Key Benefits of Olay Vitamin C + Peptide 24 MAX Brightening Serum

 
These are the key benefits you can expect from using Olay Vitamin C + Peptide 24 MAX Brightening Serum:
 

🔵 Lightweight Moisturizer Perfect for Combination and Oily Skin

According to CreamScan analysis, Olay Vitamin C + Peptide 24 MAX Brightening Serum is highly moisturizing, with a moisturizing rating of 6.0 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 2.0 out of 10 and a maximum humectancy of 10 out of 10, primarily due to the high content of Glycerin (est. ≈6.0%), Niacinamide (est. ≈3.0%) and Lactic Acid (est. ≈2.0%).

This type of moisturizer is ideal for people with combination and 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.

💧 A Humectant Boost for Any Skincare Routine

But it’s not limited to combination and 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.

🟣🟣 Considerable Anti-Wrinkle Efficacy

According to CreamScan analysis, Olay Vitamin C + Peptide 24 MAX Brightening Serum has a moderate anti-wrinkle rating of 4.5 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Niacinamide (est. ≈3.0%),
 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, Olay Vitamin C + Peptide 24 MAX Brightening Serum also contains contains 3-O-Ethyl Ascorbic Acid and Palmitoyl Pentapeptide-4, 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.
 
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 Olay Vitamin C + Peptide 24 MAX Brightening Serum is rich (> 3%) in antioxidants, specifically Niacinamide (est. ≈3.0%).

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.

📌 Please note that this is not a complete list of benefits. We are in the process of enhancing our AI model to incorporate anti-pigmentation, exfoliation and anti-acne ratings.

Things to Be Aware Of: Olay Vitamin C + Peptide 24 MAX Brightening Serum

 
CreamScan AI identified a few things to consider before adding Olay Vitamin C + Peptide 24 MAX Brightening Serum to your skincare routine:
 

⚠️ If It’s an Exfoliator, It May Increase Skin Photosensitivity Due to Lactic Acid

This product contains lactic acid, a popular AHA known for its ability to gently exfoliate and brighten the skin. It works by removing dead skin cells, revealing new, more delicate skin that is more vulnerable to sun damage.

In smaller quantities, lactic acid is often used as a pH adjuster and may not significantly contribute to exfoliation. However, at higher concentrations, it functions as an effective exfoliant with benefits and risks similar to other AHAs. Products with AHAs, including lactic acid, may increase skin sensitivity, making it more prone to sunburn or irritation when exposed to UV rays.

If this product is designed for exfoliation, applying a broad-spectrum sunscreen with at least SPF 30 daily is essential to protect your skin. Always check the label or the manufacturer’s website for specific usage instructions.
