*VIDEO SUMMARY:*
The six holy grail of actives:
1. Vitamin A (retinol, retinoids, etc)
2. Vitamin B3 (Niacinamide)
3. Vitamin C
4. AHAs (Glycolic acid, Lactic acid, Mandelic acid)
5. BHAs (Salicylic acid)
6. Benzoyl peroxide
*_Beware of combining:_*
• Vitamin A with benzoyl peroxide. Because benzoyl peroxide is an oxidizing agent, and a retinol is technically an antioxidant. So together they can cancel each other out and be futile, and be very irritating.
- _How to combine?_
Spread them out. Use the retinol in one night and the benzoyl in other nights.
• Vitamin C with vitamin A. It depends really, I don't know how to write this part so just re-watch the video. (9:49)
• Vitamin A with AHAs. Only if you're a veteran and if you have tolerated the retinol, and retinol with AHAs together. Same is true for vitamin A with BHAs (salicylic acid), just be careful and get acclimated with the retinol first or your face will explode (not literally but you get it).
*_Best combo:_*
• Vitamin C with ferulic acid and vitamin E. It's just good.
• Vitamin C and Niacinamide. It might be very confusing because something... something... (11:58) but studies have shown they boost each other's effects. Combine them all you want.
• Vitamin C and spf. No brainer, they're good together, they were meant for each other.
• Vitamin B3 (Niacinamide). They can be paired with everything, the only thing to keep in mind is to keep the percentage of Niacinamide to 2-5%, no need for higher.
• AHAs with vitamin C. Both are formulated in acidic ph, so they tend to amp each other up. Be aware of this combo if you have sensitive skin.
• AHAs with BHAs. They're both acids but they work differently, so they don't clash. Just be aware that you don't need a crazy high percentage when combining.
Moral of the story:
1. Have a basic skincare routine down.
2. Don't blow your face out with high percentage concentration
3. When in doubt, patch test it. If you have sensitive skin, always patch test your product combo. Otherwise, go to town and make a skin routine smoothie.
Edit: I'm so glad I could help some people out with this comment. We are all in this together to figure out the puzzle that is skincare.
thanks a lot
Thank you
Wow thank you! Seeing it in writing helped me to understand it better! Thanks so much ❤

Thank you
Timestamp 'niacinamide + vitamin B3' is not correct. Because niacinamide = vitamin B3.
Niacinamide can me combined with everything, just be aware that the concentration is not higher than 5%.
Thanks for the timestamps @boonavite3200 !
Thanks! Will edit
I'm so glad you have a channel, Dr. Idriss. I have stopped watching other skincare channels because i want my information to come from someone who is knowledgeable..... like a dermatologist!! My skin has suffered from the misinformation that I've received from some of these channels. Not anymore!!!!
Knowledgeable and trustworthy!! Thank you Dr Shereene
Couldn't agree more!! Her and DrDray are my go to on here I learn so much from those 2 awesome dermatologists thank u Jesus!
Her and dr dray are my go to
@@m.7340 SAME! Tho i also like Dr Dray, Dr David Lim, Dr Alexis Stephens, Doctorly and the Budget Dermatologist 😅🥰💕 they’re allllll so amazing!
Yep, also Michelle Wong from Lab Muffin, a cosmetic chemist, has been dispelling so many beauty myths (especially sunscreen) for me
This is a whole gem of information. Dr. Idriss literally summarized months of my research digging on the internet preparing for my skincare routine and added even more to it. She’s literally an angel.
Niacinamide, Vitamin C and Suncreen is my daily morning trio!!!! ❤️❤️❤️
same here, wonder if it is the right order. atm I am using Kielh's 5% Niacinamide, then Sunday Riley vitamin C and followed by Sunscreen
Is that the order it should be in? Idk if it should be vitamin C first or not?
the biggest issue with combining actives is that skincare brands have become obsessed with releasing products with high percentage actives, when in reality you dont even need that high of a percentage. a perfect example of this is the paula's choice 20% niacinamide, when all studies have been done with 3-5% niacinamide. (and all that costing like 50 euro's??)
Not to mention that higher concentrations of these ingredients are irritating to some people's skin.
That's a fair point... but just because there is not a study analyzing those % doesn't mean those % are not effective, and the other way around. It's just that there's no testing.
Also there will always be someone potentially irritable at any %.
