"my pronunciation is shit, but that doesn't mean I don't know what I'm talking about..." I need that on a shirt. Literally my mood in every academic situation.

She has to be the most entertaining yet informative derms I've ever come across and she's so pretty omg

"My pronounciation is sh*t but it doesn't mean that I don't know what I'm talking about." - I felt that on another level :')

I FINALLY found someone informative who talks science and analyzes ingredients, I was a chemistry student and can’t buy a product without analyzing it’s label, you’re my HOLY GRAIL KZfaqr! Thanks Dr Idriss 💕

I live with a smoker (hubby) and we dont get enough ventilation. If we get a divorce, I will cite as cause: "Irreconciliable Oxidative Stress"

It would be interesting to know more about integrating Vitamin C , Retinol and exfoliants in the same routine! (Edit: I didn't necessarily mean using all 3 actives at the same time, rather for the day/night and week routines)

The vanicream vitamin c has the tetrahex one you like, plus it's $18. It only has 5% in it, but my super sensitive post menopausal skin loves the 5%. Vanicream is the only vitamin c I've found that I can tolerate daily. I've tried 10%, and my skin was red, dry, and irritated after using it several days.

For those who are interested in seeing the study of the vitamin C derivative Sodium Ascorbyl Phosphate (SAP) being a good choice for acne prone skin, the title is "Sodium ascorbyl phosphate shows in vitro and in vivo efficacy in the prevention and treatment of acne vulgaris", it's a very nice read: they mentioned how it initially had no activity against p. acnes bacteria at the concentration of 0.5%, but when they increased it to 1%, within 4 hours it had a very effective reduction in the p. acnes bacteria, and they even showed a before and after picture of one of their representative subjects who took part in the treatment process. Thank you Dr. Shereene for making these Let's Get Intimate playlists, it helps me research even further about skincare ingredients as I initially wasn't sure where to start in terms of researching. Your videos give me a foundation of understanding and allows me to explore even further to research regarding the ingredients. I appreciate your help a lot.

Being a med student I would be grateful if I had a study buddy like you like it's so interesting to listen to you!

Currently in my first year of medical school studying immunology rn and your videos are so motivating for me (perfect study break) so thank you Dr. Idriss!!

Shereene I’m a dude and half the reason I watch your postings are because you’re funny as hell. Your my go to on skin care. Do what you do! You’ve been a big help.

I love HER energy! Doc you're a whole vibe! Much love 💕

I feel like I just found my new favorite youtuber. She is so informational but finds a great way of delivering this to make it memorable and entertaining.

Why do I love her? She is like my hype sister. I love how much she gets into her education. As health care providers, it is our JOB to education. Thank you so much!

I love the way you always give a wide $ range of products. You show that just because a person doesn't have a lot of $$ in the bank doesn't mean that they can't have the benefits of products and have great skin. Thank you so so much!

I’ve watched so many vitamin c videos and this is hands down the easiest to understand and most straight forward. Thank you!! Subscribed!!

I love your personality so much lol you’re a whole vibe. But also as a PSA to everyone: dermatologists were often times the top of their class in medical school and/or had top board exam scores because dermatology is one of the most competitive residences to get into. So that just makes me appreciate her personality so much more. Brilliant with people skills and a sense of humor is hard to come by.

Shereen you are my absolute favourite skin care expert on KZfaq (and I seriously think I've seen most of them!) , THANK YOU for all you do!!! 💜💜💜

I’m binge watching your videos! I have so much respect for you and your words are close enough to holy and I pay close attention. Thanks a ton! 🙏🏽

I never comment on videos. Ever….. but I just want to tell you how much I APPRECIATE YOUR VIDEOS!!!! You are so thorough and make it enjoyable!!! Lol!! So many of the other dermatologists on YT are DRYYYYYYYYY and down right miserable to be watch… one of them I have to listen to with headphones because my husband can’t stand her voice, lol…. 😬😬😬 Not to talk bad about others, there is something for everyone, right? And you are FOR ME!!! Lol. Thank you for the time you take to make these, they help!!!

You and Dermangelo are the only ones whose skin advice I listen to. So knowledgeable and straightforward but so fun. Thanks for another great video!

Not only are you educating and very informative, you are funny. Love your delivery!

