morning, my little nerds. I am Dr. Shireen Idris, and welcome back to Saturday morning Pillow Talk. So we've had a little shift in our scheduling where I was doing this every Saturday morning at 10 A.M. and then I thought to myself, let me spread it out to every other Saturday morning at 10 A.M. but then honestly, I just missed interacting with you guys on Saturday morning. So we're gonna do a long format video three Saturdays a month at 10 A.M. Just bear with me as I try to figure out this new flow of life. Having launched my office last year, a year and a half ago, and the skincare line a year ago, I'm trying to figure out how to wear all of these hats and do it all at once. But the reality is, my love for the community really started on Instagram and grew into YouTube, and I just can't seem to cut it down. This week, I thought, what better way to start the year than to give you guys my five golden rules on incorporating a retinoid.

into your skincare routine, and why is this fitting? Because today is my birthday, and with every year that passes, I am not one who gets depressed. I honestly, I'm just grateful that I made it another year. Like, we survived, and if we can survive while having better-looking skin as we get wiser in life. One of those ingredients that allows our skin to look better as we age in life are retinoids. Let us jump in, starting with rule number one, and this is the most important rule for anybody, whether you are a beginner or a veteran. Go low and go slow, meaning it's not just about the percentage. When I'm talking about go low, it's about the type of retinoid that you're incorporating into your routine. So, if you are a beginner, a moderate, or an advanced user, this applies to all of you. If you guys want a little refresher on retinoids, you can watch the Deep dive on retinoids that I did before, but briefly, retinoids are the class. Okay, it's the class of vitamin A.

that helps your skin renew itself and be stronger and better for you in the long run. But they're not all created equal. Tretinoin is that prescription, is that active form of retinoid that makes a difference in your skin. Retinol is what people know retinoids as and that gets converted into retinal which then gets converted into that retinal acid, tretinoin that's already active in your skin. But there's a whole series of events in between and even before the retinol. So starting from lightest, we have retinol esters and those are retinol propionate, retinal palmitate, retinal acetate and they are the least effective forms of retinoids but they're also a good entry point for people who are either very sensitive or do not know how to start. Then the retinal esters become retinol and that's what you guys are so marketed basically on the grand scheme of things. Beauty companies, beauty industry markets retinols and you will

hear this is 0.3 percent pure retinol, like the L'Oreal or SkinMedica or SkinCeuticals, because retinol has become the mainstream synonym of retinoids. But retinols are not active when they're applied to the skin. They have to get converted into retinols, and then that gets converted into retinoic acid, which is the active form, aka the prescription. So retinols are 10 to 20 percent less potent than retinoic acid. Um, again, they're good if you are a beginner and if you're super sensitive, and you want to go past the retinal Ester stage. Look for an encapsulated form of a retinol. Encapsulated simply means it has a little capsule around it that slowly breaks off throughout the day or whatever the timeline is, so the retinol gets slowly introduced to your skin. So it's a slow release. Then retinal is a step above the retinol, like I just said. It's a good alternative if you're

looking for more efficacy, but you're just not ready to take the plunge into a retinoic acid. It's more stable, and it is a gentle vitamin A derivative, but there is a better version than retinol now, which is also known as renoic acid esters. And this is the cousins, also known as hydroxypenicolon retinoate or Grime active retinoid from the ordinary. And this has been around now for a few years. It is the cousin form of retinoic acid, but it is less irritating. So, if you are somebody who you think you could take the plunge, you're ready to start a prescription, but you tend to be sensitive, this one's for you. If you're too scared to do a prescription, this one's for you. And if you can only tolerate a prescription once a week, but you want to have something more consistent in your routine, I would strongly suggest that you look for a retinoic acid Ester, also known as hydroxypenicolon retinoate. And then last we have renoic acid AKA.

tretinoin, AKA prescription that you need from a doctor, AKA the most effective one. But you do not need to go wrong and strong from the beginning. So, golo meaning go low on the type of retinol and go slow, meaning slowly incorporate it. Start by using it once to two times a week only for a few weeks and slowly add a night three times a week for a few weeks and slowly add a night four times a week for a few weeks until you can use it every night. Now, there are some people out there who can use a prescription only once a week and they tell me that's all I can do is use a retinoid once a week because I can only tolerate the prescription once a week. There are six other nights a week in which you can use a less strong version of the retinoid like I just mentioned, a retinol, a retinol, or even the retinoic acid Ester on those other nights of the week without getting any irritations.