Maybe 20% is added but the other ingredients in the product dilute the final content?

Such a good, informative vid. (I love that your husband is just chillin in the back)
I love how chill your energy is in this video
Thank you again and again for your informative, educational content. I’m learning so much from you, and in the process, enjoying my skincare routine more and more as I learn to understand it more deeply. I am so thankful we all have a professional like you to help us create the right order in our heads regarding this important ritual, aka skincare, in our lives! You are amazing! Thank you 🙏🏿❤️
Love your channel. So informative and concise for what's out there in the market when it comes to skincare. I appreciate you don't sugar coat products and are specific to what they can and cannot do for your skin. Keep educating us consumers. Your a phlepher of information and I appreciate that!
I just want to thank you for your channel! I have taken so many of your tips! It has been a major game changer for my skin! ❤
“Listen to your skin!” Best advice ever. Then Dr. Shereene takes it further. 10 out of 10! Thank you
Thank u for this subject! There are too many YT channels that tout actives but do not explain how to safely incorporate it in a routine. So much appreciate to you for your guidance!
I wish I could like this video a thousand times! This is invaluable information for anyone trying to understand how to properly take care of their skin. You are a SAINT! Thank you so much Dr. Shereene! Hugs from a Brazilian fan :)
Loving the more authentic feeling presentation in this one
You are literally answering all my questions and concerns, I appreciate you sharing your knowledge!
Im so glad that I found ur channel! It is always more secure to listen to a professional like u when comes to skincare. U are so cheerful, straight to the point, & ur content is not difficult to understand. Thank you so much for making all these videos ❤
You’re a Master, Doc, straight to the point in a very clear way! Thanks again as usual! ❤️
Hello Dr Idriss! Thank you for always putting on high-quality content that's informative and fun! I've been following your channel since last Spring and can safely say that my skin has never looked better. THANK YOU SO MUCH ❤️❤️❤️ Best wishes from Bulgaria
This one of the most helpful skincare videos I’ve seen (and i asked this question on a previous video-so thank you!!)
Thank you so much! I was 100% confused about this topic and I needed this! Thanks!
This is the best video ever to resolve all my doubts about skincare and ingredients THANK you!
I so appreciate and thank you for your knowledge regarding all facets of skincare and what's good and damaging for us individuals who ( let's confess) are pretty ignorant when it comes to choosing a skin care product and using it effectively for what it was manufactured to do in benefitting our skin. You make it easy to understand! Much appreciate your weekly vlogs. Keep em coming and we'll keep watching!
This channel is da bomb. Finally saw a cosmetic dermatologist for the first time - they had nothing to change about my skincare routine/products and I credit that to you. LESS IS MORE.
This is a whole gem of information. Dr. Idriss literally summarized months of my research and added even more to it. She’s literally an angel.
Literally?
Thank you for such great information. Your skin is looking better and better. I cannot wait until your products come out!
You know he is absolutely adorable ! Even from a distance. Thanks for your guidance!
So glad I found you I have so many questions and here you are answering them !!!
You are my absolute go-to for no B.S skin care advice, Dr. Idriss. The beauty space is soooooooo over populated by influencers peddling snake oil with no skincare expertise whatsoever. Grrrrrr. You are such a breath of fresh air and your knowledge is supreme. Thank you!!!!!!!
You’re wonderful - thank you! Started to take care of my skin at 69 (yikes - I know!) and at 73 it’s better than it’s ever been albeit aging. You’re advice has been on point for me and you deliver it in such a wonderfully personable way. Again, thanks!
I started at 50 and it's never too late. It is probably the only thing that I have been fully committed to for over 2 years. I just went on a cruise and my skincare had its own bag.
Clear concise and practical advice. Your patients are lucky to have you in their lives. As am I 😊
I love how real your videos are with your husband in the background! Love the way you describe skincare in a simple and easy to understand way! 😍🙌🏻
You’re the only one I would listed to about skin care. You’ve saved my skin ❤
Thank you, Dr. Shereene for sharing all these information. I greatly appreciate it.
Dr. Idriss, you are an absolute QUEEN! Thank you for sharing your knowledge here! Truly the most valuable skincare channel!
i love how you explained all of this, i learned so much without feeling overwhelmed. thank you so much dr. shereene!
