Skincare routine for glowing, clear skin: - Start with a glass of water on an empty stomach. - Cleanse face with besan powder and rose water, then pat dry. - Use liiittleextra rice berry vitamin c face serum and apply aloe vera gel as moisturizer. - At night, apply milk and turmeric mix on face, then wash off and use toner and aloe vera gel. - Have greens, fruits, nuts, seeds, and exercise 4-5 times a week or practice yoga.
So delighted to give my feedback. It is 15 days and I'm already seeing improved glow on my face with the regular use of rice berry vitamin C face serum.
Hi! I’m currently using the Cerave and it hasn’t bothered my rosacea one bit. I like the texture and the way it’s making my skin look and feel. I also started using the newest Vanicream lotion and must say, I’m loving it. Keeping my skincare routine simple and my skin is thanking me for it.
I’ve used the Vanicream three times a week for nearly a year with no problems. I have very dry, extremely sensitive, older skin. I purchased, but have yet to try, the CeraVe, because of all the positive data regarding l-ascorbic acid. If I tolerate it well, I plan to try alternating them during the week, thereby getting C every day. I’ve never understood why, but my skin has something against using the same products daily. The derms I’ve consulted don’t get it either, but they have verified that it’s true. It makes my life more complicated, but the effort is worthwhile to avoid the feeling of burning skin.
Vanicream is cruelty-free which is a criteria for me. I use several Vanicream products, including their vitamin C, and I am glad discovered this reliable brand.
Cerave has specifically addressed that apparently by stating on the product details the following: “Color might change to amber overtime; this does not effect product quality of efficacy” Not sure what the reasoning is for this change but allegedly they state there’s no difference in quality which I wonder what facts back that statement up besides just trusting them 🤔 and no explanation as to why the amber color is appearing in the first place if it has nothing to do with oxidizing the funny part is they never say it doesn’t mean it’s not oxidized just that quality is the same but that could be towards any ingredients it’s not specifying either
I like the Vanicream vitamin C because it doesn’t irritate my skin since I’m using retinol. Other vitamin c’s have too many other ingredients like acids for exfoliation.
Great video! I have very oily acne prone and sensitive aging skin. I use tret 0.025% four nights a week. I'm able to tolerate a salicylic acid face wash once or twice a week. I cannot use any form of a sportic acid. My skin has been fine with the vana cream vitamin C. I've only been using it for a few weeks so not sure of results, but I use it like a moisturizer in the morning. It doesn't make me more oily
Thank you so much for making this video! I've been trying to make the skinceuticles work for me for years since people say it's less likely to cause irritation than other l'ascorbic acid products and supposed to be the most effective, but it has always caused so much irritation for me even when using a few times a week. I've found it's more irritating than tretinoin. High hopes for this CeraVe one will be both effective and less irritating!
L-AA will ABSOLUTELY sensitize you if you are prone to it, I don't care what they do to their formula. The reason for this is because pure L-AA serums have to be maintained at a low pH, and not everyone's skin responds well to that. So acidic is acidic, it doesn't matter how many soothing ingredients they add to the formula. I personally can't use it, and I certainly wouldn't pay Skinceuticals $180 to make my face red and irritated. Maelove was the worst for me because of all the extra citrus extracts they put in it, no thank you.
I like create but I do notice it oxidizes very quickly which just leads me to believe its not getting into the skin and doing anything so I don't think its worth It and as for the vanicream I like it because it adds more hydration to the skin and ceramides so if the vitamin c doesn't do anything i am at least getting extra hydration and ceramides.
Cerave always has the 3 ceramides in everything they make. Its in their name. Cera(ceramide) Ve.. If you visit their website they can send you 2 samples : )
I have gotten away from Vitamin C serums after using Skinceuticals for years. It became so expensive and I started to wonder how much I was benefitting. I use Tazarotene 0.1% almost nightly and have tried to keep my routine very simple but maybe I should try one of these.
A BIG NO on the CeraVe serum! Gave me an awful chemical burn. Kept burning after I triple-washed it off and even for 10 days following it! I couldn’t use any face products except for Vaseline because my face was so very sensitive from the serum. Bad stuff. And my skin is normal, not dry. I would definitely try the Vanicream because their product line was developed for cancer patients under treatment who had extremely sensitive skin. I love the whole line. Their Daily Facial Moisturizer for Sensitive Skin is wonderful. The vitamin C product I’ve used for a long time is Timeless 20% Vitamin C, Ferulic Acid & Vitamin E Serum. It gives me no trouble at all. They have a 10% formula if you’re just starting out with vitamin C.