You are so educated. I love your delivery and your interest and how it comes through. So many Derms and Aestheticians as well; don’t consider oxidation, packaging, heat and light.

You are a blessing on earth, cherry on top with humor. I LOVE YOU. Also the only motivation left for Derm school.

Finally there's someone talking about the different derivates in detail! I'm so glad you started your KZfaq channel dr. Idriss. By the way, Facetheory uses sodium ascorbyl phosphate, I love their products!

I was scrolling through my recommended and was like, "Another skincare video. I've binge watched more than enough of these." And was about to go right pass this video until I saw how glowy her skin is.

Thanks for mentioning vitamin C on sensitive skin since I’ve been using it every morning and once in a while I’ll use it twice a day, and I just found out the Timeless 20% vitamin C E ferulic serum is actually too high strength for me. I watched another video where vitamin C around 20% and 25% isn’t well-tolerated so vitamin C at 15% tends to be the best (providing best antioxidant properties while having lowest sensitivity/inflammation so highest tolerance for all skin types). So if anyone is experiencing redness/inflammation/irritation/flaky skin from vitamin C, definitely try to get 15% vitamin C. The super pricey Skinceuticals vitamin CE ferulic serum is formulated with 15% vitamin C. Edit: Please talk about vitamin E/tocopherol and vitamin B5/pantothenic acid! I love the La Roche Posay cicaplast baume b5 and would love to know the science behind B5 products.

YOU HAVE THE (second) MOST BEAUTIFUL SKIN THAT I’VE EVER SEEN ! Please, I need a full morning and night routine Dr.

Amazing vid! I love how you are able to summarize so much information in such a short time and in a very simple way for everybody to understand!

Dr. Idriss is the most beautiful dermatologist. Your skin is amazing without a full face of makeup.

Your videos are so informative, clear, and straight to the point. Thank you!

I am trying to take better care of my skin and your content has been very informative. The cherry on top is your energy, I just love it!!! so refreshing :)

I just feel like I’m slowing down my wrinkle production one dr idriss video at a time...like this whole channel is anti-aging ykyk

You’re the one that made me start wearing vitamin c and sunscreen, i truly thank you for that❤️

Just discovered you and I love you already. I’m so grateful for the dermatologists on youtube, thank you for taking the time to educate us

I keep finding articles about the benefits of vitamin C. SO glad I saw this before I went shopping! Thanks, doctor!!

Your channel inspired me to finally make a skincare document with my night & morning routines, notable ingredients, favorite products, layering... etc. I guess I'm officially a skincare nerd now. Thank you so much for the amazing information

i'm hoping to get a diploma on skincare at the end of this pandemic :)

Thanks for sharing a real talk regarding skincare Doc. I learned a lot from you. I am on my early 40s and started trying products mid 30s. I know its not too late yet to take care of aging skin. Getting hook up to your skin care informational vlogs.

I literally watch your channel for the laughs! I love brilliant women who can laugh at themselves! Thanks for your videos!!!

The most detailed series of vitamin c on youtube ,ty doctor beauty ❤️,much love from india

I just love you Dr. You're my bias with all these wannabe skincare gurus! Keep blooming with grace.. Please don't stop enlightening us. Cheeers 😊😘🥂🥂

i always write down so many notes every video u make. love your efforts and knowledge being shared to us

Dr I - you are the best! Great info and presented with your natural charm. So helpful. I just bought a sample size of the Skinceuticals - I couldn't possibly afford to buy the full size and actually thought to myself it is better to buy the tiny size so I can try the product and not worry about oxidisation. When you covered it here it was very validating form me as a novice. Thanks so much 😊

I love that she is addresses the shelf life of vit c. So important to know!

The production quality on this is outstanding, title too 😂

I watched this video whilst doing my hair for the night and completed it all together. I absolutely loved every part of it, thank you fo sharing on the the different types of Vitamin C and their benefits as well as how they work. You are officially my favourite KZfaqr and Doctor (after my GP of course) Also can't get over how beautiful and funny you are

I loooooove your content. It's everything I was expecting to learn from a trustful dermatologist♡ thank you so much!

