Key Benefits of Kosas Plump + Juicy Lip Booster Buttery Treatment

 
These are the key benefits you can expect from using Kosas Plump + Juicy Lip Booster Buttery Treatment:
 

Very Rich Moisturizer with the Right Occlusivity for Very Dry Skin

According to CreamScan analysis, Kosas Plump + Juicy Lip Booster Buttery Treatment is quite moisturizing, with a moisturizing rating of 5.6 out of 10.

Is it more humectant or occlusive? Significantly more occlusive. It has a low Humectancy of 1.2 out of 10 and a maximum Occlusivity of 10 out of 10, primarily due to the high content of Ricinus Communis (Castor) Seed Oil (est. ≈22.0%), Butyrospermum Parkii (Shea) Butter (est. ≈11.0%) and Simmondsia Chinensis (Jojoba) Seed Oil (est. ≈2.0%).

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 Kosas Plump + Juicy Lip Booster Buttery Treatment 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.

Rich in Skin-Protecting Antioxidants

We estimate that Kosas Plump + Juicy Lip Booster Buttery Treatment is rich (> 3%) in antioxidants, specifically Tocopheryl Nicotinate (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: Kosas Plump + Juicy Lip Booster Buttery Treatment

 
CreamScan AI identified a few things to consider before adding Kosas Plump + Juicy Lip Booster Buttery Treatment to your skincare routine:
 

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.

Needs to Be Paired with Extra Humectants for Optimal Moisturizing Efficacy

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 Kosas Plump + Juicy Lip Booster Buttery Treatment contains a low level of humectants.

People with dry skin would definitely benefit from adding more humectants to their moisturizing routine beyond what this product offers. If this is your only moisturizer, it may be worth including a humectant-rich product, such as a serum, in your skincare routine.

Questionable anti-wrinkle efficacy

If one of your main reasons for choosing Kosas Plump + Juicy Lip Booster Buttery Treatment is its potential anti-aging effects, please note that, according to CreamScan analysis, it currently has a zero anti-wrinkle rating.

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

While this does not categorically exclude the possibility that Palmitoyl 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.
