What was your winner? Should we do another bracket on a different topic? Let me know! ❤️

[@toshapace4024]

Tretinoin and yes, this was fun!

[@Kian_Nichol]

Surprisingly my winners are Glycerin and Tretinoin. Wow... i'm amazed with my result. I mean, i love Tretinoin and Glycerin so much...

[@hillary4716]

Please do a bakucinol video 😊

[@TracyD2]

Kian Fahrentia same 💯 %

[@oceanbird.]

Yes, another bracket please! It was fun :)

[@geengengena]

"I am obsessed with glycerin-there is a molecule of it here" I melted omg ❤

[@kitanakitty82]

Lol, "niaciamide probably cooks your dinner for you and give you a kiss before you go to work ". I cracked up at that. You're hilarious 😁😂.

[@youknow7856]

justice for tretinoin

[@daniella4889]

Could you do your top favourite products for the winning categories? Pleeeease 🙏🏼😬

[@makaylasampson4344]

Yes, what is your favorite product with glycerine?

[@breannaspinn3220]

I would love multiple versions of this (like moisturizers, cleansers, etc) so that ingridients who do more similar things are pitted against each other! Overall this is a fun interactive activity with a side of learning!

[@EspadasYCopas]

Yeah,more organized.

[@HZ-fg9sf]

I thought it was funny how my final two was an acid and a sunscreen ingredient. Very revealing of what I most want for my skin at this moment: exfoliation while protecting my skin from the sun and preventing more sun spots from popping up. I would name this video: "What is your current subconscious skin concern" 😄

[@thanhha4896]

When u said you’re a glycerin lover and show your at-home molecule i died 😂 Cutenesses overload

[@dsarah60]

Pls make a video about peptides

[@jdoe5873]

I love this! So well edited and your humor is a killer! Thank you for doing this.

[@miiaproductions]

I just found your channel this year, and I love your videos (both old and new). So much useful information about skincare and ingredients 🙏🏼✨

[@Looking4H8]

Interesting bracket and a great overview of ingredients in the video! Thank you, Michelle! Btw, like your humor very much :)

[@liznotslow]

Love this! Love the bracket! So unique! So smart! Do more! Yay data!

[@ozi9888]

Hyarulonic acid did wonders to my dehydrated skin 💚

[@GELA23GELA]

Omg loveeeee you and your personality!! I came here because of Hyram (another great youtuber), expecting a good reasonable channel, but you are reaaaaally awesome!!! Im a follower now!

[@ivvan21]

I love your sense of humour! This was as much entertaining as it was informative 😀👍🏼❤👌🏼

[@schmeekie1]

Wait, if we're doing science-based results for anti-aging then sunscreen should always win. The problem is that not all sunscreen ingredients were in the bracket and the ones that were might not be people's favorite.

[@LabMuffinBeautyScience]

I agree! I think if "sunscreen" was a contender it would hands down be the winner.

[@lapawa]

This was hilarious and the bracket super fun, again please!

[@may6651]

[@mariaflorenciaborioli7614]

Loved this video! Thank you so much!

[@bennik2001]

That was the funniest skincare video I've ever watched😂, I loved it. Please more of that kind of content :)

[@nataliagomez5756]

Best video ever!! Fun to play and fun to watch Michelle go through each ingredient 🤣🤣🤣 I’m laughing so hard!

[@fab9652]

Wow, wow, wow.... what a fun video/IG idea!!!! I had so much fun participating and then seeing how the end results compared to how I voted when you had it on your stories. By the way, I voted for retinol because I haven't tried tret. Same with matrixyl, haven't tried it. centella won for me, in the same way glycerin won for you; it soothed my skin at times I thought all hope was lost.

[@LabMuffinBeautyScience]

Centella is fantastic! It's interesting that it didn't take off til it was in K-beauty, even though LRP Cicaplast has been a cult product for so long!

[@Crystal-xm6zu]

I followed on IG but didn’t vote. Was fun to watch and yes please do another!

