    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 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!
