Key Benefits of Yon-Ka Defense+

 
These are the key benefits you can expect from using Yon-Ka Defense+:
 

Very Rich Moisturizer with the Right Occlusivity for Very Dry Skin

According to CreamScan analysis, Yon-Ka Defense+ 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 Helianthus Annuus (Sunflower) Seed Oil (est. ≈45.0%), Camellia Japonica Seed Oil (est. ≈6.0%) and Plukenetia Volubilis Seed Oil (est. ≈3.0%).

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 Yon-Ka Defense+ 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 Yon-Ka Defense+ is rich (> 3%) in antioxidants, specifically Plukenetia Volubilis Seed Oil (est. ≈3.0%) and Punica Granatum Seed Oil (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: Yon-Ka Defense+

 
CreamScan AI identified a few things to consider before adding Yon-Ka Defense+ 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 Yon-Ka Defense+ 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.

Pros & Cons of Yon-Ka Defense+

 
Here’s an overview of the pros and cons of Yon-Ka Defense+ to help you decide if it’s the right choice for your skincare routine:
 

Pros:

  • Provides the right level of occlusivity to moisturize dry to very dry skin
  • Rich in antioxidants that combat oxidative stress associated with accelerated skin aging and defend against environmental damage

Cons: 

  • May feel too rich and thick on skin types other than dry
  • Ideally needs to be paired with extra humectants for optimal moisturizing efficacy
