Key Benefits of Sato Yakuhin Medimerry Aqfair Skin Toner

 
These are the key benefits you can expect from using Sato Yakuhin Medimerry Aqfair Skin Toner:
 

🔵 Lightweight Purely Humectant Moisturizing, Ideal for Oily Skin

According to CreamScan analysis, Sato Yakuhin Medimerry Aqfair Skin Toner is quite moisturizing, with a moisturizing rating of 5.0 out of 10.

Is it more humectant or occlusive? Question icon The Humectancy (from 0 to 10) is based on the amount of humectants in the formula and indicates how well the product can attract moisture to the skin. Humectants are effective moisturizers that work well for all skin types. The Occlusivity (from 0 to 10) is based on the amount of occlusives in the formula and indicates how effective the product is at sealing moisture into the skin. Occlusive moisturizers are ideal for those with dry skin. Question icon The Humectancy (from 0 to 10) is based on the amount of humectants in the formula and indicates how well the product can attract moisture to the skin. Humectants are effective moisturizers that work well for all skin types. The Occlusivity (from 0 to 10) is based on the amount of occlusives in the formula and indicates how effective the product is at sealing moisture into the skin. Occlusive moisturizers are ideal for those with dry skin. It is purely humectant. It has zero occlusivity (we didn't find any occlusive ingredients on the ingredient list) and a maximum humectancy of 10 out of 10, primarily due to the high content of Butylene Glycol (est. ≈6.0%), Ulmus Davidiana Root Extract (est. ≈4.0%) and Glycine (est. ≈2.0%).

This humectant-rich product, when used alone as a moisturizer, is ideal for oily skin, providing significant hydration in a lightweight, fast-absorbing formula without any occlusive ingredients.

📌 Certain studies suggest that humectants alone may not effectively moisturize the skin. If you use this product as your only moisturizer, we recommend following it with one that contains at least some occlusive ingredients.

💧 A Humectant Boost for Any Skincare Routine

But it’s not limited to oily skin - such a humectant boost will also positively contribute to the moisturizing efficacy of any skincare routine when used as a step before applying the main moisturizer. This type of formulation is typically used in serums, where a light, fast-absorbing texture is key.

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

🍀 Rich in Skin-Protecting Antioxidants

We estimate that Sato Yakuhin Medimerry Aqfair Skin Toner is rich (> 3%) in antioxidants, specifically Ulmus Davidiana Root Extract (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: Sato Yakuhin Medimerry Aqfair Skin Toner

 
CreamScan AI identified a few things to consider before adding Sato Yakuhin Medimerry Aqfair Skin Toner to your skincare routine:
 

⚠️ If It’s Your Only Moisturizer, It Needs to Be Paired with Some Occlusives

While humectants are highly effective at attracting water to the skin, studies (J. N. Kraft, C. W. Lynde) suggest they may not be efficient when used alone.

One major drawback of purely humectant moisturization is that the water attracted by humectants to the upper layers of the skin can evaporate completely into the environment through transepidermal water loss (TEWL). Adding occlusive ingredients helps seal this moisture into the skin and prevent further water loss.

If you’re using Sato Yakuhin Medimerry Aqfair Skin Toner as your only moisturizer, consider pairing it with one that contains at least some occlusive ingredients, such as oils, butters, or silicones. These work alongside humectants to create a protective barrier, locking in hydration and ensuring longer-lasting moisturization. The amount of occlusive needed depends on your skin type - the drier the skin, the more occlusives it requires.

If this product is used not as a standalone moisturizer but as part of your skincare routine, such as a toner or serum, it should be applied before your main moisturizer (unless it's a sunscreen), which will provide the necessary occlusivity on top of it.

Pros & Cons of Sato Yakuhin Medimerry Aqfair Skin Toner