Thank you so much for everyting you do. I look forward to Saturday moring each week because I know I always learn something new. It's the way you explain that makes it not only very informative but also easy to understand. 🌷😊
Love your videos. I am an esthetician and love skincare. I love combining mandelic and vitamin c. It has helped my hyperpigmentaion so much. I use during the day, I also did in the evening aha glycolic with 2% hq for only 3 months and my skin really looks great! I have always also done vitamin a and cycle between retinol, retinoid,retinyl propionate
Love everything you talk about! You turned me into a skin nerd!❤
Once again you've explained everything perfectly...you're the Best. ❤
OMGEEEEE. So much great info here - need to go back and watch again and take notes! Thank you!!
I just subscribed and binge watched so many of your videos! U post so much I'm so happy! These are great keep them coming!
You are looking extra STUNNING and GORGEOUS today! As always, thank you so much for these videos, you are so good to us! Love the science, facts and lack of BS in your videos ♥️♥️ Have a great weekend, you deserve it!
Agreed. I have to go back and watch again as I was just mesmerised by her beauty instead of listening and taking notes. ❤️
Good morning dr. Shereene, thank you for your education and I love your glowing skin today and God blessing you and your family 🤗
So glad that I found you. I’m into skincare since 2017 and still learning so much from you.
Wow… years of knowledge
You have kept me from destroying my skin! Thank you! 3 months of work and my skin is beautiful! I can finally go make up free!!! I feel amazing. Thank you! Thank you! Thank you!
Oh my gosh, i’m fangirling! 😭😍 How can someone be both extremely beautiful and highly intelligent? Can’t help but smile throughout your video.
Absolutely love you and thank you for explaining us so much for our skins...
Very excellent video. Dr. Idriss! Thank you.
I've added retinol into my routine and will never look back! no need for make up anymore. i used to use toners, bhas, masks, every product I could try, and it was way too much work. the retinol does what all those products do in 1 step. so happy
Your husband had me laughing so much! Thanks for the fab information!
Thank you Dr. I love your informative videos. Please keep up the fantastic work!🥰
This was fantastic content and very practical! Thanks!
im so glad i came across your channel. you are an angel
Very useful information, as always!
Thank you for this incredible video explanation of actives! It has helped me so much!
This video was so instructive, thank you!
I’m so glad I found your channel ! I can’t stop binge watching then as well as learning a ton of useful info . You make me laugh quite often as well , and your husband in the background this morning real life and very funny 😆
This was wonderful! Thank you so much!!
Would love to see a video for safe skincare to use during pregnancy for ACNE prone skin! 💕💕
You’re so informative and soooo beautiful! Thank you for existing
Thank you! Your overview really helped me navigate through this. Xoxo
Thank you so much for this highly informative video! Much appreciated! 🥰
Love these tips 💜
Thank you! This was really informative.
Amazing information.Thankyou Doc❤️
excellent advice as always - thank you so much for keeping going to educated us! I wish you had a clinic in the UK - if not, then I will have to get to NYC soon ..
Thank you so much for this content! Sooo informative! I will definitely go back to this video of yours when trying out a new active (or even an inactive). 😊😊
Very helpful. I was told that using glycolic acid and retinol in the same routine cancels out each other. Finally, got an answer to this question. Thanks for the educational video!
I sometimes combine glycol acid and retin a in the evening with no side effects whatsoever. Works great 👌🏻
You are the best! I watch you cos I love your beauty skin care guidance
Omg i was just searching if mixing vit c and niacinamide is okay. Thank goodness i found youuuu
I have recently discovered you and you are becoming one of my favorites. Great video and y'all are hilarious at 2:07!!
Thank you as always. This was very helpful indeed
Lmaoo at your husband trying to hide himself by holding the sheet in front of his face 😂😂
Thank you for this informative video!
Dr. I dress you are the best. I never miss your videos. Thank you I have learned so much from you.🇨🇦🥰❤️
What a great video. I can’t wait until your skincare is available. And I’m really looking forward to my appointment with you in October!! And did I mention how absolutely beautiful you look! Someday can you give us a peek into this makeup look? Love it all. Thanks! 👏🏻🙏🏻💄💛
This is a great video. I was taking notes. Such a nerd.
Excellent, informative and you are sooo classy….soothing as well. Others bring in Pop Ups….totally a distraction from the great info and YOU! ❤ thank you! So refreshing…💫🥰💯🌹🦋
this is your best video (and I have almost watch all haha), thanks so much!
