Product Details

H.A. Intensifier is a multi-beneficial corrective serum proven to amplify skin’s hyaluronic acid levels. This unique formulation contains a high concentration of pure hyaluronic acid, proxylane™, and botanical extracts of licorice root and purple rice to support skin’s hyaluronic acid levels and deliver surface hydration, helping improve the visible appearance of firmness, smoothness, and facial plumpness.

  • 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
  • Can be used as home care after dermal fillers; always consult with a physician for individual regimen recommendations

    In a 12-week clinical study, H.A. Intensifier significantly improved the appearance of key aging indicators:

    • 23% improvement in plumpness
    • 9% decrease in sagginess
    • 11% improvement in firmness
    • 13% improvement in elasticity
    • 18% improvement in texture

    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 4 out of 5 by from Most hydrating product I have ever tried. After a week use in along with CE ferulic acid, my fine wrinkles barely noticeable. It’s a keeper.

Rated 5 out of 5 by from The Best I have been using after my microneedling and it’s the best ! I am 49 and everyone thinks I am so much younger. My skin is noticeably softer and smoother.

Rated 5 out of 5 by from Delivers a Little Extra Glow I decided to try adding this to my skin care routine a few months ago. My intention wasn't to fix any problem, but I have to say I was delighted that it gives my skin this little extra glow. It just looks a big younger and brighter.

Rated 5 out of 5 by from Moist! After my 1st try on CE Ferulic, I have decided to try other product. I heard people are telling me that hyaluronic acid is a great thing to use on routine basis. Especially because my skin is on the dry side when traveling, I got HA to use at night before my mosturizer. I love it! It gives me dewy look when applied. Next morning, I notice my pores are smaller & very fine lines of mine disappear. I am hooked on another Skinceuticals product.

Rated 3 out of 5 by from Absorbs very slowly I tried this as a sample from Skinceuticals, and was a little disappointed. It felt very sticky to the touch and took a long time to absorb into my face (had to wait about 5 minutes before moisturizing). Once absorbed it was OK, but I much prefer Metacell Renewal B3.

Rated 5 out of 5 by from Great Plumper I swear this serum helps plump up areas around my creases in eye area and helps minimize my wrinkles. I use at night only to save.

Rated 5 out of 5 by from Great product I gave bought this product a few times and I’m very pleased with it. It hydrates my skin, It plumps ur my skin which helps to eliminate fine lines and wrinkles. My skin feel soft and renewed. I’ve tried other brands but I keep coming back to this one because it is the best!

Rated 4 out of 5 by from Something Extra I have been using this product off and on with the vitamin C serum whenever I want to really make my skin look good. I get good results from the C serum alone so I forego spending the extra $100 but there’s nothing like the two together to get your glow on.

Rated 5 out of 5 by from Pam19 I have been using this product for a while now and have seen a real difference in my face. I use it with C E Ferulic, they work great together.

Rated 5 out of 5 by from Love I’ve been using it for about 6 months and love it. It has done wonders for my skin. It has improved the visibility and smoothness of my skin.

Rated 5 out of 5 by from Great results! I have bought several “expensive” skin care products and this by far is one of the best. Tingling feeling when I first put it on, but then felt great! Have noticed that my skin is smoother and younger looking..definitely a must for people who can not tolerate retinoids.

Rated 5 out of 5 by from Beautiful skin I’ve been using this product for about six months. My skin is plump, moisturized, smooth and radiant. I won’t be without this product!

Rated 5 out of 5 by from Excellent product! I absolutely love the hydration! My skin is positively glowing. It’s worth every penny to feel this amazing! Thanks Skinceuticals!

Rated 3 out of 5 by from Causes sunscreen to rub off and pile on skin Love the texture of the product and the feel of it on my skin. The problem I have is when it’s applied under my Skinceuticals sunscreen it causes flaking and piling (sort of the appearance of dead skin flakes). When I use it at night, without sunscreen, there’s no piling. I’m assuming that the two products don’t mix very well. It’s very frustrating because I love the product. Unfortunately, I probably won’t order it again.

Rated 5 out of 5 by from Love this stuff I am on my second bottle of this stuff and love it. I use the C E Ferulic in the morning and wanted something for the evening. I have definitely noticed a difference in my skin since I added it to my regimen.

Rated 5 out of 5 by from I Recommend This Product- Smoother Skin I am very happy with this product. I had a sample and liked so much I purchased the full size. I use twice daily and have noticed a boost in skin hydration and smoothness. It is thick but only need a few drops to cover my face. I use my C Ferulic once very 3 days and use the Intensifier after. Love SkinCerticals!

Rated 5 out of 5 by from It works! I'm a 37 y.o. guy and only started taking care of my skin a few years ago when I started noticing evident signs of aging. I've always been suspicious about skincare products, but my dermatologist recommended H.A. intensifier together with a skincare regimen and I gave it a try. I can confidently say this product works. My skin looks less smoother and younger in general.
Date published: 2019-04-22
Rated 4 out of 5 by from Hydrating Serum I got a sample of the HA Intensifier with a Skinceuticals purchase I made. I'm not sure which product, or if the combination of products, gave me results, but I have seen results in a short amount of time. My face was uncomfortably dry and tight. Since using this product, my skin feels healthy and looks dewy. I also have extremely sensitive skin and will get rashes and hives to certain ingredients, but have had no reaction to Skinceuticals products! This serum is not a liquid like other serums - it has a milky consistency and no smell, which is a plus!
Date published: 2019-04-22
Rated 5 out of 5 by from Love It! I have been using this for about a year. My skin is softer, smoother and well hydrated. I use it at night after cleansing. My skin looks radiant!
Date published: 2019-04-21
Rated 5 out of 5 by from The Best I’ve been using H.A. for over 9 months and my face feels and looks amazing, the best part is my friends have noticed a “difference”, I love this product and visible results.
