Product Summary
"Kate Somerville - Kateceuticals Firming Serum" is effective for: Anti-aging and Moisturizing
Ingredient callouts
- Ceramides (ceramide ng 0.50% - 0.75%). Ceramides are an important part of our natural skin barrier. The Ceramides used in skincare are synthetic or come from plants. They help soften the skin and can help "fill the gaps" in the skin barrier, keeping the skin hydrated and resilient for longer.
- Peptides (palmitoyl tripeptide-5 0.40% - 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 theynare 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.
- Adenosine 0.50% - 0.75%. It is a compound that in involved in many biological processes inside the skin cells. According one high-quality clinical trial, topical Adenosine in low concentrations can somewhat help improve "deep wrinkles" - the wrinkles that appear with age in places where our faces are most dynamic (for example, on the forehead or in the corners of the eyes).
- Humectants (glycerin 3.10% - 3.80% and sodium hyaluronate 0.45% - 0.65%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Anti-aging
What does the product description say?
You’ll see visibly smoother texture and the appearance of elasticity and firmness in as little as two weeks.
Source: Sephora
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: palmitoyl tripeptide-5.
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.
Might help improve cell turnover and reduce inflammation in skin. One study shows that the ingredients might be able to help reduce dynamic wrinkles (for example, in the corners of the eyes or on the forehead)
A type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles
Is claimed to stimulate collagen and elastin production, as well as work as an anti-oxidant. There is however not enough evidence for its effectiveness
An emollient that helps soften the skin. Might be somewhat helpful in evening the skin tone.
Pure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself
Moisturizing
What does the product description say?
Hydrates and visibly plumps and smooths the skin’s appearance. . Vitamin E. Provides antioxidant benefits to nourish and help defend against free-radical damage.

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, 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: dimethicone, isocetyl stearate.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: ceramide ng, palmitoyl tripeptide-5