I want you guys to be adventurous in how you're playing with retinols, and how you're viewing them as a longer-term part of your skincare routine. You don't have to use the same one every single day, and you can go low and go slow to incorporate. But once you've reached your maximum sort of tolerance level for a certain type of retinoid, you can go back and go to a lighter version that basically fills in the gaps on the other nights of the week. So, that is the golden rule numero uno. Number two: should we exfoliate when we are using a retinoid on the same night? Absolutely not. If you are a beginner, this is something that I do not recommend for all the newbies out there. People get very excited; they want to start exfoliating, they want to start using retinol, they want to start doing all the good stuff on their face. Their face blows up, they get redness, inflamed skin barriers, they freak out, they no longer

know how to approach the whole situation. So I would rather you guys see the gains slowly and get excited by the gain slowly than try to do it all at once. So exfoliate two to three times a week, and I prefer exfoliating only at night. And on the other night, to use the retinoids that you're choosing to use now. For the more advanced user, can you exfoliate while using a retinoid? Absolutely, I have been able to tolerate both for years, but it's not something that I developed overnight. So if you are incorporating a retinoid, do not exfoliate on the same night. Your skin will thank you for it. That is the beauty of skincare, you have to experiment and get to know your skin and see how your skin responds. Number three, if you are a sensitive soul, buffer. Now what do I mean by buffer? Two years ago, the moisture sandwich became a thing, which basically was serum, retinol, moisturizer. I just thought it was stupid because I don't like stupid terms that basically

or maybe I don't know. It's a marketing term, but genuinely, what does buffer mean? It means put a layer of something basic underneath, put a layer of moisturizer underneath depending on how sensitive you are, and then use the retinol last. So, if you're very sensitive, you would put - and I will show you guys - you'd use serum first, right? You would use this. You would get that on your face. You use the moisturizer on top, right? I'm demoing it for you guys. This is for the sensitive ones or the ones who are too scared. And then you get your retinol right here. I have the L'Oreal. You use this one last. But you're gonna tell me, But the retinol is a serum. Serene power using that last. I don't care because you're sensitive. Where's the camera? Because you're sensitive, I'd rather you use the serum than the moisturizer than the retinol so that the retinol is not going directly on your skin, increasing your risk of

irritation. Now, if you are a tank and you can bulldoze your way through the skin care, you take the retinol, put that one first. Okay, go to town, rub it in, and then use your serum, right? And then use your moisturizer. That is how I approach buffering versus not buffering. The other thing I would say is around the eyes, when you are buffering, this is where I use a thicker cream. I am not prone so much to milia. I get them very rarely. I'll use Vaseline. I will put the Vaseline underneath my eyes, right? And then I will go and take a dab of the retinol and put it on top. The Vaseline is a thick ointment. It's harder for things to get through it, but that is a really good way to buffer as well if you are not prone to Milia. Now, number four, when starting, and honestly, even for the more advanced users, including myself, I do not put the retinol over here. Why? Because I shed like a snake. I constantly

get irritated around my mouth. It is an area that is notorious among people and patients that they cannot tolerate vitamin A's around their mouth, and they tend to get really flaky and really red. Being in a state of chronic inflammation is the worst thing you can do for your skin, so I avoid this area, or I use a much lesser, what's the word I'm looking for, unless you're strong, a less intense retinoid, meaning I go for the like I mentioned to you guys at the very beginning, the retinol esters, or even an over-the-counter retinol. Can you buffer around your mouth? Sure, you can buffer around your mouth as well, but personally, I do not love using Vaseline around here because I get clogged. And rule number five, you need to follow it the next day with sunscreen, sunscreen, sunscreen. And I'm not a sunscreen militant kind of, but you really do have to protect your skin. What is the point of taking all of this time to invest in your skin to build a

