I received a complimentary sample of the SkinCeuticals HA Intensifier Multi-Glycan in exchange for my honest opinion about this product.I'm a 45 year old woman who regularly gets Botox filler, which does a good job of controlling the major wrinkles, but I'm still always on the hunt for that youthful glow & plump skin that seems to be a thing of the past. This product, which I've been using 2x per day for 2 weeks may just be that magic potion I've been searching for! Within a day or two my skin began to regularly look like I've gotten 8+ hours of sleep and drank all the water I'm supposed to drink each day.

I've used 4 drops at each application, allowing it to fully dry before applying moisturizer. It seems to help with moisturizer absorption as well & I'm obsessed with how fresh I look each day.I'm not someone sensitive to fragrance or with sensitive skin. But I did not notice any fragrance whatsoever and I can only describe the texture as silky. My makeup applies the same as it always has since using the product, and if anything, I'm finding I need less because I don't have much I need to correct.It's taken me many, long & expensive years to find those products that just work for me, and this is being added to the list. Try it... you won't be dissapointed!

In the last year I have noticed my skin aging much more - I have dryness and wrinkles that weren't there before, and they can cause makeup to sit or settle poorly. I don't know how, but this does "plump" my skin and hydrate (in a not oily way) to help my texture. It doesn't fill the wrinkles like a primer, but instead plumps from the inside out to hydrate and firm the wrinkled and dry areas.Important to note that even on first week of use, this did NOT break me out or cause any reactions, which is always a concern for me when adding a new product.I did receive this product for free in exchange for my honest review. Honestly, I didn't really understand the claims when reading about it, but I trust skinceuticals and was very excited to try. I will continue to purchase this product. I think it will be an important addition for my skin concerns.

I have always wanted to try the brand SkinCeuticals, the reviews for this brand have always been great. Unfortunately I found myself always picking a different skin care product that was more affordable. When SkinCeuticals gave me the opportunity to receive a free bottle of their HA Intensifier Multi-Glycan and in return I would leave an honest review I was super excited. I did wait a little longer to review this product, I wanted to have enough time to use the product so I could leave a honest review. When I first started using I had just gotten over a cold, so my skin was dryer than normal. The HA intensifier feels expensive when applying, it had a silk like consistency.

After my first application of the HA Intensifier I did notice that my skin was more plump and soft. I was able to apply my moisturizer, sunscreen and primer after with no pilling. After using for a few weeks I can honestly say my skin is softer and more plump. I was kinda hopping I did not like it because I knew once I did I would have to purchase a bottle when this one ran out. I am even more now intrigued to try their other products. The only down side is the price and size of the bottle. It is by no means a small bottle, just would like more for the price. I would recommend this product even at the high price point, sometimes you have to pay for high quality good ingredients.

I was hoping I would be unimpressed by this product because SkinCeuticals is outside of my typical budget. But it actually works, and quickly!

I received a free sample in exchange for my honest review and couldn't wait to prove that there are affordable alternatives that are just as effective. But...this stuff actually works. I haven''t tried anything else from SkinCeuticals, just this hyaluronic acid multi-glycan, and I am sold. I've used HA before but this is leaps and bounds ahead of any other acid serum.

I haven''t tried anything else from SkinCeuticals, just this hyaluronic acid multi-glycan, and I am sold. I've used HA before but this is leaps and bounds ahead of any other acid serum. This serum has Proxylane in it, which I was unfamiliar with. Also known as Pro-Xylane, it is a sugar protein taken from beech trees and stimulates water-absorbing molecules in yout skin. This is supposed to be what improves firmness. I assume this is the ingredient that made such a noticeable difference for me, as I've tried HA serums before but not had the immediate results I did with this particular blend.The serum itself comes out heavy---it feels dense in the hand like a corn syrup. But it isn't sticky and absorbs beautifully, with a texture that feels like velvet. It has a subtle purple tint (licorice root and purple rice are ingredients). I put it to the test by adding it to my skincare regimen during a 2 week roadtrip around the American Southwest desert. My skin usually shows immediate signs of dryness, but with this serum onboard I was excited to see more plumpness and even some fine lines filling out. A little goes a long way. I'm happy the product works, but my wallet isn't...because now I'm going to be spending a lot on SkinCeuticals!
It's been a bit of time since SkinCeuticals generously gifted me this lovely HA Intensifer Multi-Glycan. Long enough, I feel, to accurately assess the effects of the product, and whether or not it is suitable for my skin.I typically introduce new products one at a time, and test for approximately a month before determining if there's any negative reaction. Also, this is enough time to observe longer term positive effects. (Not that I don't love a mask or serum that leaves me with an instantaneous glow!)When I introduced this intensifier, I was dealing with enlarged pores, as well as more dehydration than usual from a peel. I slowly began using this every several days, after my AHA or retinol product, but before my moisturizer and sleeping packs.I noticed ...

