Is tretinoin better than adapalene? Ultimate Guide to Drug Retinoids

Drug retinoids like tretinoin and adapalene are some of the most powerful skincare ingredients. But what's the difference between them, and which one works best for acne, anti-aging, or pigment? And what about the different formulations? I'm breaking it down in this video, and busting a bunch of retinoid myths too!

That’s awesome. I’ve met quite a few cosmetic retail workers that were telling me things I knew to be untrue. Glad you are educating yourself!

[@DallasNatureLover]

This is awesome! Too much skincare “information” being shared in retail stores is wrong because the actual science behind skincare has been limited to cosmetic chemists and dermatologists, and sometimes the dermatologists don’t get it right. Lab Muffin’s science and product nformation information has been very valuable to me and it’s great to see it getting shared.

This is kind of bizarre, I was part of the final clinical trial for retinol for acne 40 years ago. It rocked I would like to say. It basically peeled my skin and all the craters and scars didn;t reform. And the acne kind of magically didn't come back. Now I use retinol to"fight the signs of aging" . Good old retinol!

[@SamFerro]

If I was infinitely rich I’d pay you anything to teach chem/orgo at universities. You have the best analogies to help make complex concepts tangible (i.e. using the boba reference for the tret/bpo formula to explain why it works), and to echo everyones sentiment, you are an exceptional teacher/communicator.

I never realised how irritating tretinoin can be for most people - while my skin will freak the hell out at the slightest change of humidity, it's tolerated tretinoin incredibly well, never reacted poorly. And it has absolutely been a game changer! I'd been suffering from acne right from puberty, and it just never went away no matter what my routine. Tretinoin has been the only thing to clear up my skin long term

It's so amazing to finally understand how these acne treatments work! I suffered with acne throughout my entire adolescence and early adulthood, so I tried everything you can imagine, except for tretinoin - where I live doctors normally use it as a last resort thanks to the amount of side effects. Oddly enough not even adapalene worked in my case (I used Epiduo), so I decided to see another dermatologist to get a second opinion and as soon as she saw my acne she prescribed me antibiotics (Tetracycline) and topic azelaic acid. I not only finally got rid of my acne, but my blemishes were pretty much gone in a matter of a couple of weeks as well, which was great since I am prone to hyperpigmentation (I have tan skin). After that, the few times I got a pimple benzoyl peroxide alone was enough to deal with it. It's crazy and fascinating how our bodies respond differently to substances. I spent loads of money on expensive retinoids throughout the years, but the antibiotics which cost me under 10 bucks per box were the only thing to actually solve my problem.

[@LabMuffinBeautyScience]

That's so interesting! From speaking to derms who see a lot of acne like Dr Mara and Dr Anjali Mahto (I collaborated with her for my food and acne video), it's pretty common to have to try a few first-line treatments to tackle acne, and sometimes they'll work for a bit then fail and patients have to switch. Glad you found something that works so well for you!

[@noneofurbusiness5223]

@kayc . . . Curious. Did u take Tetracycline topically or orally?

[@gluckwunschwinston5618]

Where I live antibiotics are stndrd for acne. And they work very well for a lot of people. Only downside is that in most cases the acne comes back pretty much immediately when you stop taking them. Usually you can't take them for more than 3 months.

[@genshinF2Play]

I took antibiotics too but it's not a long term solution since you have to stop it at some point. Enjoy it while it lasts. Because it will comeback soon.

[@Alex-dj9qj]

I love adapalene, I use it for acne and overall skin texture and smoothness and it’s been amazing. Tretinoin was very irritating for me and caused more issues long term with post inflammatory erythema and random big breakouts. Now my skin is finally happy and glowy phew. Interesting how much of a difference changing the retinoids u use can make

[@arguchik]

I recently started using adapalene, and I'm also having good results with it. I'm older, so my problem isn't so much acne anymore, except that I get occasional pimples and a lot of closed comedones that are quite difficult to get rid of. The adapalene is taking care of them and my skin looks a lot smoother and healthier now.

Hi Michelle, Thank you for recently mentioning the L'Oreal Bond Repair range... which I have now switched to. I purchased the shampoo, conditioner and the serum. I was previously using a hydrating shampoo and conditioner, which made my all-over blonded hair clean, soft & silky...but it also made it lank and "stringy" not too long afterwards. Because my hair is naturally oily, I was just thinking that this happened to my hair whenever I had more than 1mm of regrowth... when it was the shampoo & conditioner all along! So now I don't have to squirm every time I look at photos when I am wearing my (past shoulder length) hair down. In fact, on the weekend I met up with a cousin (from Europe) that I had not seen in 40 years and wanted to look my best. Thanks to you, Mo (moskinlab) and Dr Dray, I actually went out socially for the first time in a million years without foundation or powder and just washed and dried my hair with hardly any styling. I felt more relaxed and looked better & younger than I usually do...both in real life and in photos. My boyfriend said that he has never seen me look more beautiful. I've always been a glam full-face make-up girl, but now realise that I don't have to cover the pimples or freckles/pigmentation that I used to have. It's OK for my skin to look like skin. I still wore eye makeup; but no eyeshadow (except a subtle champagne liquid glitter on my lids) and petal pink lips. I admit I did have a trial run the previous day, just going to Bunnings, Chemist Warehouse & Aldi! 👱🏻‍♀️❤️

