Key Benefits of Plexaderm Rapid Reduction Serum

 
These are the key benefits you can expect from using Plexaderm Rapid Reduction Serum:
 

🔵 Lightweight Purely Humectant Moisturizer Well-Suited for Oily Skin

According to CreamScan analysis, Plexaderm Rapid Reduction Serum is lightly moisturizing, with a moisturizing rating of 3.4 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 high humectancy of 6.9 out of 10, primarily due to the high content of Propylene Glycol (est. ≈6.0%).

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

📌 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.

💧 A Humectant Enhancement for Any Skincare Routine

But it’s not limited to oily skin - such a humectant enhancement 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.

📌 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.

Things to Be Aware Of: Plexaderm Rapid Reduction Serum

 
CreamScan identified a few things to consider before adding Plexaderm Rapid Reduction Serum to your skincare routine:
 

⚠️ If It’s Your Only Moisturizer, It Needs to Be Paired with Some Occlusives

While humectants are highly effective at attracting water to the skin, studies (J. N. Kraft, C. W. Lynde) suggest they may not be efficient when used alone.

One major drawback of purely humectant moisturization is that the water attracted by humectants to the upper layers of the skin can evaporate completely into the environment through transepidermal water loss (TEWL). Adding occlusive ingredients helps seal this moisture into the skin and prevent further water loss.

If you’re using Plexaderm Rapid Reduction Serum as your only moisturizer, consider pairing it with one that contains at least some occlusive ingredients, such as oils, butters, or silicones. These work alongside humectants to create a protective barrier, locking in hydration and ensuring longer-lasting moisturization. The amount of occlusive needed depends on your skin type - the drier the skin, the more occlusives it requires.

If this product is used not as a standalone moisturizer but as part of your skincare routine, such as a toner or serum, it should be applied before your main moisturizer (unless it's a sunscreen), which will provide the necessary occlusivity on top of it.

⚠️ Questionable anti-wrinkle efficacy

If one of your main reasons for choosing Plexaderm Rapid Reduction Serum is its potential anti-aging effects, please note that, according to CreamScan analysis, it currently has a zero anti-wrinkle rating.

It contains Acetyl Hexapeptide-8, an ingredient often marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of Acetyl Hexapeptide-8 provide insufficient evidence of its efficacy according to CreamScan Research Evaluation Standards.

While this does not categorically rule out the possibility that Acetyl Hexapeptide-8 may reduce wrinkles, its 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, 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.

Pros & Cons of Plexaderm Rapid Reduction Serum

 
Here’s an overview of the pros and cons of Plexaderm Rapid Reduction Serum to help you decide if it’s the right choice for your skincare routine:
 

🟩 Pros:

✅ When used alone: Provides humectant-rich moisturizing well-suited for oily skin
✅ As part of a routine: A humectant moisturizing enhancement, beneficial for any skin type
✅ Lightweight texture
 

⭕ Cons: 

⚠️ Only if used as a standalone moisturizer - it needs to be paired with occlusives to seal in humectants

Summary: Plexaderm Rapid Reduction Serum

 
Based on the ingredient list analysis, CreamScan AI suggests that Plexaderm Rapid Reduction Serum
, when used alone, delivers lightweight, humectant-rich moisturizing that is well-suited for oily skin. As part of a moisturizing routine, it provides a humectant enhancement, beneficial for all skin types.
 
That said, there are some things about Plexaderm Rapid Reduction Serum worth noting.
 
Looking at its moisturizing profile, we found that it doesn’t contain any occlusive ingredients, potentially allowing the moisture attracted to the skin by humectants to evaporate. Therefore, if it’s used as the only moisturizer in a routine, it’s recommended to pair it with one that contains at least some occlusive ingredients, such as oils, butters, or silicones.
 
If one of your main reasons for considering Plexaderm Rapid Reduction Serum is its potential anti-aging effects, please note that, according to CreamScan analysis, its anti-wrinkle efficacy is questionable. None of the ingredients in this product provide substantial evidence of their anti-wrinkle efficacy according to CreamScan Research Evaluation Standards.

Ingredients explained

Water
Est. %85
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.
Sodium Silicate
Est. %4
Function
Origin
Sodium Silicate
Magnesium Aluminum Silicate
Est. %3
Function
Origin
Magnesium Aluminum SilicateA naturally occurring clay that is hygroscopic, which means that it easily absorbs water. This ingredient is thus commonly used as an absorbent and emulsion stabilizer. It also modifies slip by improving the spreadability of the products it is used in.
Acetyl Hexapeptide-8
Est. %0.3
Function
Origin
Acetyl Hexapeptide-8

A small synthetic peptide that is thought to act similarly to Botox by calming contractions of the facial muscles and reducing expression wrinkles. The effect is only temporary and it does not improve the skin structure in any way.

Hydrolyzed Rice Protein
Est. %0.3
Function
Origin
Hydrolyzed Rice ProteinA protein derived from rice bran with film-forming abilities. It can help increase moisturization in skin.
Soluble Collagen
Est. %0.3
Function
Origin
Soluble CollagenA protein obtained from farm or marine animals. Collagen molecules are too big to penetrate the skin so when they are applied via a skincare product they sit on top of the skin and act as humectant moisturizers.
Cellulose Gum
Est. %0.3
Function
Origin
Cellulose GumA polymer that is derived from its namesake, cellulose, which is plant-based. It has many formula-helper benefits, including thickening and product stabilization.
Xanthan Gum
Est. %0.3
Function
Origin
Xanthan GumA natural multi-functional ingredient that originates from fermented sugars. Xanthan gum acts as a viscosity-building agent to thicken skincare products. It is also an excellent stabilizer and works well to hold other ingredients together.
Titanium Dioxide (CI 77891)
Est. %0.3
Function
Origin
Titanium Dioxide (CI 77891)One of two the most commonly used mineral sunscreens. It can absorb UV light, including UVB – which causes burning, tanning, and even skin cancer. Also used as a colorant, titanium dioxide gives a product a bright white color.
Iron Oxides (CI 77491)
Est. %0.3
Function
Origin
Iron Oxides (CI 77491)A red colorant also known as red iron oxide. This is an EU-approved colorant used in a wide variety of products.
Iron Oxides (CI 77492)
Est. %0.3
Function
Origin
Iron Oxides (CI 77492)Also known as iron (III) oxide, this ingredient is a yellow-colored pigment that can either be derived from minerals or produced synthetically. It adds yellow tones to cosmetic products.
Phenoxyethanol
Est. %0.3
Function
Origin
PhenoxyethanolThe most frequently used preservative in skincare. It is a clear, oil-like liquid synthetic substance that protects products from harmful bacteria and yeast, whilst still leaving skin microflora unharmed. It is confirmed by research to be harmless.
Ethylhexylglycerin
Est. %0.3
Function
Origin
EthylhexylglycerinA preservative booster derived from glycerin. It is commonly paired with other preservatives to improve their efficacy. Ethylhexylglycerin is also a humectant due to its chemical base of glycerin.
