Who It’s For

Any skin type or stage of aging seeking to balance hydration levels and maintain plump, springy skin that looks smoother and firmer.

How It Works

Hyaluronic acid (HA) is a polysaccharide that occurs naturally in the skin, keeping it hydrated and supporting the structural matrix. Adequate levels of HA give the skin a firm, smooth appearance. Our levels of hyaluronic acid diminish as we age, beginning as early as age 30, accelerated by environmental damage and oxidation. The result is skin with less volume and plumpness. The work of our bodies’ own hyaluronic acid is also diminished by dehydration, since one of the molecule’s most important roles is to retain moisture in the skin by holding many times its weight in water.

Hyaluronic Acid Hydration Serum delivers a high concentration of hyaluronic acid to the skin, in a moisture-boosting complex of supportive active ingredients. In addition, our serum is infused with protective antioxidants. Just a small amount applied to skin after cleansing and toning will help your skin retain its youthfully hydrated and supple appearance, with a smoother surface texture.

Hyaluronic acid can also improve the anti-aging effects of other active ingredients by enhancing their penetration into the deeper layers of the skin, as well as keeping the skin conditioned and receptive to other topical treatments. The unique function and dramatic effects of hyaluronic acid make it an essential part of any skincare regimen, no matter your skin type or skin concerns.

Plumps up your skin

This is honestly one of the most amazing products I have ever had the good fortune to find.... it literally plumps up my skin, it also gives my skin a healthy glow, ❤️❤️ This product!!!


This product saved my skin after having an allergic reaction to another product. It hydrated and reduced my inflammation. I use it nightly and my skin is very hydrated!


Perfect and my skin definitely feels much better after 6 months of use. Will be using this for a long time.


I use this at night before DMAE and collagen serums. I love how light it is. I have oily skin that tends to get very dry in certain areas so I'm very particular about what i use and would highly recommend this.


I have been using a combination of kate ryan products for a little over 2 months now. Ive essentially purchased the clear skin collection and have used multiple products. They are fantastic. This one in particular I like to use after my toner, and before my total nutrition night repair cream. Just a little background, i have struggled with acne since I was a teen, and am in my early twenties. It is constant and despite focusing on stress, diet, etc, it still plagues me. Not cystic, or even exclusive to one area of the face, but just constant enough to really be frustrating. genetics and other factors i hadnt figured out. ive used countless natural products and havent seen results. I have seen the most results ever using Kate Ryan products. For this product in particular, I do not use it on its own as a moisturizer, but like it at night because a) i cant use it in the morning or else it flakes under my makeup and b) sodium hyaluronate holds water to the skin making your skin look plumper and dewier. That is important to have with a balance of the oils on your skin so the outside lipid barrier is moisturized but it has enough water inside it to hold as well. Honestly, from my skins perspective, I havent noticed a dramatic difference in dewy plump skin, but I have young skin to begin with. I do, however, find that with my routine, i wake up to a lot more glowy skin than I used to. And it feels really cooling and refreshing, so I love to have it as an addition. Over all, I think having a sodium hyaluronate addition to your skin care is a really important step, and I love this serum more than any other products or mists Ive tried!
