I love when top doctors like you talk about cheapest options or drugstore products for poor humans like me that dont wanna get old. 💐
❤️❤️❤️❤️
In the I bought expensive products just because I believed they were worthy...big mistake my friend
Search for the budget dermatologist she’s great at recommending affordable skincare products with good ingredients
Getting old is better than the alternative
Was writing notes, thought you guys might appreciate them
Exfoliate with acids at night
AHA
-water soluble
-dry skin. anti aging
-make you photosensitive
-draw in moisture
1. Glycolic (smallest)
-great for aging and cell turnover.
-Collagen production. Supports dermis
-goes the deepest
~10% Revitalift by L'oreal
2. Lactic (middle sized)
-helps mostly with brightening
-less irritation than glycolic
- Pregnancy OK to help with pigmentation
~Sunday Riley Good Genes
~kate somerville ExfoliKate
3. Mandelic (biggest)
-fat soluble
-Both water and oil soluble
-Good for oiler skin
-good for pigment prone skin
-anti aging benefits
-good for post inflammatory hyperpigmentation
We appreciate it. Thank you 👏🏽😃
Thank you!
Can I use ALL of them??
Thank you so much for writing this down for us❤
Thank you!!! Do you know what she’d recommend for exfoliating?
Aww thanks I was just doing the same thing
Thank you so much for the series. I am 51 years old and just now starting to introduce acids into my skincare routine. I really needed this 101 course. Wishing you a speedy recovery.
I get laughed at for wearing sunscreen in Ireland . Everyday factor 50 from krave beauty and I use their AHA . Thanks for the video 🥰
I love Krave Beauty’s SPF too!
I visited Ireland and got sunburned the first day. I think the locals were very impressed lol
@@MalenkyGoblin haha ya you see that when visitors come back from the Aran islands . There’s a wind ,sun combination here .
@@MalenkyGoblin one of the few times I got sunburnt was in England. People always laugh about that as well... 😅🤷🏼♀️
@@leonamay8776 As an English person I have one question... HOW?! Everyone knows there is no sun in England haha!
Would love a video on what products you can wear together. I'm always so nervous about layering products. I've built up my skin to be able to use retinol every night, but now I don't know when to use my acid exfoliant. HELP!
🤓 noted! And will work on it
Me too! Specially what not to mix with biologique P50 or with vitamin C
Me too!
Yes! I am so confused when to incorporate my glycolic acid serum with my nightly retinol use. I love learning about this stuff so much ♥️
I use pixi glow tonic only at nights, and didnt know that Glycoliquie Acid is actually AHA! Thank you. And, yes would be very helpful to know what to mixed, what not to mix, layers etc
All your videos have been so helpful in refining my skin care routine! My husband even noticed and keeps telling me I look very "fresh faced", which says a lot because he doesn't notice things usually. haha I used to just do cleanser, toner, moisturizer, but have started to incorporate exfoliants and it's just made a tremendous difference!
I'm literally sitting with a notebook, a pencil and markers and taking notes while watching your videos. They are so informative! Also they help me A LOT to understand ingredients used in skin care, so I can invest my money in a smart way ( instead of burning it😳).
Thanks Shereene 🙏🙏🙏
Love this video idea and that you’re providing somewhat affordable options. More drug store picks would be amazing. Or low high-end products at least.
Ok on it!!!
I feel like I’m attending a very interesting class everytime I watch ur videos, thanksss for sharing the precious knowledge with us 💗
So excited for the BHAs 😄
🙌🙌🙌🙌
You are so mesmerizing to look at and listen to! Loved the video! As someone with super extra dry skin, this was definitely educational and gives me so much insight into chemical exfoliation! Thanks a lot!!
Dr Shereen, I'm not black and yet a 5% glicolic acid gives me a tanning effect next morning when I wake up before even going out. Dr Vanita Rattan is not a dermatologist, but she is a skin care formulator who specializes in skin of color. She doesn't recommende glicolic for people who tend to tan. I think it is working for you because you are very fair...
