Judging from the ingredient list, "Paula's choice - Pro-Collagen Peptide Plumping Moisturizer" works well for improving skin hydration The formulation is based on a combination of good humectants and emollients. Both are needed to increase the skin hydration level. Glycerin and butylene 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). Dimethicone, squalane and pentylene 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
This moisturizer also contains Peptides (oligopeptide-1 0.15% - 0.60%). 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.
This product contains ingredients that could be beneficial, but their concentrations are too low in this formulation: lecithin

reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness, but there is not enough
evidence that it actually works.
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:
dimethicone, squalane.
The following ingredients in this product are especially good for supporting the skin barrier and helping with
the hydration level: oligopeptide-1
