Waiting for international shipping to open so I can buy everything she sells me! Seriously. I’m blown away by how informative she is in all her videos.

[@user-df9bd3be1d]

me too

[@TheMothernerd]

I used to buy the super expensive l-ascorbic acid serums until I found the CeraVe one. It's amazing and doesn't degrade because the packaging is airtight. I LOVE it!

[@andreamrelitz]

God I love this woman. Not only have you made the absolute best product (including the container!) but it's also no where near as expensive as other brands. I'm so grateful and hope you are so so blessed Dr Shereene! 🥰

[@jgthao]

Can you review Image skin care power C serum?

[@Sadrose21]

What is the name of her product? I didn't catch that.

[@andreamrelitz]

@@Sadrose21 her Vitamin C moisturizer is called Active Seal from her skincare line "Major Fade"

[@Sadrose21]

@@andreamrelitz Thank you!

[@WooWooGirl]

Are we looking at the same product? I replayed it twice and thought Dr. Idriss said the Vit C cost 15.00 which did seem unusually inexpensive for a Dermatologist brand. I think I totally misunderstood though...because on her site it sells for 58.00 per 1.7 oz Jar. A little steep for my wallet. It is comparable in price to some of the others she put forward. I am sure it is awesome though. I truly do enjoy watching Dr. Shereene's videos. She is full of helpful advice. If I lived in NY...I'd probably see her for a procedure of some sort...in the future.

[@marcelachiran1599]

It would be very helpful to have some tips from you for the women who are going in menopause because skin is one of the first thing which will be affected, please do a video about it!! Thank you 🥰🙏😊

[@Lighttriumphs]

Agree

[@fruitsaladgirl]

Literally obsessed with every damn word that comes out of her mouth, my gal, my guru and the actually “bomb” of skincare! Listen up bitches, she’s the one!! 🙌🏽

[@bxi1547]

You need to get a life.

[@almaalma3871]

Dr. I love all your helpful videos. I lives in Miami Fl as you know the sun can b brutal here, and sometimes is hard to find Doctors that are motivated to give good advice and recommendations. You have no idea how much you have helped me all those years ( I discovered your Chanel during Covid) and learned so much ever since. 🙏🥰

[@judyxie]

I love these types of videos from you. It’s soo helpful! Thank you!

[@ashleykasim6873]

Super informative as usual. Keep up the amazing work!!

[@Isabellawrob]

I am very bad at focusing on videos but I was completely committed to everything you were saying and I’m definitely a new subscriber. I love that you keep it real and educate everyone at the same time in your videos. Thank you!!

[@Sentient_Goose]

I love THDA! Been using the hermetically sealed vanicream version. I have sensitive skin and it's the only C I can handle. The packaging is also so well thought out. It's been about 2 months and I'm noticing that the darkness under my eyes is starting to even out!

[@dianegreiner4054]

I absolutely loved this video! Would enjoy seeing more of these specific topic videos. It helps so much!!! Greetings from Michigan! 😊

[@cheerios4canaries]

Stay blessed, love your informative videos that cut straight to the point.

[@sleepykirsty]

This was EXTREMELY helpful! Thank you so much!!❤

[@neilajoseph223]

Such a timely video! Thank you so much for this breakfown

[@michellemiller7818]

I got your moisturizer and I’m obsessed ❤ great price, great PLAY TIME (use all over my chest) leaves me silky smooth and I can see a difference. Please don’t ever stop making this!!!

[@adua78]

Man, Skinceuticals is taking part in the “inflation” free for all I see. It was $166 just last year, now $182? Nope. Drawing the line. Timeless, here I come.

[@dopestchannelever]

Yes!! I was literally shocked when I went to buy it last time. Watch next year it’s gonna be $200

[@dorismoran9641]

Sad. Just bought it and thought the price had increased. (Don't think I was charged quite as much as $182 though). My last bottle lasted almost a full 5 months. I love this product.

[@anitawallace2166]

That’s insane. For that price it needs to give me a full face lift, liposuction and clean my house.