You might be the most underrated channel on TH-cam, can't wait to see you amass the first million subs! You deserve it
When it’s Shereene I like the video before I watch because I know I’ll enjoy it ♥️
To answer the question about glycolic acid and darker skin tone, I heard that info from a youtuber/cosmetic formulator that runs a hyperpigmentation clinic (Dr. V Rattan).
Heyyy doctor, can you please talk about chemical burns and how to sooth your skin afterwards. Thankyouuu 💕
Will do ❤️
I’m a qualified beautician and I have to say you give amazing skin care advice and I love your channel!❤❤❤
Great info, thank you! Could you do a video in depth how to layer, who goes first etc...
Do you have a video on tretinoin? If not, could you do one? When should we use tretinoin vs the acids you mentioned?
tretinoin is a retinoid, not an acid
@@a.s.9215 I know. I am asking when Tretinoin should be used and when acids should be used.
Definitely use them on alternating nights and not together--they are heavy hitters and deserve their own night. A great night time regimen would be one night retinol the next night glycolic.
@@a.s.9215 Tretinoin is also called retinoic acid. Although it does not need a very low pH to work like vitamin c or aha.
@@a.s.9215 girl chill she’s just inquiring
Thank you for providing an easy to understand explanation of AHA’s! I've learned so much since following you on IG. You have a student for life. Stay well! 💕
There’s a brand here in Brazil called Creamy, they have amazing Lactic, Mandelic and Glycolic acid products for something around 11 to 13 dollars (I have all of them in my collection). I apply Mandelic or Lactic every night and Glycolic once or twice a week, my skin very resilient (to the point I can use retinoids every day and don’t even get a tingle) and it’s so much glowier after I started using them.
Hi Dr. Idriss, thank you so much for your videos. Greetings from India!!! 🙋
Learnt so much from you regarding these acids since Indian cosmetic industry is now raging with multiple acids and we all fall for their marketing. Kudos on that Hyaluronic acid video btw!!🙏
Just a suggestion. If you could also mention the acid % for the right amount of exfoliation then it would be great. Since these products are not available in India,it's difficult to find the right kind of product that would match the efficiency.
Thanks again!!
I was definitely looking for something like this, just love it! is the exact explanation everyone will understand. I just need to know which one of them should I use for my specific skin type so please help with this Dear Sereene. Love you from Ecuador (the middle of the world)
I love your videos, so honest. I have the Dr Gross’s and I use it maybe once a week or 2. I thought it was crazy to use it everyday. You confirmed my thoughts. ❤️
You have the most gorgeous skin I have ever seen in my life 😫😫😫😫😫🤩🤩🤩🤩🤩🤩
I often read that acids are deactivated if you apply a moisturizer right after, because the acid needs a low ph to do its job. However I find it quite drying to leave the acid on for 20-30 minutes. Can you explain whether it is really necessary to wait?
I definitely wouldn’t say that’s necessary depending on the products. Leaving on a serum or a toner until it’s dry should be sufficient. Only thing you don’t want to do is layer a serum or moisturizer before using an AHA or BHA if you’re looking for maximum effect. Also with AHAS you want to avoid formulations with oil or serums contains oil before hand. AHAS are water soluble acids so oil confuses them, which will give you inconsistent results. Hope that helped. :)
You could look into AHAs in cream formulas that contain emollients and occlusive ingredients.
@@maxbaltz2490 Could you use a moisturiser with oil AFTER applying AHA?!
i love this type of educational content. please make more about skincare ingredients!!!!!
How many times a week should we exfoliate if we are using tretinoin?
Good question! 😀 hope for an Answer
Zero.
Hard to give a one size fits all, but I use .025 Tretinoin every other night and then exfoliate 2x per week. I have dry skin and some acne, but my main concerns are dryness and PIH.
