Which Retinoid Should You Use? Types and Percentages | Retinol, Tretinoin, Retinaldehyde, Tazarotene

Could you please comment on the European Union’s decision to limit over-the-counter retinols concentration to 0.3% by 2024? I find this crazy ,if this efficient enough?

Can i use retinoids over years ?
Like can i use it always... more than 6 months in a row every 2days a week?
I have hyperpigmentation and acne also...
Please answer ❤

Thank you for your detailed and informative videos. Do you recommend a retinoid for around the eyes, like the Medik8 Crystal Retinal Ceramide Eye? And then would you apply an eye moisturizer on top of that?

Does phone light and tv (artificial lights) affect the tretinoin?

I am 78 years old and I have been using Tretinoin 0.1% every night since 40 yrs old. I am noticing that I need some hyaluronic acid for some depression in my cheeks. Is there anything I can use from the Ordinary line for that? I have sensitive skin and it has taken a long time to work up to 0.1% every night. I started it because of acne. Now what can I do in the morning? I also use a moisturizer at night after applying 0.1%. Thank you.

PLEASE DO A TAZAORC / ARAZLO dedicated video.

Is it at all beneficial to alternate using tretinoin and a retinol, say when my skin is irriated from tretinoin? Thank you. Love your videos.

Is there a brand of prescribed tretinoin that you recommend?

Hii i use cerave resurfacing retinol serum
I want to know if i can move to trentinoin 0.05% for acne purposes

Hi Dr 😊 Are you able to tell me how many days / weeks I can actually go without using tretinoin at all before I begin losing the tolerance I am building? How quickly does your skin forget?

What about adapalene?

Which type of tretinoin to use? Microsphere or cream?

Hello Dr Liu. I went from using a prescription tretinoid 0.025 from my derma to trying one with additional ingredients like the one from The Agency this prescription included Tretinoid 0.05, Nicinamide, Azaleic Acid I did get a reaction contact dermatitis and discontinued use. My question is should I stay with my original tret of 0.025 or have my derma go up 0.5 ? My goal is more anti aging.

Will changing from 0.1% retinal to 0.02% retinal still deliver anti-ageing benefits to the face long term despite the latter being of low concentration? The reason for the switch is that the 0.1% retinal formulation has fragrance in it. Thanks

Hi! I am new to your channel. I am 52 years old and have pretty much ignored skin care till a month ago. I am Filipino, have history of bad acne till maybe in my 30s, never really wore sunscreen. I live in Central Florida so its humid here. My main concern is pigmentation maybe due to acne scars and I also have sun spots plus wrinkles on my forehead thats more pronounced now. I also have dark circles and baggies under my eyes. So I am changing my routine right now slowly as I do my research watching videos online. So what I am thinking for am routine is Cerave SA cleanser, timess Vit C serum, Vichy mineral 89, Australian gold sunscreen or le roche posay double repair with spf. I have tried the cleanser and Vit C and I can tolerate it pretty well. My night time is the one I am still putting together....I have le roche posay cleanser and currently using timeless coq10 serum, timeless eye cream and LRP double repair moisturiser. I have ordered and want to include the following.... naturium glycolic acid which I saw you recommend on one of your videos, and I also ordered adapalene., versed eye balm, etc. My question is how do I introduce glycolic acid and adaoalene into my routine that won't freak out my skin. Also, will adaoalene work for antiaging or should I just look for a retinaldehyde? I remember as a teenager using tretinoin but financially can't afford dermstologist right now. I have also experienced dermatitis 10 years ago and I think I was mixing products I had no idea did and it just freaked out my skin. Thank you so much for your content and I have loved watching your videos :)

This is helpful! What about differin? Does it have anti-aging effects?

hi Doc! is it okay to do the skincare after 3 to 4hrs of double cleanse?

if you're a beginner to retinols or rerinoids entirely, what should you start with? can you give me cheap products or percentage advice?

As a PA I love that you stuck to data and statistically significant results. Thank you for also being straight forward and to the point, great video.

Can l mix tretinoin with tazaroten?

0.025 is effective for me but in the third week, I experienced headache, pain, and heart flutters. I'm not sure if I'd do better with other brands.

I have lots of big hypertrophic acne scars. And i have a rough skin type. So which percentage of tretinion should i use? Please help me and suggest me 🙏🙏🙏 i m tired with my big hypertrophical scars 😭

Using anything less than prescription grade vitamin a topically is pointless really, people are wasting money on something subpar, go with something that is proven to actually work that actually deliver results instead of toying around.

For acne, is tretinoin or tazarotene better? I have many little bumps and occasional acne

Your skin is beautiful Dr. Jenny!

