    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 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.
