Does Credentials RosaCalm Skin Serum work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using Credentials RosaCalm Skin Serum:

  • Strong humectant moisturizing. This lightweight, humectant-rich product, ideal for oily skin, has a moisturizing rating of 5.2 out of 10.
  • Soothing: Credentials RosaCalm Skin Serum contains a high concentration of soothing ingredients, which may help to reduce irritation and calm the skin.
  • Antioxidant protection.

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

According to CreamScan analysis, Credentials RosaCalm Skin Serum is quite moisturizing, with a moisturizing rating of 5.2 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 0.4 out of 10 and a maximum humectancy of 10 out of 10, primarily due to the high content of Glycerin (est. ≈6.0%) and Beta-Glucan (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, Credentials RosaCalm Skin Serum has a zero anti-wrinkle rating.

It contains some ingredients often marketed as effective in reducing wrinkles, specifically Beta-Glucan, Copper PCA, and Ubiquinone. However, the studies supporting the anti-wrinkle claims of these ingredients provide insufficient evidence of efficacy according to CreamScan Research Evaluation Standards. Therefore, these ingredients do 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.

Rich in skin-protecting antioxidants

We estimate that Credentials RosaCalm Skin Serum is rich (> 3%) in antioxidants, specifically Beta-Glucan (est. ≈3.0%) and Glycine Soja (Soybean) Seed Extract (est. ≈2.0%).

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.

Skin soothing and calming potential

Based on the ingredient list analysis, Credentials RosaCalm Skin Serum is rich (> 5%) in soothing ingredients, particularly Beta-Glucan (est. ≈3.0%) and Glycine Soja (Soybean) Seed Extract (est. ≈2.0%).

When applied to the skin, compounds of soothing ingredients, such as triglycerides, phospholipids, fatty acids, phenolic compounds, and antioxidants, work together to soothe the skin through various mechanisms: reducing inflammation, promoting wound healing, repairing the skin barrier, and providing antimicrobial and antioxidant activities.
