“Substiane Riche Replenishing Face Moisturizer for Dry Skin”
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, bis-peg-18 methyl ether dimethyl silane.
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
Anti-aging3 ingredients credited for this claimModerate support
“Acts against skin sagging for visibly firmer skin.”
This product contains acetyl dipeptide-1 cetyl ester, serine. These ingredients 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
"La Roche-Posay - Substiane Riche Replenishing Face Moisturizer for Dry Skin" is a well-rounded moisturizing product. To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. La Roche-Posay - Substiane Riche Replenishing Face Moisturizer for Dry Skin ticks this box. Glycerin, bis-peg-18 methyl ether dimethyl silane and propylene 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). Emollients in this formulation (prunus armeniaca kernel oil, beeswax, butyrospermum parkii butter, cera alba and dimethicone) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.
Ingredient callouts
- This moisturizer also contains Peptides (acetyl dipeptide-1 cetyl ester 0.20% - 0.35%). Peptides are a very big group of ingredients. They all consist of a different combination of aminoacids. Our skin produces Peptides naturally. Some of them work as natural antibiotics, promote wound-healing and production of collagen. The scientists are still studying how effective the topical application of Peptides is, but it is very likely that they are helpful. Peptides might be able to support skin barrier restoration and even have an anti-aging benefit. At the very least, they certainly help attract water to the skin and support the hydration in this way.
Irritation risk
