Does Jack Black Brightening Booster Vitamin C Serum work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using Jack Black Brightening Booster Vitamin C Serum:

  • Significant moisturizing. It has a moisturizing rating of 6.1 out of 10.
  • Antioxidant protection.

Lightweight moisturizer perfect for oily to normal skin

According to CreamScan analysis, Jack Black Brightening Booster Vitamin C Serum is highly moisturizing, with a moisturizing rating of 6.1 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 2.7 out of 10 and a very high humectancy of 9.4 out of 10, primarily due to the high content of Propanediol (est. ≈4.0%) and Glycerin (est. ≈3.0%).

This type of moisturizer is ideal for people with 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.

Please refer to the Ratings section below for details of the moisturizing rating calculation.

Questionable anti-wrinkle efficacy

According to CreamScan analysis, Jack Black Brightening Booster Vitamin C Serum has a zero anti-wrinkle rating.

It contains Tetrahexyldecyl Ascorbate and Camellia Sinensis Leaf Extract, 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 generate 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 Jack Black Brightening Booster Vitamin C Serum is rich (> 3%) in antioxidants, specifically Tetrahexyldecyl Ascorbate (est. ≈6.0%).

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.
