Vitamin C based moisturizer, their C5 is fantastic. Sanitas makes a 15% THD Serum that's also good and affordable. I've gone through several bottles of it.

This is a great video! Thanks a lot!

you are GLOWING!

Thank you! Very well explained !

Loving the Vanicream vitamin C. Travels well, light weight and moisturizing. I've seen Amazon offer buy two get 40% off. Ordering more right now! I may try the Skin Better or Revison products.

Thank you for this info very helpful 🙏

I just bought the PTR Potent C serum. I love it so far.

I have been using the perricone md ccc for several months and I have noticed lightening of my dark spots. I will say that perricone md often has sales especially around holidays. Zulilly often has these products as well if you want to try to see if it works for you before paying full price. Lastly, I have combo skin and unlike other formulas, I don’t have an issue with this product; doesn’t make me greasy nor doesn’t cause me to have acne.

What’s the THD percentage, pls?

I love the Peter Thomas Roth Vitamin C. Currently trying the Skin Better Science one and like it but will likely go back to the PTR. I like that most THD vitamin C come in a pump rather than a dropper which I hate. While these are expensive, I could never finish a L-ascorbic vitamin C before it oxidized so factoring that in many of these are cheaper than the SC one.

I’m using PTR. Agree about the packaging. It’s ridiculous that so many serums come in dropper bottles. I just hate the odor of the PTR so am hoping to find another 20% THD serum under $100 that does not have this odor.

Excellent content thank you💐

Can you make a video talking about layering your serums? For example, if a person have hormonal imbalance, acne scars, dry skin, and wants to fight anti-aging. How do one layer their serums? And which should be layer first?? I always get confused. For example, morning I want to hydrate and tackle my acne scar but I'm always unsure which chemicals will work with one another so I can get the best result for my skin. AM and PM.

Dear doctor, PLEASE make a video about what you think of face muscle exercises that are so trendy today. Thank you.

Hi Dr.Liu, I know you had previously highly recommended as a favorite Glytone Age Defying Vitamin C, which has THD Ascorbate as well. I see that this product did not make the list this time. Do you just like these products more at this time?

Do you also recommend the new Skinbetter Alto Advanced Defense and Repair? Can you please advise, which is better for acne prone and rosacea skin?

Finally THD getting some attention! Every active product in my a.m. and p.m. routines contains an effective amount of a substance that has been proven to stimulate collagen in the skin EXCEPT my THD vitamin c. I’m willing to make one exception because I love how THD products make my skin feel. I’m alternating between the Peter Thomas Roth Potent C and the Vanicream C. Now that I have found THD, I’m looking for more THD products to try. Even when on sale for about $70 I feel the Peter Thomas Roth serum is not at a reasonable price. Plus the smell is terrible and I’m hoping another company will be able to formulate with THD in a way that doesn’t cause this odor.

Thanks for your review! I see that the Vanicream THD serum has a best by after opening date of six months. Are any of the other products that you reviewed longer lasting? Edit: Ascorbic Acid tears my facial skin up! LRP has a 5% pure Vitamin C that is the least irritating to my hyper sensitive skin. It is called Pure Vitamin C Cream with Neurosensine. Very nice product to wear. :)

It was helpful. As I need to incorporate Vitamin C into my skincare routine. Can you please review depology

Yes I'm not sure if that would be my case about rosea, I went to the regular Dr and that day was cold and told me I had I need rosea cream but it was not a skin doctor, ? Not sure, next time I'll ask a dermatologist

Great info. Tks for sharing on THd. Is drntlgy c5 cream good? Appreciate your thoughts

Which is better the alto defense serum or the new one alto advanced defense and repair serum?

Omg I use vanic cream the cleanser, moisturizer,SPF, vitamin c which is my favorite and the way it makes my skin look and feel better and that shine and smooth feeling it's a great product it self just fyi for any one who wants more opinion.but I learn about vitamin c couple months ago from a dermatologist on utube I have 2 i watch so far and very on point what's in the things you need and use in your products

Hello- I was curious if you would recommend Vanicream Vitamin C over La Roche Posay or vice versa?

I see there's green tea in the Skinbetter Alto Defense and i'm allergic to it. What a bummer 😢 I've used 2 bottles of Skinceuticals now and they oxidized real quick.

this video just came across my tl. if i could get an answer, since ethyl ascorbic acid is both water and lipid soluble, is the combination of eaa with thd still absorbs as quick? my serum contains both eaa and thd

Can this type of Vitamin C be used with peptides like Argireline and if so how would be layered?

Any thoughts on Dr Idriss’ vitamin C moisturizer?

Hi Jenny love your videos just wanted to know as a youtuber what benefits would you want from a thumbnail designer.

Hi just found your channel!! Would like to say that Truth Treatment Systems makes an amazing THD ascorbate serum and a C balm. High concentration too I believe they claim up to 70% but I may be wrong on that. Very expensive but like no other

My favorite is Covey Vitamin C Serum

I used several L ascorbic products and it's such a pain because it expires quickly.

What do you think about Paula’s choice 25% THD 25% Vitamin C + Glutathione Clinical Serum? Also Sunday Riley 15% THD CEO serum?

Hello Dr,is melano cc good,and does it has THD vitamin c in it ???

Can I use this with the ordinary buffet?

I stumbled upon The Ordinary Ascorbyl Tetraisopalmitate Solution 20% in Vitamin F, and I think its the unpatented version of THD? I just ordered it bc its 20% and only $20! I was looking at the Peter Thomas Roth and it was really hard to make that jump to $105. I wanted something for those days where I can't handle the burn of ascorbic acid, even though it works amazing for brightening. Can you tell us all something about The Ordinary version of THD? The upside of THD seems to be that it can be mixed w copper peptides, and tretinoin...am I correct? That's why I ordered it, bc I could use it both am and pm and add to moisturizers I like...I hope.

Thank you ❤️

I was wondering the same. The Ordinary lists Tetrahexyldecyl Ascorbate as a “key ingredient” in their product “Ascorbyl Tetraisopalmitate Solution 20% in Vitamin F.” I am really confused why they wouldn’t market it as THD (the name most of us know it by) if that’s what it is, and similarly why they would claim it contains THD if it doesn’t. :-/

Dr Liu, have you tried Dr Ci Labo's super white 377VC serum? it's a Japanese brand very popular in china, and it’s one of the best serums I have used for anti-pigmentation, it has an ingredient called 377 which I haven't heard anyone talk about on KZread, could you do a video explaining what it does?love your content, 加油❤

Is it safe to use THD ascorbate at the same time as tretinoin (both at night)? Being that it's more stable, would it still give the benefits?
