In a 12-week clinical study, H.A. Intensifier significantly improved the appearance of key aging indicators:
Protocol: Average results shown. A 12-week, single-center, clinical study was conducted on 59 females, ages 42-60, with mild to moderate facial sagging and loss of firmness, rough skin texture, nasolabial fold wrinkles, marionette lines, and presence of fine lines/wrinkles in the crow’s feet area. H.A. Intensifier was used twice daily in conjunction with SkinCeuticals Gentle Cleanser and a sunscreen. Efficacy and tolerability evaluations were conducted at baseline and at weeks 4, 8, and 12.
Hyaluronic acid naturally occurs in the skin and plays an important role in maintaining moisture. This essential molecule however has a short lifecycle in skin, with 30%-50% degrading every 24 hours. With age, the skin’s ability to produce hyaluronic acid decreases. Production starts to decline in the 20s and this decline accelerates in the 40s. Decreased production rapid degradation of hyaluronic acid contribute to signs of aging, including decreased firmness, less facial plumpness, and rough texture.
While hyaluronic acid is a powerful hydrator, the size of the hyaluronic acid molecules are too large for optimal skin absorption. H.A. Intensifier uniquely combines surface-hydrating hyaluronic acid with 10% proxylane™ and an optimal concentration of licorice and purple rice extracts to support skin’s hyaluronic acid levels.
- 10% Proxylane™
- 2.0% Licorice Root Extract (dipotassium glycyrrhizate) + 0.2% Purple Rice Extract
- 1.3% Hyaluronic Acid

Rated 5 out of 5 by Lomicka from Marvelous Product for Aging Skin At the suggestion of my skincare professional, I started using this product in conjunction with the Replenishing Cleanser Cream (started first) and the Triple Lipid Restore (added second). Until I added the Hyaluronic product, there was minimal difference. Adding the Hyaluronic made ALL the difference. In a month, my skin was plumper, smoother, more supple and no longer dry and dull. I am 68 years old ... and live in a dry climate 6 mos of the year. I do not have a lot of facials, but I do have a machine micro dermbrasion every three weeks. I use the Triple Lipid Restore in the morning right after cleansing. After five minutes, I apply my usual moisturizing products on face/around eye. At night, I do the same but replace the Triple Lipid with the Hyaluronic.

Rated 5 out of 5 by Maddy from One time only Amazing! I received a sample through mail. I thought well why not give this a try. My skin is very dry and damaged from cancer treatments twice and radiation. Now diagnosed with Sarcoidosis also affecting my skin. I have a constant layer of dry skin. I used the serum and that whole layer of dry skin just came off. I haven't been able to use makeup in a very long time. My dry skin just looks worse and makeup makes it look more visible. Really notice a change this might be the product my skin needs. Sadly I immediately came online to see where I can purchase and I couldn't afford this. Thank you for the sample

Rated 2 out of 5 by Anonymous from Great product. Package fail I have used this product for a month and although I do like it a lot, I will not purchase again because of the packaging. It is misleading how much actual product you receive. It appears the bottle is full but when I could not get more out of the pump, I opened it up and the product is contained in a small plastic tube inside the bottle. I love the skinCeuticals products but this one is a miss.

Rated 5 out of 5 by Cho from Perfect For Firming and Creating a Healthy Glow! I received this product as a free sample for testing. I loved it so much I had to purchase a full-sized bottle! I use this serum in the morning and at night before I go to sleep. The elasticity for my skin has been drastic and I keep it in my fridge and use it cold! This is my pro tip for all liquid products for my skin care. I really like this product because it has given me a healthy glow in the past couple of weeks that I don't find during the dry, winter season!

Rated 5 out of 5 by Chelle from Love it! It is definitely worth the investment. My skin is so much smoother and it glows. I have a pretty good skin routine however this stepped it up a notch. I get compliments every where I go. I'm all about prevention so this is a added bonus and no one believes my real age! You can call me the Black Jlo(love her).. Note, I do get facials every 2-3 months, I workout, I drink cerely juice, I sauna bath, and I take mineral supplements :) All work together

Rated 4 out of 5 by Alves from Anti-aging Let me preface this by saying that I didn’t give it 5 stars because I haven’t used it long enough to see concrete results. I have given this product 4 stars because I am happy with what I have seen. I’m at the age where I want to prevent aging (don’t we all) and so want to use products that will aid in sag and crows feet prevention. After cleansing my face, I apply this product one a day before bedtime after using retinol. I have found that my complexion has improved and my face feels firmer, especially around the mouth. The serum has a gel-like consistency and absorbs pretty quickly. It feels hydrating and I can tell that it is from the glow that I can see when I wake up in the morning.

