Key Benefits of COSRX Refresh AHA BHA Vitamin C (ABC) Daily Toner

 
These are the key benefits you can expect from using COSRX Refresh AHA BHA Vitamin C (ABC) Daily Toner:
 

🔵 Lightweight Purely Humectant Moisturizer Suitable for Oily Skin

According to CreamScan analysis, COSRX Refresh AHA BHA Vitamin C (ABC) Daily Toner is lightly moisturizing, with a moisturizing rating of 2.2 out of 10.

Is it more humectant or occlusive? Purely humectant. It has zero occlusivity (we didn't find any occlusive ingredients on the ingredient list) and a moderate humectancy of 4.4 out of 10, primarily due to the high content of Butylene Glycol (est. ≈2.0%).

This product, when used alone as a moisturizer, can provide light humectant hydration in a fast-absorbing formula without any occlusive ingredients. This could work for people with oily skin who need a basic level of hydration.

❗️ 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 Add-on for Any Skincare Routine

But it’s not limited to oily skin - since it contains a moderate amount of humectants, such a humectant add-on will also positively contribute to the moisturizing efficacy of any skincare routine when used as a step before applying the main moisturizer.

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

🟣 Modest Anti-Wrinkle Efficacy

According to CreamScan analysis, COSRX Refresh AHA BHA Vitamin C (ABC) Daily Toner has a modest level of anti-wrinkle efficacy, rated 2.3 out of 10.

It contains 2 active ingredients with proven anti-wrinkle efficacy:

1️⃣ Niacinamide (est. ≈1.5%),
 one of the most effective and well-researched anti-wrinkle ingredients. A clinical study involving 30 participants (Kawada et al.) confirmed that a cream with 4% niacinamide reduced the average depth of wrinkles around the eyes by 9% after 8 weeks of use, compared to a vehicle (the same formulation without niacinamide).
 
2️⃣ Glycolic Acid (est. ≈0.3%),
 a highly effective ingredient in peelings but with moderate anti-wrinkle efficacy in leave-on skincare products, as supported by a single clinical study. This study, involving 72 participants (Thibault et al.), demonstrated that a lotion with 5% GA reduced the fine wrinkling score by 6% after 34 days of use, compared to a vehicle (the same formulation without GA).
 
Among others, COSRX Refresh AHA BHA Vitamin C (ABC) Daily Toner also contains contains Adenosine and Ascorbyl Glucoside, two ingredients often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of these ingredients provide insufficient evidence of efficacy according to CreamScan Research Evaluation Standards.
 
While this does not categorically rule out the possibility that these ingredients may reduce wrinkles, their 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, these ingredients do not contribute to 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 additional anti-wrinkle effects through its moisturizing action.
 

Please refer to the Ratings section below for details of the anti-wrinkle rating calculation.

🍀 Rich in Skin-Protecting Antioxidants

We estimate that COSRX Refresh AHA BHA Vitamin C (ABC) Daily Toner is rich (> 3%) in antioxidants, specifically Actinidia Chinensis (Kiwi) Fruit Extract (est. ≈80.0%).

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.

🔴 Skin Soothing and Calming Potential

Based on the ingredient list analysis, COSRX Refresh AHA BHA Vitamin C (ABC) Daily Toner is rich (> 5%) in soothing ingredients, particularly Salix Alba (Willow) Bark Water (est. ≈4.0%).

When applied to the skin, compounds of soothing ingredients, such as triglycerides, phospholipids, fatty acids, phenolic compounds, and antioxidants, work together to soothe the skin through various mechanisms: reducing inflammation, promoting wound healing, repairing the skin barrier, and providing antimicrobial and antioxidant activities.

📌 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: COSRX Refresh AHA BHA Vitamin C (ABC) Daily Toner

 
CreamScan AI identified a few things to consider before adding COSRX Refresh AHA BHA Vitamin C (ABC) Daily Toner to your skincare routine:
 

⚠️ May Increase Skin Photosensitivity Due to Glycolic Acid

This product contains glycolic acid, a popular AHA known for its ability to exfoliate and brighten the skin. Its action works by removing dead skin cells, revealing new, more delicate skin that is particularly vulnerable to sun damage.

As a result, using products with glycolic acid, regardless of concentration, may increase the skin's sensitivity, making it more prone to sunburn or irritation when exposed to UV rays.

To counteract this increased sun sensitivity, apply a broad-spectrum sunscreen with at least SPF 30 daily to protect your skin during glycolic acid treatment.

❗️Please always check the manufacturer's instructions for using the product, either on their website or product label.

⚠️ 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 COSRX Refresh AHA BHA Vitamin C (ABC) Daily 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 COSRX Refresh AHA BHA Vitamin C (ABC) Daily Toner

 
Here’s an overview of the pros and cons of COSRX Refresh AHA BHA Vitamin C (ABC) Daily Toner to help you decide if it’s the right choice for your skincare routine:

⭕ Cons: 

⚠️ May increase skin photosensitivity due to glycolic acid
⚠️ Only if used as a standalone moisturizer - it needs to be paired with occlusives to seal in humectants

Water
Est. %0.3
Function
Origin
WaterThe most used ingredient in skincare. Its concentration defines the product texture: rich creams may have about 50% of water while a light jelly about 90%. Water doesn’t moisturize the skin by itself and is used in skincare as a solvent for other ingredients.
Glycolic Acid
Est. %0.3
Function
Origin
Glycolic Acid

The second most used AHA (after lactic acid) known for its potent exfoliating and smoothing effects. It increases skin cell turnover, which is beneficial for treating acne. When used in peels, glycolic acid has confirmed anti-wrinkle efficacy, though it is less effective in leave-on products like creams and serums.

Allantoin
Est. %0.3
Function
Origin
AllantoinA fluffy, white powder that acts as a humectant due to its water-loving chemistry and as an exfoliant that helps to remove dead skin cells. It has also been shown to be very soothing to irritated and inflamed skin.