[@rosemary5005]

Wow! I love this subject! And yes I love your videos in general so... this will be a favourite 😻 Thank you 🙏 You’re my go to-expert online. I always learn something from you and have a good time. This can light up a dull day 😺 you have no idea how much you help us 🦋 Thank you 🙏 💗

[@carolannthornton1918]

Lol so funny and helpful in a colorfully mixy-matchy way!!🧸🎄

[@HWme]

I'm starting to love Michelle more and more 😂😂😂😂

[@user-gf7ud3qp7h]

Omg I love your humor!!

[@Zantetsukens]

Without going through the chart I can say Retinol ftw. I just started using it 6 months ago and it was life-changing

[@deanskibinski]

I really can't believe Retinol won over Tret in the popular vote! Like, what?! 🤣I LOVED this bracket exercise; a couple of them were super difficult for me, but I persevered! Tret forever! ❤️

[@SusanIvanova2257]

Maybe because of availability? I'm in Germany, the only way to get tret here is through a dermatologist prescription. Which has a long waitlist if you're not a urgent case. Also, other people might have more sensitive skin than you this leading them to prefer retinol. Or it might not fit their skin concerns as much, why go through the whole tret dryness dilemma if your skin is mostly good and you just want to do some prevention and hydration with your skincare. If you have next to no acne and no serious aging yet I can see why someone would choose a skincare regimen that isn't as harsh. Or someone who already has seriously dry and sensitive skin would definitely think twice about trying tret

[@alishamcg]

@@SusanIvanova2257 This answer said it perfectly!

[@nyanyamero]

@@SusanIvanova2257 You can just fly to Spain, Portugal or Italy to buy tret. It is otc in those countries. Life hack 🤔

[@DaPoofDaPoofDaPoofDa]

What a fantastic idea/ game!!

[@foreverNwonder]

This was amazing 😉 thank you 😊

[@thebeautyeconomist5700]

I loved this video❤️. I sympathize with your overthinking and systematic approach😃

[@LabMuffinBeautyScience]

[@xsaltypeach]

such a good video idea!!

[@Connie-iy9xl]

This was really interesting! I vote you do it again.

[@dadabml8911]

Awwww... Missed this bracket.. Pls do another 🙏🙏🙏

[@tojihive]

this video just helped me understand how brackets work

[@MsFuzzyBuddy]

It was a tough pick! Fun to see the results though :D

[@alexandra109]

New subscriber. Came over from Hyram. Loved this! For me Tretinoin is much more effective than Retinol. The amount of difference in my skintone and reduction in wrinkles in the year I’ve been using it has me believing in it over everything else. I’m 42 and I think I look better now than I did when I was 35.

[@reginamalina1273]

Tretinoin is much more potent! Dr Shereen Idris explains this in her Retinoids explained video :)

[@dEliadaFish]

that was so cool!!

[@laurenlewis2949]

This was so hard but a lot of fun! Would you do another updated bracket sometime?

[@hanagreg]

Hey Michelle, do you have any opinion on Tamanu oil?

[@girliegirl57]

For an azelaic acid product with a nice texture, I've been using Paula's Choice 10% Azelaic Acid Booster - I LOVE it, look forward to putting it on every day! The lightweight, sink-into-your-skin texture was the first thing I noticed about it. I have just ever so slightly oily skin, this felt moisturizing AND not at all greasy - I think all skin types would love it. Definitely give it a try!

[@HarryLovesRuth]

Somehow your bracket worked out to the way that I would prioritize my various products if I had to rank them if I had to give them up. We are very smart.

[@LabMuffinBeautyScience]

YES WE BOTH HAVE THE ONLY CORRECT OPINION, OBVIOUSLY. HIGH FIVE ✋

[@dayanna1386]

That was incredible! would u share with us how to prepare a cream with retinol for the body?

[@Sebmar24]

Hi Michelle, try the azelic acid from geek & gorgeous. It's an absolutely pleasant serum to use. Love watching your skin-nerding videos 😍

[@beer_bad]

I just luve your sense of humour! I WANT NIACINAMIDE TO COOK ME DINNER! NOW!! 🤣 Btw, tretinoin & niacinamide aaaaall the way. (But tretinoin was the winner.)

