Key Benefits of Radiant Seoul Bright Potion Night Power Serum

 
These are the key benefits you can expect from using Radiant Seoul Bright Potion Night Power Serum:
 

🔵 Lightweight Moisturizer Perfect for Combination and Oily Skin

According to CreamScan analysis, Radiant Seoul Bright Potion Night Power Serum is highly moisturizing, with a moisturizing rating of 6.8 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 Butylene Glycol (est. ≈6.0%) and Glycerin (est. ≈2.0%), and a moderate occlusivity of 3.6 out of 10, mainly due to the high content of Butylene Glycol Dicaprylate/Dicaprate (est. ≈4.0%) and Dimethicone (est. ≈3.0%).

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.

🟣🟣 Considerable Anti-Wrinkle Efficacy

According to CreamScan analysis, Radiant Seoul Bright Potion Night Power Serum has a moderate anti-wrinkle rating of 4.0 out of 10.

It contains 2 active ingredients with proven anti-wrinkle efficacy:

1️⃣ 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).
 
2️⃣ Niacinamide (est. ≈1.0%),
 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, Radiant Seoul Bright Potion Night Power Serum also contains contains Acetyl Glucosamine and Beta-Glucan, 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.
 
While this does not categorically rule out the possibility that these ingredients may reduce wrinkles, their 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, 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 additional anti-wrinkle effects through its moisturizing action.
 

Please refer to the Ratings section below for details of the anti-wrinkle rating calculation.

📌 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.

Things to Be Aware Of: Radiant Seoul Bright Potion Night Power Serum

 
CreamScan identified a few things to consider before adding Radiant Seoul Bright Potion Night Power Serum to your skincare routine:
 

⚠️ May Increase Skin Photosensitivity Due to Retinol and Glycolic Acid

This product contains both retinol and glycolic acid, two potent skincare ingredients with complementary benefits. Retinol offers powerful anti-wrinkle properties by boosting cell turnover, while glycolic acid, a popular AHA, exfoliates the skin by removing dead skin cells. Together, they reveal new, more delicate skin that is brighter and smoother but also more vulnerable to sun damage.

Using products with both retinol and glycolic acid may increase the skin’s sensitivity, making it more prone to sunburn or irritation when exposed to UV rays.

To protect your skin, dermatologists recommend applying a broad-spectrum sunscreen with at least SPF 30 daily throughout the use of these ingredients and avoiding direct sun exposure. Retinol should be applied at night, as it is sensitive to sunlight and can lose its potency when exposed to UV rays.

📌 Please always check the manufacturer's instructions for using products containing retinol and glycolic acid, either on their website or product label.
