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.

  • 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

  • before

    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 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.

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.

Rated 5 out of 5 by from Love the results! I love this product and have seen dramatic improvement in terms of how smooth and firm my skin has become. I also read somewhere that you should apply to damp skin then seal with heavier moisturizers or wet your fingers and apply then seal. I do the latter and it works like a charm.

Rated 3 out of 5 by from I don't get it. I received a sample of a Skinceuticals product but it had denatured alcohol. I had to stop using it. Now I received a sample of the H.A. Intensifier and denatured alcohol is the 4th ingredient out of 38. I'd expect more out of Skinceuticals.

Rated 5 out of 5 by from Love it! It’s been 3 weeks since I started using this product am/pm. I should also mention that at the same time I introduced the Glycolic 10 at night to my regime as well. The clincher was a comparison photo that was taken at my dermatologist’s office 8 weeks ago. What an improvement! My skin is much firmer, feels smoother and no breakouts, no peeling. I can’t say whether it’s HA or the glycolic serum at night, but I won’t be without either one from here on in!

Rated 1 out of 5 by from Cannot tell a difference Honestly, there are Skinceutical products that are amazing and some that I cannot tell a difference. My intention is not to discredit the product, I just cannot notice any changes in my skin after using the product.

Rated 2 out of 5 by from Great product. Package fail I have used this product for a month and although I do like it a lot, I will not purchase again because of the packaging. It is misleading how much actual product you receive. It appears the bottle is full but when I could not get more out of the pump, I opened it up and the product is contained in a small plastic tube inside the bottle. I love the skinCeuticals products but this one is a miss.
Date published: 2019-09-23
Rated 4 out of 5 by from This product is a great. I brought this produce 3 weeks ago and my skin looks and feel great. I will definitely repurchase this product
Date published: 2019-09-21
Rated 3 out of 5 by from Wonderful product—absolutely horrible design I absolutely love this product. However, the packaging in the bottle will not allow all of the product to be released. It is unlikely that I would purchase again with such a poor design. At this price point, product should not be “captured” in the bottle and end up in the trash.

Rated 5 out of 5 by from Best Product Ever Bought this product as a recommendation after a dermal infusion. After I finished this bottle I couldn't stop talking about it. Ready for bottle #2.

Rated 5 out of 5 by from The best of All!!!! I start 5 Years ago with just eye cream And the sheer screen. But since I start the purple one my face looks better.

Rated 5 out of 5 by from Results results!! I have been using for about a month over CE and found it gave me more moisture and made my skin look bright and hydrated finally. I'm approx in my mid 50's and feel it has made my skin appear younger along with the other Skin C products I use.

Rated 5 out of 5 by from Helps smile lines This feels thick when you put it on but then melts in. There is no real small or tackiness after application. I think my fine lines are significantly better after using this for months and unless the winter is very dry mostly don’t feel the need for a moisturizer

Rated 5 out of 5 by from Stabilize My Skin I had run out of 2 bottles. It did't make any obvious changes on my face, but absolutely made my skin stable. There were less texture during the time period when I was using it. I would repurchase in the future:)
