Caudalie Instant Firming Serum

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains adenosine.

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: acetyl dipeptide-1 cetyl ester.

Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.

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, hyaluronic acid.

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: squalane, hexyldecanol.

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

This product contains antioxidants (palmitoyl grapevine shoot extract) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.
