Hydro Boost Hyaluronic Acid Serum - with Pro-Vitamin B5 & Glycerin, Instantly Replenishes & Smooths Dry Skin with 24-Hour Weightless Hydration, 1 fl. oz.

I was doubtful that this serum would improve my 78 year old wrinkles, but I am really pleased that they definitely are getting less noticeable after a few weeks. Serum is gentle on the skin, no strong scent ( which I hate on facial products,) is not oily, and works really well under the moisturizer.

Nice serum. It’s basic, but it gets the job done for the price. It’s not greasy, absorbs quickly, and is fragrance-free

I wish I had taken a picture of my face 3 months ago because this line of products has taken about 10 years off my face. I use it twice a day, AM & PM and I’ve been dedicated to it rarely missing a day. Before I started using this I had gone to an aesthetician to have the deep lines on both sides of my face filled in. He told me they were too deep to fill. After 3 full months of using neutrogena products those lines are GONE. My cheeks line are so much softer and the lines are hard to see. I could write a book on how much younger my face looks. The skin on my face glows now from how good both day & night moisturizers are. I’m a few years away from 70 and haven’t felt this confident about my face since hitting 55 yrs. I use 4 of their products religiously. First I use Tru-skin vitamin C then I use this moisture boost serum after than I use their regional and finish up with day or night moisturizer. I’ve received many questions about how I look such as, “You look rested” or “what have you done bc you look different”. I just say thank you and hold my secrets. But I can tell you all that this line of products really worked on me. If your considering this line, stick with it everyday and take a before pic of your face so you can see the difference. 5 stars!

I'm happy with this product! I originally bought it to replace a more expensive serum I had that served a similar purpose. This product gives similar results, which is to hydrate my skin's dry zones before putting on moisturizer. My skin retained it's "plump" feeling while I used this product, so to me, it's doing what I want and at a more affordable price! I only wish there was a little more product and that it was easier to suction out when it gets low.

First time using this product...but I've added it to my routine. I love the extra hydration without any extra product build up it works and works well with the neutrogena face care regimen. Love the care and glowing skin.

I usually purchase this from Walmart but they were out locally and I needed a refill like yesterday. Hydrates skin without the sticky residue. Great for the price. A staple in my skincare routine.

I used this for around 3-4 months and my skin was super moisturized and bouncy, just like the commercials. However, at one point I noticed I had this awful dry patch next to my mouth, and my lips started getting really dry and chapped. NOTHING made them better. It was summer and humid--not windy and dry and cold--so I really had no idea what was going on. I eliminated a ton of things in my "routine", but didn't figure this could be it because it's FRAGRANCE FREE (which is so important; fragrances don't need to be in ANY skincare products and I'm super mad that they're always there). However when I eliminated this, the problem didn't get better, but it didn't get worse. I changed brands, treated the dryness VERY slowly and it eventually went away. Fast forward months later, and I ran out of my other stuff so I grabbed this again. Within hours my lips started burning and drying out. I have no idea what ingredient in here does this to me, only that something does. No other brand of HA does this to me (that I've tried). Bummer, because it did work on my skin before it irritated it but at some point it turned and started bothering it. I have pale, dry, sensitive skin that's easily irritated. If you have easily irritated skin, use with caution. The moment you notice any dryness, discontinue use. As with any skin care product, results are based on a person's regimen and skin type, which is why I didn't give it a 1 star. I think it works if you're not irritated with whatever irritant is here, it's a good value and I like the packaging. Hopefully you won't react like I did.

I’ve been using this serum morning and night as the very first step in my skincare routine, and I can honestly say it’s become a non-negotiable for me. The texture is so light and refreshing—almost like water gel—but it somehow delivers deep, lasting hydration that leaves my skin feeling instantly plump and smooth. It absorbs quickly, never feels sticky or heavy, and creates the perfect base for whatever comes next in my routine. Whether I’m layering serums, moisturizer, or makeup, everything just seems to go on better after I apply this. I have combination skin that’s prone to dryness in certain spots, and this keeps everything balanced. No breakouts, no irritation—just consistently happy, hydrated skin. A few things I love: • Lightweight, cooling texture • No greasy residue • Works beautifully under makeup • Helps my skin feel soft and calm all day If you’re looking for a simple but super effective hydration step, this is it. I’ll keep repurchasing again and again.

I usually don’t notice a difference but this stuff seems to really soften the skin

It helps moisturise. And it isn’t messy. It feels good.

Génial, super produit. Je recommande
