Does SK-II SKINPOWER Essence Serum work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using SK-II SKINPOWER Essence Serum:

  • Strong humectant moisturizing. This lightweight, humectant-rich product, ideal for oily skin, has a moisturizing rating of 5.1 out of 10.
  • Some anti-wrinkle efficacy: SK-II SKINPOWER Essence Serum has an anti-wrinkle rating of 3.0 out of 10 so you may expect some, although limited, effect on wrinkles.

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

According to CreamScan analysis, SK-II SKINPOWER Essence Serum is quite moisturizing, with a moisturizing rating of 5.1 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 0.2 out of 10 and a maximum humectancy of 10 out of 10, primarily due to the high content of Galactomyces Ferment Filtrate (est. ≈6.0%), Glycerin (est. ≈4.0%) and Butylene Glycol (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.

Some anti-wrinkle efficacy

According to CreamScan analysis, SK-II SKINPOWER Essence Serum has a slight anti-wrinkle rating of 3.0 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Niacinamide (est. ≈2.0%), 
 one of the most effective and well-researched anti-wrinkle ingredients. A clinical study involving 30 participants (Kawada et al.) confirmed that a cream with 4% niacinamide reduced the average depth of wrinkles around the eyes by 9% after 8 weeks of use, compared to a vehicle (the same formulation without niacinamide).
 
Among others, SK-II SKINPOWER Essence Serum also contains Palmitoyl Pentapeptide-4, an ingredient often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Palmitoyl Pentapeptide-4 provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards. Therefore, this ingredient does not contribute to 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.
