Key Benefits of Alastin C-Radical Defense Antioxidant Serum

 
These are the key benefits you can expect from using Alastin C-Radical Defense Antioxidant Serum:
 

Lightweight Moisturizer Well-Suited for Combination and Oily Skin

According to CreamScan analysis, Alastin C-Radical Defense Antioxidant Serum is quite moisturizing, with a moisturizing rating of 5.2 out of 10.

Is it more humectant or occlusive? Rather humectant. It has a high humectancy of 6.7 out of 10, primarily due to the substantial concentration of Glycerin (est. ≈4.0%), and a moderate occlusivity of 3.6 out of 10, mainly due to the significant content of Caprylic/Capric Triglyceride (est. ≈6.0%).

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

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

A Humectant Enhancement for Any Skincare Routine

But it’s not limited to combination and oily skin - such a humectant enhancement 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.

Slight Anti-Wrinkle Efficacy

According to CreamScan analysis, Alastin C-Radical Defense Antioxidant Serum has a slight anti-wrinkle rating of 1.9 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Ectoin (est. ≈1.5%), 
 an amino acid-derived ingredient with moderate but proven anti-wrinkle efficacy.  A single clinical study involving 104 participants (Heinrich et al.) confirmed that a cream containing 2% ectoin reduced the average wrinkle width by 7% after 4 weeks of use, compared to the same formulation without ectoin (vehicle).
 
Among others, Alastin C-Radical Defense Antioxidant Serum also contains some ingredients often marketed as effective in reducing wrinkles, specifically Sodium Ascorbate, Ubiquinone, Centella Asiatica Extract, Olea Europaea (Olive) Leaf Extract, and Camellia Sinensis Leaf Extract. 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 Alastin C-Radical Defense Antioxidant Serum is rich (> 3%) in antioxidants, specifically Sodium Ascorbate (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.

Things to Be Aware Of: Alastin C-Radical Defense Antioxidant Serum

 
CreamScan AI identified a few things to consider before adding Alastin C-Radical Defense Antioxidant Serum to your skincare routine:
 

If It’s an Exfoliator, It May Increase Skin Photosensitivity Due to Lactic Acid

This product contains lactic acid, a popular AHA known for its ability to gently exfoliate and brighten the skin. It works by removing dead skin cells, revealing new, more delicate skin that is more vulnerable to sun damage.

In smaller quantities, lactic acid is often used as a pH adjuster and may not significantly contribute to exfoliation. However, at higher concentrations, it functions as an effective exfoliant with benefits and risks similar to other AHAs. Products with AHAs, including lactic acid, may increase skin sensitivity, making it more prone to sunburn or irritation when exposed to UV rays.

If this product is designed for exfoliation, applying a broad-spectrum sunscreen with at least SPF 30 daily is essential to protect your skin. Always check the label or the manufacturer’s website for specific usage instructions.
