Hyaluronic acid and its function in the skin.
Hyaluronic acid is a ground substance. Combined with collagen and elastin it forms the mainstay of the dermis. HA is produced by cells called fibroblast. Hyaluronic acid has come a long way over the past few decades with new formulations, both delivered as a cream topically to the epidermis as well as fillers delivered into the dermis. New methods of making HA has resulted in better, longer lasting HA molecules.
How is hyaluronic acid made?
Hyaluronic acid is manufactured using sterile techniques. In the past, hyaluronic acid was manufactured using rooster combs. Newer forms of hyaluronic acid for creams contain different-sized particles known as polymolecular HAs. These variable size molecules enable better penetration into the epidermis. As yet, there are no forms of hyaluronic acid applied topically that can reach the dermis.
What HAs are best to use?
Most manufacturers now provide a poly molecular weight hyaluronic acid creams. Companies such the Ordinary makes a cost-effective hyaluronic acid. In my opinion due to the fact that hyaluronic acid is degraded within 24 to 36 hours, spend your money on hyaluronic acid for dermal fillers rather than creams. Dermal fillers act in the deeper parts of the skin using cross-linked hyaluronic acid. Dermal fillers will last anywhere between 6 to 24 months depending on the brand and cross-linking. Hyaluronic acid applied on the skin will degrade within a day or two.
How can I incorporate hyaluronic acid into my skin care routine?
If you are living in a humid environment, hyaluronic acid can be used on skin without preparation. This is because hyaluronic acid acts as a humectant drawing moisture in to the skin. If you live in a low-humidity environment, hyaluronic acid should be applied after a bath or shower and occluded with your moisturiser of choice. This is to decrease dehydration from your skin due to large-particle HA creams which may not go into the lower aspects of your epidermis.
Hyaluronic acid in dermal fillers.
There are many types of dermal fillers consisting of hyaluronic acid, I do believe that working with many different brands and subtypes is important because it gives a good selection of material for your dermatologist or plastic surgeon. Hyaluronic acids which are cross-linked and dense can be used as a foundation; however, more fluid hyaluronic acid fillers can be used to improve areas such as under the eyes.
What Hyaluronic Acid creams do I recommend?
Every skin care company will have a variation of their formulation of HA in either a serum or cream. The Ordinary produces cheap, cost effective HAs. If you have sensitive skin, opt for a cream over a serum. If you live in a low humidity environment make sure you moisturise after applying HA creams/serums.
Can Hyaluronic Acid be mixed with other skin care?
Absolutely. HA can increase penetration of actives into the deeper epidermis. Because pure HA is part of your natural component of your dermis, this molecule is banal meaning it does not present itself as an antigen. Allergy to pure HA is almost unheard of, if you do react to HA creams, it is more than likely due to other components of the cream- for example Propylene Glycol, SLS, fragrance, preservatives etc..
Guys, thanks for watching this short video on hyaluronic acid. Cheers,

I’m an Esthetician here in Atlanta, and I looooove watching you explain the science behind skin/products. I’ve learned sooooo much from you and Dr Dray!!! you’re WONDERFUL Dr Lim!!!!!
Iam fed up my pigmentation how can do treatment this pigmentation ..????😢😢😢😢
@@yaniaksogum4899 You should use products with niacinamide or vitamine c (but not these 2 at the same time though)
Dr Lim is fantastic, no comment re the other one.
@@65NART why😱😱 btw I think her videos are too long and poorly edited
What would you say is the best treatment for skin with rosacea that is very dehydrated?
I’d forgotten how good you are at this. Thank you so much for the intelligent and direct style and for all the info we need to make good decisions. You’re the best!
Yay! Finally a new video from you. I love all the little Instagram posts you do, and love it when you have a new video on CZcams. The information you provide is so helpful.
Thank you for your expertise in Dermatology. It reinforces what I was taught years ago. With all the hype in the cosmetics industry it’s important, as a consumer, to have the truth regarding what ingredients actually penetrate the skin surface.
Thank you Dr Lim. Now I know it's best use is after bath and before moisturizer. You're the best!
I am an Esthetician and very much appreciative the information you provide. So happy that you are putting out videos on CZcams again. Thank you for your important (and clearly explained) informative videos!