[@helenap3822]

I eagerly await the video on cosmetic retinoids! I'm not using them on my face any time soon (too ADHD to use sunscreen consistently), but I'm interested in potentially using them on my body.

[@Anni_ka]

Ohhh, this is right on time! My derm has been prescribing me Trifarotene, and it's been...a process. Sure there's technically no irritation, but the peeling is insane and even one year in not totally gone. I can also only use a handful of other skin care products because so much stuff makes my skin burn terribly (just as a sensation though, not actually burning happening). Before I've had an adapalene and benzoyl peroxide combo, which I hope to get back to, because I had almost zero issues with that 😅 Either way, that's the end of my rant, thank you for the video! The way you presented the advantages of the different retinoids pointing at scientific evidence/support is super helpful!

[@itsgonnabeanaurfromme]

Trifarotene is one of the new ones drug companies have been pushing, particularly that one that developed epiduo. It's far too expensive in my opinion. And they have been pushing it for the body.

[@nandiniinfinity]

Michelle, thank you for your wonderful work over the years. If you take video ideas from readers/ viewers, please consider these: - The current state of innovation in the hair colour market. My particular interest is in why there are so few deposit only options, especially formulas based on dye precursors in henna and indigo; after all many people colour their hair for grey coverage and not fun/ fashion and these types of formulas could theoretically achieve that with limited colour options. - How companies (especially big ones) develop the fragrances they use in products, both the chemistry side of things and the sensorial side (how do they test if people like a new fragrance etc.) - As end users, what rules of thumb can stand us in good stead when choosing products and brands for maximum scientific soundness in formulation? I feel sometimes one can't just rely on the brands being big and international. Dove, for example, has stupidly gone "paraben-free" and many of their hair products in my country now contain MI. Thank you again.

This is fascinating. Thank you! I have super oily, sensitive and acne prone skin with melasma. I began my retinoid journey at the age of 42 with many over-the-counter gentle retinoids. My skin was always irritated for at least a year. So I tried differin, and that was less irritating than retinol. It also worked better for my acne. I used it for 2 years but I still had a small amount of acne, although it did help a little bit with fine lines. Finally got Tretinoin gel .025 percent. Hallelujah! Finally all my acne is gone. So is pigment! And my fine lines. In fact I look younger than I did 5 years ago. I'm blown away. I didn't believe the hype and I didn't think my sensitive skin could handle tret. But I do use the moisturizer sandwich method with niacinamide and centella toner first. Now my skin can't handle ascorbic acid any longer but I do use THD instead and I like it.

My first introduction to retinoids was tazarotene and it was awful, I stopped using it after 3 months and stopped using anything for my cystic acne. A year later I saw another derm who prescribed Epi-duo and that was a game changer. Three years later I am on tretinoin .05% and my skin is clear and healthy with minimal breakouts. Why a derm would start with that I do not know but your video is anecdotally accurate.

@AC-dz9yq How about Adapalene. 3% Rx before going to Tret

[@gtan307]

Great video and very great detailed breakdown of everything retinoid. I personally found that the best retinoid is the maximum threshold your own skin can tolerate. For eg, if your skin can only tolerate adapalene 0.1 (given that you have experimented with different retinoid strengths), then that’s the best one for you at the given moment. If the higher ones irritate you, ofc you need to take a break because inflammation is the sure fire way for quicker aging. If the lower strength still doesn’t give you results after using it for a good while (ie. still have bumps or still dull, etc), then gradually increase to one level higher. That’s just my 2 cents.

FINALLY, you have no idea how long i have waited for a video like this. When I originally watched your first videos on retinoids, I became so curious about how tretinoin works because its kinda vague just saying it goes on your skin and voila. I am still curious how the retinoic acid receptor being bound actually changes biological processes but from what I have researched, there just isn't much knowledge on it. Still this video really helped explain the papers I read on these forms of retinoids in simpler terms!

[@LabMuffinBeautyScience]

I really don't enjoy biochem so I generally blank out everything between receptor binding and biomarker/macroscopic impacts, but a very rough outline is: the RAR joins up with another type of receptor (RXR) and they mess around with the DNA of the cell, which then changes how the cell works. Maybe try asking Dr Dray? I believe her PhD was on molecular biology, which is this kind of thing...