I just bought a vitamin C serum yesterday, but was hesitant about it. Just in time! 💜

Your personality makes me feel like im listening to my big sis giving me a mini ted talk. Love you 💛🧡❤

After using the addition of vit C and retinol in my skincare routine for 2 weeks. I can see a big change on my skin: Skintone more even and i can feel the skin more pump. Love all of your videos. Thanks for that 🥰🥰🥰

Great video! Helpful, systematized, well explained...just 10/10!

Your videos are always so helpful and so informative! I really love and appreciate your effort to educate. It can be a bit overwhelming for someone new to skin care (🙋‍♀️) I think if you started a series on KZfaq, like skin care for dummies/beginners, it would be great. To have just a guide into how to start and get to where you need to be.

Hi, would you be able to make a video for rosacea? And maybe what products can be used in various stages? Like when you only have milk redness on the cheeks and a few broken vessels. Thank you 🙏

Loved how comprehensive your videos are!

I was aware that vitamin C and copper are inversely proportional to each other. I had copper poisoning from my copper IUD (Paragard) and I was researching natural remedies because I was sick and having trouble finding someone to remove it for me. I started taking a very high dose of vitamin C pills and I did experience some relief from my symptoms. Ladies, I hope this helps even one person. If you have a copper IUD and you're not feeling right, it's not in your head and you're not crazy, even if you've begun to think you are.

this is how I'm pronouncing "Glossier" now. great video Dr. Idriss

If you’re still looking, Biossance has the Vitamin C Rose Oil with Tetrahexyldecyl Ascorbate for $72. It’s formulated with Squalane as the base. Loved the video btw

Your videos are very insightful, but it’s the personality for me ❤️

Thank you dear Shereene. Very thorough and for all budgets/skin types indeed.

I was literally just about to order a vitamin C serum.... im scared😂. Thank you so much for the amazing content ad always

This is my first video and I’m obsessed. When she said if you want to spend money, I’ll give you my Venmo account I knew I was hooked 😂😂

The most informative and useful channel!!!

OMG i just found your channel and I'm OBSESSED BY IT hahah I love your videos and your way of doing content!!

Wonderful, educational video. I love the way you explain it in a way anyone can understand.

You’re literally my favourite person

I have just discovered your channel. I'm in love with your personality and well put together information!

I just found this vid and your account. I love your straight talk style and sense of humor. I subscribed and am looking forward to watching all your videos!

Just for everyone: The Timeless vitamin C serum is also combined with vitamin E and feurulic (sorry for the spelling of that if it's wrong 🤣) I've used one up and will repurchase, it's brilliant

I don’t know what it is about how you explain things. I finally understand vitamin C and which one is best for me. Instantly subscribed!

I am trying to add peptides into my routine and trying to figure out what’s the best vitamin C derivative and your information in this video really help!

Love getting the real science behind skincare and not the marketing BS! I was wondering, what are your thoughts on the supergoop vitamin C + SPF 40? Since SPF is usually the last thing in a morning routine, would the vitamin C even be absorbed?

I love your videos, Dr. Idriss! ❤️They are so informative. Would you mind doing a pregnancy approved skincare video? I'm scared to death of putting the wrong ingredients on my face.

The french accent of glossier? Amen. That gave me life.

Just adore you Dr. Indriss! Love this

I come back to this video multiple times a year when trying to remember the good and bad Vit-C's!! It is my holy grail vitamin C video :)

Found this video really educating, helps to understand the confusing world of skincare ingredients. Thank you! Please may you do a video on redness and capillaries on skin?

I lovee this video, more content like this for different ingredients please 💕 As a cell biologist I would love to see some of the studies too xx

I love the Sunday Riley one. I got it as a sample but I fell in love with it instantly.

I just recently found you and LOVE YOU!!! Just bought Sunday Riley one to give a shot. Thanks doc 💕

I wanna be like you when I grow up....but I’m already 40🤣😂🤣

LMAO she’s hilarious 🤣 not the red solo cups and all the oranges 🤣🤣🤣🤣

Thank you SO, so much for this video! I laughed, i took notes and I didn't feel like I'd met another dead end when exploring skincare

OMG you are a whirlwind! I kept meaning to research what part Vit C plays in collagen production and now I know! Amazing 🤩 Thank you for your wonderful content 🙌🙌

