Hi, your friendly neighbourhood chemist here, first of all I wanted to tell you, how much I enjoy your content. I really appreciate the effort you put in researching. Your explanation are always very comprehensible especially for people without chemical background. But you mentioned something that put me into know-it-all-mood. (I guess I have to do something with my education...) HA ist a so called hydrogel. Hydrogels are crosslinked 3D mesh or sponge like structures with multiple chemical functionalities. If you add 10% of HA into a watery solution, it would not turn into a sodium rock. It would turn into a gel since HA absorbs water into its pores (and pure HA does not contain sodium). It will form lumps and clumps and would not be pleasant to work with. Additionally it depends on the pH level of the solution wether HA is HA or sodium hyaluronate (SHA) because in the latter the acid group is deprotonised and carries a negative charge. That can be generated in a basic environment. Mostly that is not the case in skincare since the skin itself is slightly acidic (pH=5,5). The sodium does not even play a big role other than stabilizing the SHA in solid form, since it is only the counter ion to the negative charge. Soooo... it does not really matter if HA or SHA is added, at least from a chemical point of view. (Assuming HA and SHA have a simmilar moecular wheigt. Thank you for mentioning the size of different HA's). I suppose it is a logistical reason why SHA is added. HA crosslinks at its acid and alcohol group with itself and its salt derivative does not do that as much because, like I said, the acid group is deprotonized. Turning off the know-it-all-mood now. I hope this was a bit educational and I wish you a nice day. :)

So this is my way to maximize HA benefits to my skin: after cleansing, tone your skin with hydrating toner or any kind of toner you want. You can apply several layers of hydrating toner to soak your skin wet. Do not wait until it’s dry, apply one layer of HA serum. Next, one layer of mist spray. Wait for around 1-2 mins, use your best moisturizer to lock up everything. With this skin care routine, I can stay in air-con room all day without dehydrating my skin. Confidently 💁🏻‍♀️

@@marcelo98hv i've kinda just started the 7 skin method! haven't done it long enough to have seen the results yet, but i apply multiple layers throughout the routine and not all at once. i use one layer of toner after cleansing, then i sandwich a hefty spritz of water in between two layers of toner *before and after* HA application, so it's actually more like 5 layers throughout. fun times! maybe i'll come back to this comment section in a month and provide an update XD

I'm from Sri Lanka and I got so excited when you said Sri Lanka!! 😍😍 Ive been watching practically all your videos including the really old ones over the last 2 months. You inspired me to create a proper routine for myself. Thanks Cassandra!

I had an HA injection in my knee due to some genetic issues with my cartilage. That's when I learned more about the HA. Thank you so mich for educating! 🥰💜🌱

Love your videos. You are beautiful, witty and smart. Your metaphors are awesome and you always find a way to simplify things in a funny way. Thank you for all the effort you put in making these videos 🙏🏽

Sodium hyaluronate is in a lot of supplements, I was taking 250mg daily and developed contact dermatitis on my face, I threw out all my cosmetics thinking they were the problem but the symptoms persisted even when I stopped using everything except cetaphil cleanser. This persisted for a year and left me at my wits end trying to figure out the cause of my once beautiful skin becoming so inflamed and sensitive. Well I discovered sodium HA is pro-inflammatory! There’s many research papers on the subject and apparently it’s because it’s a low molecular weight! High molecular weight HA is actually anti-inflammatory. So please beware and learn from my mistake. After ceasing the supplements my skin instantly recovered.

Thank you for unpacking the complexities, I’ve been enveloped into the buzz, but totally confused also.

I am surprised she didn't dive deeper into molecular weight. Molecular weight (MW) is so important. In fact, too high MW will hardly penetrate deep enough to be effective, and too low will penetrate too deeply and inflame the skin. There is a sweet spot, science suggests 130 kDa. Most companies are not transparent about potency and molecular weight, so any purchase is gamble. I choose to make my own. However, I have not found a Hyaluronic Acid powder at 130 kDa, but have found others with a good molecular weight. Also, I am from Kentucky. We literally live in moisture it's so humid here. I used to hate it, now I am grateful for it!

seriously thank u sooooooo much for being out there teaching us a LOT of beneficial stuff. Thank u for existing

I’m learning so so much!! Thanks! I also discover the ordinary products and love them. You are great explaining!

Great content! Totally agree.. you must know WHAT is in the ingredients. And you MUST understand what is just being marketed! ❤️❤️❤️❤️❤️❤️❤️

Thank you for explaining and letting me/us understand in such an easy and clear way🦋💕!

If you live in a dry climate (like TORONTO in the wintertime) try using your hyaluronic acids serums and lotions as part of your nighttime routine and run a humidifier near your bed. You will have plump skin in the morning. You lips 👄 will be less chapped, too! Lol honestly use the humidifier in your room in winter ❄️ regardless of whether you use hyaluronic acid serums or not! It’s great when it’s dry out.

I am absolutely thrilled that I found you. Seems like I’m late to the game, but I can go and watch all of your past videos now!! Thank you!

