'The only one I’ve found that actually makes a difference.' 14 women review *that* trending hyaluronic acid serum.

Unless you haven't been on the internet, you've likely caught wind that hyaluronic acid has become the most talked about ingredient among beauty creators and skincare TikTok right now. 

It's the superstar ingredient that prevents dry and parched skin, as it's a powerful humectant – meaning it attracts and retains moisture like a sponge. It's slinking around with quite the resume too: it can hold up to 1,000 times its weight in water (!!), is helpful for all skin types, and plays nicely with any other actives you have in your routine.

You'll be tickled to know hyaluronic acid is actually a molecule naturally found already in our skin and body's connective tissue. Though at 25, our body stops producing as much of its own supply (I know, rough news). But thankfully there are topical ways we can introduce more hydration, for the appearance of plumper, more dewy skin.

Like this new cutie, Garnier's Skin Active Hyaluronic Aloe Hydrating Serum.

At $35 a bottle, it's the brand's first serum concentrated with 3 per cent hyaluronic acid, aloe vera and glycerin, and promises long-lasting hydration with visibly re-plumped, bouncier skin after the first use. 

It's having a real moment online, and has been proven to hydrate skin up to 10 layers deep (the upper layers of epidermis/stratum corneum, for beauty nerds playing at home). Designed to suit all skin tones and types, it's also dermatologically and ophthalmologically tested (we love to hear it).

Soooo, how do we know if it actually delivers, and deserves a permanent spot on our skincare shelves?

We had 150 women on Mamamia's You Beauty Panel to roadtest it for us over the course of a month, and report back with their findings.

Turns out 80.5 per cent rated the serum so much, they said they'd repurchase it – and 30 Panellists said it was the best hyaluronic acid serum they've ever used. Okay, we're INTRIGUED.

Here's some of their honest opinions.

Kristie, TAS: "The only one I’ve found that ACTUALLY makes a difference."

"10/10. My skin is as plump as a newborn baby's rump! Dewy fresh and soft as butter. Out of all the hyaluronic acid serums I’ve tried, this is the only one I’ve found that ACTUALLY makes a difference!"

Taryn, NSW: "The best hyaluronic acid serum I have ever used."

"Great overall experience! I was very surprised with how my skin responded. My skin feels so much more hydrated and plump. The best hyaluronic acid serum I have ever used."

"Would rate it a 4/5! This serum is super hydrating and made my face feel smooth and plump."

Clare, NSW: "Layers well with my other serums and moisturiser."

"Good experience overall! My skin definitely looks and feels more hydrated after using the serum. It has a nice refreshing smell too, and layers well with my other serums and moisturiser. Would recommend and repurchase!"

Penny, 44: "The fine lines under my eyes and face weren’t as noticeable."

"By the end of the trial, the fine lines under my eyes and face weren’t as noticeable as my face was more plump and hydrated. I'd recommend this serum to loved ones, and would purchase it again!"

Natasha, QLD: "I LOVE this product."

"I LOVE this product. It is nice and thick (but not too thick), meaning it is easy to apply to the face and doesn’t leave a residual sticky feeling. It left my face feeling hydrated and plump."

Krystina, NSW: "My face feels much more supple and hydrated."

"I have been using the serum morning and night for the past month, and can say that I have quite enjoyed using it. There is no offensive scent, the consistency is nice, and it absorbs well. As someone with sensitive skin, I didn't have any reactions which was nice! My face feels much more supple and hydrated, especially in my T-zone that has always been a dry area of concern for me."

Maria, NSW: "Nice to have a serum that I didn’t react to any ingredients."

"It was easy to add into the routine, smelled great and felt soft on the skin. It’s refreshing and as someone who has sensitive skin, it was nice to have a serum that I didn’t react to any ingredients."

Justine, VIC: "Makes my skin feel really soft and hydrated."

"This serum felt really lovely on my skin. It smells fresh and makes my skin feel really soft and hydrated."

Chloe, NSW: "A great product that actually works!"

"A great product that actually works! I have spent big on serums in the past with little to no results. This product is extremely lightweight, glides on easily and dries dry (no sticky aftermath). Not to mention, it smells divine! The only thing I can fault is the dropper as I found it hard to squeeze it enough to fill the dropper in one go. I honestly felt my complexion became a lot brighter overall, which is amazing as I'm averaging 4 hours broken sleep a night with two young babies!"

Alicia M, NSW: "It has absolutely found it's way into my daily routine."

"I really enjoyed using this hyaluronic acid serum, and it has absolutely found it's way into my daily routine. Not only did my skin look and feel hydrated, but my texture felt and looked much smoother. I often have very small red bumps on my cheeks that simply aren't there when using this regularly. No irritations, no nasty smells and a thick, juicy texture."

Abbey, NSW: "I experienced great results within 12 hours."

"I really enjoyed using the serum. I experienced great results within 12 hours of using it (skin felt and looked more hydrated). It gave me lots of motivation to continue implementing it in my daily skincare routine."

Katrina, QLD: "I started to see a difference in days."

"Loved it!!! What a difference; my skin feels so much more hydrated! I was sceptical at first, but I started to see a difference in days. It was gentle on my super sensitive skin and a little goes a long way. I wish I would have taken more pics! Definitely recommend!"

Ally, QLD: "A staple in my everyday rotation."

"The product was great! It soaked into the skin seamlessly and worked well with all my other products. It has a light, fresh scent from the aloe which I love. The texture is thick enough to not slide off your face upon application. Overall, my experience was great, and it’s a staple in my everyday rotation."
