This is a great product and with other products will permanently change your skin
I just ordered this here because of the price. I've used this product before and really like it. If you want to reduce the appearance of lines and wrinkles, this will do it. It hydrates the top layers of your skin and plumps them up so your lines get smoothed out. Works brilliantly for that. It does dry your skin if you use too much, so go easy with it. I also had skin irritation when I used too much, slight burning and redness. But with the right moisturizer, this isn't a problem. I also want permanent change in my skin, so I have experimented with a whole lot of products and now have a great, affordable anti-aging skin care regimen. First, I beg to differ with the other commenters here that you can't reduce lines and wrinkles. Yes you can. It's more difficult if you are addicted to sun or cigarettes - they are the worst for your skin (alcohol isn't great either), but I had deep crevices on my forehead, heavy lines around my eyes and lips and they are gone. Not anymore. In addition to this product (this is the best hyaluronic acid product), I made a daily ritual of a retinol cream at night - best results were from RoC Retinol Correxion Deep Wrinkle Night Cream, 1 Ounce - this product in the morning, and morning and night I use my all time, never live without, the one thing I would pack for a desert island, Bel Essence All-Natural Anti-Wrinkle Treatment - Intensive Anti Aging, Facial Lift Skin Care Formula - 1.5oz . The retinol helps your skin turn over faster so that helps eliminates lines and wrinkles. The hyaluronic acid plumps up your skin so they aren't as noticeable, and the bel essence gives your skin the vitamins, fatty acids, omega 3's and 6's that are needed to build healthy new skin, minus the lines, wrinkles and dark spots. The bel essence also relieves the harshness of using retinol and hyaluronic acid, especially if you have dry to sensitive skin like me. I was shocked that an all natural product could erase wrinkles, but the bel essence is fabulous and even when I stop using the Roc for a while, the bel essence keeps working on the lines and dark spots. Only product I have ever used that gave consistent and permanent results. Add weekly exfoliating (I use a clay mask), and my skin is now, after a year, so smooth, soft, and skin tone is so great, that the only make up I wear is blush and mascara. I started seeing some instant results, the bel essence and hyaluronic acid hydrated my skin immediately and made it look good, but after a couple of months, I was seeing permanent change. I use the same regimen on my neck and hands, and I get compliments all the time about how young I look, how soft my skin is and that I have a glow to my skin. The lines on my neck are gone, and my hands don't look like old lady crepe skin. I look better than I did 10 years ago. The right combination of products makes all the difference.

Lightweight and high quality moisture
I have very acne prone skin but still need a moisturizer. This is my go-to to find balance on a daily basis. It’s lightweight with no added ingredients and gives my skin a beautiful moisturized glow. For the price, it’s excellent quality and quantity. I’ve purchased many times.

Satisfied repeat customer with sensitive skin
tbh, when I decided it was time to start looking for products for a better face-care regimen, I wasn't enthusiastic. I'm allergic to many ingredients used in skin and hair care products, and past experience has shown it requires months of research for me to find a product that's clean enough for my needs. That's the main reason I decided to look for products that contain the main, essential ingredients I was looking for, like HLA. When I found this product only had 3 ingredients, Distilled Water, Hyaluronic Acid, and Benzylalcohol-DHA, I decided to give it a tentative try. I was relieved when I tested it every other day for the first week and didn't react to it, even more relieved when I used it 4 consecutive days the 2nd week without a reaction! This has become the main ingredient in my face care routine! It's thin, lightweight, spreads quickly and easily, and absorbs within a minute by itself. It also mixes with other skin care serums and lotions well, so it's easy to customize my skin care regimen to my needs. I appreciate that it doesn't block pores, so my skin can sweat as it needs to without my ending up with "stuff" running into my eyes. Since adding this to my skin care regimen, I've noticed better texture, more plumpness, and more even tone. I've also noticed how those facial features worsen if I get in a rush and don't use this product for a few days during the week... 0.0 I'll definitely keep purchasing as long as the product's ingredients don't change!

Great product
I really like this product. I see great results and improvements with my skin when I use it regularly. For the price it is an absolute STEAL. If you're on the fence about giving it a shot you should definitely give it a try. I've had a 1 oz bottle for 3 months and barely made a dent in it. I reordered simply so I could leave one at work where I often have to stay overnight. A 1oz bottle could likely last me upwards of 9 months or more, which is absolutely astounding for the price. Pennies a day to achieve what shelves worth of expensive products never really did. My only issue with it is that I really hate the dropper bottle. I'd much prefer the cap that allows you to just push down to dispense product, but you have to buy a really huge bottle to get that option. I believe it's only the 4 oz bottle that comes with it. That would be almost 4 years (or more) of product at my current usage, and not only would I not keep the same opened bottle that long, it would be too large to fit conveniently in my bathroom vanity. The dropper is really inconvenient, and I'm always afraid I'm going to knock over the bottle while I have the top off. You have to take the top off, apply the product to your hand, and then you're left to decide if you want to try to put the top back on one handed while the product drips off your hand and ends up wasted on the counter, or if you just set the dropper back into the bottle and finish applying the product to your face, hoping that you don't forget to go back and screw it back on when you're finished with the routine. It would be awesome if they offered the 1 or 2 oz bottle with the pump top rather than that dropper. I would have no complaints at all then!