[@qingliu1784]

Enjoy this excercise , fun and testing my knowledge after viewing so many skincare videos since tow months , my result is approaching to yours , happy .

[@HWme]

8:09 "You can light fires with Petrolatum 😁🔥" 8:20 👀👀👀 l i f e h a c k

[@MaxineV]

I found it difficult because although my skincare routine is minimalist. Many ingredients came to my skin rescue with the acne when I was a teen to my now rosacea... It was indeed difficult to pick the ingredients. I would be very curious to find out what other people include in their daily skincare regiment; that could be fun info.

[@chelseac198]

Adore this video!

[@roushanwar5139]

You are awesome !!!! This was sooo cool... even better than school... please make more such informative videos... thank you so much ... u are amazing

[@LabMuffinBeautyScience]

Thank you so much! ❤️

[@imperialtower]

9:41 whT the fuck your channel is actually so gold i cant believe i never started watching your videos before

[@franciscolodix1214]

Love your videos.

[@HelloThereIAmAlice]

Love seeing so much of your personality! I think this is the video where it’s showing the much so far. There was a lot of ingredients I haven’t even heard of, I want to research them and would love it if you made a video about the more uncommon ingredients. I’m Swedish so maybe that’s why, for example I’ve never even heard of Tretinoin (probably only exists when prescribed here)

[@TheFierina]

Tretinoin = retinoid acid 😊😊

[@mary2270515]

Tretinoin = Retin A

[@sorational]

please make a table with all ingredients, how they are backed up with researches, how they strong/important to your skin. It would be great.

[@JPMJPM]

How creative and fun!

[@jenniferlee9029]

Hi just found your chanel today and i'm obsessed!!! I'm statring Tretinoin soon and i was wondering how many nights a week i should use it to be effective. I don't want to use it everday even in the long run. Thanks!!!😙

[@yz4043]

Very interesting!

[@helen37x]

Loved your petrolatum vs bp rant 😂

[@thebeautyeconomist5700]

And I’m looking forward to the video on Azelaic acid products. I have mild rosacea and I tried TO and Skinoren Rosacea and hated using them because they were both very matt. My skin is on drier side.

[@LabMuffinBeautyScience]

I don't know if it's possible to make an azelaic acid product that isn't pretty matte... have you tried mixing it with an oil or other moisturiser?

[@thebeautyeconomist5700]

Lab Muffin Beauty Science is it ok to mix it? I’m always worried to make the formula less effective if I mix it with something?

[@LabMuffinBeautyScience]

@@thebeautyeconomist5700 It could make it a bit less effective, but if the alternative is not using it or using significantly less, it's worth a try!

[@michellegoldsmith]

Hey Michelle, what about Bakuchiol I would love to hear what you have to say about that.

[@azharel]

Mine is Tretinoin.. from normally having adult acne for years, when I am starting using it, for the last 6 months, I only had 2 small acnes. Fingers crossed it will be my long-term use!

[@fabiane694]

woww! cool, do thit with hair ingredients as well, pleaseeee

[@sarahserenity3872]

I just found you thru your micellar water vid then started watching this one. Whoa, i didn't realize how much of a noob i am! Do you have an ingredient vid that's for beginners?

[@beckyc.5743]

Great video, Michelle. My final pick was tretinoin. Of course, that means I probably won’t be using effective sunscreen so I will become nocturnal.

[@angiea1243]

Hi! You said in a video, I'm not sure which but I keep looking for it and can't find it😔 that you can use glycerin on moist skin and don't need a moisturizer on top correct?

[@DanicaSundin]

✨UREA! ✨

[@rashasarandah1695]

How do you feel about propolis and what product with propolis would you recommend for acne prone skin?

[@susanneflora3133]

I would love a comparison review on different niacinamide products! 😃

[@briesullivan883]

Can you do a video on how to get the most benefits and product absorption out of our sheet masks?

