Review

Results you may expect from using La Prairie Platinum Rare Cellular Night Elixir:

Based on the ingredient analysis by CreamScan, these are the key benefits you can expect from using La Prairie Platinum Rare Cellular Night Elixir:

  • Moderate moisturizing. It has a moisturizing rating of 5.2 out of 10.
  • Some anti-wrinkle efficacy: La Prairie Platinum Rare Cellular Night Elixir has an anti-wrinkle rating of 2.1 out of 10 so you may expect some, although limited, effect on wrinkles.
  • Antioxidant protection.

How moisturizing is it?

Quite moisturizing: La Prairie Platinum Rare Cellular Night Elixir has a moisturizing rating of 5.2 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 maximum humectancy of 10 out of 10, primarily due to the high content of Glycerin (est. ≈6.0%) and Butylene Glycol (est. ≈4.0%).

Please refer to the Ratings section below for details of the moisturizing rating calculation.

Anti-wrinkle efficacy

According to CreamScan analysis, La Prairie Platinum Rare Cellular Night Elixir has a slight anti-wrinkle rating of 2.1 out of 10.

It contains 2 active ingredients with proven anti-wrinkle efficacy:

  • Ascorbyl Tetraisopalmitate (est. ≈1.3%),
     the only derivative of Ascorbic acid with confirmed anti-wrinkle efficacy. This ingredient has below-average efficacy, proven by one study.
  • Glycolic Acid (est. ≈0.3%),
     highly effective in peelings, yet with below-average anti-wrinkle efficacy when used in leave-on skincare products.
Among others, La Prairie Platinum Rare Cellular Night Elixir also contains some ingredients marketed as effective in reducing wrinkles, specifically Palmitoyl Tripeptide-1, Palmitoyl Tetrapeptide-7, and Lactobacillus Ferment. 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.
 
Moisturizers, when used regularly, are proven to prevent wrinkle formation and even reduce existing wrinkles. Therefore, this product, like any other moisturizer, could deliver additional anti-wrinkle efficacy through its moisturizing action.
 

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

Antioxidant benefits

We estimate that La Prairie Platinum Rare Cellular Night Elixir is rich (> 3%) in antioxidants, specifically Ascorbyl Tetraisopalmitate (est. ≈1.3%), Glycoproteins (est. ≈0.3%), Platinum (est. ≈0.3%), and others.

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.