I use tret gel 0.05% five nights a week and exfoliate with an AHA twice a week. If I feel like my skin is feeling raw/irritated, I take a night off from all actives and just make sure to moisturize really well. Just make sure you pay attention to your skin and always be on the lookout for any signs of irritation. If you want to incorporate an AHA or a BHA, just start slow; once a week.
Hi Shereene!! My name is Haley and my question is, should I use a glycolic acid exfoliant if I already use vitamin C and retinol in my routine? I'm struggling with some lines on my neck and decolletage and would like the glycolic acid to also help to give me a glow. Thank you so much!! Love you and your videos! I hope you are healthy soon! ❤️❤️❤️
😍 i love the farmacy honeymoon glow serum. Always wake up with smooth skin and later realized the majority of that is AHA which looks to be the reason. Thanks for the video!
I invested finally in glycolic acid face wash. I'm scared cuz I see so many people saying women of colour it's not good but I'm gonna follow your advice haha.
Love you and your videos! So much information and so clear! Love to see a cheaper and a more expensive option (obviously only if you actually like the products)
May i ask your eyeglasses’ brand name? Love it!
I just have to say that you are beautiful! I love the way you talk too. I would have loved to have you as a teacher! The way you explain things makes sense, is easy to understand and fun to follow.
what a great, clear breakdown of acids. Thank you! Do you like the Ordinary formulations? They have all these acids available. I have personally tried their Mandelic and Lactic acid and really liked both products.
what does it do with your skin
I loooooved this thank you Doctor! How often do you use that L’Oréal glycolic? Every night? Every other? Also where in your routine? :) ❤️❤️
Another fantastic video of yours Dr Idriss 👏 😀
And can I say,you look absolutely stunning 😍
Dr. Shereen, thank you for the awesome video! Can you use vitamin A after using the glycolic acid serum?
I probably wouldn’t - as you’ll get very irritated
Can you do body care routine? Thank you
Still waiting for a sebderm vid!!! I hope you are feeling better by the way!
🤓 taking notes
Thank you for this amazing video! Could you make a video on the difference between or what works best, is the cleansers of serums?
As well as, in what order should we apply (if allowed) the rest of our nightly skin care routine. Thank you 🙏🏻🥰
three are the must cleansers, good serum and sunscreen. apply from the most watery to thicker if u u go multiple layers. am sunscreen is last
Great short video and straight to the point❣
Please do video about retinoid.
loved the video it has helped me more than any other videos on this topic to choose what might fit for me
Emme Diane makes a great mandelic acid serum that is cheaper than the Allies of Skin one. It’s called the clarifying serum if anyone is interested. As Dr. S said, it works great if you’re acne prone.
Thanks for explaining this! And for posting when you’re sick. Wishing you a quick recovery.
Facetheory has great products, with amazing price point. I'm in love with them!
Thank you for this. Concise and good information we all can use. More videos please! Love you!
Thank you for the quick run-through. I enjoyed it.
First: thank you and you are awesome!!!
How often would you use the Sunday Riley or L’Oréal serum in a week? (Maybe alternating with an otc retinol?)
I've been using glycolic acid as of last week and I see a huge difference in my skin. I am hoping this helps with my hyperpigmentation from my acne.
Don’t forget to wear the sunscreen!! Which glycolic one r u usin?b
I am using the ordinary glycolic acid toner at the moment. I am a sunscreen snob at the point in my life ☺️
@@melindamedina3673 I just started to use the same product 👀
@@melindamedina3673 Hi, can I use this toner around the eyes? I hope
only a week ,? and r u using it too w others, good for u, do u use it daily i use it every other day for about two weeks too but i notice as if im getting uneven tone more than before i use sunscreen everyday. i only use it with hyaluronic and bakuchiol with substantial time after the glyco and hya, when i use glycolic . lastly muisturizer
I use the Ordinary’s Lactic Acid with HA and it’s really inexpensive.
I love this one, I use it on my elbows, knees and bum too! Silky smoooooth
Thank you love these so much & glad to see you are doing well!
