Product Summary
Judging from the ingredient list, "La Roche-Posay - Substiane Eyes" works well for improving skin hydration To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. La Roche-Posay - Substiane Eyes ticks this box. Humectants in this product (arginine pca, glycerin, bis-peg-18 methyl ether dimethyl silane and propylene glycol) help to increase the water content in the upper layer of the skin. (These ingredients do so by "capturing" water molecules from the outside air or from within the deeper layers of the skin). Prunus armeniaca kernel oil, beeswax, butyrospermum parkii butter, cera alba and dimethicone 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.
Irritation risk
This formulation includes some common irritants, including ingredients that do not provide a benefit for the skin. We assess the overall irritancy of this moisturizer to be low. For a detailed overview of all potential irritants: click here

Works for
Anti-oxidation
This product contains antioxidants (arginine pca) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).
An amino-acid. Helps attract water to the upper layer of the skin and can help neutralize free radicals in skin
A great moisturising ingredient that softens the skin and reduces water loss from its upper layer. It also can be helpful in protecting skin from free radicals
An emollient that helps soften the skin
Moisturizing
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:
arginine pca, glycerin.
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: beeswax, butyrospermum parkii butter.
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