Can I just say I feel oddly smart when I watch your channel.. I was in that bubble of social media influencers and didn't actually know the ingredients and what they do or what is good for my actual skin or body .. with you .. I actually know my skin and what is good for it.. GENUINE THANKS ❤..

Cheers from Italy! THANK YOU SO VERY MUCH! Why did it take me so much to find this channel??? Thank you so very much for the time, the passion and the patience you and your team put into the very high quality content of your videos!

omg i was doing research on a totally different topic to skincare and hyaluronic acid. I've only recently heard it applicable to different applications through the body. I want to say thanks again Cassandra, for telling it like it is.

I always put it on first on a very damp skin and quickly put my other actives on and then moisturizer. It works really well on my naso labial lines. Oh, and I do live in New Orleans!

I looooove this series!!!! Thanks so much! That’s very informative!

Thank you for the information! This is something I had been wondering about recently.

Excellent and informative video. I was concerned about other influencers saying that the difference between the two was that the sodium hyaluronate was "smaller and penetrates deeper into the skin". 👀 Your explanation was very thorough and accurate. Thanks.

Thanks again for great content as always 🙂 I live in the DMV where our warm weather is totally HUMID to say the least.

This video was so helpful, thank you! You should make a video about Korean skincare and their trendy ingredients like propolis and centella!

Good thing i live in a tropical country. Just ordered cos de baha HA serum. Hope this helps this summer. Thanks for a comprehensive discussion. God bless.

Thank you for helping me choose the right products

Thank you for this information, Cassandra. This is so helpful!

thank you so much for this, I was really confused about how drying hyaluronic is for me

Hi Cassandra. I am a Biologist and absolutely love the way you educate and use science. I would like that you do a video on marine hialuronics from the ordinary. And also about difference between aminoacids b5 and buffet, the website says one if for hydration and the other one for wrinkles but the formulations doesn't seem much different to me. Could you explain them please?? Thank you ❤

I use a water based moisturizer with my Hyaluronic acid so I’m happy I watched this video! ☺️

Thank you for posting this, I live in arizona so it is good to know!

You are honestly upping my Chemistry grade!! Keep it up!!:)

Thank goodness I live in mostly humid central Florida! The humidity sucks for my hair, but is beautiful for my skin.

I found your video very informative. I live in Arizona and I am also very bad at staying hydrated. I don’t drink enough water, so my skin has even less moisture. Thank you.

it makes sense I started using the hydroboost line in the summer and it was great but strangely I live in Boston Ma and winter is crazy here but the Neutrogena hydroboost lotion worked great still during winter but my face needed a little more of a extra layer

facebook recommended your contents to me and it was the best thing that site has done for me honestly. thanks for the informative contents! ❤️

You are literally becoming my new favourite channel!!!! 🌟

Excellent use of analogies in your explanation!

I have the ordinary hyaluronic acid and the hyaluronic acid and moisturing factors, I always apply the cream on damp skin and use a water spray after, and ill even put just the hyaluronic acid if I need a little extra. They are amazing if you use them right!

I didn't know ha needs moisture so for two years I was using a ha toner on dry skin in dry climate w/ grapeseed oil as my only moisturizer. My skin was crap safe to say I now apply everything on damp skin.

Well done..I love the science behind the product and skin. xoxo

As someone with slightly dry skin I've literally never had better skin than when I was living on a boat in French Polynesia even though I was barely doing anything with my skin (just suncream), and I was always convinced it was just the high humidity.

I love these videos. So interesting, relevant, and easy to understand.

I feel educated everytime i watch your videos

OMG!!!! I am using wrong this whole time, I'm so thankfull to seeing this video, cuz i was look for buying some new products with hyaluronic acid (sodium jaja) and my skin felt so dry with those I already have it start to crack, maybe because the weather is change

I live on a tropical island. It's 50% humidity in dry season(austral winter) and 80-95% in summer(austral season). That's why my skin seems to love HA!

I love all your info, and I’m watching all your videos and learning new stuff every time. My question is to know how to see if my moisturizer is water-based vs not...will it say water-based, or have water as a first ingredient? Currently I have the Tula 24/7 moisturizer that I’ve been putting on after my HA...hoping this is good! Thanks for all your knowledge!

Interesting that you brought up this topic. I saw a tweet going around that Harpers Bazaar posted an article about this finding. Somehow the article was removed. People are speculating that they didn’t want the consumers to know about HA.

thank you so much!!!!! i live in a really dry place and i didn’t t know i needed to apply moisture afterwards and after 3 days my skin became extremely dry and itchy :( it even started to fell a little sort of like peeling :( and i didn’t know what was happening :(

I just use water (spray or a wetting my hands) onto my skin after any of my humecants and massage it into the skin so that it binds to the water without stealing my body's water. Then I layer a silicone free moisturiser then I lay down a ceremide silicone moisturiser and my skin is amazing

I love your channel! Lots of information, and you explain everything so well. 💜💙💚 New subscriber 🤗

Wow very informative, this is the first time I've heard that if there is not enough humidity in the air, hyloronic acid will draw moisture from your skin.

Great video, thank you! What other products are okay to use together with hyaluronic acid?

