Key Benefits of Dear, Klairs Fundamental Nourishing Eye Butter

 
These are the key benefits you can expect from using Dear, Klairs Fundamental Nourishing Eye Butter:
 

Perfect Moisturizer for Normal to Dry Skin with a Balanced Texture, Neither Too Light nor Too Heavy

According to CreamScan analysis, Dear, Klairs Fundamental Nourishing Eye Butter is highly moisturizing, with a moisturizing rating of 7.4 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a maximum humectancy of 10 out of 10, primarily due to the substantial concentration of Glycerin (est. ≈9.0%) and Betaine (est. ≈2.5%), and a moderate occlusivity of 4.8 out of 10, mainly due to the high content of Stearic Acid (est. ≈6.0%) and Helianthus Annuus (Sunflower) Seed Oil (est. ≈3.0%).

This type of moisturizer is ideal for people with normal skin who want maximum hydration in a formula with a balanced texture - neither too light nor too heavy. It combines a high concentration of humectants with a significant amount of occlusive ingredients to deliver effective dual-action moisturizing for normal skin.

This product may also be a good choice for people with normal to dry skin for daily hydration, as it balances significant moisturizing potential with a balanced texture, neither too light nor too heavy.

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

Rich in Skin-Protecting Antioxidants

We estimate that Dear, Klairs Fundamental Nourishing Eye Butter is rich (> 3%) in antioxidants, specifically Caffeine (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.

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: Dear, Klairs Fundamental Nourishing Eye Butter

 
CreamScan AI identified a few things to consider before adding Dear, Klairs Fundamental Nourishing Eye Butter to your skincare routine:
 

Questionable anti-wrinkle efficacy

If one of your main reasons for choosing Dear, Klairs Fundamental Nourishing Eye Butter 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 Caffeine, Camellia Sinensis Leaf Extract, Melia Azadirachta Leaf Extract, Acetyl Hexapeptide-8, and Copper Tripeptide-1. 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 exclude 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 accessible 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.