Thank you for taking the time to teach us about HA's! I especially liked that you explained the how HA's should be used with a moisturizer in an arid climate. I grew up in a humid place but moved inland recently and I never considered using a moisturizer before.
Thank you, thank you, thank you Dr. Lim! Perfectly explained. Great to see you back on You Tube 🤩
The best explanation and advice by a true Dermatologist at last. Thank you so much.
I hope these last few videos means that your are back on facebook. I really missed your great advice. Thanks for the time you put into these videos.
Wow, you did such a great job breaking down the information, and you did it really concise as well! It's more understandable now!
Thank you Dr. Davin. I built my skincare regimen around the basic - Vitamin A, B, & C, because I have watched your previous videos. I also watched videos from other dermatologists & drew conclusions from there using critical thinking though my understanding can be very limited being a layman. Please continue making videos explaining benefits of skincare ingredients in a layman’s term. Learning from you is a great start in selecting products and ingredients for my skin without spending a lot of money.
Short video on the importance of HYALURONIC ACID. Cheers, Davin Lim.
Thanks for in-depth vid on HA. To enhance the penetration of actives, in which order should HA be applied, before or after?
I sent u some a msg on instra. Please help me regarding tanning. I have insdian brown skin but due to sporting and sun exposure in childhood face color got darken permanently :(. Just want my orginal color back.
Hello there just had a question if I'm facial steaming will that help improve the results of my hyaluronic acid facial cream?
I'm always happy to watch! Short or long. Thanks for the info.
Dr Davin Lim thank you
Very helpful information Dr. Lim. I’m so glad you are making videos again!
I liked the way you delivered the message. You are so knowledgeable and you base it from clinical trials or studies.
And you are never been biased with some brands because of the videos I watched they were sponsored.
Thumbs up to you Dr.Lim!
Boy, I’m lucky I came across you, this was very educational and simple enough to understand. Thank you
EXCELLENT break down on HA! Thank you! You answered all my questions!
I learn more from you than I learned in school to become an esthetician.
Thanks Dr Lim. I love the way you explain things in a way non clinicians like me can understand. Kia ora from across the ditch xxx
Always honest, informative and to the point! The best! Thanks Dr. Lim!
This doctor is so smart and knowledgeable. Thanks for sharing the information with us and enlightening us on HA’s, I think I know more about it now and the best video on CZcams explaining ha’s.
And he is back! Cant wait for more content doctor!
Much love from the Philippines.
This video is EXACTLY what I needed! I have been using The Ordinary Skin Care Line for the last 6 months (is amazing), and found that the moisturizer with HA was suddenly not working. It would literally made my face look like I was sweating profusely. It was a hot mess and I dont even use foundation. It's Summer time here in NYC and the worst day had a 97 degrees. I thought it was that the moisturizer was to heavy for Summer, but is the Hyaluronic Acid!!!! Without knowing that it was that ingredient alone, I would have likely purchased another moisturizer with HA. Understanding which ingredient doesn't wirk and why makes such a big difference. You solved my riddle Dr. Lim, Genius! I have learned so much from you I cant thank you enough. Also, I love the Ordinary Line so much I am scared I would be in trouble if they stop making it. I'm looking for other great, affordable products as back up. I also need to mention that I have oily skin. HA may act differently on dry skin in the Summer. Anyway, once again THANK YOU FROM NEW YORK CITY. :)
@Laura the inky is very similar to the ordinary
It's a joy to listen to Dr Lim ! Very informative! A big thank you to you !
Thank you so much for concisely explaining HAs. I had no idea what it was and through seeing in on various beauty channels was contemplating buying something with it. Thank you for shedding light!
Thank you Dr Lim for a fascinating video. As a recently retired nurse in the U.K. I now have to be frugal about my skincare purchases. Thank you so much for sharing your knowledge. I got a bit fed up with some of the Beauty bloggers bringing out the next amazing product that will do wonders for your skin! I now watch you, Dr Dray , and Dr Sam Bunting. I’m 65 and just want my skin to look the best it can. It’s nice to see men taking more care of their skin than they did in the past. When I visited my son Kam in Singapore he said help yourself to any of the skincare in the bathroom cabinet Mum It was like an Aladdin’s cave!