[@dianaf6333]

I love Timeless 😊

[@Anilat1029]

What is going on!? with these prices! I just went to get my favorite moisturizer. Lancôme went from $50, to 80 now is 135! 😑 and the night cream is now 160 🤪 No way! gotta find another brand now 🤦🏻‍♀️

[@gabriellasetti657]

Hi Dr. Idriss! Can you please do a video on propolis, its purpose, and its pros/cons? I like it because I do feel like it boosts radiance, but it sometimes irritates my sensitive/reactive skin. I’d love to learn more about the ingredient and how/if I should incorporate it into my routine. Thank you!😊

[@lcr5910]

Dr. Shereene I absolutely love your pillow talk derm line! I’ve been using it since January and It has definitely already made a difference in my skin. It’s very hydrating and I have sensitive skin and it doesn’t irritate it at all ☺️ I will continue to repurchase it! I can’t wait to see what else you may come up with down the road!

[@peterhallett2256]

Thank-you Dr. Idriss. You have done your research to break it all down. Extremely helpful.

[@cindypalumbo7503]

I loved the updated vitamin C video!!

[@akirebara]

Was wondering what she thought about Maelove. I’ve been using it for 6 months now. I really can see the brightness of my skin!

[@orozcoaj69]

I was also hoping she would talk about it

[@amandaspring5094]

I love and use that one as well 🥰

[@b99lz]

i’ve used the maelove vitamin c for over a year now!! it’s my absolute go-to. it’s affordable and makes my skin literally glow - especially with consistency!

[@Shaaunii]

Love your videos! Would love to know more about growth factors (what they do, effects of longterm use and recommendations)!

[@loutol2952]

Your passion for your chosen topics is infectious….. bang on the table and let’s go! Great to see.

[@clarissatoplar8071]

Such an informative video! I had no idea! Thank you so so much that's so helpful!

[@dzuel09]

I finished my first bottle of the Skin Ceuticals a few weeks back and saw all the comments praising Timeless. I ordered the 20% (I tolerate L-Ascorbic well) and so far it’s too soon to tell how I feel but I love the pump. I can’t wait to try yours, when I get through all my current moisturizers. Thanks for this deep dive. I love me some vitamin C

[@christyinman7568]

Magnificent breakdown, this is exactly what I've been looking for as I search for a new vitamin c serum. Thank you so much!

[@threepoundcottagethedartmo1313]

Looking forward to your products being available in the UK - love your videos!

[@evarkf5303]

Awesome video. Very informative. Thanks doctor!

[@romamohammed1148]

I have been watching your videos for a long time.. you have guided me in my skin journey..!!! Always helpful !!! Lots of love to you ❤️

[@cherylb348]

As a science geek I adore your videos and that you talk about the science & facts

[@saydaalongi659]

Dr. Sherreene, where have you been all my life?! You are amazing.

[@blacktiger2154]

I would love a video on which other active ingredients you can combine or use in the same days as each different form of vitamin c!

[@theadventuresofkingyandoll6249]

Thank you again for this informative topic. I have used most of these products you have discussed and have found a winning combination that works for me! ❤

[@sewsed]

Please share!!

[@louiseclarahess7491]

Tysm for this video - very clear anf helpful. I have a few vitamin c serums standing in my cabinet and this helped me find out which one contains what and which one to use atm where my skin is more on the sensitive side - especially when you take the time to share products linked to the Ingredients it’s very helpful! love your channel and learn from you ☺️🙏🏼👌🏼

[@lexioatley4853]

Singularly the best round up of the Vit C subject matter. Thank you for sharing your wealth of knowledge in such a comprehensive yet understandable way.

[@lt9922]

Oh man this was so good! Super helpful as I’m currently on the search for a new vitamin C product. Thank you so much for all your research and explanations, very much appreciated!!

[@lerekomolefe4323]

Looks really good, I love that it does not look too sporty so it goes well with your outfits as well❤❤❤❤

[@jennandcherries]

As a lover of science and knowing how things work, I love your detailed explanation of how ingredients and cells work ❤

[@AmandaLeins]

This was really helpful, thanks! I'd love to know more about growth factor and what it's supposed to do.

