Key Benefits of Rhonda Allison Amino Peptide Serum

 
These are the key benefits you can expect from using Rhonda Allison Amino Peptide Serum:
 

🔵 Lightweight Purely Humectant Moisturizing, Ideal for Oily Skin

According to CreamScan analysis, Rhonda Allison Amino Peptide 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 Aloe Barbadensis Leaf Extract (est. ≈90.0%).

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.

📌 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 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, Rhonda Allison Amino Peptide Serum has a slight anti-wrinkle rating of 0.1 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Ascorbic Acid (est. ≈0.3%),
 or Vitamin C, a popular ingredient, yet with moderate anti-wrinkle efficacy, as confirmed by a single clinical study involving 20 participants (Humbert et al.). This study showed that a cream with a relatively high concentration of 5% ascorbic acid reduced the average wrinkle depth by 7% after 6 months of use, compared to a vehicle (the same formulation without ascorbic acid).
 
Among others, Rhonda Allison Amino Peptide Serum also contains some ingredients marketed often as effective in reducing wrinkles, specifically Acetyl Hexapeptide-8, Palmitoyl Tripeptide-5, and Retinyl Palmitate. 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.

🍀 Rich in Skin-Protecting Antioxidants

We estimate that Rhonda Allison Amino Peptide Serum is rich (> 3%) in antioxidants, specifically Aloe Barbadensis Leaf Extract (est. ≈90.0%).

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.

🔴 Skin Soothing and Calming Potential

Based on the ingredient list analysis, Rhonda Allison Amino Peptide Serum is rich (> 5%) in soothing ingredients, particularly Aloe Barbadensis Leaf Extract (est. ≈90.0%).

When applied to the skin, compounds of soothing ingredients, such as triglycerides, phospholipids, fatty acids, phenolic compounds, and antioxidants, work together to soothe the skin through various mechanisms: reducing inflammation, promoting wound healing, repairing the skin barrier, and providing antimicrobial and antioxidant activities.

📌 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: Rhonda Allison Amino Peptide Serum

 
CreamScan identified a few things to consider before adding Rhonda Allison Amino Peptide 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 Rhonda Allison Amino Peptide 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.

Pros & Cons of Rhonda Allison Amino Peptide Serum

 
Here’s an overview of the pros and cons of Rhonda Allison Amino Peptide Serum to help you decide if it’s the right choice for your skincare routine:
 

🟩 Pros:

✅ When used alone: Provides humectant-rich moisturizing ideal for oily skin
✅ As part of a routine: A humectant moisturizing boost, beneficial for any skin type
✅ Lightweight texture
Provides slight anti-wrinkle efficacy
✅ Rich in antioxidants that combat oxidative stress associated with accelerated skin aging and defend against environmental damage
✅ Potentially soothing, as it contains a high concentration of soothing ingredients, specifically Aloe Barbadensis Leaf Extract
 

⭕ Cons: 

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

Summary: Rhonda Allison Amino Peptide Serum

, when used alone, delivers lightweight, humectant-rich moisturizing, making it ideal for oily skin. As part of a moisturizing routine, it provides a humectant boost, beneficial for all skin types.
 
Rhonda Allison Amino Peptide Serum contains ingredients with proven evidence of anti-wrinkle efficacy that may offer a slight anti-wrinkle effect. As a result, you can expect a positive, though relatively minimal, impact on wrinkles.