The Best explanation of HAs that I’ve ever heard. Simple and to the point!
Welcome back Dr. Davin!
You are the best dermatologist. We need you in the states
Outstanding explanation on HAs. Thank you.
I enjoy the in-depth information you provide in your videos. Thank you!
I do like HA when using a peel to help rebuild the epidermis. Thank you for your awesome videos and great teaching style. Cheers from Florida
You're a wonderful surgeon and educator Dr Lim !
This video was so helpful 😭😭😭
Whenever I'm looking for skincare products the employees only know so much and they just tell me the benefits but this video explains everything so clearly thank you so much!
You're a good dermatologist I especially love all the useful info you post on Instagram. You and Dr. Dray are my favorite dermatologists.
This was fantastic! Thank you. Knowledge is power
Thank you for explaining when I need a more occlusive moisturizer while using HA.
Perfect video! Explained use of HA so in layman terms - keep these videos coming Dr. Lim!!!
Thank you for this tutorial on hyaluronic acid. I was looking into some serums and creams and thank you thank you so much love your videos just joined love from Austin Texas
Great video. Thanks for your expertise and the ability to communicate in such a clear concise way.
Great information dr davin lim! You’re the best!
thank you so much for such a comprehensive details of HA. being a budding dermatologist i always tell my patients that topical HA cream/serums etc formulation only work as moisturizer n yeah only HA fillers go into the dermis as u mentioned as well.your video served as a quick revision of Rook's last unit as well. thanks again.keep sharing the good stuff.
Thank You Dr Lim for coming back to CZcams, I was wondering if you had heard of the Australian brand of skincare ASAP and your opinion on this brand...Much Appreciated from a fellow Aussie 🇦🇺 from near you...😊😊
ASAP is very popular here and quite ok, I've heard. I would love to try it. Greetings from the South East 🇦🇺
-Nellie -m I’ve purchased few products of ASAP but haven’t tried them yet. I see quite a few ASAP products in his cabinet, maybe he’ll make a video about them. 🤞
Sleeping Labradors I’ve been using it now for a couple of months and quite like it, I was using Zo Health skincare which is Very Expensive, and I Think the ASAP is very similar to that brand, it even has the same texture and smell....the only thing is I wished their Vitamin C was a Serum Not a Cream, But I use them All...Vitamin B, Vitamin C, Daily Moisturiser with SPF, Eye cream, and I’ve just started their Vitamin A at night, But too soon to give an opinion on that one, it’s now sold at a Salon near me when a long time ago I had to purchase it only online which for me is a Bonus because I don’t like buying online products.... I also have the cream cleanser and daily exfoliating cream I use at night...❤️❤️❤️🇦🇺
Thanks Doc, now I have a better understanding of how HA works, and what to get and not spend big bucks on the trendy ha's in the market! Love watching your videos!
I love Dr Lim's explanation of Hyaluronic Acid. Thank you for this simplistic video. 🤓✌🏼👏🏼😊
Hi Dr. Davin , can you also talk about oral supplements of collagen and elastin? Thanks!
Thanks so much! Been thinking of incorporating HA to my skincare.
Great video ! Good and honest info much appreciated for sure. I learned a bit more about H A 👍
I LOVE your videos! You give such complete, easy to understand, explanations about product ingredients, and cosmetic procedures.
Also, giving opinions on what to spend your money on is SO helpful.
Even drugstore brands offer many products, and most well over $10, and many $25+.
Some say they brighten and reduce wrinkles. Others say they reduce pore size, and "rejuvenate", does that mean it reduces wrinkles or does more?
Thank you, this was great information. I also like the Ordinary.
Thank you for some good knowledge!!! I definitely need to know about this! 💯 🔥
It's truly passionating to listen to what you say! Im getting interested in dermatology :) Thanks for your honesty!! :D
Thanks doc for the constant information, you really look amazing with your gray hair.
Thank you for making this one in particular. There's so much confusion surrounding HA. I use the Good Molecules HA which is around 8 bucks. I apply it to moistened skin (hand held fine face mister) and then mist lightly after applying. I then use my TGF, Vitamin C and an occlusive moisturiser to seal it all in. I use the Violetta sunscreen (Aussie brand. Goes on like a serum.
