Key Benefits of Knours. Sweet Rescue Bubble Burst Serum

 
These are the key benefits you can expect from using Knours. Sweet Rescue Bubble Burst Serum:
 

Lightweight Humectant Moisturizer Ideal for Oily Skin

According to CreamScan analysis, Knours. Sweet Rescue Bubble Burst Serum is quite moisturizing, with a moisturizing rating of 5.8 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 1.6 out of 10 and a maximum humectancy of 10 out of 10, primarily due to the high content of Isopentyldiol (est. ≈4.0%) and Niacinamide (est. ≈2.0%).

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.

A Humectant Boost for Any Skincare Routine

But it’s not limited to oily skin - 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.

Modest Anti-Wrinkle Efficacy

According to CreamScan analysis, Knours. Sweet Rescue Bubble Burst Serum has a modest level of anti-wrinkle efficacy, rated 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, Knours. Sweet Rescue Bubble Burst Serum also contains Adenosine, an ingredient often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Adenosine 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.
 

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

Please note that this is not a complete list of benefits. We are in the process of enhancing our AI model to incorporate anti-pigmentation, exfoliation and anti-acne ratings.
