Key Benefits of Krisment K-Serum Brightening & Firming

 
These are the key benefits you can expect from using Krisment K-Serum Brightening & Firming:
 

Lightweight Purely Humectant Moisturizing, Ideal for Oily Skin

According to CreamScan analysis, Krisment K-Serum Brightening & Firming is quite moisturizing, with a moisturizing rating of 5.0 out of 10.

Is it more humectant or occlusive? It is purely humectant. It has zero occlusivity (we didn't find any occlusive ingredients on the ingredient list) and a maximum humectancy of 10 out of 10, primarily due to the high content of Glycerin (est. ≈6.0%), Cladosiphon Okamuranus Extract (est. ≈3.0%) and Butylene Glycol (est. ≈2.0%).

This humectant-rich product, when used alone as a moisturizer, is ideal for oily skin, providing significant hydration in a lightweight, fast-absorbing formula without any occlusive ingredients.

Tip: Certain studies suggest that humectants alone may not effectively moisturize the skin. If you use this product as your only moisturizer, we recommend following it with one that contains at least some occlusive ingredients.

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.

Considerable Anti-Wrinkle Efficacy

According to CreamScan analysis, Krisment K-Serum Brightening & Firming has a moderate anti-wrinkle rating of 4.7 out of 10.

It contains 2 active ingredients with proven anti-wrinkle efficacy:

  • Retinol (est. ≈0.1%),
     the most effective non-prescription anti-wrinkle ingredient. Numerous clinical studies have shown its positive effects at concentrations as low as 0.1%. A study with 36 participants (Kafi et al.) confirmed that a lotion containing 0.4% retinol reduced wrinkle severity by 21% after 24 weeks of use, compared to the same formulation without retinol (vehicle).
  • Niacinamide (est. ≈1.5%),
     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).
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.

Rich in Skin-Protecting Antioxidants

We estimate that Krisment K-Serum Brightening & Firming is rich (> 3%) in antioxidants, specifically Niacinamide (est. ≈1.5%), Hydroxyacetophenone (est. ≈1.3%) and Hyaluronic Acid (est. ≈0.3%).

A key benefit of antioxidants is their ability to reduce oxidative stress caused by free radicals and therefore prevent accelerated skin aging. Studies also show that antioxidants can protect against environmental damage such as UV radiation and pollution, and help reduce inflammation and skin redness.

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.

Things to Be Aware Of: Krisment K-Serum Brightening & Firming

 
CreamScan AI identified a few things to consider before adding Krisment K-Serum Brightening & Firming to your skincare routine:
 

If It’s Your Only Moisturizer, It Needs to Be Paired with Some Occlusives

While humectants are highly effective at attracting water to the skin, studies (J. N. Kraft, C. W. Lynde) suggest they may not be efficient when used alone.

One major drawback of purely humectant moisturization is that the water attracted by humectants to the upper layers of the skin can evaporate completely into the environment through transepidermal water loss (TEWL). Adding occlusive ingredients helps seal this moisture into the skin and prevent further water loss.

If you’re using Krisment K-Serum Brightening & Firming as your only moisturizer, consider pairing it with one that contains at least some occlusive ingredients, such as oils, butters, or silicones. These work alongside humectants to create a protective barrier, locking in hydration and ensuring longer-lasting moisturization. The amount of occlusive needed depends on your skin type - the drier the skin, the more occlusives it requires.

If this product is used not as a standalone moisturizer but as part of your skincare routine, such as a toner or serum, it should be applied before your main moisturizer (unless it's a sunscreen), which will provide the necessary occlusivity on top of it.