I'm so happy you're back on Y. T. I was initially confused as in the UK this is pronounced hyaluronic with an R. Once I got to the molecular weight part I realised its the same thing. Thank for an excellent top vid Dr D. XOXO
I feel like HA is gonna pull moisture from deeper layers of the skin, pull it to the surface of the skin and make it easier for your moisture to evaporate into the environment.
Thank you for explaining HA's. Your video helps me explain HA's to my readers in my blog
Thank you Doc! I was cheking RealMe, and noticed that your personal results with Infini are better than the other docs, is it because the golden tip is burned and not working like its supposed. Should I ask to see that part? Thank you!!😊
Thank you for dispelling some myths regarding HA's and their effects on skin and the claims some companies make. I've learned to make my own serum using HA powder in multi weights using distilled water and glycerin. I don't let it dry out , rather keeping it moist with homemade rose petal hydrosol for 20 minutes. Using distilled water to rinse is key I think. I had Juvederm for volume loss in the apples of my cheeks and cheek bones and did last 2 years. However it's quite expensive though they did look great! Thanks again for another great video!
Why DIY it and not just buy a product?
Starlet :D That’s an odd question. I would think natural would be better.
@@jojomakes Just because it's "all-natural" doesn't mean it's better. Just because it's a "chemical" doesn't mean it's dangerous. Everything is technically a "chemical" and nothing is truly "natural". We are a chemical, water is a chemical, everything is a chemical. Cyanide is technically considered natural but it can kill you. Anything in a high enough concentration can kill you. It's more of a myth / fear-mongering / marketing tactic that "natural" is better. It's been spread by the media and now it's gone too far. In my opinion, I feel it would just be easier, safer, more efficient, and even possibly more affordable for her to buy a product that contains that ingredient then make it herself. Products are created in a lab by chemists who are experienced and are trying to formulate this for human skin. That often doesn't translate over to DIY skincare. But to each their own 🤷♀️
Great video thanks good to see you back 😊
🇨🇦. Hey from Toronto......love your videos...I take your words to heart and believe everything you say..I have been.a nurse for more than 40 yrs and not all docs are like you
Your videos are packed with amazing information. Thank you so much for explaining the complicated subject of skin care. 😘
Hi Dr. Davin, is it possible if you can make an explanation about FUNGAL ACNE? Thank you 🙏🏻 lovin’ your channel very informative. 🤗
I much prefer dr to talk about this....glad to found you!
Awesome info.
Keep it up Dr. Davin. Thank u so much.
As always such a great in depth video. Thank you! Question...in what order should we apply our skin care, so that the H Acid helps other actives to penetrate deeper. I use HAcid first thing in the morning...however in the evening fistly i use tretenoine 0.1% , then follow with H Acid and moisturizer lastly.
Thanks for your informed advice! I am currently a med student looking into dermatology as a specialty :) just wondering, what are your thoughts are on using hyaluronic acid in conjunction with derma-rolling and skin needling, and whether this is any more effective without having to use fillers. Thanks again!
So informative and honest - Love it
No lie. This was a good video!!!!! Love you! I need fillers in my life.
Davin Your hair looks Great. I love it! My husband has the same salt n pepper hair. He was thinking about dying it and I quickly stopped him. It is very attractive.
Thank you Dr. Lim. What’s your take on Squalane oil does it have the same effect as HA?
Good question
Always honest and informative. Thank you.
This was very helpful. I'm going to start applying my HA serum before I apply my Retin-A! Thanks, Dr. Lim!
I believe Retin-A should be applied on dry skin; no?
@@mnmira001 Yes, ideally, it should be applied to dry skin as a first layer. That's what the directions say on the label, so I'm going to assume that's the best way to use it. You can apply moisturizer next if you like. That's what I've been doing! I want to make sure I'm getting the best results, so I think it's important to follow the directions on the label.
Hi, Dr. Lim. Thank you so much for great information. one question though! How HA can act as an agent to deliver other nutrients to deeper level when HA itself cannot penetrate into deeper level of skin? Thank you so much!! :)
Davin, Thank You for your explanation on HA. I'd like to know what your filler of choice is for nasolabial folds?
