  • Amplifies skin’s hyaluronic acid levels by 30%
  • Reduces the look of crow’s feet, nasolabial folds (parenthesis around the mouth or laugh lines), and marionette lines (lines from the corners of the mouth down to chin) for smoother, firmer skin
  • Delivers long lasting hydration to visibly improve skin’s texture
  • Unique serum-gel texture format creates a smooth canvas on skin
  • Paraben- and dye-free, ideal for all skin types

    See Protocol

    Protocol: Average results shown. A 12-week, single-center, clinical study was conducted on 59 females, ages 42-60, with mild to moderate facial sagging and loss of firmness, rough skin texture, nasolabial fold wrinkles, marionette lines, and presence of fine lines/wrinkles in the crow’s feet area. H.A. Intensifier was used twice daily in conjunction with SkinCeuticals Gentle Cleanser and a sunscreen. Efficacy and tolerability evaluations were conducted at baseline and at weeks 4, 8, and 12.

  • Science & Proof


  • Science

    Hyaluronic acid naturally occurs in the skin and plays an important role in maintaining moisture. This essential molecule however has a short lifecycle in skin, with 30%-50% degrading every 24 hours. With age, the skin’s ability to produce hyaluronic acid decreases. Production starts to decline in the 20s and this decline accelerates in the 40s. Decreased production rapid degradation of hyaluronic acid contribute to signs of aging, including decreased firmness, less facial plumpness, and rough texture.

    While hyaluronic acid is a powerful hydrator, the size of the hyaluronic acid molecules are too large for optimal skin absorption. H.A. Intensifier uniquely combines surface-hydrating hyaluronic acid with 10% proxylane™ and an optimal concentration of licorice and purple rice extracts to support skin’s hyaluronic acid levels.

Key Ingredients

  • 10% Proxylane™
  • 2.0% Licorice Root Extract (dipotassium glycyrrhizate) + 0.2% Purple Rice Extract
  • 1.3% Hyaluronic Acid

Supports skin’s hyaluronic acid levels to help improve the appearance of skin firmness.

Rated 5 out of 5 by from Skin feels so much better I have tried different samples and it always made my face feel so much better and moisturized.

Rated 5 out of 5 by from Happy go Lucky with this product I have added another SkinCeutical to my daily facial routine. I am happy with the results I am getting. Now I have the Vitamin C, H.A. Intensifier, A.G.E. Interrupter, all products are delivering results. Thanks to my skin care providers.

Rated 1 out of 5 by from Has Done Nothing I've had both good and bad experiences with Skinceuticals products. I normally use the hydrating B gel for my super-dry hyperpigmented skin and it's always worked well for me so thought I'd give this a shot since it's labeled an "intensifier". I've used it just about everyday for the past month and have seen absolutely no difference. I wouldn't recommend this product even if it were cheaper because it hasn't made a difference to my skin, and the bottle is almost empty after a month or so of use.

Rated 5 out of 5 by from My face loves it! I received a sample of this product and I absolutely love it. I read the descriptions and instructions but needed to try to for myself. I started using it about 4 or so days ago and already see an improvement.I need to order this once the sample is gone.

Rated 5 out of 5 by from Great Moisturizer I noticed a difference with one day of use. It absorbs well and doesn’t sit on the skin. My skin was smoother and felt calmer - normally I have dry skin, it gets tight and feels dry/flaky. This work well under make-up and with cream moisturizer at night. One bottle lasts about a month, with use twice daily to face, neck, and chest.

Rated 5 out of 5 by from Proven results but not overnight I received my first bottle as a sample and once I ran out I immediately felt the need to purchase. This serum works. I’m not the type to write reviews but I am the type to read reviews before I purchase so I thought it was important to give my feedback on this product. The serum leaves my skin feeling soft and hydrated. Most importantly I saw results within a month or so. And continue to see them. My lines are finer and sun/age spots have diminished. I use this product every night and every morning. Definitely a must to add to your skin care routine.

Rated 5 out of 5 by from more thorough directions needed I bought the HA Intesifier due to the great reviews. I was hoping for more detailed directions in the box. I've recently adopted a lot of SkinCeuticals line. I have the HA Intensifier, the Triple lipid restore 2:4:2, Retexturing Activator and the Sheer Physical UV Defense. What order and how many times a day should I apply these products?

Rated 1 out of 5 by from Alcohol Dent. This is drying. Will be returning.Surprised to see this as in ingredient. I also don't like products which are loosely marketed for all skin types. My feeling is that my dry complexion would use different products from that of someone with an Oily complexion.

Rated 5 out of 5 by from Amazing I have tried lot of high end skincare products. Nothing comes close to this. I want to restock so many bottles! I use this with the CE ferulic and results are amazing!

Rated 5 out of 5 by from facelift in a bottle Skinceuticals really won me over with this Hyaluronic Acid Intensifier. I have very sensitive and dry skin and absolutely love how HA leaves my face feeling so hydrated. I have been using HA for about a month and a half now and while I am impressed with the results I see, I am even more stoked by how many other people have noticed the diminishing laugh lines and crows feet. Once you try this serum, there's no turning back!

Rated 5 out of 5 by from In loveee. This stuff makes my skin so soft and keeos it moisturized all day long no matter what activities I'm doing. Since starting use I've also seen a reduction in my fine lines and I've been more than happy with the results!

Rated 5 out of 5 by from Does a great job! I got a sample of this 3 weeks ago, I've been using it since then. It's dramatically reduced the appearance of my fine lines around my eyes and mouth. Not too greasy, and a little goes a long way...

Rated 5 out of 5 by from The Best Skincare Regimen There is nothing like the SkinCeuticals skin care line. I've only been able to get samples so far, but I've been using them religiously and my skin has improved so much. I highly recommend trying these products and I will be purchasing as soon as I can afford to!

Rated 5 out of 5 by from Actually works! I have heard the praises of using various hyaluronic acid products for a couple of years now. This is the third prestige product I have tried, but it is the first one that ACTUALLY WORKS! I highly recommend it.

Rated 5 out of 5 by from Extraordinary Product I have been using Skin Ceutical products for years. C&E Ferulic is phenomenal. I started using the HA Intensifier about a year ago and it is an amazing product. I saw immediate results. I apply after my C&E and I cannot believe the results. My skin is so hydrated and plump. I am 75 years old and acquaintenances stop me all the time to ask me what Imuse on my skin. The answer is simple; my Skin Ceutical regimen. There is nothing on the market to surpass these products. HA is a must have!

Rated 5 out of 5 by from You get what you pay for Hesitate no longer and add this perfect product to your cart! I am a huge skin care lady and have tried a few different hyaluronic acids, and this one beats them all! It leaves your skin feeling soft and smooth. I bought this product for my dehydrated skin, and boy does it work. I know it's a pretty penny, but so worth the investment. I use mine every night and it lasts about six months. Defiantly recommend!
Date published: 2020-04-06
Rated 5 out of 5 by from awesome It really works well if you use in combination of the other skin care products. It's an investment of your skin and well worth it.
Date published: 2020-03-22
Rated 1 out of 5 by from No change in my skin I see no change whatsoever in my skin. I bought the whole Skinceuticals line and in my opinion, it's not worth the money. Sorry to say this. I was very excited about the products but sadly see no difference in my skin after several weeks of religious use, so I will not purchase again.

Rated 5 out of 5 by from Great product I got a sample in the mail and love it! I see a difference already even though I only used it a short time. It's kind of pricey so I'll have to wait to get it.