[@NickLS7]

When you first posted about this on Instagram, I thought for sure your final bracket would be Tretinoin vs. Vitamin C! I severely underestimated your dedication to Glycerin though lol. Also, I was so disappointed that the popular vote picked Retinol over Tretinoin, ugh.

[@mitchmartillan9390]

Hi Michelle this has been kinda difficult decision to make with but I really had fun hahhaha thank you for this. anyway I wanted to ask you if it is safe to use together 5% Niacinamide and 10% Vit C in the morning? Thank you

[@AllTheArtsy]

Retinoic acid and L-ascorbic acid. Those are the answers. 😝

[@LabMuffinBeautyScience]

Very fine choices! 👍

[@classicallydiana8255]

I honestly can’t even remember what I ended up with 😂. It has to be either Glycolic or Centella...two ingredients that I’ve actually seen results from. Although, it could’ve also been Retinol or Vit C 🤔. This was fun!

[@seanvalentinus]

Michelle is the only cosmetic KZbinr who also teaches me how to burn things.

[@margolane8529]

Can you do a video on ceramides?

[@subhkhan]

Hi Michelle-quick Q...I wanted to formulate a brightening cream for pigmented skin which is packed full of tyrosinase inhibitors...I really want to get 9-octadecenedioic acid in there affordably but finding it difficult. It's molecular size seems to be better & more potent than azelaic acid....do you have any idea how I can get my hands on it as an ingredient or is there some kind of workaround?

[@claudialaroja1225]

“Light it and then it burns really well, so it can set the rest of your fire ...on fire. Life hack” 🔥

[@LiaLia-hx1ii]

Hi Michelle, how about advising us on Avocado, Grapeseed, Jojoba, Evening Primrose, Almond, Safflower Oils for skincare? I applied all these oils on my skin but find them hard to completely aborbed well into my skin even after 5 minutes.

[@i.m.hidden2788]

Tretinoin & Matrixyl are my top two. Can't pick between them. lol. When I was younger, My top 2 would probably have been niacinamide & lactic acid, back before i had my rosacea under control. Fun activity & great video! Thank you!!!

[@talesandstars9623]

Can I use 1%glycolic acid on a daily basis.. Will it damage my skin on long run??

[@paulawilkinson6341]

Oh gosh I just love watching you Michelle . Naimacide may cook ur dinner and give u a kiss🤣🤣not only are ur videos educational ur so funny 😂 xxx

[@robert5117]

Is collagen good for the skin. I know my mom takes it everyday as a supplement, but can you apply collagen to skin?

[@andreaparker2069]

Totally confused by this. I looked at the blank bracket to try to figure it out. I wanted to play too but I am just too dim.

[@vicg2938]

i had an unopened package of glycerin in the back of my closet and i just opened it up. I have never used it and now I am 100% sold on glycerin.

[@hellowchanYT]

Come down to Glycolic vs. Vitamin C. I refused to pick.

[@jessicas4295]

Have you done an updated version of this yet?

[@theyogainn]

My final showdown would have been zinc oxide vs centella. Sunscreen is the most important, so you can’t not have a sunscreen filter in the final imo. Also, chemical sunscreens irritate my eyes. Zinc oxide is a life saver for me (when I can find it in a sunscreen that doesn’t have a white cast). And centella is just amazing. I feel like it’s soothing, helps speed up wound healing (I put it on any little cuts I get), calms down my redness, and gives me a more even skin tone. I have more dry/sensitive skin tho so I’m biased 😂

[@kamleshverma123]

I use tretinoin, niacinamide, vit c, and glycerine. And i love it

[@Mystictarotbyshobhna]

Amazing 🤩

[@snkfrk10]

Hahaha. This was so good. Loved it. I got niacinamide.

[@weeesah]

can i mix glycerin with lactic acid?

[@CaitKant]

Thanks

[@Lorvina1]

I'm curious how urea would have fared in this battle. Maybe you'll do this kind of thing again.

[@fstkpfls]

My winner was salicylic acid because it had the most dramatic effect on my oily skin and I just couldn't without it. Haven't tried retinol or tretinoin though
