[@annc9850]

This would be super cool. I’m joining you on the request 😬😆♥️.

[@judyh3707]

Doesn't she basically promote the same level of care for people of all ages? It seems kind of ageist to promote that someone who's older ought to treat their skin differently, because there's an underlying implication that aging is bad. I don't think that is the intention of the question/request, but cosmetic companies already do enough of that.

[@bernadineroyal6656]

As a mature woman,I can say that my skin is so much different then that of my 30 years daughters skin. As the aging process is different for everyone, in general , it’s good to know that, some of us over 50,don’t have the same concerns as that of a 20 or 30 year old. It’s not be ageist or anything,it’s just good common practice as a derm to look at the age of her patient. To consider the concerns they have and do what it’s right for that person. I’m sure there are those of us over 50 who have hormonal breakouts,have become dryer due to lack of hydration ,who haven’t used sunscreen in the past and have pigmentation concerns. These may not be the same as a younger person but the derm can address these concerns as the same as the acne concerns of the younger patient. All the best to you 😊❤️🇨🇦.

[@bof224]

yes!

[@izzie9526]

I was dealing with bad acne around six months ago. I heard all the rage about salicylic acid and overdid it once, especially with my sensitive skin. I had chemical burns, pus-filled blisters, just destroyed my skin's barrier. Scarred me both emotionally and physically, so I now stay far away from any salicylic acid. Yes, I know it's an irrational fear lol. But then a few months later I started getting flaky skin and my products weren't absorbing, so I took a very cautionary step into the realm of acids once again, this time with glycolic acid. It worked well to exfoliate and reduce blackheads without turning my entire face red in 10 seconds. I've worked up to using it once a week, and my skin is so soft and my products absorb much better. But yes, let me be the cautionary tale. I still have a pink scar on my nose from where my skin sloughed off...not fun

[@Jasmine215100]

Could you have been allergic to the ingredients of salicylic acid?

[@Iflie]

I don't doubt it's possible but it sounds like a big concentration. Some acid peels really do work by burning the top ;layers of skin of but I've used salicilic acid daily for years and it just helped. But it was a product for daily use. Puss filled blisters also sounds like it might be a massive allergic reaction.

[@denisewittmann3233]

I do use The Ordinary Peeling Solution, but infrequently. The directions are pretty clear: Do not leave on for longer than 10 minutes. It is not recommended to use more than twice per week. Contact of the product with the skin must be of limited frequency or duration. Sadly, it is people who do not read or follow the directions who are messing up their skin 😪

[@cmntr_]

It's also very personal. I can't handle 5 % glycolic acid oder 2 % salicylic acid more than once a week, and I've been using them for years and I wouldn't consider my skin sensitive. Start small, patch test and use your noggins, people ;)

[@ItsBlackSheepVision]

For beginners even less frequent. If I ever purchase it I'll only use it once in two weeks. Also like the other commenter said: patch test first inside your forearm ‼️‼️

[@cv7958]

Even twice per week is quite aggressive given it’s percentages. I think this would be best used in rotation with a more gentler exfoliation treatment e.g., 1x a week use The Ordinary AHA/BHA treatment; next week use 1x a week First Aid Beauty Radiance Pads etc.

[@judyh3707]

If it hurts your face, STOP. Whether its working or not, pain is not a good thing.

[@lindseystein9676]

I love that product. With a lot of trial and error, I’ve found that using twice per week for 6 minutes is the best for my skin. The 10 minutes was a bit much for me, even once per week.

[@PeachyCat-3990]

Thanks to you I stopped exfoliating everyday. For about 8 weeks I didn't use any actives at all to help my skin repair; now I only use BHA a maximum of twice a week, sometimes just once. Skin looks much healthier so thank you

[@ayeshasharif4874]

I was feeling down.. and then this came up, thanks for cheering me up and teaching me at the same time.

[@marikal2341]

@@shereeneidriss I use Cosrx, AHA/BHA Clarifying Treatment Toner in the morning before Timeless C-serum as I've been told it lowers the Ph and makes the vitamine C work better. I top up with Spf 50. My face seems to handle it well, but my neck freaked out, so stopped using it on the neck. Now I wonder if using the toner at night would be better but nights are adapalene time... so 🤷‍♀️

[@OccianoDanica]

Dr. Idriss’s advice on washing in the morning w/ just H2O is doing my skin wonders. I thought I have an oily skin but weirdly enough my skin produced lesser oil now. And exfoliants are really our bffs but dermatologist don’t trust us to DIY because we always overdo it. Lol learned my lesson once when I got my face raw and inflamed. Keep the product longer on skin DOES NOT EQUATE to faster “exfoliation” ☝🏼

[@ihatecatsandbunnies5853]

I use a micellar gel in the AM based on dr. idriss's advice. i used to think my skin would eat products because I was oily but I was making myself oily by washing my face twice a day

[@thanyasantacruz1070]

I started exfoliating last week. It is amazing how much one learns with you. Thank you.

[@BeverlySummers10]

Can I just say how much I thoroughly appreciate your skincare room? It fully caters to my skincare products obsession and ocd organization. I need one; like yesterday.

[@Blondie727]

Thank you for this. There was a woman in the “DIY skincare community” who was excessively using chemical peels & other exfoliants. She ended up looking much older instead of younger which surprised me. I thought of her as an example when you said over-exfoliating can make one look older. I too need to be careful. I use Retin-A at night & glycolic acid serum in the morning for skin rejuvenation. At times, I get pimples from doing so & now I know why. 😬

[@tinafeng9897]

I'm always re-reading the directions and ingredients whenever I do my skincare (especially when it's a face mask/clay) it helps remind me to do it the right way or what I should take from it. Thank you Dr. Shereene for this lovely lesson on chemical exfoliants - I'm learning a whole lot more🤭

[@dianalaura8285]

Thank you so much for this video. I've tried to say these things for quite a while, ever since I've noticed this idea of using efoliating acids every single day, twice a day, even in a single skincare routine, and the companies, influencers and bloggers jumped at me, saying I'm spreading fake informations. I was starting to think that maybe I'm the one who's crazy. So thank you so much for doing this video.