Rated 3 out of 5 by Wheels from Wonderful product—absolutely horrible design I absolutely love this product. However, the packaging in the bottle will not allow all of the product to be released. It is unlikely that I would purchase again with such a poor design. At this price point, product should not be “captured” in the bottle and end up in the trash.

Rated 4 out of 5 by Lucky from Hydrating Serum I got a sample of the HA Intensifier with a Skinceuticals purchase I made. I'm not sure which product, or if the combination of products, gave me results, but I have seen results in a short amount of time. My face was uncomfortably dry and tight. Since using this product, my skin feels healthy and looks dewy. I also have extremely sensitive skin and will get rashes and hives to certain ingredients, but have had no reaction to Skinceuticals products! This serum is not a liquid like other serums - it has a milky consistency and no smell, which is a plus!

Rated 5 out of 5 by Reed from LOVE THIS! I've been using this serum for at least a couple of weeks now and really love it. I put it on at night with my other nightly routine and I can really tell the difference in the morning! I forgot it the other night and knew exactly what I forgot when I got up! It is a really good primer for your foundation in the morning, it gives a nice glow! This is one product I don't think I'll be without in the future!

Rated 3 out of 5 by Candy from Causes sunscreen to rub off and pile on skin Love the texture of the product and the feel of it on my skin. The problem I have is when it’s applied under my Skinceuticals sunscreen it causes flaking and piling (sort of the appearance of dead skin flakes). When I use it at night, without sunscreen, there’s no piling. I’m assuming that the two products don’t mix very well. It’s very frustrating because I love the product. Unfortunately, I probably won’t order it again.

Rated 5 out of 5 by LJC1 from amazing! I recieved a free sample months ago. It was only enough for 2 or 3 uses, but I was really impressed with how my skin looked! This product is out of my price range, but I bought a full size bottle anyway. I'm getting nervous because its almost empty, but it did last for months and I LOVE it. I'm 45 years old and I feel that it helps me look 10 (or more?) years younger. My skin is smoother & fine lines have seemed to fade. If you're looking to splurge on an amazing skin product, this is a good choice.

Rated 4 out of 5 by Roberson from A Solid Serum for a Well-Rounded Skincare Routine The difficult thing about receiving samples to review is that sometimes you get a product that really requires long-term use to give a solid review. This serum seems like a solid purchase for people living in dry climates or treating their wrinkles. Hyaluronic acid essentially pulls moisture from the air into your skin, plumping it from the inside out, so, really, regardless of your skintype, age, or concerns, you can't go wrong with this serum. And, because I find that a lot of people don't know when to use serum, it goes: wash, tone, essences, serums, moisturizer.

Rated 4 out of 5 by Barr from So good! The coverage and feel of this foundation is amazing. It’s literally weightless and leaves your skin with a natural finish. The coverage is incredible, though it’s most definitely full coverage it leaves your skin looking as if it is your own. My only complaint is that it does cling to dry patches. I tend to have dryer skin in the winter and unless I exfoliate more often this could resent a problem for me wearing it. Otherwise this is a great foundation with an admirable shade range. I did receive this product as a free sample in exchange for an honest and thoughtful review. I received this product complimentary for review purposes.

Rated 5 out of 5 by Bootsie from Works well My dermatologist recommended this product to me. Using the first bottle, my skin felt better, more comfortable and soft to the touch. I’m now almost done with my second bottle, and now I am able to see a difference in how my skin looks. I have deep lines around my mouth, and they are definitely less pronounced. My neck and under my chin are a bit saggy and prone to chafing, The area appears a bit more firm, and the chafing has subsided, making the area appear smoother. I will be getting another bottle!

Rated 5 out of 5 by Happyme from Love it! It’s been 3 weeks since I started using this product am/pm. I should also mention that at the same time I introduced the Glycolic 10 at night to my regime as well. The clincher was a comparison photo that was taken at my dermatologist’s office 8 weeks ago. What an improvement! My skin is much firmer, feels smoother and no breakouts, no peeling. I can’t say whether it’s HA or the glycolic serum at night, but I won’t be without either one from here on in!

