Skinceuticals have re-formulated their cult hyaluronic acid serum (now called SkinCeuticals H.A Intensifier Multi Glycan) and we need to talk about it, because if you’re after a serum designed to take hydration to the next level then this might be for you.
Plus, if you loved the old SkinCeuticals hyaluronic acid formula, you will definitely love the new and improved product as it’s just an upgraded version.
It's still your beloved cult classic, but made slightly better...

What Is the Skinceuticals Hyaluronic Acid Intensifier Multi-Glycan?

It has increased potency, with new ingredients and now it doesn’t just hydrate, but it also helps to plump and firm the skin better than before.
So whether you’re dealing with fine lines, dryness, dehydration, sensitivity or just want to amplify your glow, this reformulated serum is like the ultimate hydration hero for every skin type.
Main features:
  • Boosts hydration for 24 hours: Increases skin’s HA content by 30%, locking in moisture and enhancing plumpness.
  • Minimises fine lines and sagging: Reduces the appearance of fine lines and supports improved skin elasticity and firmness.
  • Enhances skin radiance and texture: Promotes a smoother, more luminous complexion.
  • Strengthens facial contours: Visibly refines and renews facial structure for a more youthful appearance.
  • Gentle on skin: Free from parabens, fragrance, and dyes, making it ideal for all skin types, including sensitive skin.
Interested? Let’s dive into what makes this next-gen formula different. 

Key Differences:

What's the difference between the old SkinCeuticals hyaluronic acid formula and this new SkinCeuticals hyaluronic acid?
Firstly, if you have tried the original formula, this one does feel slightly different. Less sticky, a little lighter, but with just as much, (or dare I say even more?) hydration than before. 
However, the main updates to this new serum are these ingredients below:
  • Proxylane™: The concentration has been increased from 10% to 12% in the updated formula, meaning it can offer enhanced support for skin firmness.
  • Purple Rice Extract: This ingredient has been replaced by Lactobacillus/Soybean Ferment Extract in the new formula which helps to soothe the skin and support the microbiome. 
  • Lactobacillus/Soybean Ferment Extract (2.0%): this ingredient has been updated  in the new formula as a post-biotic ferment to increase glycosaminoglycans, which are essential for maintaining skin moisture.

Is Skinceuticals Hyaluronic Acid Intensifier Multi-Glycan Good for All Skin Types?

What skin types can this serum benefit?
The age old question that pops up in clinic time and time again, do you need a hydrating serum in your routine
Well, maybe, but not always.
Here’s the thing: a hyaluronic acid serum benefits anyone looking to boost skin hydration, plump fine lines, and improve overall skin texture, but this means it’s going to be most beneficial for dry, dehydrated and ageing skin.
And while oily and acne-prone skin types can also benefit it is not a must for these types of skins.
However, if you  are sensitive you will love this serum for its soothing and plumping effects. 

My review of SkinCeuticals H.A Intensifier Multi Glycan:

I personally think this updated formula is much more elegant and soothing than the previous version, which on my combination skin, did tend to feel a lot thicker.
And while a hydrating serum is not a mainstay in my everyday routine, it is a product I love to rotate into my routine through the cooler months (which are coming!) alongside post clinical treatments to help give back to my skin after a laser or a peel.
Which means, this is a product that ticks all the boxes if your barrier is impaired/sensitised or needs a little extra hydration.
As a dermal clinician I love reminding people to listen to their skin, when thinking about introducing new products.
However, the new Skinceuticals hyaluronic acid formula is not a product that should be hard to integrate into any routine, it works with all ingredients and if glowy, plumpy skin is your goal then your skin might just have met its match with Skinceuticals reformulated HA Intensifier.

Skinceuticals H.A Intensifier Multi Glycan Reviews From AB Staffers:

"I’ve had a hot summer sponsored by beach trips and chilled reds, so, naturally I’ve sprouted some dehydration lines (sign of a life well-lived).
I’m going to level with you – when I got the chance to try this serum, I didn’t want to like it. It’s more money than I’d usually spend on a hyaluronic acid and I was praying it was overhyped and would do a similar job to my regular hyaluronic acid.
Unfortunately, it knocked it out of the park. My skin has forgiven me for months of sea water submerges and emerged reborn.
It’s bouncy, it’s fresh, it’s glowing and my dehydration lines have retreated.
Big standing ovation for whatever a multi-glycan is, my skin thanks you." - Felicity, Copywriter.

"For someone with incrediblly thirsty skin, it's a necessity that I have a hydrating serum in my skincare rotation.
hen the new SkinCeuticals H.A Intensifier Multi Glycan Serum came across my desk, I was beyond excited to try it!
This serum is glorious. After using this for a few days, my skin felt more plump and bouncier.
The dehydration lines I had been noticing on forehead and above my cheekbones were improving and my makeup was sitting so much nicer on my skin." - Elle, Assistant Trade Marketing Manager.
