The HydraKate line was recently unveiled by skin care company Kate Somerville.
Hyaluronic acid with a dual weight is used in the HydraKate Recharging Serum to hydrate skin.
Below, an editor describes her experience using the serum.
Los Angeles does not get as cold as many other places around the world during the winter, but it does get incredibly dry. In the cooler months in California, my skin, which is already chronically dehydrated, requires a lot more care. Hyaluronic acid by itself is always my go-to throughout the year, but when the weather is this dry, I like to step it up with a more complex hydrating serum.

The Kate Somerville HydraKate Recharging Serum With Hyaluronic Acid ($78) is the object of my most recent obsession. Hyaluronic acid is the star ingredient in this serum, but it also gets a serious boost from the company’s AquaPort Technology, which pushes dual-weight hyaluronic acid deeper and faster into the skin.
AquaPort Technology: What is it? In any case, it was created at Kate Somerville’s Skin Health Experts Clinic and replicates the results of her renowned microchanneling treatment (aka what happens when microneedling is performed). The AquaPort Technology aims to open up water pathways to deliver quicker, deeper, and longer-lasting hydration, similar to a microchanneling facial. The dual-weight hyaluronic acid, which is designed to bind moisture into different layers of the skin, can therefore penetrate deeper and increase the visibility of the plumping and hydrating effects.

Beyond its list of advanced ingredients, the serum simply feels good when applied. Although it is thin, it isn’t so thin that you have to question its effectiveness. I’ve started using it as both the first step in my nighttime routine and my daytime moisturiser under SPF because it sinks into the skin and instantly gives me a slightly more “glazed” appearance.
I can definitely tell the difference in my skin on days when I skip these particular steps, especially during the cooler months, even though the serum is a little on the pricey side. It absorbs into my dry skin like a hot cup of coffee on a chilly winter morning.
