SkinCeuticals H.A. Intensifier Multi-Glycan Plumping Hydrating Serum

My skin looks and feels much fuller and more hydrated since starting this product. My makeup goes on effortlessly and appears much more natural

This product is a little tricky. I applied it in a damp face, moisturized on top, but continued to experience moderate dryness and flaking. Not sure if it's user error or my sensitive skin. Overall, don't think I would purchase.

In general, I really like SkinCeuticals products. For some reason, this stuff did not resonate well with me skin. It felt very sticky, the smell was not great, and my skin did not feel plump or seem to have any positive benefits. I didn't have anything negative with my skin, but it wasn't something I would spend money on.

This is a smooth and wonderful smelling serum. Very light and works great under makeup.

I was gifted the Skinceuticals HA Intensifier in exchange for my honest opinion, and I was really excited to try it as someone in their late thirties with dry skin and fine lines. I've used other Skinceuticals serums, as well as other HA serums, and there are definitely some aspects of this product I'm really fond of. I like that it's viscous enough to easily spread around your face and neck, and the dry down time is slow enough to feel like you got good coverage. I did notice it gave my skin a bit more "bounce" (which went away after discontinuing use, fwiw). The big drawback is the price— I'm on the fence about whether it aligns with the level of results I achieved. But if price isn't a dealbreaker, it's worth a try!

I like this product and I liked it’s previous version.

First off, the texture of this product is divine…it's thick, cushiony, and glossy. It's very easy to apply, and the bottle and dropper are obviously of high quality. It does feel hydrating on the skin and is a pleasure to apply, however, I didn't see a difference at all in skin hydration after weeks of consistent usage. This product is advertised as but one step in a multi-step regimen, so maybe usage with the full product line would yield better results. The product is rather pricey, and I can't say that I would purchase it myself when there are much cheaper and just as/more effective hyaluronic acid based products out there.

This serum is seriously great! I immediately noticed the plumping action. It is fragrance free and feels so soothing to apply to skin. After several weeks of continued use, my skin has a glow and feels softer and smoother. I would definitely purchase this product when I run out. I did receive this serum for free in exchange for my honest review.

I was really excited to try this brand which I have not used before. First off I have combination skin that is medium skin tone and I'm reaching my late 30s so fine lines are a major concern to me so this product had great interest. I like that it had no smell and that it was light on my skin however I felt like the product didn't absorb quickly into my skin and felt like it was sitting on top of my skin. I didn't particularly notice any plumpness in the two weeks that I use the product in my morning skin care routine routine however I plan to continue to use the product for 12 weeks to see if I see any improvement in my fine lines and hope that the serum is a win for me in that area!

This made my skin feel Devine. I very much enjoyed the result. I was left with plumped/glowing skin. It feels so hydrating!

Thanks SkinCeuticals for the free HA Intensifier Multi-Glycan! I've used it for couple weeks & my skin is definitely moisturized & radiant. I use it in the daytime after using my Vitamin C. Very highly recommended!

I have tried the Skinceuticals brand before so when I was offered the opportunity to try the HA Internsifier free in exchange for my honest reviews I was thrilled! The brand has a great reputation as high quality and effectiveness and this product is no different. I have combination skin and I tell you what - I didn't see a single flaky spot or dry patch for the 3 weeks straight I used this product. And that's with using my 5% tretinoin prescription retinol every other night which always dries me out! A little bit of this goes a long way. It's not greasy under makeup and doesn't pill up or flake off or leave any sort of residue. Highly recommend and will be purchasing on my own to add to my skincare arsenal, I can't wait to see how this works on my parched northern winter skin!!

First off, this is a terrific brand. I love the emphasis on innovation and science-driven formulations. I've tried a few products over the years and have been impressed with all of them. This serum comes in a dark glass bottle and uses a dropper to dose the product. The product itself is a darker color and is very smooth and blends well. It's potent and powerful, so a little goes a long way. I initially used it twice a day but pulled back to every other day until my skin got used to it. From there, I now use it as part of my daily routine. I even use it on my neck and chest - always a good practice to remember that skin!

Thank you Skinceuticals for the free product! I have used it for about three weeks so far as part of my nighttime routine (cleanse, exfoliate, serum, moisturizer) and I have definitely seen noticeable results. I get Botox in my forehead and right when I received this product I was starting to notice those fine lines coming back (it had been about four months since my last injection). Since I've added this product to my routine, those fine lines are definitely less visible and I will continue to use this to extend the life of my Botox treatments! It does not make my face feel sticky at all like previous products I've tried, the smell was a little intense (not bad) but went away in a couple minutes. I would completely recommend this to anyone who gets Botox!

This serum is a miracle worker! Since I've been using this in my routine, my skin dehydration has practically disappeared. My postpartum skin has been particularly dry and I thought I'd never getting my moisture and plumpness back until this serum came along. It's a must have for dry or dehydrated nature skin!

This serum is thicker and less watery than most other serums I've used. It spreads easily, a little goes a long way. It also works well with other products. Upon use, my skin feels more moisturized. Over time, I noticed more plump skin and a reduction in fine lines specifically on my forehead and neck/chest.

I don't normally take before/after photos when trying new products, but I really wish I had with this! I already have a pretty extensive skincare routine (37yo and trying to avoid needles for as long as possible). I've had a couple very faint forehead lines for a while, and they are now almost completely gone after about 2 weeks. My smile lines aren't as deep, and even some of my acne scars are less visible. It is a thicker serum, but it doesn't feel sticky and it smells nice. I'm thoroughly impressed.