Thanks Dr Lou 💕☀️!! I’ve been unlucky with L-asc, have tried many derivatives too … this seems like a great way to try again. Huge Vanicream fan too. Thank you 💖💖💖
I actually just purchased the Vamicream Vitamin C, i have rosacea and I read this was the best form of vitamin c for that skin condition. I also purchased the Paula's Choice super antioxidant serum which has THD vitamin C in it, is this enough for vitamin C serum that is kind of formulated with antioxidants or do I need to have a separate vitamin C serum to get the benefits. I'm currently using the dermatica compounding pharmacy for my rosacea which consists of 15% azelic acid, metronidazole and ivermectin. I have broken capillaries - so I am not sure why brimodine was not included ? Watching your rosacea videos have helped me tremendously. I developed rosacea about 6 months ago after having multiple heart attacks. Preciously other than some fine lines and wrinkles that come in the late 30s my skin was flawless, so I spend so so much money trying to treat it on my own. This probably goes with one of your other videos but I really like the peach slices form of azelic acid 10%, i use that every other day with the dermatica 20% azelic acid in the AM because it was irritating my skin barrier and I had some significant purging. I really love Procure Rosacare moisturizer for the mornings it has licorice root and niacinamide in it and a green tint and so affordable, it really calms my skin. This vitamin c journey is just extra tricky because I've not tolerated any vitamin c in the past, that's why I thought sandwhiching it into an antioxidant Serum would provide protection- but will it provide benefits of vitamin c ?
Thank-you Dr.Liu😊😊! And now I'm sorry that I bought the La Roche Posay vitamin C10 serum close to like 50 dollars at Target! Had it for a few weeks & it's already oxidizing. I am going to go & buy the Vanicream vitamin C serum today. Am 65 & am concerned to reduce my wrinkles... I also have 2 Juice Beauty moisturizers - the anti age stem cellular one & the green apple one & I don't feel these moisturizers are enough to minimize my wrinkles! Am getting the Vanicream
Thank you for this particular video. I’m looking at and trying some vitamin C serums to try to find one that will work well with my skin, not be sticky or irritate my skin, and be affordable as well as having good active ingredients. I haven’t tried either of these yet, although the Cerave product was going to be my next purchase. Now I have two products to try. 😊😊
Not pore clogging. If anything it opens them up 😅. I like it well enough but after consistently using 3 months I don’t see much of a difference. After I use it up I might try Azelaic acid. I have no complaints on the Vanicream. I first tried an unknown brand and it was very sticky. I use that on my arms and legs now. The vanicream is allowed to dry and then I use sunscreen, typically ultra light by Cerave.
I really question wether Cerave is effective, would be nice to see independant clinical trials and stability data. In my experience it's one the least stable ascorbic acid products I've seen, it turns brown extremely quickly... and there's nothing in the formula that gives it that yellow color other than the ascorbic acid degrading.. l-ascorbic acid does not have a yellow color naturally...
CeraVe is owned by L’Oréal the same family as LRP and skinceuticals so I trust they have effective vit c. And yes LAA has a natural yellow hue. Even with SkinC the best studied vit C serum in the market it comes with a yellow tint
@@dr.jennyliu LAA does not have yellow hue, just mix LAA in water and you will see it is completely clear. Larger companies indeed often have the budget and facilities to do the right testing and research, and for unstable ingredients like retinol or ascorbic acid I would also tend to advice to go for larger companies. But it's not a guantee for a stable formula. LRP C10 is maybe even the most unstable vitamin C Ive seen. Btw that patent that L'Oreal now owns says that the formula should be clear just after formulating and only after the stability test it was pale yellow, skinceuticals is often already yellow to beige when you get it and it simply turns brown quicker than some competitors. And no ascorbic acid itself does not have a natural yellow color... Tocopherol could give it a slight yellow color perhaps. It does have some clinical trials indeed, which is nice, but how fresh were those formulas compared to what we as consumers get, and more importantly how does it compare to more affordable products. Something like 160 dollars imo is just insane. A patent is also not a proof or guarantee that that is the only, or best way to formulate vitamin C. These days there are much better techniques to stabilize ascorbic acid. At least products like Timeless and Geek&gorgeous remain clear much longer, made fresh, and you don't go broke to buy a new bottle every one or two months. But I'm quite skeptical of any ascorbic acid product on the market, would be nice to see more clinical trials and stability data..
