Key Benefits of Biossance Squalane + 10% Vitamin C Dark Spot Serum

 
These are the key benefits you can expect from using Biossance Squalane + 10% Vitamin C Dark Spot Serum:
 

🔵 Lightweight Humectant Moisturizer Ideal for Oily Skin

According to CreamScan analysis, Biossance Squalane + 10% Vitamin C Dark Spot Serum is quite moisturizing, with a moisturizing rating of 5.8 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 1.5 out of 10 and a maximum humectancy of 10 out of 10, primarily due to the high content of Glycerin (est. ≈10.1%).

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.

🍀 Rich in Skin-Protecting Antioxidants

We estimate that Biossance Squalane + 10% Vitamin C Dark Spot Serum is rich (> 3%) in antioxidants, specifically 3-O-Ethyl Ascorbic Acid (est. ≈10.0%).

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

Things to Be Aware Of: Biossance Squalane + 10% Vitamin C Dark Spot Serum

 
CreamScan AI identified a few things to consider before adding Biossance Squalane + 10% Vitamin C Dark Spot Serum to your skincare routine:
 

⚠️ Questionable anti-wrinkle efficacy

If one of your main reasons for choosing Biossance Squalane + 10% Vitamin C Dark Spot Serum is its potential anti-aging effects, please note that, according to CreamScan analysis, it currently has a zero anti-wrinkle rating.

It contains 3-O-Ethyl Ascorbic Acid, an ingredient often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of 3-O-Ethyl Ascorbic Acid provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards.

While this does not categorically rule out the possibility that 3-O-Ethyl Ascorbic Acid 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.
