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. This hyaluronic acid serum may be used as part of a home skincare regimen after dermal fillers; always consult with your physician for individual at-home advice.

  • 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

    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 Plumping! I bought this serum a few days ago and have already been impressed by the results. My face looks and feels more alive after use. I see a plumpness to my skin and just overall looks more radiant. Definitely recommend this serum!

Rated 2 out of 5 by from Did not absorb This was the first product I used in this line, along with Ferulic and it just would not absorb in to my skin! It constantly rolled off into balls, even if using just a drop. I love so many other products from here but I was disappointed in this one. I continued to use, thinking something had to get absorbed, and I saw no change. I’ve since switched to Ferulic acid, Metcall renewal, and age interrupter and much prefer those.

Rated 5 out of 5 by from Best Hyaluronic Acid EVER I had a TIA a few years ago and started using many types of hyaluronic acid products and SkinCeutials has been the best. Many have asked if I had fillers in my cheek affected. Imagine their surprise when I said “No”!! Best plumber serum ever.

Rated 5 out of 5 by from My Fave Hyaluronic Acid I blend this serum with CE Ferulic. So nice to the skin. I really love hyaluronic acid. Even my essence is also an hyaluronic acid mixed. One time I combined the CE Ferulic plus this hyaluronic before I moisturize my face. A holy grail result. An elasticity texture. The price is bit pricey, because of the brand :) It is an Odorless serum when it comes to smell. Morning its CE Ferulic. Night its Hyaluronic Acid. To be honest, its difficult to find a suitable pair of products that matches with your skin care type. I am a combination/sensitive type of skin. Since I found this product, I retained as my skin care. I love it❤️

Rated 5 out of 5 by from a gem in skincare !!! Skin care has always confused me. How do we really know what to choose when there are so many products? For me, the answer is to stick with what gets you results. Skinceuticals is a trusted skincare brand and with the couple of products I've used , I've definitely gotten results. This serum has brightened my dull, uneven toned skin and given my face a glow. At 46, I'd accepted my glow was just going t have to come from a makeup palette, but my face is GLOWING. I'm forever grateful to Skinceuticals. The hyaluronic acid intensifier is now a staplease of my skin care regimen.

Rated 5 out of 5 by from AMAZING ★★★★★ 5 out of 5 stars. · 23 days ago MY FACE FEELS SO SOFT AND SMOOTH I have been using this product twice a day and love it. My face feels so soft and smooth after I apply that sometimes I forget to moisturize afterwards. I am still waiting to see if my lines soften but I would be very surprised if they didn’t.
