  • Moderate moisturizing. It has a moisturizing rating of 5.4 out of 10.

Key Benefits of OAM Vitamin C Radiance Moisturizer

 
These are the key benefits you can expect from using OAM Vitamin C Radiance Moisturizer:
 

Lightweight Moisturizer Perfect for Combination and Oily Skin

According to CreamScan analysis, OAM Vitamin C Radiance Moisturizer is quite moisturizing, with a moisturizing rating of 5.4 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 2.6 out of 10 and a very high humectancy of 8.3 out of 10, primarily due to the high content of Glycerin (est. ≈4.0%) and Sodium PCA (est. ≈2.5%).

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, OAM Vitamin C Radiance Moisturizer has a modest level of anti-wrinkle efficacy, rated 3.6 out of 10.

It contains 4 active ingredients 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).
  • Ascorbyl Tetraisopalmitate (est. ≈0.3%),
     the only derivative of ascorbic acid with solid evidence of anti-wrinkle efficacy. A single clinical study involving 23 participants (Mariko et al.) demonstrated that a cream with 1% ATIP reduced the average depth of periorbital wrinkles by 6% after 8 weeks of use, compared to a vehicle (the same formulation without ATIP).
  • Niacinamide (est. ≈0.3%),
     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).
  • Ascorbic Acid (est. ≈0.3%),
     or Vitamin C, a popular ingredient, yet with moderate anti-wrinkle efficacy, as confirmed by a single clinical study involving 20 participants (Humbert et al.). This study showed that a cream with a relatively high concentration of 5% ascorbic acid reduced the average wrinkle depth by 7% after 6 months of use, compared to a vehicle (the same formulation without ascorbic acid).
Among others, OAM Vitamin C Radiance Moisturizer also contains some ingredients often marketed as effective in reducing wrinkles, specifically Sodium Ascorbyl Phosphate, Caffeine, Malus Domestica Fruit Cell Culture Extract, and Tetrapeptide-21. 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 OAM Vitamin C Radiance Moisturizer is rich (> 3%) in antioxidants, specifically Sodium Ascorbyl Phosphate (est. ≈1.0%), Ascorbyl Tetraisopalmitate (est. ≈0.3%), Ascorbic Acid (est. ≈0.3%), and others.

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.

Lecithin
Est. %0.3
Function
Origin
LecithinA humectant, emollient, and emulsifier best suited for water-in-oil emulsions. Lecithin can come from sunflowers, soy, and eggs. The downside to lecithin is that it causes an extra burden on the formula’s preservative because it is nutritious.

Butylene Glycol
Est. %0.3
Function
Origin
Butylene Glycol
