"Clarins - Duo Double Serum" is effective for: Moisturizing
Ingredient callouts
- This product also contains Vitamin C (Ascorbic Acid). It can be an effective active for anti-aging and evening out the skin tone, but in this product it is used for stabilizing other ingredients in the formulation. In this concentration (0.20% - 0.35%) it cannot have a noticeable benefit for the skin.
- Ceramides (salicyloyl phytosphingosine 0.20% - 0.35%). Ceramides are an important part of our natural skin barrier. The Ceramides used in skincare are synthetic or come from plants. They help soften the skin and can help "fill the gaps" in the skin barrier, keeping the skin hydrated and resilient for longer.
- Humectants (glycerin 0.25% - 0.45%, salicyloyl phytosphingosine 0.20% - 0.35% and glycerin 4.00% - 4.90%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

This product can help improve hydration of the skin with the two types of ingredients.
The first type is called “humectants”:
these ingredients help attract water.
When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from
within deeper layers of the skin. The following ingredients in this product do the job:
glycerin, butylene glycol.
This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: caprylic/capric triglyceride, squalane.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: salicyloyl phytosphingosine
