Does Doa Kozmetik Vitamin C 16% Mix Serum work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using Doa Kozmetik Vitamin C 16% Mix Serum:

  • Moderate moisturizing. It has a moisturizing rating of 4.4 out of 10.
  • Some anti-wrinkle efficacy: Doa Kozmetik Vitamin C 16% Mix Serum has an anti-wrinkle rating of 2.2 out of 10 so you may expect some, although limited, effect on wrinkles.
  • Antioxidant protection.

Lightweight moisturizer ideal for oily skin and a humectant boost for any skincare routine

According to CreamScan analysis, Doa Kozmetik Vitamin C 16% Mix Serum is quite moisturizing, with a moisturizing rating of 4.4 out of 10.

Is it more humectant or occlusive? Purely humectant. It has zero occlusivity (we didn't find any occlusive ingredients on the ingredient list) and a very high humectancy of 8.7 out of 10, primarily due to the high content of Sodium Lactate (est. ≈3.0%) and Sodium PCA (est. ≈2.0%).

This humectant-rich product, when used alone as a moisturizer, is ideal for oily skin, providing significant hydration in a lightweight, fast-absorbing formula without any occlusive ingredients.

Tip: Certain studies suggest that humectants alone may not effectively moisturize the skin. If you use this product as your only moisturizer, we recommend following it with one that contains at least some occlusive ingredients.

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.

Some anti-wrinkle efficacy

According to CreamScan analysis, Doa Kozmetik Vitamin C 16% Mix Serum has a slight anti-wrinkle rating of 2.2 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Niacinamide (est. ≈1.5%), 
 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, Doa Kozmetik Vitamin C 16% Mix Serum also contains contains 3-O-Ethyl Ascorbic Acid and Sodium Ascorbyl Phosphate, 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.

Rich in skin-protecting antioxidants

We estimate that Doa Kozmetik Vitamin C 16% Mix Serum is rich (> 3%) in antioxidants, specifically 3-O-Ethyl Ascorbic Acid (est. ≈6.0%) and Sodium Ascorbyl Phosphate (est. ≈4.0%).

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.
