Judging from the ingredient list, "SEPHORA COLLECTION - Base ultra-lissante Beauty Amplifier" works well for improving skin hydration 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. Sodium hyaluronate 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). Palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, c12-15 alkyl benzoate and cyclopentasiloxane 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 (palmitoyl tripeptide-1 0.15% - 0.65% and palmitoyl tetrapeptide-7 0.15% - 0.60%). There are many different kind of peptides and they are naturally present in our skin. They all are a combination of amino-acids. Some of them work as natural anti-biotics, promote wound-healing and production of collagen. The science is still not settled on how effective peptides in skincare are, 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.

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:
sodium hyaluronate.
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:
palmitoyl tetrapeptide-7, palmitoyl tripeptide-1.
The following ingredients in this product are especially good for supporting the skin barrier and helping with
the hydration level: palmitoyl tetrapeptide-7, palmitoyl tripeptide-1
A type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles

Anti-aging
This product contains palmitoyl tetrapeptide-7, palmitoyl tripeptide-1.
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.
An exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)
