Key Benefits of 111SKIN Celestial Black Diamond Retinol Oil

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

Very Rich Moisturizer with the Right Occlusivity for Very Dry Skin

According to CreamScan analysis, 111SKIN Celestial Black Diamond Retinol Oil is quite moisturizing, with a moisturizing rating of 5.0 out of 10.

Is it more humectant or occlusive? It is purely occlusive. It has zero Humectancy (we didn't find any humectant ingredients on the ingredient list) and a maximum Occlusivity of 10 out of 10, primarily due to the high content of Caprylic/Capric Triglyceride (est. ≈22.0%), Hydrogenated Palm Oil (est. ≈11.0%) and Helianthus Annuus (Sunflower) Seed Oil (est. ≈6.0%).

This type of product, when used as a standalone moisturizer, can deliver an exceptional level of occlusive hydration that is adequate for dry to very skin. The occlusive profile of 111SKIN Celestial Black Diamond Retinol Oil suggests a rich, thick texture, making it perfectly suited for dry skin.

Please refer to the Ratings section below for details of the moisturizing rating calculation.

Potent Anti-Wrinkle Efficacy

According to CreamScan analysis, 111SKIN Celestial Black Diamond Retinol Oil has a maximum anti-wrinkle rating of 10.0 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Retinol (est. ≈1.0%), 
 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).
 
Among others, 111SKIN Celestial Black Diamond Retinol Oil also contains Retinyl Palmitate, an ingredient often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Retinyl Palmitate provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards. Therefore, this ingredient does not contribute to the anti-wrinkle rating.
 

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

Rich in Skin-Protecting Antioxidants

We estimate that 111SKIN Celestial Black Diamond Retinol Oil is rich (> 3%) in antioxidants, specifically Vitis Vinifera (Grape) Seed Oil (est. ≈3.0%).

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 Retinol Oil

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

May Increase Skin Photosensitivity Due to Retinol

This product contains retinol, which offers powerful anti-wrinkle benefits. The mechanism behind retinol’s action is boosting cell turnover. This process exposes new, more delicate skin, making it more vulnerable to sun damage.

As a result, using products with retinol may increase the skin's sensitivity, making it more prone to sunburn or irritation when exposed to UV rays.

To protect the skin, dermatologists recommend applying a broad-spectrum sunscreen with at least SPF 30 throughout the duration of retinol treatment, along with avoiding direct sun exposure. Retinol should be used at night, as it is sensitive to sunlight and can lose its potency when exposed to UV rays.

Please always check the manufacturer's instructions for using the retinol-containing products, either on their website or product label.

Best for Very Dry Skin - May Be Too Thick for Other Skin Types

With exceptional occlusivity, this product is optimal for moisturizing dry and very dry skin but may be too thick for other skin types, including normal, and especially combination and oily skin.

If you have oily, combination, or normal skin and are considering purchasing this product for the first time, it might be a good idea to try a sample before buying.

If It’s Your Only Moisturizer, It’s Better When Paired with Some Humectants

An ideal moisturizer for any skin type should balance the right level of occlusivity (depending on skin type) with a significant amount of humectants, while 111SKIN Celestial Black Diamond Retinol Oil contains no humectants at all.

People with dry skin would definitely benefit from adding water-binding humectants to their moisturizing routine for effective dual-action moisturizing. If this is your only moisturizer, it may be worth including a humectant-rich product, such as a serum, in your skincare routine.
