MoisturizingAcetyl dipeptide-1 cetyl ester, Butyrospermum parkii butter + 8 moreStrong evidence
“A moisturizing cream for moisturized and sensitive skin that supports the barrier function of the skin and protects the skin from dryness.”
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: butyrospermum parkii butter, squalane.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl dipeptide-1 cetyl ester
Anti-agingNot advertised by the brand · Acetyl dipeptide-1 cetyl ester, Butyrospermum parkii butterModerate evidence
This product contains acetyl dipeptide-1 cetyl ester. This ingredient might be able to help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness, but there is not enough evidence that it actually works.

Product summary
Based on the ingredients included, "La Roche-Posay - Toleriane Dermallergo Light Cream" works well for moisturizing the skin. As we expect from a proper moisturizer, the formula includes a combo of effective humectants and emollients. These are the two different types of ingredients that are essential for improving the skin hydration and supporting a healthy skin barrier. Glycerin, butylene glycol and caprylyl glycol in this product (humectants) attract water molecules to the upper layer of the skin (the water comes from the outside air or from the deeper layers of the skin if the air is dry). Isocetyl stearate, butyrospermum parkii butter, squalane, cetyl alcohol and caprylyl glycol in this product help decrease the water evoporation from the skin, so that it stays hydrated for longer. These ingredients also soften the skin and take away the feeling of tightness and dryness.
Ingredient callouts
- We like that this moisturizer contains peptides (acetyl dipeptide-1 cetyl ester 0.15% - 0.25%). There are many different kind of Peptides and they are naturally present in our skin. They all are a combination of aminoacids. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The science is still not settled on how effective Peptides are in skincare, but it is very likely that they have a benefit. Peptides might help restore the skin barrier and fight the signs of aging. At the very least, Peptides work as humectants: they attract water to the upper layer of the skin and improve its hydration.