Also, this is enough time to observe longer term positive effects. (Not that I don't love a mask or serum that leaves me with an instantaneous glow!)When I introduced this intensifier, I was dealing with enlarged pores, as well as more dehydration than usual from a peel. I slowly began using this every several days, after my AHA or retinol product, but before my moisturizer and sleeping packs.I noticed within two uses that the pores on my nose were significantly smaller, and my skin was tighter. (Products containing retinol do this as well, but I'd already been using one and was still struggling.)i was unsure about applying on my nose, since it doesn't suggest doing this in the instructions—but I'm glad I did! I also only just noticed it can be applied on the lips—so I intend on doing this next, in the morning, before I use my lip butter.As far as texture is concerned, it is fairly standard as far as serums go. I found it pleasing—not too sticky and cool to the touch. More importantly, it didn't cause any piling in my evening stack. I do not think I'd attempt to use this in the morning though, My moisturizer is a water-based gel, and my sunscreen functions as a gel and primer; so, I do think this HA intensifier would work nicely with them. No big deal, though!I had never heard of "propylene" prior to receiving this, nor had I tried or seen a product with purple rice extract. Science and skincare go hand-in-hand, and brands like SkinCeuticals offer products that are not only effective, but treat the customer with respect, offering science instead of glitter.
As a long time user and wholehearted believer in the brand, SkinCeuticals stands apart because it focuses on putting out scientifically backed products. I always enjoy reading the background about why certain ingredients are in each serum I purchase. This medical skincare brand has really left all other brands in the dust with their potent, powerful formulas. HA Intensifier Multi Glycan is a perfect example of an unbelievably effective update to a favorite holy grail serum. What makes this HA Intensifier w multi glycan able to go this extra mile is that it contains glycans in addition to the hyaluronic acid that increases the skins moisture. Now I have seen fine lines diminish significantly around my eyes and forehead in a matter of a couple of weeks of once a day ...

What makes this HA Intensifier w multi glycan able to go this extra mile is that it contains glycans in addition to the hyaluronic acid that increases the skins moisture. Now I have seen fine lines diminish significantly around my eyes and forehead in a matter of a couple of weeks of once a day use. This is no small feat when you have an aging combination complexion! My skin now not only looks dewy soft due to the hydration but now it actually looks much smoother as my fine lines look like I had just had Botox injections. That is one of the unique features that makes me look forward to the next couple of weeks as this change in dynamic lines has never been anything I have seen before. The product is meant to complement fillers but I think the results on it's own are magnificent. The serum is extremely lightweight and easy to smooth over my face and it absorbs almost immediately. There is no heavy or greasy feeling around my oilier T zone. It's easy to layer with my other skincare products as it leaves no residue. The bottle should last a number of months as I only use a few drops because of its superior potency. Highly recommend for anyone looking for anti aging benefits in addition to some serious moisture.

The serum absorbs quickly, which I really appreciate, and doesn't leave a sticky feeling, which I've found in other serums I have tried.I have found it only takes about 3 drops of serum to cover my entire face and neck (the directions suggests 4-6 drops), which will definitely make the product last a long time.I'm not sure about the scent. It's not strong, but it's a bit "off", maybe slightly chemically, and even after several minutes, I can still smell it.I say this serum hasn't worked for me yet, because I've only been using it for 12 days (the advertised time for full benefit is 12 weeks).I will continue using this serum, in conjunction with moisturizers and sunscreen, in hopes that I'll soon see fully advertised results.As it's only been 12 days and I've not seen results to date, I cannot say I would recommend this product at this time.
I received this Skinceuticals HA Intensifier for free in exchange for my honest review. I have been using it for the last week and have been very impressed by the results I have seen so far. My skin looks and feels more hydrated and firm with a visible increase in plumpness and elasticity. My fine lines and wrinkles are more filled and less noticeable.