Thank you, Dr. Shereene Idriss ❤❤❤❤
Thank you so much for this video. All the best 😊
Great content as always! Also, i like that kids and husband are aloud to be in the background. Keep inviting them Doctor.
OMG. White suits you wonderful! Thanks for all the knowledge!
This is the BEST video on this subject to be honest. I have had the absolute worse cystic acne from trying out a retinol product from a unreliable company and my skin has constant breakouts of acne since. I’ve been using the la Roche acne line but haven’t seen much improvement.
So! The last 4 days I have been using the Cerave Hydrating Cleanser, Olay Vitamin C Serum, and the Cerave Moisturizer and I can’t believe how a simple routine has improved my skin in such a short period of time!
So my question to you!
I just bought a cerave resurfacing retinol, Ordinary 5% AHA, and the Paula’s Choice 2% in hopes to marry them all together one day for absolute perfection. How long should I wait before introducing one of those at a time? 😫 I’m so impatient but don’t want to flare up my skin. Thanks so so much. ❤
Thank you for this clear explanation!
Dr. Idriss,Thank you for this. You made it so clear and easy to understand. I was drawn to your channel because of how beautiful and flawless your skin is, and I thought to myself that you're a living example. If I want to learn anything about beautiful skin, I'd better listen to you lol.
Ah. This is what I was looking for. I have no problem combining Tret and AHA (Alpha H Liquid Gold) on the same night and the DERISION I have received about this. THANK YOU 🙏
13:44 - That's me. I just use everything lol. Benzoyl peroxide wash (twice a day), BHA (twice a day), glycolic AHA (night time), tretinoin (night time). I also apply everything to wet skin. Have for years without any issue at any point ever. Right now I'm pretty sure I'm going to add niacinamide, too (for the time being).
This content is amazing, thank you so much!
aaa so happy to have come across yer channel. verh informative. thankyouuu.
I think a lot of the challenge is that these "basic" cleansers, moisturizers, and sunscreens, have actives in them, but they're hidden in the "inactive" ingredients list. The basic Eucerin Moisturizing Sunscreen has Lactic Acid in it! I don't want that in my sunscreen, I wanna use it at night where it's not as big a deal if it makes my skin more sun sensitive! I spend way too long just reading ingredient lists at Walgreens just to leave with nothing :(
If lactic acid is very low on the ingredient list it is a pH adjustor not an exfoliant :)
@@kategolden8840 It is also a humectant at low levels. Fructose, Glycine , Inositol, Lactic Acid, Niacinamide, Sodium Benzoate, Sodium Lactate, Sodium PCA and Urea combined at EXTREMELY low levels are added to many cosmetics via a humectant mixture sold under the brand name LACTIL®
Im sooooo gladdd i find youuuuuuuu doc ❤.. Nooo more searching in TH-cam for confusion.. New subscriber. 🎉🎉
Super helpful video! Thank-you!!
Thank u so much, u truly are the best! I have learned so much from you and I just discovered ur channel a week ago!
Love your content. Thank you. I'm hoping you can do a video on razor bumps and ingrown hairs someday. Treatment, prevention, and getting rid of the scarring. Glycolic acid and Benzoyl Peroxide seem to help but I'd love to hear your take and see what else to do!
Great information! Thanks ❤
Oooooooooh I been waiting for this!😍
I hated all those skincare videos of people that use 20+ things in irregular steps and be like- you're not meant to put these togetherrr.. or the sunscreen and 2 steps later a facemask 🙈
Thank you Dr. Idress. Turns out I’m doing everything right. Why? Because I’ve listened to you and taken your advice 😊
Hi Dr Sherene, hope you are doing well. I cannot emphasize enough how grateful I feel after discovering your chanel. You have helped me understand my skin better and choose products wisely rather than just buying everything that any influencer suggests. I truly appreciate the time and effort you put in for these videos. I always look forward to your videos every Saturday. Love from India ❤
Lastly, I would be thankful if you could discuss about 2 topics in your upcoming videos-
1) Could you suggest how to treat corn and calluses, my foot skin tends to be very hard so I am curious/worried to know about it.
2) What would be your approach in treating melasma in people with skin of color.
You look fantastic tonight, I love your channel❤️
