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

According to CreamScan analysis, Olay Regenerist Vitamin C + Peptide 24 MAX Hydrating Moisturizer is quite moisturizing, with a moisturizing rating of 5.9 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 1.8 out of 10 and a maximum humectancy of 10 out of 10, primarily due to the high content of Glycerin (est. ≈9.0%), Niacinamide (est. ≈4.0%) and Lactic Acid (est. ≈2.5%).

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.

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.

Significant anti-wrinkle efficacy

According to CreamScan analysis, Olay Regenerist Vitamin C + Peptide 24 MAX Hydrating Moisturizer has a high anti-wrinkle rating of 6.0 out of 10.

It contains one ingredient with proven anti-wrinkle efficacy: Niacinamide (est. ≈4.0%), 
 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 Regenerist Vitamin C + Peptide 24 MAX Hydrating Moisturizer 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. Therefore, these ingredients do not contribute to the anti-wrinkle rating.
 

Please refer to the Ratings section below for details of the anti-wrinkle rating calculation.

Rich in skin-protecting antioxidants

We estimate that Olay Regenerist Vitamin C + Peptide 24 MAX Hydrating Moisturizer is rich (> 3%) in antioxidants, specifically Niacinamide (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.
