Does Kate Somerville HydraKate Recharging Serum with Hyaluronic Acid work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using Kate Somerville HydraKate Recharging Serum with Hyaluronic Acid:

  • Strong humectant moisturizing. This lightweight, humectant-rich product, ideal for oily skin, has a moisturizing rating of 5.4 out of 10.

Lightweight moisturizer ideal for oily skin and a humectant boost for any skincare routine

According to CreamScan analysis, Kate Somerville HydraKate Recharging Serum with Hyaluronic Acid is quite moisturizing, with a moisturizing rating of 5.4 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 0.8 out of 10 and a maximum humectancy of 10 out of 10, primarily due to the high content of Glycerin (est. ≈6.0%), Betaine (est. ≈4.0%) and Propanediol (est. ≈3.0%).

This humectant-rich product, when used alone as a moisturizer, is ideal for oily skin, offering significant hydration in a lightweight, fast-absorbing formula with a minimal amount of occlusive ingredients. It’s also a great choice for people with normal skin who prefer lightweight moisturizers.

Such a humectant boost will also positively contribute to the moisturizing efficacy of any skincare routine when used as a step before applying the main moisturizer. This type of formulation is typically used in serums, where a light, fast-absorbing texture is key.

Please refer to the Ratings section below for details of the moisturizing rating calculation.

Questionable anti-wrinkle efficacy

According to CreamScan analysis, Kate Somerville HydraKate Recharging Serum with Hyaluronic Acid has a zero anti-wrinkle rating.

It contains Palmitoyl Tetrapeptide-7, an ingredient often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Palmitoyl Tetrapeptide-7 provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards. Therefore, this ingredient does not generate the anti-wrinkle rating.

Moisturizers, when used regularly, are proven to prevent wrinkle formation and even reduce existing wrinkles. Therefore, this product, like any other moisturizer, can deliver some anti-wrinkle effects through its moisturizing action.

Please refer to the Ratings section below for details of the anti-wrinkle rating calculation.