My mature dry skin has been loving everything about this product.Hyaluronic Acids are hit or miss on my skin in my High Desert home. Since there is no moisture in the air to pull all that moisture from, it can start pulling water from your skin instead. This serum worked like a dream as long as I applied it on damp skin, sprayed toner on top of it and then put a moisturizer on top to seal it in. It's always a process to start a new product and find out how it's going to perform. This is one of the best hyaluronic acid products I have ever used.As usual, SkinCeuticals has made an excellent product filled with stellar ingredients. Their Research and Development Department leads the way with cutting edge new products. I have seen visible differences in my skin the last week and I cannot wait to see what my skin looks like in a month or two.I would highly recommend this to anyone with dry or mature skin. It's a potent but gentle mixture that gives immediate visible improvements in your skin's appearance. It has become one of my favorite skin care products and it has earned a permanent place in my skincare routine.
I received SkinCeuticals HA Intensifier Multi-Glycan for free in exchange for writing this honest review. I was eager to try this skin product as it says it's a volumizing serum to plump and contour your skin. As a woman in my 50's, my skin's elasticity and firmness are becoming less pronounced and I want to take care of it as best I can. The first thing I did was open the bottle to smell it since I love fragrance in my skin products. It smelled a bit antiseptic and although I didn't love the scent, it made me think of a high-grade pharmaceutical product, which felt promising. I've dealt with sensitive facial skin issues throughout my life (specifically red blotchiness) and was hopeful this would not aggravate my skin. Unfortunately, that was not the case. Per the ...

The first thing I did was open the bottle to smell it since I love fragrance in my skin products. It smelled a bit antiseptic and although I didn't love the scent, it made me think of a high-grade pharmaceutical product, which felt promising. I've dealt with sensitive facial skin issues throughout my life (specifically red blotchiness) and was hopeful this would not aggravate my skin. Unfortunately, that was not the case. Per the instructions, I shook it well and used 4-6 drops both in the morning and evening before moisturizing. The directions said it should be used with a SkinCeuticals moisturiuzer, but I don't have that so I used it with my own moisturizer. Within 2 days, an area on my face that had been under control was irritated and became red and blotchy. It was only a small area, but it's specifically the spot that gets irritated if a product isn't right for me. I stopped using it immediately once I noticed the irritation. Within 3 days of going back to my usual regimen, the blotchiness mostly resolved itself. The first picture shows where my skin became irritated after 2 days of using the product and the 2nd picture shows how it resolved itself after 3 days once I stopped using the product and went back to my usual skin products I would recommend this product to people who haven't dealt with sensitive skin but not to anyone with sensitive skin.
I used this product once nightly, as directed (4-6 drops), for seven consecutive days before writing this review.Each night, I prepped my skin with Tatcha's The Essence, waited a couple of minutes, and then applied 4-6 drops of the HA Intensifier to my face—2 on my forehead, 1 on each cheek below my eyes, 1 on my nose, and sometimes 1-2 extra on my cheeks if my skin was feeling particularly dry.I've used SkinCeuticals products before and wasn't impressed, but I'm a loyal SkinMedica (Allergan/AbbVie) fan and thus a regular user of medical-grade skincare. Prior to this trying this product, I was using SkinMedica's HA5 Hydrator, but I swapped it out for SkinCeuticals HA Intensifier for the seven day trial period.My skin was extremely dry before I started using ...

Prior to this trying this product, I was using SkinMedica's HA5 Hydrator, but I swapped it out for SkinCeuticals HA Intensifier for the seven day trial period.My skin was extremely dry before I started using this product and I even had some eczema patches on my face. Within just a few days of incorporating the HA Intensifier into my routine, my eczema nearly disappeared, and my skin felt significantly more supple. I no longer had any dry patches at all (which seriously messes up my foundation application).Given that this was the only change in my routine (not just my skincare routine), I'm confident in attributing this improvement in my skin to the HA Intensifier.I've continued using it nightly, and if it keeps my skin this hydrated through the fast approaching fall and winter months, I'll definitely be purchasing it again. Highly recommend!!