[@ivanaknezevic1708]

I feel like nobody is talking about rosacea and combination skin, also Erythematotelangiectatic rosacea - what are the best treatments, care? if you don’t have dry skin and red swollen bumps… - I guess never mind about other types of rosacea…if possible it would be really nice to get some advice for us with milder types ❤

[@aaronpina6466]

Love your videos as always! Also love the setup! ☕️🧡

[@yiotamintzas801]

Wow , that’s amazing and so much more to all, theses products thank you so much 😊 for sharing your knowledge with us all.

[@mlcs179]

Thankyou for providing scientific information, in an easy to understand way. Showing us products that are varying prices and the difference between them, you are a gem. Love your channel.

[@neresq]

My hubby and I use - and LOVE - the Maelove GlowMaker, which seems to be a dupe of Skinceuticals, but for only $30.

[@lina478]

Thank you Doc for detailed information. You are amazing

[@longevityexercises]

This is the best video I have ever watched on health and beauty! I have learned so much on VC that I immediately understand why I needed VC in my fight against wrinkles and dark spots!! Thank you so much - by the way your talk is also very fun to watch!!

[@jilliandonaldson9868]

The timing of this is perfect! I bought the l'oreal vit c serum just before xmas bc it was on special offer in Boots. I never loved it bc the salicylic acid is too drying for my skin anyway, but the dropper style bottle that you're always complaining about proved its inefficacy recently as it's totally oxidised now and I don't want to finish it. I'm afraid it will do more harm than good. I was literally thinking this morning, I wonder what vit c I should go for now instead. So thank you for reading my mind! :)

[@leanne0145]

If anyone is looking for a less expensive THD serum, Vanicream has one for sensitive skin for about $20. I just bought it, so I don't know about the results. But, it has a 5% concentration of THD ascorbate and ceramides, and it comes in an opaque tube with a pump. It's definitely missing the bells and whistles that the pillow talk one has, but I'm still excited to try it.

[@ratiannemh283]

Hii is it good?

[@vr4288]

Shereen this hair colour looks really good with your skin tone!

[@maryktime]

I cannot wait to purchase your products. I definitely will be finding a way to do so if I end up traveling this year to the states.

[@67laurac]

What great information! You are a gem Dr. Shereene! Would really love to hear more about growth factors and copper peptides...should they be used in the am or pm and what products can they be used with?

[@effusivevehicles1458]

your videos are my med school study break; LOVE YOU SO MUCH 🤩🤩🤩

[@bearemysmom]

One of my faves for THD is the Good Molecules discoloration serum. It comes in a dropper, it smells nice and it’s budget friendly

[@emmAGlad2CU]

Love pillow talk derm active seal! Also tried Sunday Riley based on the recommendation. I think they have changed the formula texture, because mine is white and not a liquidy as in this video. Actually prefer the newer texture. Thank you! Love all your videos!

[@marypana2380]

I have only used Paulas Choice Vitamin C , my skin loves it !!

[@beks4002]

Hi Dr. Idriss! Love your channel!! I would love a video about coenzyme Q10! ❤️❤️

[@NooSut]

Greeting from Thailand! I just recently found your channel and have already been through most of your videos. Thank you so much for sharing so many good things that can truly save our bucks and faces :)

[@riser7509]

I feel like I became a dermatologist. Very interesting and informative video. Thank you for your help.❤❤❤

[@umatilla1253]

After watching one of your early videos, I have now been using the summer fridays serum for >6 months and really love it. I use it every morning with zero irritation or redness. The max I could use L-ascorbic acid was 2-3x/week. With that came redness, irritation and the inability to use tretinoin more than 2x/wk. Now I use tretinoin nightly, again with zero irritation. GAME CHANGER!! My cosmetic derm was even a bit surprised at the change because she didn’t originally approve of abandoning Skinceuticals. I am just finishing a bottle of summer fridays and going to try the pillowtalk derm when it’s back in stock.