Dr. Idriss, I just was aware of you about a few weeks ago mentioned to me by my sister-in-law. I absolutely LOVE your videos. I've only seen several so far but I love them! You are very educated, knowledgeable and familiar with all of the skin care products! I also Love your personality! You are so beautiful and also down to earth. I love how you spell everything out for us skin nerds and give product recommendations even on things you don't think are that necessary. It must be a lot of editing work to put all the pop ups in your videos but I love them! I'm so very happy for you that you finally get to open up your own practice in September! Do you have a definite date yet? I also loved the video that you shared your story with us and got emotional. It makes me more happy for you that the KZfaq/internet people backed you up. 😉 I don't wear makeup and luckily I just turned 41 and I still have great skin, probably because I'm half Asian (Korean)/half White. I want to start taking care of my skin now while it's still able to slow down the collagen breakdown. I actually learned about collagen from you. I'm glad you also don't think cleansing your face twice a day is that good for you. Before I found you, I was totally lost about which products I need. I'm more on the strict budget side so I have to just wait a little bit before I can get all the skin care products I want. I decided that in the morning I'm going to do a topical vitamin C that I will store in the fridge then use my facial sunscreen. I have sensitive skin as does my mom and sister so I'm using CeraVe for all my products. Do you think that's ok? Plus they're cheaper than brands you mention. I liked that you do your "nighttime" routine when you get home from work so the products have time to work instead of doing it right before bed and the pillow case soaking it all up. So at night, I'm going to use a facial cleanser then moisturize and then do a test patch of retinol. Since I have sensitive skin, I'm going to start with just once a week for 4-5 weeks then twice a week for several weeks then 3 times a week. Do you think I should even go up to 4 times a week? I was going to use vanicream for nighttime moisturizer because of all the benefits of glycol but the CeraVe pm moisturizer says it's ultra lightweight. Is that a good thing? It also says it has Nia***** - I forget what is called and it's non-comedogenic. If it's a bad thing, why? I trust your honest opinion. Which nighttime moisturizer do you think is better, CeraVe pm moisturizer or vanicream? If I use CeraVe and it's ultra lightweight should I put two layers on before applying the retinol or do you think one layer should be fine? This is actually under my significant other's sign in. I'm technology challenged. I know, I need to learn. I know you must be crazy busy since your practice is about to open but if you could email me and answer all my questions I would love you forever!! I think I can check this comment again to see if you replied to it. I just would rather use the app and I can't comment on the app. How dumb is that?!

Omg you have the cutest personality, I love watching your channel . It’s great teaching and entertaining 😂

Where in your skincare routine should you put your vitamin c? Sunscreen, moisturizer, niacin, makeup primer, makeup?? What order do you suggest? Thank you❣️ I'm SOOOOOOO glad I discovered your channel❣️💙😘

One of the most useful videos on Vit C I’ve seen!

PLEASE post an updated sunscreen video with your favorite options! ALSO a step by step morning routine and night routine! the order of all these products is confusing! thank you!!!!

Been using the Sunday Riley CEO Glow and my skin has been LOVING IIIT. So glad to know it’s worth paying for 😅

This is soooo informative. 😘 Thank you so much Doc Shereene! ❤

Thank you for the information and the great delivery!

You are lovely, honest and highly intelligent for a young woman. Refreshing to see a Dr. on KZfaq not pushing products under the guise of informing the public, for a profit. Well done. New subscriber 👏👍☺️

Thank you for the information.. makes me want to study more about skin care. I love how passionate you are . And thank you for being yourself. Can't wait to learn more

Very happy to stumble onto your channel. I hv subscribed and will listen to all the clips here. Your clips are so helpful and informative. Thanks 🙏

This was super helpful! Thanks all the way from Australia! Love your explanation

SO Interesting, thank you! I'd love to hear your take on laser therapy and chemical peels that are professionally administered at beauty salons/dermatologists. It gets quite overwhelming when there are so many options for skin tightening, radiance (brightening) and even tone.

I really loved the in depth vitamin C video! Really good job Shereene 👏🏼 I recently bought the Vichy 10% ampoules , I don’t see any Vichy recommendation on this video, should I take it as a sign?

So happy I found you! Could you please make a video on menopause routine?! So much expensive and useless stuff there for us - who are trying not to get old!))

She is the funniest and cutest doctor on youtube!
