Key Benefits of Dewyer Shroom Serum

 
These are the key benefits you can expect from using Dewyer Shroom Serum:
 

🔵 Lightweight Purely Humectant Moisturizing, Ideal for Oily Skin

According to CreamScan analysis, Dewyer Shroom Serum 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%), Camellia Sinensis Leaf Extract (est. ≈4.0%) and Betaine (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.

🟣 Modest Anti-Wrinkle Efficacy

According to CreamScan analysis, Dewyer Shroom Serum has a modest level of anti-wrinkle efficacy, rated 2.5 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Retinol (est. ≈0.1%),
 the most effective non-prescription anti-wrinkle ingredient. Numerous clinical studies have shown its positive effects at concentrations as low as 0.1%. A study with 36 participants (Kafi et al.) confirmed that a lotion containing 0.4% retinol reduced wrinkle severity by 21% after 24 weeks of use, compared to the same formulation without retinol (vehicle).
 
Among others, Dewyer Shroom Serum 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.
 
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 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 Dewyer Shroom Serum is rich (> 3%) in antioxidants, specifically Camellia Sinensis Leaf 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.

🔴 Skin Soothing and Calming Potential

Based on the ingredient list analysis, Dewyer Shroom Serum is rich (> 5%) in soothing ingredients, particularly Camellia Sinensis Leaf Extract (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: Dewyer Shroom Serum

 
CreamScan AI identified a few things to consider before adding Dewyer Shroom Serum to your skincare routine:
 

⚠️ May Increase Skin Photosensitivity Due to Retinol

This product contains retinol, which offers powerful anti-wrinkle benefits. The mechanism behind retinol’s action is boosting cell turnover. This process exposes new, more delicate skin, making it more vulnerable to sun damage.

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

To protect the skin, dermatologists recommend applying a broad-spectrum sunscreen with at least SPF 30 throughout the duration of retinol treatment, along with avoiding direct sun exposure. Retinol should be used at night, as it is sensitive to sunlight and can lose its potency when exposed to UV rays.

📌 Please always check the manufacturer's instructions for using the retinol-containing products, 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 Dewyer Shroom Serum 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.

Summary: Dewyer Shroom Serum

 
Based on the ingredient list analysis, CreamScan AI suggests that Dewyer Shroom Serum
, 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.
 
Dewyer Shroom Serum contains ingredients with proven evidence of anti-wrinkle efficacy that may provide a modest anti-wrinkle effect. As a result, you can expect a positive, though not very significant, impact on wrinkles.
 
Rich in antioxidants, Dewyer Shroom Serum helps protect against free radical damage and offers multiple benefits for all skin types, including preventing premature aging, defending against environmental damage, and calming inflammation. This product is also formulated with a high concentration of soothing ingredients, offering the potential to calm and comfort irritated skin. Whether you’re experiencing redness, irritation, or general sensitivity, its soothing properties may help restore balance and provide relief.
 
That said, there are some things about Dewyer Shroom Serum 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.
 
This product contains retinol, the most powerful and well-researched non-prescription anti-wrinkle ingredient. However, retinol can make your skin more prone to sun damage and increase sensitivity, so it’s recommended to use a broad-spectrum sunscreen with at least SPF 30 throughout the duration of retinol treatment.