[@ssoboh22]

Loved this video! I have your whole product line, all I add to it is my Tretinoin and eye cream and I’m done. I’d like to see a video regarding laser/micro needling therapies for keeping skin vibrant and decreasing lines, aging gracefully…comparing fraxel, clear & brilliant, Morpheus8, other micro needling etc. which devices are best for what and how often to do them. Thanks!

[@dionnelatham4401]

I’m excited to try your major fade product. I’m getting another round of the Enlighten peel in a few weeks and I plan on adding your product into my routine for some post peel maintenance.

[@stephanieoyebamiji4854]

Wow, this is a VERY informative and educational video. I thought I knew all there is about Vitamin C, but I learned so much from this video. Thank you so much Dr Idris .

[@vinasays9448]

Can you pls talk about the differences between and pros and cons of microdermabrasion, micro needling, chemical peels, and laser treatments? And also how to combine these with actives in our routine? Hugs from CO ❤😊

[@esthertheuri7847]

I second this. Also cons on skin of color

[@CaliberDawn]

Yes, PLEASE! Esp the difference in what it’s treating e.g. scarring and if it can be used on thin areas. I have an appointment for micro needling on the outer parts of my eyelids due bad scarring from surgery but I’m apprehensive since the skin is so thin there. (I got it done once n I was too scared to go back because it was so painful since the needle was pretty much going against orbital bone). They’re also recommending microdermabrasion to help smooth surface of scar but I’m also unsure since the skin is already so thin. 😢

[@starryeyed2511]

Yessss. ESP when on tretinoin, I’ve no idea what kind of treatments I can do. I’m told to layoff treat 2 weeks before and after a laser facial but that is just not possible and I do not want to stop the retinization process every month. 😢

[@kathrynfeczko9167]

Agreed! And can you discuss the Lyma Laser? So few unbiased, medical minds reviewing. Thanks!

[@donnapalmer2099]

Is Collagen needling a good idea? I'm getting it done in a series of treatments and it looks promising. What's your thoughts?

[@sballantine8127]

I cannot tell you how much I appreciate the timestamps, thank you so much.

[@gemmaelizabeth4608]

I love your content!!!

[@juliep9156]

Good Morning, Dr. Idriss!! I look forward to Saturdays (not to walk my dogs) but to watch your videos! The new rave is BeautyStat Vit C but it's $85 or $88 a bottle, but it is a pump. It does burn a bit but I also use tretinoin on my skin so it's always turning over. I have severe melasma and am always putting things on my face during the winter months gearing up for the summer (which is a losing battle). I am most certainly going to pruchase your Major Fade when this runs out!

[@quelbelle6148]

My virtual skincare bestie. So solid, so genuine…why am I just now finding you? I needlessly tortured myself through all the other popular channels and still left confused by their content and annoyed by their personalities. Oh well, that’s done. Many effusive thanks!

[@slhilliard]

Copper peptides next please. Thank you!

[@bluberrilovr]

Thank you so much for laying this out! I had tried the yellow Timeless and Neutrogena capsules in the past, and both dried the hell out of my skin. I had given up on vitamin c. I didn't realize there were different kinds. I'm going to be trying your Active Seal!! Very excited. I LOVE the concept of your packaging---being able to get every last ounce by opening it up in the end! ❤

[@rowan3946]

Great video Dr Idriss. Your skin is exquisite. I’ve been using Skinceuticals CE Ferulic for two years now. I have sensitive skin so I peeled a bit at first, but hyperpigmentation is significantly reduced. Thanks for the tip about the pump bottles😉

[@susanb3989]

Loreal revitalift is a drugstore brand, containing the shelf stable Tetradexyl vit c, and I’ve been using it for years. Only 10% which is great for my sensitive skin.