Is glycolic acid effective for anti-aging in face wash form if you leave it on a few minutes before washing off?
thanks for the vid! loving this format!
Dr. How about a review of the ordinary or deciem products. Its really popular specially price point. The inkeylist as well. However many people use them incorrectly.
I use the cosrx AHA 7 whitehead power liquid and my skin never looked this good ever. It looks healthy. Alhamdulillah 🥺
You are just simply an AMAZING WOMAN!!! ❤️
Short and simple, love it
Hello Shereene, thank you for this video and all your explanations ! It is so refreshing to find good and trustful advices on the internet ! Could you make a video about sunscreen ? Also, if you work in a basement, with no daily light, should you wear sunscreen? Can the artificial light damage your skin?
I love you! If borders weren't closed I would come and see you from France. Could you please make a video about under-eyes wrinkles? I'm only 40 but when I smile I look 75. It's all crinkled 😢🙏
Please consult a derm n start using tretinoin
@@shejar Hi, can you use acids and tretinoin around the eye area? Hope to hear!
Could I have a PowerPoint of this? 😂 you’re so good at explaining clearly what is what. Of the AHAs, would then be better the lactic than glycolic for sensitive skin?
Lactic. It's mid sized.
Mandelic is even milder.
(and there are also PHAs)
Thank you for your educational video. I also appreciate pointing out product ingredients and providing budget products not just expensive ones. Can you do a video on glycolic cleanser effectiveness and talk about difference between cleanser and glycolic serums? Thank you.
Wishtrend has a super affordable 5% mandelic acid solution with lots of other amazing ingredients. My sensitive skin loves it! Xx
I want to hear your review about the ordinary. Love your videos, very educational and had helped me understand my skin way much better.
Man!!! I need to go see which of my products have glycolic acid in it 😅
7:25 LOL OMG, loved it!
Thank you!!! That was so educational, love it 😍
Thank you!!!
Thank you so so much for the great videos!!!..I'm addicted to your channel. I was just wondering whether or not it would be safe and a good idea to use glycolic acid while also using an LED face mask (I bought the one from current body as you suggested)? And would one use the glycolic acid only on the face or is it safe to use also on the under eyes? I have quite sensitive skin... Thank you in advance for any answer that you might be able to give me :)
Thanks so much for sharing! I love this channel. I'm just wondering how come you recommend Loreal products and then Sunday, Kate Summerville etc? I would have never thought a skin expert would use Loreal products, is the formulation really good? thanks
The video is so educational, LOVE IT!
I have a question, in some countries, like mine, l’oreal does not sell the glycolic acid that you show in the video, instead, they sell the peel-pads, do you think they are good as well?
Thank you so much for these videos I love them so much 😍
Thanks for the informative video!
I use (only at night) this HYFAC global care, for like one month now and it seems effective (for my mixed skin that tends to break out).
It consists piroctone, olamine and glycolic acid (among others).
Dr. Shereene Idriss! You are one of the best because you are beautiful, female, and Smart. I enjoy your videos. Thank you!!! And I would love the video about keratosis.
Hi Shereene, Love all your videos!! I have a question would you recommend glycolic acid for someone who has sensitive skin? Im thinking of getting the Loreal paris one.
Hi Shereene! Thanks so much for this very informative series. You got me hooked! Could you share your thoughts on the URIAGE K18 cream? I'm curious to hear your thoughts as it is supposed to be a combination of AHAs & BHAs. Hugs from Belgium!
Thanks a lot for this fabulous channel! I 've been using Neostrata 15 for many years, but I'd like to try tretinoinenow I'm turning 43.. is it possible to switch without getting huge irritations?
I have sensitive skin and I was wondering is it ok to apply lactic acid serum and leave it on for just 10, 15 minutes and rinse it off like with some stronger serums instead keeping it overnight? Will this do the job and how long should I keep it on. Thank you very much
I didn't realize wearing sunscreen everyday also helps you get the best effects and outcomes from ur aha's and bha's, until as like last year or so
Better now than never!
