Key Benefits of 111SKIN Celestial Black Diamond Serum

 
These are the key benefits you can expect from using 111SKIN Celestial Black Diamond Serum:
 

🔵 Lightweight Humectant Moisturizer Ideal for Oily Skin

According to CreamScan analysis, 111SKIN Celestial Black Diamond 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 very high humectancy of 9.9 out of 10, primarily due to the high content of Glycerin (est. ≈6.0%) and Sorbitol (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.

💧 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.

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

Things to Be Aware Of: 111SKIN Celestial Black Diamond Serum

 
CreamScan identified a few things to consider before adding 111SKIN Celestial Black Diamond Serum to your skincare routine:
 

⚠️ Questionable anti-wrinkle efficacy

If one of your main reasons for choosing 111SKIN Celestial Black Diamond Serum is its potential anti-aging effects, please note that, according to CreamScan analysis, it currently has a zero anti-wrinkle rating.

It contains some ingredients often marketed as effective in reducing wrinkles, specifically Retinyl Palmitate, Sodium Ascorbyl Phosphate, and Centella Asiatica Extract. However, the studies supporting the anti-wrinkle claims of these ingredients provide insufficient evidence of efficacy according to CreamScan Research Evaluation Standards. 

While this does not categorically rule out the possibility that these ingredients may reduce wrinkles, their efficacy is not supported by convincing, vehicle-controlled, double-blind clinical studies - at least none that were available to the CreamScan team at the time of publication.

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.

Ingredients explained

Water
Est. %80
Function
Origin
WaterThe most used ingredient in skincare. Its concentration defines the product texture: rich creams may have about 50% of water while a light jelly about 90%. Water doesn’t moisturize the skin by itself and is used in skincare as a solvent for other ingredients.
Glycerin
Est. %6
Function
Origin
Glycerin

The most popular moisturizing ingredient in the world. It is a powerful humectant – cheap yet very effective.

Alcohol
Est. %4
Function
Origin
AlcoholAn effective antimicrobial ingredient that kills bacteria, fungi, and even some viruses. It is also an excellent solvent and astringent. Alcohol helps to create lighter and less viscous products. It can, however, be dehydrating and skin-sensitizing.
Sorbitol
Est. %3
Function
Origin
SorbitolA sweet-tasting alcohol derived from glucose. Aside from its sweet taste (for which it is used as a very common sweetener), Sorbitol is also very good at retaining water and is used in skincare as a humectant.
Isopropyl Myristate
Est. %2
Function
Origin
Isopropyl MyristateA fast-spreading, cost-effective, non-greasy emollient that is typically used for lubrication, spreadability, or to remove “tackiness” from a product. Isopropyl Myristate is listed as a common comedogenic ingredient by acne.org.
Benzyl Alcohol
Est. %0.3
Function
Origin
Benzyl Alcohol

Est. %0.3
Function
Origin

Xanthan Gum
Est. %0.3
Function
Origin
