Key Benefits of THANN Shiso Astringent Toner

 
These are the key benefits you can expect from using THANN Shiso Astringent Toner:
 

🔵 Lightweight Purely Humectant Moisturizing, Ideal for Oily Skin

According to CreamScan analysis, THANN Shiso Astringent Toner is quite moisturizing, with a moisturizing rating of 5.0 out of 10.

Is it more humectant or occlusive? 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%), Propanediol (est. ≈4.0%) and Glycerin (est. ≈3.0%).

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.

📌 Please note that this is not a complete list of benefits. We are in the process of enhancing our model to incorporate anti-pigmentation, exfoliation and anti-acne ratings.

Things to Be Aware Of: THANN Shiso Astringent Toner

 
CreamScan identified a few things to consider before adding THANN Shiso Astringent 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 THANN Shiso Astringent 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.

⚠️ Questionable anti-wrinkle efficacy

If one of your main reasons for choosing THANN Shiso Astringent Toner is its potential anti-aging effects, please note that, according to CreamScan analysis, it currently has a zero anti-wrinkle rating.

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

While this does not categorically rule out the possibility that Camellia Sinensis Leaf Extract may reduce wrinkles, its efficacy is not supported by convincing, vehicle-controlled, double-blind clinical studies - at least none that were available 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.

Pros & Cons of THANN Shiso Astringent Toner

 
Here’s an overview of the pros and cons of THANN Shiso Astringent Toner to help you decide if it’s the right choice for your skincare routine:
 

🟩 Pros:

✅ When used alone: Provides humectant-rich moisturizing ideal for oily skin
✅ As part of a routine: A humectant moisturizing boost, beneficial for any skin type
✅ Lightweight texture
 

⭕ Cons: 

⚠️ Only if used as a standalone moisturizer - it needs to be paired with occlusives to seal in humectants
⚠️ Questionable anti-wrinkle efficacy
   

Summary: THANN Shiso Astringent Toner

 
Based on the ingredient list analysis, CreamScan AI suggests that THANN Shiso Astringent Toner
, when used alone, delivers lightweight, humectant-rich moisturizing, making it ideal for oily skin. As part of a moisturizing routine, it provides a humectant boost, beneficial for all skin types.
 
That said, there are some things about THANN Shiso Astringent Toner worth noting.
 
Looking at its moisturizing profile, we found that it doesn’t contain any occlusive ingredients, potentially allowing the moisture attracted to the skin by humectants to evaporate. Therefore, if it’s used as the only moisturizer in a routine, it’s recommended to pair it with one that contains at least some occlusive ingredients, such as oils, butters, or silicones.
 
If one of your main reasons for considering THANN Shiso Astringent Toner is its potential anti-aging effects, please note that, according to CreamScan analysis, its anti-wrinkle efficacy is questionable. None of the ingredients in this product provide substantial evidence of their anti-wrinkle efficacy according to CreamScan Research Evaluation Standards.
