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.

  • 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

    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 My New Favorite! I have been using the HA Intensifier for 4 weeks. I love this new serum. I am 52 and have been using SkinCeuticals products for 13 years now. This serum has a lovely berry color to it, although it does not look like berry when put on your face. I use this in the morning after my CE Ferulic serum. The funny part, I couldn't figure out that when I licked the edge of my mouth, I kept tasting something sweet. I figured it out, it is the licorice root in the serum. The only thing I am not fond of is the dropper that comes with the bottle. It is difficult to get the product out of the dropper. Maybe it is because the serum is a bit on the thick side. This is definitely a staple in my SkinCeuticals regimen.

Rated 5 out of 5 by from Perfect For Firming and Creating a Healthy Glow! I received this product as a free sample for testing. I loved it so much I had to purchase a full-sized bottle! I use this serum in the morning and at night before I go to sleep. The elasticity for my skin has been drastic and I keep it in my fridge and use it cold! This is my pro tip for all liquid products for my skin care. I really like this product because it has given me a healthy glow in the past couple of weeks that I don't find during the dry, winter season!

Rated 5 out of 5 by from So moisturizing! I received a sample of this product from Influenster and Skinceuticals to try for free. I decided to try this product on a day my skin was really angry at me. My sensitive skin had been put through the ringer yesterday, applying 2 separate make up looks. It was extremely cold when I went out and about today. Tonight when I put this on before bed, it felt amazingly moisturizing. It felt so nice going on my sensitive and angry skin. I know that this product will be wonderful to use on a daily basis and keep my skin looking and feeling great!

Rated 4 out of 5 by from So far so good! I had been researching the top Hyaluronic Acid serums and recently discovered the HYALURONIC ACID INTENSIFIER (H.A.). The ingredients seemed super impressive so I added it to my wishlist and was pleasantly surprised to receive a sample via Influenster. So far I have noticed some improvement in my skin looking a bit smoother and fine lines reduced. Would love to give this a try for a full month in order to determine if it will become my holy grail HA serum!

Rated 4 out of 5 by from So far so good I received a free sample of this product and have used about half of the sample in the last week. So far I like it but I haven't seen any real changes yet. I have been applying this product at night and my skin is very soft in the morning. My primary concern is skin discoloration and so far I haven't noticed any changes in that department but I will continue to use my sample until it is gone. The product is pricey so I am unsure if I would repurchase.

Rated 5 out of 5 by from LOVE THIS! I've been using this serum for at least a couple of weeks now and really love it. I put it on at night with my other nightly routine and I can really tell the difference in the morning! I forgot it the other night and knew exactly what I forgot when I got up! It is a really good primer for your foundation in the morning, it gives a nice glow! This is one product I don't think I'll be without in the future!

Rated 5 out of 5 by from Love! Received a sample size complimentary to review. Not sure if I’ll be able to use long enough to see full results but honestly loved the product right away. Feels great on skin and saw my dry areas feel and look so much better. I have sensitive and acne prone skin but this has been gentle and have seen zero negative side affects.

Rated 5 out of 5 by from Glowing skin I love how soft my skin felt after just one use. I have sensitive skin and thr product was not drying or oily which i liked very much. The product is a bit thick but once its on the skin it applies very smoothly . After two days of using the product my skin has an even tone and a great glow which i love .