I have used many skinceuticals products in the past and yes, they are pricey, but also- yes, they work. I was skeptical about this HA at the pricepoint so I've given it 3 weeks to use the project to properly review it. Here are my takeaways: At first, it felt a little sticky and not as moisturizing as other HA products I use. However, my skin was immediately glowing. Was this worth that sticky feeling? I had to keep using it to see. Day by day my skin was really looking more vibrant but I still didn't love the sticky texture and wasn't putting makeup on top because I was nervous of pilling. Ok- here's how I fixed that and now LOVE the product; I actually wet my skin first, put a liquid toner and keep my skin wet, THEN apply the product when skin is still damp. Wow, this changes things. I instantly didn't feel like sticky feeling and was able to reap the benefits of a glowy skin as well as a perfect base for makeup. Something about applying to damp (almost wet) skin changed the game for me with this product. Now, I'm 3 weeks in and honestly don't want this bottle to end! I just hope it will last me at least 3 months. The only reason I didn't give 5 stars is because it wasn't clear to apply on damp skin and the price. I did receive this product through a promotion but I think I would repurchase if I'm still feeling these same results, especially since I currently don't want the bottle to end!

I love this product. It is a nice thick serum so a little goes a long way. It does not feel heavy on my skin, it leaves my skin feeling hydrated without feeling oily. Lastly, there is no odor to it which I personally really like in a skin care product.

I received this in exchange for a review and I used this product for about two weeks to give a real test. Sometimes used AM, other times PM. It really did help plump up some fine lines, especially the horizontal ones on my forehead. No negative reaction at all and I'm pretty sensitive! Noticeably more effects than the French pharmacy brand I was previously using. I would purchase this again if budget allows!

I have been using this product twice a day for the past two weeks. It's incredibly lightweight and glides on my skin easily, without leaving a tacky residue. While I would not claim that it has drastically changed my skin, I have noticed that my skin tone is more even (less red) and that my skin does feel quite hydrated. I am hoping that with continued use, I may also notice reduced wrinkles (especially around my mouth). Overall, this is a product I would spend my own money on (I received a free sample from Buzzagent in exchange for a review).

Literally my face felt like heaven even after the first use. It's so soft and plump. My dehydrated lines on my face are already less noticeable after a week. I would repurchase this product and get more from this company. This is the best on the market!

I use this product twice a day and my skin looks so plump, refreshed, and smooth. I am overdue for Botox in my forehead and you really can't tell because of this product. This has become my favorite skinceuticals product and is now a staple in my routine.

I've used this about two weeks and haven't really seen a difference. It does increase hydration and my skin feels soft. Other than that, I'm not really blown away. I will continue using this to see if I noticed a difference.

This serum is great as I felt it tighten my skin. I only used at night as when I tried it under makeup, it ended up pilling. Definitely a new addition to my nightly skincare routine.

I am a huge SkinCeuticals fan so I went in with high expectations. The product definitely left my skin bouncier and noticeably softer. I didn't see changes in my forehead wrinkles BUT I don't think I tested the product long enough to see a difference. I will definitely keep using it.

After just a few uses I could feel my aged skin become noticeably plumper and more youthful

Great everyday product to add to your routine. My skin is feeling more moisturized and bright. I feel a lot more comfortable without makeup because my skin is plump and it somehow looks smoother. Hoping to see diminished wrinkles the more I use it but it is absolutely more plump!

l've been using this amazing product in the mornings before placing any moisturizer and spf and makeup. This has been a game changer on my skin. My skin has never felt hydration like this before. Recently since using this product l've been complimented daily. I look more well rested and refreshed. SkinCeuticals products has yet to fail me. I've been impressed with each product I've tried. I've tried many high end products and this brand has not disappointed. This hyaluronic acid in this product has a high concentration that delivers.

I was given Hyaluronic Acid Intensifier Multi-Glycan to try in exchange for a review After using HA Intensifier Multi-Glycan for 10 days I have yet to see results. Although, what product really works in that time period. It feels nice, not oily, scent free, and a little goes a long way. Will continue to use since there have been no adverse reactions.

SkinCeuticals HA Intensifier Multi-Glycan Serum is a very nice product. It absorbs into my skin seamlessly and does not pill. It works well with my moisturizer, and I feel like my skin is more moisturized overall.

This serum is lightweight and non-greasy. It is thicker than a lot of serums so soaked into my skin a little slower than some serums and a tad bit sticky. Have noticed an improvement in my skins hydration. Hoping it can minimize my fine line appearances. Have not seen that effect yet but hoping to with continued use. I love SkinCeuticals scientific research to great products and this is no different

I have been trying it out by replacing my usually HA and I really like it. I don't use too much, just 4 drops at most. I once used more and my other skincare pilled overtop. It makes my makeup go on smoothly and my face seems to be looking clearer, however I've only been using it for about a week, so we'll see!

I love Skinceuticals and was so excited to try the HA intensifier. I've been using it daily for about a week in the morning under my moisturizer. The bottle says 4-6 drops twice daily to face and neck but I've been using about that amount once a day in the morning and it feels like plenty. The short term effect is that my skin is so soft and glowy. It's similar to the effect I got with the B5 but this one states it has more anti-aging elements so longer term it should work on fine lines. I have adult hormonal acne and this has not triggered any flair ups. Texture is a little bit sticky at onset but then it soaks in and doesn't leave any lasting oiliness or stickiness. Once it is absorbed, my skin looks fresh and healthy. The serum is also fragrance free like other Skinceuticals products so it's not harsh on my skin.

I was hoping I wouldn't like this product, but I love it. Not sure why I'd doubt the brand that is always exceeding my expectations. The volume and plumpness were evident the first time I used it, but the good news is I don't need a lot of product which makes me feel good that it will last me awhile. I'm 44 and elasticity and hydration are what I'm desperately in need of. This gave me the results that I haven't found with any other hyaluronic. Get your hands on some if you can. You won't regret it.