So was thinking about the new formulas as I've heard the claims of them being less irritating but now thx to you I will just continue my routine as it is. Tret is widely available and affordable where I am whereas the newer formulas not easy to find and double or triple the price. So tret it is until You make a video telling me there are evidence that says I would benefit from another formula. On a side note, adapalene irritated my skin more than tret did. And for a long time I thought I wouldn't be able to handle tret but I'm doing just fine as long that I'm hydrating and looking after my skin barrier!

My favorite retinoid, palovarotene, isn't here-probably because it isn't even a skin drug. It's a new treatment for FOP, the rare disease that turns people's soft tissue into bone, but its efficacy is extremely controversial. Still pretty cool any time a rare disease gets a new drug though. It's also a very selective RAR-gamma agonist, so it probably does work on skin, and some of its side effects are the same as the side effects from topical retinoids. I love the explanations of what the different moieties are doing in the pharmacology of each retinoid, as someone who reads SAR papers for fun lol.

Re: Tretionoin studies... "A lot of people in these studies are teenage boys and men" ... I wonder if this also accounts for this disconnect with doctors and female patients.

Ist auch eine Pumpflasche, was für mich extrem wichtig ist, weil ich mega pendatisch ängstlich bin und schlecht im Schätzen wie viel Creme ich jetzt genommen habe. Und da ist halt alles drin Cleanser, Feuchtigkeitsdings und die Formel mit Tretinoin für den Abend und wenn du magst noch Sonnencreme dazu. Wobei ich nur die Sonnencreme da jetzt nicht mehr dazukaufe, nach einmal probieren. Da nehme ich lieber was leicht einziehendes wie Beauty of joseon Relief sun rice+probiotics für die Tage, wenn ich kein Sport mache oder ins Wasser geh. (aber Achtung net kaufen bei dunkler Haut weil einer der chemischen Filter weißelt+net kaufen wenn Augen schnell gereizt sind, weil manche Leute reizt es vom Geruch)Mir ist halt wichtig das schnell einzieht und nicht glänzt Ich finds prima, weil ich außer Sonnencreme und Benton Pha peeling nix kaufe mehr. Und weil ich immer bei Dermatologen fragen kann und da meine Bilder von der Haut regelmäßig einsenden. Die nehmen sich Zeit und antworten relativ schnell. Halt an Werktagen natürlich

Hi! You mentioned that adapalene does not work on post-acne marks and scars as well as tretinoin and tizarotene, but does it still work on them despite not being that good? I'm thinking of buying adapalene, and i really want to get rid of my deep acne scars. Love the video!

[@Hara877]

Do you mean like pitted scars? I can’t speak to that but I can say that I had very severe post inflammatory hyperpigmentation and discoloration as well as acne and adapalene helped tremendously and within 6 months my skin looked even and perfect.

Please make a video about moisturizer

I have only used the over the counter stuff and then Differin cream, and now am using the Geek and Gorgeous A Game 10. After this I am thinking of using Dermatica. I found the cream form of differin good, i have dry skin so the cream was much better for my skin and it never irritated my skin

[@noneofurbusiness5223]

@lavayuki Didn't know Differen came in a cream. Cool

[@livics610]

I have some topics of interest, if you think they are helpful to expend on: - are Estradiol/ Estrogen creams safe to use on the skin? What if you take the pill? Is there an age related recommendation? Frequency? Etc. - what do you think of Phenol peel? Is it the only way to penetrate deep into the skin to boost Collagen, or what other ways are there? Etc. - what do you think about Ectoin? Combination of Ectoin with other ingredients? What products would you recommend? Etc.

I live in a country where adapalene is prescription only as an acne treatment and my GP has refused to prescribe it for me. I have to buy OTC when travelling or ask family abroad to do it for me. Thanks for the clear info on the different types.

Hello, love your video's as always. Could you explain about copper peptide. I saw some people say in comments in other video's (not yours) that it could grow hair on the face but i did not find any evidence. Also with age, women are more likely to produce hair on the face, so i don't think there is even a link or these people did read that on things like blogs etc. I guess more people concerned about aging will use these products because retinol can be irritating for some, so they make these links that aren't even connected

[@selina2053]

I love that top! do you have the pattern?

Can u do a video for sunscreen and products for black women with hyperpigmentation?

[@twinklepahwa4435]

Can you make a video on extreme cases of keratosis pilaris please

[@lynnhom6915]

Thank you. PLEASE tell me if I can use tazarotene for life. So far been using for 15 years.

[@lucassavioli1031]

I used adapalene and tretinoin. For me both were equal in irritation, mild in my case. Tazarotene discontinuation was approved by ANVISA (i dont know why) thus not avaliable for me to use. I still use tretinoin (mostly because is cheaper) and worked great for my acne