Humidity levels in our house daily fluctuate between 68-83% (we are fighting with our landlord over this and more). However, it's paying off at the minute. I'm using Hyaluronic Acid and it isn't drying my skin out thankfully. I had also seen a video of yours stating how it could be drying if there was insufficient humidity and have been careful not to apply it alone. Great video girl (still haven't got me new bloody phone - aaaaarrrggghh! One of these days.....)

Good Morning Beautiful ☕️☀️ Your skin is glowing! I often put a very light HA under my eyes. I always wondered about “holding water 💦 IN -under there??!!? What say you?? 🦋 Kimberly from Beautiful Michigan xoxo 😘💋❌⭕️

Wow! I would've never thought the weather around me has something to say about my skin care routine too! I need to check out humidity every day along with heat now 😂!

Saludos desde Chile, eres un gran descubrimiento!! 👏👏👏 ... Greetings from Chile, you are a great discovery, very professional 👏👏👏

“Look around at the weather” me sitting in Arizona. Yeahhh imma say it’s pretty dry

You are SO AWESOME! I thought something was wrong with me when I would add HA to my routine and feel even dryer than I already am

I love love loveee the science behind skin care products! I actually used the estee lauder serum and my skin was dry as fuck .. i now know why

Hi :) Just a question: What if I spray thermal water first and then applying HA while my skin is still wet? And I would love you to make a video about thermal water in the future :)) Your content is so useful, keep up the good work and thank you!!!

Oh crap, just when I thought I knew what I was doing for my fussy obnoxious skin 🙄😔😖 Kinda happy I have to wearing a mask now

I used it right after applying aloe vera from leaf. And it dried soo much... I didn't understand why. Thank you for explaining what hyaluronic acid really is. 🙏

occlusives aftes the HA could probably help with a dry climate, sealing the moisture in

Thank you for your video I just subscribed to your channel :) Do you mind me asking if you are using a rose water toner before using HA will that also absorb water into the skin. Also what about using a facial oil like rosehip after HA?

I love this! So interesting and informative

FINALLY AN EXPLANATION!

Love your videos if you have dry skin what would you suggest thank you for your help or regular skin

Cosmedica has a 100 pure Hyaluronic Acid, but I’m not sure if it’s actually good for us. Would love your review! Thank you for watching out for us!

👍👍Thank You a lot for all the information & love u too😘😘😘

Thaaaank you ... omg I was so frustrated when my skin dried out ...

Good thing you can apply before and after HA serum is lots of toner. Toners contain water so HA will suck that into the skin nicely and hydrate it.

I’ve been using 5% lactic acid once a day in the later evening, waiting for 25 minutes for it to absorb and then applying the hyaluronic acid on top and been seeing amazing results. Not sure if I’m doing the process right but it seems to be working so far.

Hi Cassandra! I LOVE your videos! been taking your advice; it's helping me so much thx! what are your thoughts on 'hyalauronic acid powder' and adding distilled water to it, please? I think you may cringe? I add vitamin e or c to it and keep it in the fridge. how bad is this to do really? its affordable for me and seems to work well for me. I do make sure there is plenty of water spritzed on my skin when I use it. If I don't use it {HA}, my skin sometimes doesn't feel as good.

Love your videos so much!!

Hey, I have oily skin some parts and dry in others, I have little spots that just seem to be there all the time, I rarely have completely clear skin. Do you have any advice about what Ordinary products could help, or which ones I should look into first??? Huge thanks love your channel.

Would the marine one be good to use or the original one from the ordinary.

Generally speaking you can figure out the humidity by looking up the weather. Of course it is different for buildings with AC or heating, but it's a good start I think ^^ In Vienna it has 9°C and a humidity rate of 42% today :)

Any humectant can dry out your skin in the wrong conditions. Glycerin etc. too

Could you review on medik8 hydra b5 and hydra b5 intense and their differences. I would be so thankful. 👏 and thank you for your great content!

Puerto Vallarta, Mexico is very humid! I’m glad I’m using it here hahaha

Hi, Cassandra, Thanks for your informative videos. I just incorporated HA into my skincare routine. I apply it on a moist/damp face and then apply a homemade oil based moisturizer. Is this optimal or do I need a moisturizer with water in in. I drink about 3 liters of water a day and am pretty hydrated. Will using this oil moisturizer still dehydrate my skin?

A bit confusing, but very informative. I was about to purchase hyaluronic acid but decided against it.I live in the southwest. Thanks!!!!

Ok Ive been using hyaluronic acid on my skin never had a problem with it ...I have a serum and a spray and I`m in my 50s its hydrating again used properly as all skin products should be used ...People read the list on the back of the product called the inky list and use it as directed...Love the science no doubt ....

I live in Arizona and I'm 50. I use the ordinary moisturizer with HA but still feeling dehydrated, maybe I will try the serum with a different moisturizer.

I use TO Niacinamide 10% + Zinc 1% and TO Hyaluronic acid 2% + B5 every morning! Is this a good combination? 😄

I had a la roche posay hydronic acid ad at the beginning of this video LOL
