Key Benefits of Dermorepubliq 15% L-Ascorbic Acid + E + Ferulic Acid Brightening Formula Serum

 
These are the key benefits you can expect from using Dermorepubliq 15% L-Ascorbic Acid + E + Ferulic Acid Brightening Formula Serum:
 

🔵 Lightweight Humectant Moisturizer Ideal for Oily Skin

According to CreamScan analysis, Dermorepubliq 15% L-Ascorbic Acid + E + Ferulic Acid Brightening Formula Serum is quite moisturizing, with a moisturizing rating of 5.5 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 1.0 out of 10 and a maximum humectancy of 10 out of 10, primarily due to the high content of Propylene Glycol (est. ≈15.1%).

This humectant-rich product, when used alone as a moisturizer, is ideal for oily skin, offering significant hydration in a lightweight, fast-absorbing formula with a minimal amount of occlusive ingredients.

It’s also a great choice for people with normal skin who prefer lightweight moisturizers.

💧 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, Dermorepubliq 15% L-Ascorbic Acid + E + Ferulic Acid Brightening Formula Serum has a modest level of anti-wrinkle efficacy, rated 2.5 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Ascorbic Acid (est. ≈15.0%),
 or Vitamin C, a popular ingredient, yet with moderate anti-wrinkle efficacy, as confirmed by a single clinical study involving 20 participants (Humbert et al.). This study showed that a cream with a relatively high concentration of 5% ascorbic acid reduced the average wrinkle depth by 7% after 6 months of use, compared to a vehicle (the same formulation without ascorbic acid).
 
Among others, Dermorepubliq 15% L-Ascorbic Acid + E + Ferulic Acid Brightening Formula Serum also contains Snail Secretion Filtrate, an ingredient often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Snail Secretion Filtrate provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards.
 
While this does not categorically rule out the possibility that Snail Secretion Filtrate 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 Dermorepubliq 15% L-Ascorbic Acid + E + Ferulic Acid Brightening Formula Serum is rich (> 3%) in antioxidants, specifically Ascorbic Acid (est. ≈15.0%) and Tocopherol (est. ≈2.0%).

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 model to incorporate anti-pigmentation, exfoliation and anti-acne ratings.
