Key Benefits of Josh Rosebrook Daily Acid Toner

 
These are the key benefits you can expect from using Josh Rosebrook Daily Acid Toner:
 

Lightweight Purely Humectant Moisturizing, Ideal for Oily Skin

According to CreamScan analysis, Josh Rosebrook Daily Acid 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 Aloe Barbadensis Leaf Juice (est. ≈75.0%) and Glycerin (est. ≈6.0%).

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.

Tip: 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.

Slight Anti-Wrinkle Efficacy

According to CreamScan analysis, Josh Rosebrook Daily Acid Toner has a slight anti-wrinkle rating of 0.1 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: 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, Josh Rosebrook Daily Acid Toner also 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. Therefore, this ingredient does 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 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 Josh Rosebrook Daily Acid Toner is rich (> 3%) in antioxidants, specifically Aloe Barbadensis Leaf Juice (est. ≈75.0%).

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, Josh Rosebrook Daily Acid Toner is rich (> 5%) in soothing ingredients, particularly Aloe Barbadensis Leaf Juice (est. ≈75.0%).

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: Josh Rosebrook Daily Acid Toner

 
CreamScan AI identified a few things to consider before adding Josh Rosebrook Daily Acid 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 Josh Rosebrook Daily Acid 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.