Good informative about HA. Thanks for sharing Dr Davin
he's backkkk! You should go on a world tour, Dr. Lim! We luv you!:)
How about the effectiveness of HA when coupled with 0.25-0.5 mm microneedling? Will it still be an effective moisturizer when used in dry climates?
Thanks so much for your educational videos I love them!
I love your channel, it is very instructive.
Thank you for sharing your knowledge with us. 👏👏👏
Wow. I am shocked by the quality of your video and the level of information. Thank you for sharing.
Great to see you again and besides loving your videos your hair aint half bad either. Goodnight fromCalifornia
How often should you apply Ha serum, and is there any peptides or acids etc that can have a tightening effects for your neck , also what other serums go well with ha thanks 😊 I use the ordinary ha
Your face skin looks GREAT, Dr. Lim What is your AM/PM skin routine?. Question: Does applying HA after micro-needling of 0.25 or 0.5 mm help more penetration to the dermis or it still stay in the epidermis? For this, I have been using MULTI-MOLECULAR HYALURONIC COMPLEX (MMHC) from The Ordinary-NIOD. The Ordinary description on their HA says that the MMHC is a stronger combination of HA. What are your impressions on it? Also, The Ordinary has expanded a lot their line with their other name brands (NIOD, Hylamide) at a higher price.
One video said HA by itself wasn’t necessary as HA is in a lot of products. Made sense so I stopped and was sure to have products with HA in them like face cleaners, moisturizers and some cosmetics. Nope, for me it wasn’t enough. I’m back on The Ordinary’s HA. Yay! Feels wonderful. Thank you Dr. Lim.
Thank you for the great information, as always!
I love your videos and always found them informative. Although, this video I felt was a little bias towards a product you are trying to sell..."injections."
There is scientific proof that using HA's after microneedling allows the HA's to penetrate in a fashion similar to that you described by your injections.
Would you clarify for everyone?
I know this isn’t your first video since your break. But am really glad you’re active on CZcams again. Love from Singapore
Thanks for the well wishes, cheers, Davin
Thank you Dr. Lim, this was very informative and educational.
Thank you do much. Love how you just get straight into!!!!
OZZY!!! OZZY!!! OZZY!!! OYY OYY!
Thanks as always Dr. Lim. My favorite topical is actually Neutragena and Hada Labo. Reasonably priced and good products.
As always, great content! You've enlightenment me about HAs and saved a lot of people from getting their money down the drain.
♥️🇵🇭
I’m working as laser and beauty therapist in UAE. I'm so glad i found your channel, i love watching your videos doctor. I learned a lot from it! Thank you ❤️

Thanks for the info on how they work in different climates! I live in the NT and it’s dry season, and I couldn’t figure out why my face was as dry as a chip even after all my serums/ creams! Will need to slightly adjust what I’m using. 👍🏻
Hi Dr can you please talk about keloid and ways to reduce its size? Thanks love your vid
Hi Dr, if it's ok I have a few random questions for you if or whenever you have the time to answer: First, how often should someone wash/cleanse their face?--particularly, how much is too much? What's your best tip for repairing a damaged skin moisture barrier? And what is the ideal age to introduce retinoids into skincare? Thank you for your insights!
Twice a day. Depends on your skin sensitivity, as for repair, well atopic dermatitis has MAJOR barrier disruption. For those patients we use simple emollients. WSP. CETAHPIL, and many other simple formulations. Retinoids - late teens! DL
@@drdavinlim Thank you, much appreciated!
Top quality information Dr Lim. Thank you 😊
Thank youuu for making this!!
Thank you for this video.. I won’t be spending my money on serums any more.. I’ll stick to CeraVe moisturizer.. again thank you for the great information 👍🏼👏🏼👏🏼
Cerave moisturizer isn’t very good . Use serums .they are very moisturizing
So should the HA go on before or after your actives? Or does it even matter?
Dr. Lim, so good to see you again. For someone who has never used HA, is it safe for them to use it alone in their skincare routine? Thanks for all the well explained info.💖
Very informative! Thanks for sharing!
