Key Benefits of Maritime Naturals Advanced Smoothing Retinol Serum

 
These are the key benefits you can expect from using Maritime Naturals Advanced Smoothing Retinol Serum:
 

Lightweight Humectant Moisturizer Ideal for Oily Skin

According to CreamScan analysis, Maritime Naturals Advanced Smoothing Retinol Serum is quite moisturizing, with a moisturizing rating of 5.2 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 0.6 out of 10 and a very high humectancy of 9.9 out of 10, primarily due to the high content of Aloe Barbadensis Leaf Extract (est. ≈6.0%) and Glycerin (est. ≈3.0%).

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, Maritime Naturals Advanced Smoothing Retinol 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, Maritime Naturals Advanced Smoothing Retinol Serum also contains contains Centella Asiatica Leaf Extract and Camellia Sinensis Leaf Extract, 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. 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 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 Maritime Naturals Advanced Smoothing Retinol Serum is rich (> 3%) in antioxidants, specifically Aloe Barbadensis Leaf Extract (est. ≈6.0%).

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, Maritime Naturals Advanced Smoothing Retinol Serum is rich (> 5%) in soothing ingredients, particularly Hamamelis Virginiana (Witch Hazel) Water (est. ≈75.0%) and Aloe Barbadensis Leaf Extract (est. ≈6.0%).

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.
