Rich Moisturizer with the Right Occlusivity for Dry Skin

According to CreamScan analysis, Fourth Ray Beauty Oat Face Milk Moisturizer is highly moisturizing, with a moisturizing rating of 7.2 out of 10.

It has a moderate humectancy of 4.9 out of 10, primarily due to the substantial concentration of Glycerin (est. ≈3.0%), and a very high occlusivity of 9.5 out of 10, mainly due to the significant content of Caprylic/Capric Triglyceride (est. ≈9.0%) and Simmondsia Chinensis (Jojoba) Seed Oil (est. ≈6.0%).

This type of product, when used as a standalone moisturizer, can deliver a substantial level of occlusive hydration that is adequate for dry skin. The occlusive profile of Fourth Ray Beauty Oat Face Milk Moisturizer suggests a rich, thick texture, making it perfectly suited for dry skin.

Rich in Skin-Protecting Antioxidants

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: Fourth Ray Beauty Oat Face Milk Moisturizer

 
CreamScan AI identified a few things to consider before adding Fourth Ray Beauty Oat Face Milk Moisturizer to your skincare routine:
 

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

With high occlusivity, this product is optimal for dry skin but may be too thick for combination and especially oily skin. Even on normal skin, it can feel too rich depending on the quantity applied, the environment, and individual preferences.

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 Fourth Ray Beauty Oat Face Milk Moisturizer contains a moderate 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.
