  • Significant moisturizing. It has a moisturizing rating of 6.6 out of 10.

Key Benefits of OSEA Anti-Aging Sea Serum

 
These are the key benefits you can expect from using OSEA Anti-Aging Sea Serum:
 

Lightweight Moisturizer Perfect for Combination and Oily Skin

According to CreamScan analysis, OSEA Anti-Aging Sea Serum is highly moisturizing, with a moisturizing rating of 6.6 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a maximum humectancy of 10 out of 10, primarily due to the substantial concentration of Propanediol (est. ≈4.0%) and Glycerin (est. ≈3.0%), and a moderate occlusivity of 3.2 out of 10, mainly due to the high content of Simmondsia Chinensis (Jojoba) Seed Oil (est. ≈6.0%).

This type of moisturizer is ideal for people with combination and oily skin who want maximum hydration in a relatively lightweight, non-greasy formula. It combines a significant amount of humectants with a limited amount of occlusive ingredients to boost moisturizing efficacy without feeling too heavy.

This product may also be a good choice for people with normal skin who prefer fast-absorbing textures, as it balances significant moisturizing potential with a relatively lightweight texture.

A Humectant Boost for Any Skincare Routine

But it’s not limited to combination and 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, OSEA Anti-Aging Sea Serum has a modest level of anti-wrinkle efficacy, rated 3.0 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Niacinamide (est. ≈2.0%), 
 one of the most effective and well-researched anti-wrinkle ingredients. A clinical study involving 30 participants (Kawada et al.) confirmed that a cream with 4% niacinamide reduced the average depth of wrinkles around the eyes by 9% after 8 weeks of use, compared to a vehicle (the same formulation without niacinamide).
 
Among others, OSEA Anti-Aging Sea Serum also 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. 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 OSEA Anti-Aging Sea Serum is rich (> 3%) in antioxidants, specifically Niacinamide (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 AI model to incorporate anti-pigmentation, exfoliation and anti-acne ratings.