@@peterkloostermann I have found that keeping the Cerave in the fridge keeps it from oxidizing. My first tube started to turn yellow after 3 weeks and I popped it in the fridge and that stopped. Now on my 3rd one and it stays in the fridge and it stays nice and white!
@@hrhsophiathefirst4060 Thanks, that is definitely a good idea for ascorbic acid formulas. I also do like the packaging of Cerave, it does reduce air in the formula.
I want to try the CeraVe vitamin c but the denat alcohol scares me in general and it is high on the ingredient lists. Is this something to worry about?
No its actually a good thing. It helps to dissolve other substances, stabilize the components, neutralize oil, and deliver active ingredients to the skin..
Hello Dr. When I applied this serum to my face, it did not irritate my skin, but it badly stung my eyes. I washed my eyes over and over again, but the pain still persists. What should I do? Thank you doctor.
THAN YOU, I'M GOING TO TRY EACH OF THESE. !! I have older sensitive skin and the Roc Multi Correction Vit C irritated me so bad, it hurt. Question, do people use these daily or a couple of times a week?
I just discovered you and I am really enjoying your content. I did have a question. Can you use the Vanicream vitamin c with Rosehip oil? If you can, does the order matter? Any advice would be much appreciated. Thank you!
I would like to know your thoughts on CoQ10 for the face. Is it worth using? I bought the Timeless CoQ10 serum and like it, but not sure if I need it or if it’s doing anything.
Thank you for sharing! Did you ever tried Institut Esthederm Intensive vitamine C2? 10 % ascórbic acid+ 2% pro vitamine C. I like the glossy skin effect . Thank you
Hello Dr Liu can u please do a video on peel / exfoliating pads and also drugstore acme pads like stridex and others plus I would love a video on dry acne prone skin
You talked about all the unimportant things, these two products are SO different, the cerave has pure vitamin c in high concentration and the vitamin C in vanicream has a vitamin c derivative and it’s in very small percentage 5%.
Percentages of L-AA and derivatives are NOT equal, meaning you do not need the 10%-20% of a derivative that you need for studied L-AA. 5% is definitely in the range of efficacy as studied for THD ascorbate.
Hi! I’ve been following you for a long while. I think it’s my first time commenting. I’m 60 (female) I’ve been on tretnoin and vitamin c routine for several years. I’ve seen good results. My question is if you’ve ever heard and tried the ZO self activated vitamin c? I’ve bought it twice from my dermatologist. It’s pricy and I’d like to try the cerave one to compare.

What do you think about Advanced Clinicals Vitamin c - is that REAL vitamin c? I'm using it and seems effective - but don't know if it's the HA or the ferulic acid that's doing the job?

Almost finished with my first tube of the cerave. I’m tolerating it very well, no irritation. Planning to repurchase 👍🏻
Vanicream is cruelty-free which is a criteria for me. I use several Vanicream products, including their vitamin C, and I am glad discovered this reliable brand.
Sadly they just hire out their animal testing to a third party so they can claim cruelty free. I wish more creators would emphasize cruelty free.
I just with CereVe would put theirs in a pump bottle like their retinol serums. Seems like a no-brainer.
Love the CeraVe vit c to start!!
I wish I had her skin she is literally glowing!!
Thank you for doing a video for sensitive skin ❤
Thank you, I'm in Australia and can't easily get Vanicream. So I will def be trying Cerave.
That Cerave is oxidized. The serum is not that yellow in a new tube.
That’s exactly what I thought!!
Cerave has specifically addressed that apparently by stating on the product details the following:
“Color might change to amber overtime; this does not effect product quality of efficacy”

Well she said it was an expired one
Thanks for a great video. I am going to go for the Vanicream. Can’t wait to try it.
The Vanicream is amazing! Wears great under makeup as well.
I like the Vanicream vitamin C because it doesn’t irritate my skin since I’m using retinol. Other vitamin c’s have too many other ingredients like acids for exfoliation.
Do you still like it?
Love the Cerave, I keep it in the fridge and no issues with oxidation. I tried the L'Oreal 10% Vitamin C and did not like the consistency at all.