but look like they're in their 30s and 40s
I'm in my late 20s and I want to delay wrinkles and other signs of aging before they show up. I've researched a lot and found out that delaying the signs of aging and preventing them is the way to go to stay "youthful" as long as possible. And in fact, people should start taking care of their skin in their 20s because it's easier to keep a smooth, wrinkle free skin rather than trying to erase or hide wrinkles and other imperfections. I started using this product about two months or so ago when I saw lines around my eyes and on my forehead. I see a lot of my peers who are still in their 20s, but look like they're in their 30s and 40s. They look tired and have lines all over their faces that weren't there before. First off, I've tried to consciously stay out of the sun if I could help it. I use sunblock if I can't avoid the sun. My peers didn't really care for that when we were younger and the sun damage on their skin is obvious. Their skin looks dry, cracked, tan but old. I say this because if you want the best benefit from using this product, you should try to stay out of the sun and use sunblock if you can't. Also, this product works really well with a moisturizer. I apply this product first on clean skin and let it dry for a minute. Then I apply Neutrogena Rapid Wrinkle Repair for Night because it's a moisturizer and also has retinol, which really helps with skin repair (wrinkles and uneven tone), smooths skin by promoting new growth, and also helps keeps my skin clear from acne. Once a week, I do a 1 minute glycolic peel (30%) then rinse off and apply hylauronic acid and just a simple moisturizer on top. I skip retinol products that night because it will burn/sting the newly treated skin. Also skip anything that would sting if you are somehow still using any other products like salicylic acid, etc. The glycolic peel makes a huge difference. I could tell the first time I used it that my skin was softer, smoother, more even toned, and just feels better. Read up about it for sure before using it because it can be strong. It's supposed to help peel away dead skin and stimulate new smooth skin. It seems to do that for me. But these products I'm talking about like retinol and glycolic peel will make your skin sensitive to the sun and will easily make you burn. So, definitely stay out of the sun if you can help it, use sunblock, a hat, and whatever else you can do to avoid sun exposure. Otherwise, your skin won't look great and it will all be for nothing. But if you take care of your skin consistently and follow directions well, you will see a big difference. It's like exercise. You have to do it everyday, but you won't see a big difference until after some time. I wish I took pictures of my skin before I started my regimen. I'd really love to show what has changed for me. Also, I recently got married and was showing people my wedding photos. A lot of people assumed I was the "baby" in my family. Just looking at photos, they thought I was the youngest out of all my sisters (also my bridesmaids). I am 7 years older than one of my sisters and 10 years older than the youngest. People were blown away and actually felt bad for my sisters. And I can still hang out with my siblings and their friends if I need to. Their friends also mistake me as someone closer to their age and wouldn't believe I'm much older than they are.

Works good. No back info on back of bottle
What’s inside the bottle works well. I’ve used hyaluronic acid before. HOWever, my issues are with the labeling and the mode of dispensation. This item shows users applying the product with a dropper in the photos of the item. Not so. This is truly a pump spray so there is no dropper. Pumping is tricky. It recently squirted me straight in the eye. I would have preferred a dropper. The back of the bottle where need-to-know information usually is, is just plain white with no info on it. Like safety info, how to use product, ingredients, potential side effects, and the like. See photos. This product is not oily. It dries quickly. It provides some moisturizing on my face. My Skin drinks it in. It leaves my face and neck areas feeling smooth to the touch. I have not experienced any skin irritation with this product.

Great Hydrator!!
I am a 17 year old girl and I believe that anyone at any age can use this. I've never really had a problem with dry skin up until recently. I've been using the Neutrogena Grapefruit face wash for more than 3 or so years and it has always helped to keep my skin clear and control my mild acne. However, as of lately my skin has been very prone to drying out, especially now in the winter, and my moisturizers haven't been doing an exceedingly well job at KEEPING my skin moisturized and going on smoothly. But with this Hyaluronic Serum, my skin has not been dry or looking flaky at all in the last few days that I have been using it. I love the fact that this is an acid that your skin produces, so in other words it is completely risk-free to use on your skin as it isn't some man-made chemical but something that your skin already produces. This stuff is also paraben-free which I love. There is nothing in the bottle but hyaluronic acid and it works wonders. It feels slimy at first when you put it on but trust me, it absorbs wonderfully! It doesn't just make the skin on my face soft, but SUPPLE from intense hydration. And since it's not an oil or oil-based, it will give you such even hydration, and areas that may get oilier than others will be balanced while the dry areas get the hydration that they need. I love this stuff. I use two drops on my face right after i wash my face (or after I use my dermaroller at night), then i combine one to two drops with my moisturizers all at once in my hand and it helps the moisturizers to absorb so much better instead of just sitting on my face and making it feel heavy in a way. I would recommend this to anyone who has dry skin issues or just wants to maintain proper hydration of the skin. It's perfect and I love it. I also found that post-acne marks that I have had from a few months ago are starting to fade slightly, and I believe that is due to the skin getting enough hydration, so the marks seem less noticeable compared to the dark purple they turn when my skin in that area is dried out. Overall I am very happy with this product. It got to me very quickly and I will definitely continue to purchase this product.