My family and I have been using them for 40 years yet now all these millennials are just finding out about it and now all these Dermatologist are trying to bank off it 🤦🏽😂

Hey Dr. Jenny, I ordered various products according to your recommendations and I’m a little confused on exactly which products will suit my skin type and specifically which products are safe for me to use. I need a step by step skincare routine. Therefore, just to give you a summary. I’m 19 years old that is dealing with hyperpigmentation due to post acne marks, I get white heads from time to time, and acne that’s always white and painful and ready to be popped😂, it keeps on growing on my chin and the sides of my face and a little on my forehead. I was thinking about buying adapalene by la roche posay adapalene 0.1%. I also ordered your recommended Cera Ve benzoyl peroxide cleansing foaming cleanser and now I’m ready to use adapalene. Which retnoid would you say is best for my skin and age. Is there anything else you would recommend?

super interesting video, thank you for outlining studies and talking specifically about aging vs acne. this was exactly what i was just looking for :)

Thank u for this thorough explaination
I am 35 years and have wide porse and just started to have lately saggy and very dehydrated skin, but i am so confused what type of retinol family to use
I will be so grateful if u can recommend a type and product for me

How about low retinol concentration? 0.1% will help with fine line? If Yes how long will take to see some improvement

Please I am trying to age slowly, what percentage is the best to use please?

You have stated that if you tolerate it daily and want to maintain results, you can reduce to 3x per week. What if you never take it up to daily use to begin with, is 2-3x per week still effective/beneficial? I ask because I also use AHA products and like to alternate, but I also want to leave a night or two with no actives. My goal is anti-aging and I am using 0.05% tretinoin gel. Thank you!

How do people who dont use the “sandwich method” apply their tret? I apply moisturizer first, let it dry, then tret on top

Just wondering, does putting moisturizer after tretinoin lowers the efficacy of tret? How long does it takes for tretinoin to absorb into the skin? Of course, it depends on how sensitive your skin is/ how it handles and whether it requires moisturizer.

But I've been curious on how to amplify the effectiveness of tret and whether is true by just applying tret and nothing else after (like serums/moisturizers) can really reap the benefits of tretinoin.

Amazing video! Thank you. Question - I have been using tazarotene .1% for over five years now, initially for acne but now I'm mor concerned about photo aging. Is there a possibility that skin can develop a tolerance to the retin-a and thus it becomes less effective over time? Or no? I'm just nervous since I'm already at the max strength there's no way to go high as I get older

What about not using every night when using tazarotene for acne? Is it sufficient to use it maybe 5 nights a week to maintain benefits for acne prevention?

Dr what do you think abt. Altreno lotion...I been using since September...little irritation/redness in the beginning...I see improvement and it's very moisturizing...but I don't hear any derms talking abt this one..thank you

I use 0.1 tretenoid (Curology) for 3 yrs
But I started using RetinA in the 70's when it first came out. I am 70 now and Still have breakouts...but very few lines!!

Hi dr. Liu I think I build up my tolerance on my adapalene I'm almost 4th month on it and planning to use nightly? is that will going to weakened my skin barrier? or I will get the best results?

I’ve got prescription for Retin A Micro gel 0.04%. Does it have same efficacy as Tretinoin?

I am on tretinoin 0.05 and using the retinoid sandwich method due to damaging my moisture barrier with onexton and tretinoin 0.1. Winter came and it was so bad so I quit onexton and use a bpo wash plus tretinoin 0.05 using the sandwich method. I love the sandwich method and plan on continuing it long term. In summer I am considering go back to tretinoin 0.1 since I. Use it for acne purposes to keep the hormonal stuff at bay when my cycle comes around. Is it bad to continue the sandwich method long term? I am only considering the bump to 0.1 if I continue the sandwich method since I don’t think I can tolerate it on my bare skin due to retinoid dermatitis in the past. Thoughts on the bump and long term use of sandwich method? I loveee your channel is has helped me so much. Derm just told me they want me on 0.1 and no guidance or tips how to get there

Thank you for this video! In future videos I would try to avoid so so many cuts. It makes the speech weird, and I get nausea watching every sentence being cut off.
I love your routines videos that don't have so many jump cuts. Thank you.

What do you think of Retinyl Retinoate, especially the Medik8 products containing it?

This was extremely interesting. Thank you for not simply regurgitating info we have heard before. You definitely have a unique perspective.

Can a glycolic 25% moisturizer be used on top of adapalene? If not, would everyother night be ok?

Thank you for the clearest explanation of retinoids I've seen. I also appreciate the caveat regarding damaged and aged skin not benefiting as much from a retinoid. That would actually be me. I've been using the Avene .1 retinaldehyde but it's pricey. Would love to see a video addressing these types of skin concerns for those of us over 65.

Thanks for the data! It was super interesting to know that 0.1 and 0.05 didn' t show up a drastic difference on a biopsy🔬 🧛🏻‍♀️🖤

Best video I’ve seen about retinol. I’m on 0.01% trentinoin cream for about 10 months and my skin looks the same. I use it every other day. I’ve had no irritation when starting. Do you think it’s worth going to 0.025%? My goal is to prevent aging/wrinkles. Thanks 😊
