Does Q + A Zinc PCA Facial Serum work?

Based on the ingredient list analysis by CreamScan AI, these are the key benefits you can expect from using Q + A Zinc PCA Facial Serum:

  • Strong humectant moisturizing. This lightweight, humectant-rich product, ideal for oily skin, has a moisturizing rating of 5.0 out of 10.
  • Antioxidant protection.

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

According to CreamScan analysis, Q + A Zinc PCA Facial Serum is quite moisturizing, with a moisturizing rating of 5.0 out of 10.

Is it more humectant or occlusive? It is purely humectant. It has zero occlusivity (we didn't find any occlusive ingredients on the ingredient list) and a maximum humectancy of 10 out of 10, primarily due to the high content of Propylene Glycol (est. ≈6.0%), Betaine (est. ≈3.0%) and Pentylene Glycol (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.

Questionable anti-wrinkle efficacy

According to CreamScan analysis, Q + A Zinc PCA Facial Serum has a zero anti-wrinkle rating.

It contains Lactobacillus Ferment, an ingredient often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Lactobacillus Ferment provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards. Therefore, this ingredient does 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 Q + A Zinc PCA Facial Serum is rich (> 3%) in antioxidants, specifically Lactobacillus (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.

Ingredients explained

Water
Est. %80
Function
Origin
WaterThe most used ingredient in skincare. Its concentration defines the product texture: rich creams may have about 50% of water while a light jelly about 90%. Water doesn’t moisturize the skin by itself and is used in skincare as a solvent for other ingredients.
Propylene Glycol
Est. %6
Function
Origin
Propylene GlycolA clear, thick, odorless liquid of synthetic origin. Its main function is to stabilize cosmetic products exposed to varying temperatures. It is also a moderately strong humectant with similar properties to glycerin.
Lactobacillus
Est. %4
Function
Origin
LactobacillusA genus of probiotic bacteria. Lactobacillus bacteria are part of the human microflora and their ferment products contain antioxidants.
Betaine
Est. %3
Function
Origin
BetaineAn ingredient derived from the sucrose in sugar beets. It has a negative chemical charge and a positive chemical charge on the same molecule. This allows betaine to be hygroscopic or humectant and thus provide moisturization by drawing water to the skin.
Pentylene Glycol
Est. %2
Function
Origin
Pentylene Glycol

A naturally or synthetically derived preservative that exhibits effective antifungal and antibacterial traits. It also acts as a booster for more traditional preservatives. Pentylene glycol can also serve as a moisturizing humectant and solvent.

Zinc PCA
Est. %1.5
Function
Origin
Zinc PCAA two-part ingredient: Zinc helps to control sebum and bacteria in acne-prone skin, while skin-identical PCA is a moisturizing humectant. Zinc PCA may even boost collagen production and so is researched as a potential anti-wrinkle ingredient.
Lactobacillus Ferment
Est. %1.3
Function
Origin
Lactobacillus FermentA biotechnological product – a mixture of metabolic products of Lactobacillus culture. Some Lactobacillus forms have been reported to have anti-wrinkle and barrier repairing effects, as well as able to improve skin hydration, elasticity, and gloss.