stronger foundation to have better-looking skin. If you are not protecting it, useless. So let's quickly jump into product recommendations, starting with retinol alternatives. Now, is this a true alternative to retinol? No, but does it have some merit in the field of collagen production and stimulation? Yes. And that is because, y'all, if you are pregnant, this is what I personally used. Ole Henriksen. Indeed Labs also has Bakuchiol pads. I love this one because it is a beautiful purple hue, and it just goes on seamlessly. It does give your skin a little bit of a glow, and it's a really, really pretty product. It retails for 60 dollars. It has, like I said, Bakuchiol. It also has a little bit of glycolic acid and lactic acid, which is fine to use if you're pregnant. Um, and this is an exception to rule number two, which I told you guys was never exfoliate and use a retinoid on the same night because it is actually a

retinoid alternative now a red and nil derivative but before even talking about criminal Esters is a very light hybrid of a retinol. This is extremely for beginners or very sensitive skin people. Universal Pro retinol by glossier things I hate. I hate that they call it a pro retinol because it is misleading in a marketing term. It is actually not a pro retinol at all. It has retinol sunflower rate which is composed of sunflower fatty acids and retinol but it's not actually any form of a pure retinol at all. But it's great for beginners. It is priced at 35 dollars. It probably will not irritate your skin and at least it's something for you guys to start off with if you are nervous and if you do not know exactly where to start when it comes to retinol Esters. Everyone talks about this French one, the a313. I've been talking about it for years. The reason I think it has such a cult following is

because it gives the skin an instant gratification. The next day, that all comes down to formulation. But when you look at the actual composition of the A313, it is a light version of retinoids. It is actually a retinol, a mix of retinol esters - actually retinyl acetate, retinyl palmitate, and retinol propionate. It has a very silky and ointment-like texture when you actually see it. And I will say, I still get occasionally itchy when I use this again formulation, but my skin the next day looks extremely smooth and like an ice skating rink. I can't explain it. It's almost like it filters your skin overnight. So, that is all formulation. I don't think the retinol is working that fast, but I like the instant gratification of that product. Now, when you're talking about pure retinols, a very easy one for you guys to get at any sort of Duane Reade, CVS, Walgreens is L'oreal 0.3 for retinol. You guys can

also try SkinCeuticals. They have at 0.3, 0.5, and 1.0. But I will say that more of my patients get irritated using the Skinceuticals 0.3 versus this one, the Revitalift by L'Oreal 0.3. And I think it's because this has more of an encapsulated technology. So, if you are more in the sensitive one, I pick this. If you're ready to go a little bit stronger, I'd go for SkinCeuticals, easily accessible, easy to find for you guys. SkinCeuticals retails at 70-80 dollars, whereas the L'Oreal is around 39 to 40 dollars or so. I do hate The Dropper. I don't think I need to keep saying that, but I'm back 2023. Hey, the dropper. If you're new to my channel, hate The Dropper. The SkinCeuticals at least comes in a Squeeze Pop squeeze tube. Now, retinaldehydes, which are the step before

retinoic acid a van is a great one. They have their retinol 0.1 at 74. It is a 0.1 percent retinol cream, um, yellow tinted, and it also has their thermal spring water, which is supposedly helpful for any sort of redness that you may or may not have. And last but not least are the retinoic acid esters, the cousin of retinoic acid, the hydroxypinacolone retinoate, also known as Grand active retinoid. You have the ordinary one that a lot of people are used to seeing and we're talking about a lot during the pandemic, but more recently Caroline Hirons launched her retinoid one and two by Skin Rocks, and they are hydroxypinacolone retinoate. This retinoid one is at 0.2 percent, so it's the entry level. I have the two, and this one is mixed with retinal, so it will definitely be more irritating than the retinoid one, but they are interesting.

products to try especially if you want to jump in. And from the readings of the reviews, people are not getting that much irritation from them, so they seem to be doing great for people who are scared to take the plunge and going stronger or who are ready to go, you know, a little bit more than a retinol but don't want a prescription yet. And then last are prescriptions. So, different. Used to be a prescription up until a few years ago. It is now available over the counter. Do not use this if you are pregnant. Do not use this if you are pregnant. Do not use this if you are pregnant. It is a synthetic retinoid. It is also known as adapalene, and it is the cousin version of this is a very old tube tretinoin, which is the prescription format, and this is the one that you get from your local board-certified dermatologist. It comes at various strengths. You also can get them encapsulated. You can also get them in micro versions. It comes in different

types of formulations now. But this is the classic old school tretinoin that you can get as a prescription. And there you have it, my little nerds. Happy Saturday morning. Five golden rules. Hope you enjoyed this video. Let me know if you have any questions or comments below. Make sure you're subscribed to my channel, and I will catch you guys next week. I will be back. All right, have a great weekend, and I will see you soon. [Music]

샤린 이드리스 박사의 레티노이드 사용에 대한 조언

시린 이드리스 박사는 다양한 사업과 균형을 맞추기 위해 한 달에 세 번 토요일 오전 10시로 동영상 일정을 조정하고 있습니다.

