I started using this earlier in the year as a step up from B5 gel.  This is much thicker and luxurious feeling.  You do not need to use much.

Love this serum! Leaves my skin feeling hydrated and I've noticed a wonderful change in firmness and texture of my skin. Highly recommend!

So, at first this product felt great and seemed to ease my reactive skin post Tretinoin, buuuut after a couple weeks of regular use my skin got super itchy and dry and I cut down my tret use assuming it was the cause. After looking at the ingredients, and I’m not sure how I missed this as I ALwAYS look at the list, alcohol denat (basically rubbing alcohol)is 3rd in the queue! Not cool for sensitive skin. My guess is after regular use it weakened my skin barrier. Getting better now that I’ve quit using the intensifier. 

I love this HA so much immediately plumps my skin once I add moisturizer to it. I also feel this helped my texture no lie. I never write reviews y'all but this is worth the buy I swear it!!  You have to use a moisturizer with it or it defeats the purpose haha please read on what HA does and you will understand why I said that. Good luck on your skincare journey 

Best hyaluronic acid out there. I love skin ceuticals and I am a daily user of all the products available to me.

This is not something I use every day but it's a fantastic product. I'm here to purchase another bottle. I use it 1-2 times a week as needed or if I've done another treatment (like a detox mask) that may be drying. This works great and it's more effective for me than other brands I've tried. A little goes a long way. Personally, it works best if I've primed my skin first. I use another brand's glycolic essence toner on my skin every AM / PM to soften it some before I apply all my products. Then when it's just about dry but still slightly moist on my skin, I apply a small amount of this HA serum all over my face and neck. It's easier to glide on with slightly moist skin. Then I gently PAT it into my skin until it's absorbed. I follow up with another brand's Beauty Elixir hydration spray, which I use daily. I then PAT that into my skin. Then follow up with my moisturizer. It's incredible how well this works to hydrate my skin. I think some people forget that HA serums need moisture to work and expand the moisture. It also works best if your skin is regularly exfoliated via scrubs and products that slough off dead skin cells. This way the HA serum (or any product) can absorb better.

This product is so helpful for extra hydration. I definitely see a difference in fine lines after using it as well.

Love this product! Noticed visible results within 2 months. I only use this product at night, but skin has been more smooth and plump!

My dermatologist recommended this and I can see why. It’s amazing. I absolutely love how plump and smooth it makes my skin. I use Tretinoin and this plus the triple lipid repair keep my skin from drying out. 

So much I love about this product. My skin is soft, hydrated, smooth, and bouncy. This is only my second bottle. For reference: I have sensitive skin, and had no adverse reaction. My SkinCeuticals morning routine is as follows:  First, I cleanse alternating with Glycolic Renewal Cleanser Gel, and twice a week with Micro Exfoliating Scrub, next I tone with REN Daily Steady Glow AHA Lotion Tonique , I then apply CE Ferulic, follow with this amazing HA intensifier, next B5 gel, AGE Eye Complex, then Triple Lipid Restore, and last SPF 50 Physical Fusion UV Defense Sunscreen. I am complimented all the time on how great my skin looks!  Evening Routine: Apply cleanser to my PMD tool and massage face for 3-5min, really getting all makeup off, next I apply Resveratrol BE, B5 gel, followed by Triple Lipid Restore moisturizer. You can add in the Neck repair at this time as well. Don’t forget your lips! I use Laneige Lip Sleeping Mask.  Lastly, I sleep on my SLIP pure silk pillowcase because I sure don’t want all my time and money spent on these fine products sinking into a cotton pillowcase!  Note: Twice a month (2-3days a week alternating days) I add in Retinol 1.0 in the evening. This stuff is strong and it will tighten, and make you feel a little dry, and peel slightly. Use generously your moisturizing products mentioned above, and it really helps! But the results are no joke, AMAZING! If you don’t use Retinol, maybe try working your way up to this strength. But for me, I want the maximum benefits straight away!  The very last thing I’ll mention is that I keep all my skin products except for the sunscreen in the fridge. Again, I want to help keep these expensive products fresh, and I find the cooling effect feels great on my skin.  Hope this review was helpful. I try my best to give details, bc I know I look at reviews before a purchase.
