Key Benefits of 111SKIN Celestial Black Diamond Brightening Essence

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

Lightweight Humectant Moisturizer Ideal for Oily Skin

According to CreamScan analysis, 111SKIN Celestial Black Diamond Brightening Essence is quite moisturizing, with a moisturizing rating of 4.1 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 very high humectancy of 8.1 out of 10, primarily due to the high content of Propanediol (est. ≈6.0%).

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.

Rich in Skin-Protecting Antioxidants

We estimate that 111SKIN Celestial Black Diamond Brightening Essence is rich (> 3%) in antioxidants, specifically Bambusa Vulgaris Water (est. ≈4.0%).

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.

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: 111SKIN Celestial Black Diamond Brightening Essence

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

Questionable anti-wrinkle efficacy

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

It contains Copper Tripeptide-1, an ingredient often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Copper Tripeptide-1 provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards.

While this does not categorically exclude the possibility that Copper Tripeptide-1 may reduce wrinkles, its efficacy is not supported by convincing, vehicle-controlled, double-blind clinical studies - at least none that were accessible to the CreamScan team at the time of publication.

Therefore, this ingredient does 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.

Propanediol
Est. %6
Function
Origin
PropanediolAn excellent solvent capable of mixing water with normally water-insoluble ingredients. It also functions as a humectant due to its water-loving alcohol groups. Propanediol can control the viscosity of a product by reducing its thickness.
Bambusa Vulgaris Water

Alcohol
Est. %0.3
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.
Sodium Phytate
Est. %0.3
Function
Origin
Sodium PhytateSodium phytate is a chelating agent that serves to remove heavy metal ions from water. Removing metal ions helps other ingredients, such as antioxidants and preservatives, to perform better and keep products from separating.
Tocopheryl Acetate
Est. %0.3
Function
Origin
Tocopheryl Acetate

An antioxidant derivative of tocopherol (vitamin E). It helps to protect cells from free radicals and UV damage through the conversion to active vitamin E in the skin. It is more stable than tocopherol.

Glycyrrhiza Glabra (Licorice) Root Extract

Potassium Sorbate
Est. %0.3
Function
Origin
Potassium SorbateA preservative widely used in food and personal care products, available from natural sources or synthetically produced. Potassium sorbate works by inhibiting the growth of yeasts, molds, and some bacteria.
Sodium Benzoate
Est. %0.3
Function
Origin
Sodium BenzoateA preservative that usually works in combination with other preservatives. It has to be at low pH (<5.5) to be effective.
Phenoxyethanol
Est. %0.3
Function
Origin
PhenoxyethanolThe most frequently used preservative in skincare. It is a clear, oil-like liquid synthetic substance that protects products from harmful bacteria and yeast, whilst still leaving skin microflora unharmed. It is confirmed by research to be harmless.
Glycerin
Est. %0.3

Xanthan Gum
Est. %0.3
Function
Origin

Glycine Soja (Soybean) Oil
Est. %0.3
Function

Sodium Oleate
Est. %0.3
Function
Origin
Sodium OleateSodium oleate is a sodium salt of oleic acid. It has the typical properties of soap: it foams in water and emulsifies oil into tiny droplets. It comes in the form of a white powder and is used in skincare products exactly as you would expect – as a cleanser and emulsifier.
Benzoic Acid
Est. %0.3
Function