[@adrianamiranda2304]

Thank you so much for the great class you gave us on Vitamin C. It would be a great topic to talk about scalp products and how do they work. Thank you again

I love the Allies of Skin 35% vit C. 25% Ethylated L-Ascorbic Acid and 10% Tetrahexyldecyl Ascorbate. And also love Major Fade Active Seal! 💜

[@ceen5496]

Do you feel it's as effective as 15% l-ascorbic acid

[@maggie_n_ms]

I love the Geek and Gorgeous C-Glow. It is 15% l-ascorbic acid. I do have to order it and I get two bottles at a time. I follow their directions and keep it in the fridge and decant into a smaller bottle for use. I have never had any go bad doing it this way. I also use the G&G A-Game 10 retinal so I usually have enough in the order for free shipping.

[@angelinebiswas7611]

I love it too! Can only use in the summer for some reason less irritation then

[@Snowfox23]

Not effective to my own experience. I’m switching to Paula’s choice

[@masterculturedunkerque7918]

Trying it right now and very great so far !

[@heidikamrath1951]

Ships from England, right? Free shipping to US with minimum purchase?

[@momdocindc]

If ordering from the US, it ships from Hungary. Free shipping if order is 60 euros. I use a few of their products so it is easy to get to 60 euros. I order 2-3 C glows at a time and keep it in the fridge.

[@arib.6393]

Dr. Idriss, your products are wonderful! Can't wait to try them. Please, start shipping to Europe asap! 💕

I’m scared it will grow and make my eyesight worse 😅

[@lifeatthefino2793]

Dr Idriss, I have been using for several years Isdin Vitamin C Ampoules and love them. I also LOVE the packaging, it's in a glass ampoule, You use it up in 3-4 days. I would love for you to review this product. For clients that can not afford Isdin I sometimes recommend Vichy Vitamin C Ampoules, they don't have the added moisture to them like Isdin but also I would like for you to review. Thanks.

Incredibly well made video. Subscribing forever. ❤

[@AM011]

Dr Shereene pls do a video on nasolabial fold. As this is due to sagging, volume loss and there’s also line, what treatment(s) can solve these 3 problems? Pls do a deep dive on this 🙏🏻

[@Mini_Min_]

I have oily, super sensitive skin and I love Vitamin C! The first one I tried was 10% and I had to mix it with another product because it was causing stinging and redness on its own. It takes gradual geting used to. Now I use a 5% serum from Purito and I find it mild enough to apply every other day.

[@kiwifrenchie6036]

Never tried vitamin c Should I just try this or timeless

[@GlaTre]

Love your videos! Could you talk more about Korean skincare, sunscreens, good brands for each concern, ingredients, etc.

[@fahomedchowdhury5738]

Yah! I was thinking about it too! Have you tried any Korean brand?

[@GlaTre]

@@fahomedchowdhury5738 Like better Korean skincare than any other. Have tried a lot of moisture products from Cerave, La Roche Posay, Eucerin, etc, while using tretinoin due to damaged skin barrier. The only ones that repairs and now are my holy gail’s are Korean: Pyunkang Yul essence toner, Pyunkang Yul Ato cream blue label, Illiyoon Ceramide ato concentrate cream, Cosrx advanced snail 92 and Etude Soon Jung 2x barrier intensive cream.

[@jatindhir2681]

Great video with soo much information. Please share your thoughts on below mentioned forms too:- 1. Ascorbyl Tetraisopalmitate aka VCIP 2. Ascorbyl Methylsilanol Pectinate aka ASCORBOSILANE

[@GenXIcon]

This is one of the most useful vitamin c videos I've ever seen. I've been using Andalou Naturals night creams, moisturizer, sunblock and cleansers in a variety of ways for a few years because they feel good on my skin and my skin is very sensitive. But I could never figure out if any dermatologists actually supported the brand. At least with this video I was able to see that my vitamin c day cream has MAP, Dr. Idris' least favorite and useful! It's good to know. I use a lot of their products that aren't vitamin c and have hyaluronic acid instead but still good to know.

[@vjwlove]

I was a bit surprised you didn't mention the Allies of Skin Vitamin C. It is the best one I have used thus far. I use it once a day and it lasts for 3 to 4 months. It also comes in a pump.