@@shereeneidriss right!! ..all those years baking in the sun when I was younger😂😂
I’ve heard a log of mixed feedback on this: if I’m wearing my IT cosmetics CC cream almost daily that has spf 50 in it, do I still need to apply a sunscreen? Love the knowledge and facts you’re spreading! ❤️
Ofc you need the cc from it are not enough because sunscreen you need to apply 3 fingers tips amount. You are damaging your skin.
Dr Shereene - I use an aha/BHA serum, what am I suppose to put on after? And what to avoid? I usually use a moisturiser with b5.
Love this video!! Where is your bird necklace and sweater from? Adorable!!
I’m curious as to why you say avoid Salicylic acid if pregnant. Case studies have shown that there’s very minimal systemic absorption so it would be highly unlikely to cause issues. I’m just wondering why you recommend lactic and glycolic over it?
Hello Dr Idriss😃I have a question about Mandelic Acid.I am using the Mandelic Acid Treatment product of The Inkey List - as it's the only product that's available here in my country and apart from that, it's the only one that's affordable - and it states in its product description that Hyaluronic acid must be used beforehand. Is it really a must? I already know your point about hyaluronic acid but I just wanted to ask just in case. As a college student who can not visit a dermatologist often,I really benefit from your videos a lot even though, 99% of the products you recommend are not available here,at least they help in terms of ingredients.Thank you very much in advance.Hope you can reply back🤞Take care😄
Can you do a video about fungal acne? I tried almost all of the products and avoiding products that are not fungal acne-safe,still, they are still there on my cheeks
If you’re looking for lactic acid try ameliorate transforming body lotion it is epic for dry or chicken skin
I've had good experience with Amlactyn, which has lactic acid. The only problem is that, when I use it on my body, my cat gets obsessed with licking it off my arms! 🤣🤣
Glycolic so good and latic acid really like it. Sunday Riley in the pricey side but good
YOU ARE SO DANG HELPFUL!!!!
Hi Dr. Shereene, is it advisable or safe to use glycolic acid and tretinoin at the same time or should I alternate the products?
I currently use pha on my cheeks and bha on my t-zone once a week because I'm pretty sensitive (I have some rosacea) but also acne prone. Maybe I'll try a gentle aha, like the mandelic, sometime when I'm sure my barrier is healthy.
Hi!! What are your thoughts on naturally derived AHA (products that contain sugar cane extract for glycolic, apple extract for mandellic, ect)?
Love this video, was just wondering can you use lactic or glycolic at the same time as azelaic ? Like everyday ? Or just a few times per week
Would you agree there’s no reason o use AHAs in the morning? People have asked me, can’t I use it in the morning if I put sunscreen on after? Like, sure, but why not just use it at night?
Loved this educational video!
Someone new to these acids…how often would I use when beginning? Once a week? Dry, slightly sensitive middle aged skin 😉
How often do you use the L-Oreal glycolic acid? Is it every night or more like once a week?
A loreal video seemed to say it could be nightly
I was glad you mentioned L'Oréal bc it's one of the products I can find more easily in my region. But then I saw its got sodium hyaluronate, which I started largely avoiding bc.. of you 😊 means I have to start looking for another product
may i ask why? s hyaluronate
Not acid related but since you encourage wearing sunscreen so much, I’m wondering if babies (11 mos old) should wear it even if they’re only inside? But there are lots of big windows in the house.
I’ve looked through your videos, would love to see what you think about Ren Ready Steady Glow AHA daily toner. And how often you think it should be used!
Thank you , doctor ❤
🙌❤️🙌❤️
Hi!! What exfoliators would you recommend for combo “sensitive” skin? :)
Hello,
I have combo sensitive skin and my dermatologist has recommended the ACM SEBIONEX.K (15% aha) and it suited really well
