Does PCA SKIN Rejuvenating Serum Work?

 
According to CreamScan's analysis of the ingredient list, here’s what PCA SKIN Rejuvenating Serum has to offer:
 
Moderate moisturizing. It has a moisturizing rating of 4.5 out of 10.
✅ Slight anti-wrinkle effect: PCA SKIN Rejuvenating Serum has an anti-wrinkle rating of 0.4 out of 10, so you may expect a positive, although insignificant, effect on wrinkles.

  

Key Benefits of PCA SKIN Rejuvenating Serum

 
These are the key benefits you can expect from using PCA SKIN Rejuvenating Serum:
 

🔵 Lightweight Humectant Moisturizer Ideal for Oily Skin

According to CreamScan analysis, PCA SKIN Rejuvenating Serum is quite moisturizing, with a moisturizing rating of 4.5 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 0.4 out of 10 and a very high humectancy of 8.6 out of 10, primarily due to the high content of Glycerin (est. ≈4.0%).

This humectant-rich product, when used alone as a moisturizer, is ideal for oily skin, offering significant hydration in a lightweight, fast-absorbing formula with a minimal amount of occlusive ingredients.

It’s also a great choice for people with normal skin who prefer lightweight moisturizers.

💧 A Humectant Boost for Any Skincare Routine

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.

🟣 Slight Anti-Wrinkle Efficacy

According to CreamScan analysis, PCA SKIN Rejuvenating Serum has a slight anti-wrinkle rating of 0.4 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: 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).
 
Among others, PCA SKIN Rejuvenating Serum also contains some ingredients marketed often as effective in reducing wrinkles, specifically Gluconolactone, Camellia Sinensis Leaf Extract, and sh-Oligopeptide-1. 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.