Rated 5 out of 5 by Stylist 333 from Moist! After my 1st try on CE Ferulic, I have decided to try other product. I heard people are telling me that hyaluronic acid is a great thing to use on routine basis. Especially because my skin is on the dry side when traveling, I got HA to use at night before my mosturizer. I love it! It gives me dewy look when applied. Next morning, I notice my pores are smaller & very fine lines of mine disappear. I am hooked on another Skinceuticals product.

Rated 4 out of 5 by Schuring from Revitalizing and brightening! I received the Hyaluronic Acid Intensifier complimentary and I really enjoyed this product! My anti aging concerns are mostly the areas around my eyes, fine lines and general sagging and a tired look. I applied the product to my entire face and I loved the bright tone I immediately noticed and the fresh look it gave me. I first used it before applying moisturizer but found that it applied better when I mixed it with my moisturizer. I did notice that the area around my eyes was looking fresher and healthier, though I'm not sure if my complimentary sample was enough to begin to see a full difference. Overall though, I seriously loved the way this product left my skin feeling and looking.

Rated 5 out of 5 by Whit from Less wrinkles! I love this product. I studied for months before I purchased (because of the price), and I have not regretted the splurge one it. I've had a little over a month and I have a lot of improvement with the wrinkles on my forehead and my crows feet. This is now a necessity!

Rated 5 out of 5 by Bonbon from Helps smile lines This feels thick when you put it on but then melts in. There is no real small or tackiness after application. I think my fine lines are significantly better after using this for months and unless the winter is very dry mostly don’t feel the need for a moisturizer

Rated 1 out of 5 by ChristineC from Cannot tell a difference Honestly, there are Skinceutical products that are amazing and some that I cannot tell a difference. My intention is not to discredit the product, I just cannot notice any changes in my skin after using the product.

Rated 5 out of 5 by Evans from Love! Received a sample size complimentary to review. Not sure if I’ll be able to use long enough to see full results but honestly loved the product right away. Feels great on skin and saw my dry areas feel and look so much better. I have sensitive and acne prone skin but this has been gentle and have seen zero negative side affects.

Rated 4 out of 5 by marie52 from Good but could be great I like this product and how it feels. Too early to tell on long term results but I love most SkinCeuticals products I have used. What is keeping me from loving this is the dropper bottle. It seems like it would work much better in a pump type bottle like the AOX Eye Gel. That is a big negative for me and could keep me from repurchasing.

Rated 5 out of 5 by Britto from Glowing skin I love how soft my skin felt after just one use. I have sensitive skin and thr product was not drying or oily which i liked very much. The product is a bit thick but once its on the skin it applies very smoothly . After two days of using the product my skin has an even tone and a great glow which i love .

Rated 5 out of 5 by DAwn from Amazing products I bought the daily and night moisturizer along with CE ferulic and absolutely LOVE every product. The cost is pricy but definitely worth it.

Rated 1 out of 5 by Racich from Not my favorite Skin Ceuticals serum I have used two other SkinCeuticals' serums, which I like very much. I purchased this one with high hopes, but it feels like sticky grape juice on my face. I find that I can't apply any other products over it and it feels like it is just sitting on my skin and not absorbing. I will not purchase this one again.

Rated 5 out of 5 by Spry from So moisturizing! I received a sample of this product from Influenster and Skinceuticals to try for free. I decided to try this product on a day my skin was really angry at me. My sensitive skin had been put through the ringer yesterday, applying 2 separate make up looks. It was extremely cold when I went out and about today. Tonight when I put this on before bed, it felt amazingly moisturizing. It felt so nice going on my sensitive and angry skin. I know that this product will be wonderful to use on a daily basis and keep my skin looking and feeling great!

Rated 5 out of 5 by Youngdad1981 from It works! I'm a 37 y.o. guy and only started taking care of my skin a few years ago when I started noticing evident signs of aging. I've always been suspicious about skincare products, but my dermatologist recommended H.A. intensifier together with a skincare regimen and I gave it a try. I can confidently say this product works. My skin looks less smoother and younger in general.