A few years ago I had spent the summer on my boat. When fall came I realized that my skin looked leathery, like old shoes. I was using Paula’s Choice at the time so I called them for help and they recommended their 8% AHA cream and told me it would take awhile. Sure enough within two to three months I looked like myself again. So grateful to them.

Thank you, thank you, thank you! For someone with mature skin but very new to the world of beauty products. My staple for years has been sunscreen and moisturiser, this type of information is incredibly valuable. Thank you for explaining with great details the world of exfoliants. It makes it less scary for me to dip my toes in! 😊

[@tj28308]

Thank you, what a comprehensive, informative session! I think the reason why we're so obsessed with skin barrier health these days is because we all had wrecked ours with over-exfoliation at some points in the last 4-5 years.

[@Jasmine215100]

That and too much sun exposure in youth!

[@jenniferd264]

Your closet 😳 ❤😂 In my dreams! I use my acid serum 3x a week, at night after I cleanse and before my moisturizer. My daily moisturizer has a 30 spf so I’m covered the next day! Thank you again for putting this truly important information in simple, fun and easy to understand ways! You crack me up with your enthusiasm! I just wish I could afford more. Tho I am happy with my face (skin) At 60, I’m doing great. I have so few wrinkles and the few I have are so fine. I look in my early 40’s. I credit sunscreen, not smoking and genetics ❤ Tho my sister who is 2 yrs older smokes, uses tanning beds, refuse’s sunscreen and we look easily 20 years apart! She hates me and actively comes at me because of it! I’ve had to get a Restraining Order! (I’m not joking) our Mother is almost 88 and has so few wrinkles and sagging it’s crazy! She looks 70 and a healthy vibrant 70! I wish I could send my younger self flowers for using sunscreen like I did lol So I promise you younger ladies, your 60 yr old self is begging you lol wear that sunscreen! 😊

Thanks for this video! Hoping for a video/deepdive that tackles what serums can be used at the same time within a day. Basically serums that work well together and what doesn't (and what you can use after exfoliating!) Or maybe something related to warts/milia? 😊 I know the best option is going to the clinic but it would be nice to know what else can help (aside from exfoliating)

Thank you for everything you do, knowledge is power. The amount of misinformation out there is crazy. I went to get a Biologique Recherche facial yesterday. Told the esthetician I use CF Ferulic along with prescription azelaic acid to treat my rosacea. I told her at night I use tret 2-3 times per week and exfoliate 1-2 times per week with lactic acid. She went on to tell me I am overdoing it with too many different acids, and that she would suggest I stop using all that and instead use the p50 lotion daily morning and night because my skin is too dehydrated.....

[@stephaniebateman2637]

Thank you for clarifying how often to use acids! Marketing tells us to use them way too often!!! Anecdotally, I noticed my skin does best using acids 3-4 times a week, so thanks for validating what I'm doing.

Having mature, sensitive skin, I have been using Wishtrend Mandelic on the nights I don’t use my Avene Retinaldehyde and a few mornings I use the La Roche Posay Pigmentclar cleanser before my Vitamin C… seems to be mild enough… I tried the LRP glycolic and it was too irritating for me. Thanks for very informative videos!

[@MiladyToxic]

I just bought this product and used it this evening, the mandelic acid by Wishtrend! It made my face slightly pinkish red but otherwise no itch, sting, irritation. I will try it 1x a week for 1 month and see how that goes. Is it safe to seal this product with CeraVe Healing Ointment??

I really hope you see this because I ABSOLUTELY LOVE your approach, and your personality and the passion and knowledge you have for skin is just infectious! I have recently made the choice to swap out most of the skincare products you are recommending for hormone health as lots of the chemicals disrupt your endocrine system. Have you considered more natural alternatives, and would you be open to creating videos providing effective science backed alternatives - there are so many brands out there taking advantage of women that want a natural option who don’t understand the science terms and you could be so amazing at bridging that gap ❤️ I love you work thank you!

First off, thank you for the information! I have been using a toner for months and now know that I have been using it incorrectly. I picked up a Glycolic Acid (AHA) exfoliate toner, which I was using everyday or every other day after showering (for the past 4 months or so). After letting this sink in, I was using a Hyaluronic + Vitamin B5 serum, followed by a light weight moisturizer. I know... YIKES. These are products and actions of my routine I was following before I found your channel.... However, I haven't noticed anything poor or drastic changes to my skin. It's hydrated, not irritated and I don't think I have damaged my barrier as I wear Clarin's 50+ SPF UBV + UVA sunscreen EVERY Day without fail (it hydrates my face, no white cast, and absorbs well/goes on smooth). I am going to switch out my serum, but wondering if I should continue to use the toner as I have been? Or is it smart to dial it down... FYI I am in my early 20's. (Thank you for all of your advice, I am so glad I found your channel!)

I love lactic acid, and my go-to is the one from The Ordinary, 5%. I do use it twice a week in the morning, though. Always followed up with SPF 50. I haven't experienced any irritation.

What an interesting topic... Great video as always!

You guys, if you want to follow the ideal of washing with h2o in the morning but still wanna feel a little more clean-try good molecules rose water cleanser. It’s like one step above water but I need a little more than water if only to wash the sweat off my face (arizona). It’s soooo gentle.