그녀는 사용자의 경험 수준에 관계없이 레티노이드를 스킨케어 루틴에 포함시킬 때 천천히 천천히 시작하는 것이 중요하다고 강조합니다.

이드리스 박사는 가장 가벼운 레티놀 에스테르부터 가장 활성도가 높은 트레티노인까지 다양한 유형의 레티노이드와 피부 재생 및 강화 효과에 대해 설명합니다.

레티노이드의 계층 구조: 레티놀에서 트레티노인까지

레티놀은 덜 강력한 형태의 레티노산으로 초보자와 민감한 피부를 가진 분들에게 적합하며, 천천히 방출되도록 캡슐화된 형태가 가장 좋습니다.

레티날은 레티놀보다 더 안정적이고 효과적인 대안이며, 레티노산 에스테르는 처방을 고려하는 분들에게 덜 자극적인 옵션을 제공합니다.

트레티노인은 가장 효과적인 레티노이드이지만 자극을 피하기 위해 저용량으로 시작하여 서서히 사용 횟수를 늘려가며 점진적으로 사용해야 합니다.

스킨케어 루틴에서 레티노이드 사용을 위한 팁

레티노이드의 강도를 다양하게 조절하고 점차적으로 루틴에 포함시켜 내성을 키울 수 있습니다.

특히 초보자의 경우 레티노이드 사용 당일 밤에 각질 제거를 하는 것은 권장하지 않지만, 숙련된 사용자의 경우 다른 날 밤에 각질 제거를 할 수 있습니다.

피부가 민감한 경우 레티놀을 사용하기 전에 보습제를 기본으로 발라 민감도를 낮추는 완충 기법을 사용할 수 있습니다.

레티놀과 버퍼링을 효과적으로 사용하기 위한 팁

레티놀은 세럼과 모이스처라이저를 바르기 전에 바르고, 완충 작용을 할 때는 눈 주위에 두꺼운 크림을 사용해야 합니다.

자극과 염증을 예방하기 위해 레티놀을 입 주변에 바르지 않도록 하고 다음 날에는 항상 자외선 차단제를 덧발라 주세요.

바쿠치올은 특히 임산부에게 레티놀의 좋은 대안이며 콜라겐 생성 및 자극에 사용할 수 있습니다.

또한 같은 날 밤에는 각질 제거와 레티노이드 사용을 금지하는 규칙의 예외입니다.

레티노이드 대체제: 종합 가이드

진정한 프로 레티놀은 아니지만 초보자에게 적합하며 가격이 35달러인 글로시에의 유니버설 프로 레티놀과 같은 순한 레티노이드 대체품도 있습니다.

프랑스인이 선호하는 A313은 가벼운 레티노이드 성분으로 즉각적인 만족감을 주고 피부 결을 매끄럽게 해주지만 간혹 가려움증을 유발할 수 있습니다.

3 포 레티놀과 스킨슈티컬은 접근 가능한 순수 레티놀 옵션을 제공하며, 로레알은 민감한 피부에 더 적합하며 가격은 39~40달러, 스킨슈티컬은 70~80달러로 더 강력한 옵션을 원하는 사람들에게 더 적합합니다.

두 제품 모두 피부 흡수 기술이 다릅니다.

레티노이드의 다양한 종류와 용도

1은 일반적인 비처방 레티노이드이며, 하이드록시피나콜론 레티노에이트는 다양한 농도로 제공되며 자극이 덜한 것으로 알려져 있습니다.

디퍼린으로도 알려진 아다팔렌은 과거에는 레티노이드 처방약이었지만 지금은 처방전 없이 구입할 수 있으며 임신 중에는 사용해서는 안 됩니다.

이러한 레티노이드는 순한 제품으로 시작하거나 더 강력한 처방 치료가 필요한 분들을 위한 옵션을 제공합니다.
