What the product description says

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, glycine.

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: cera microcristallina, dimethicone.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl hexapeptide-8, ceramide ng, dipeptide diaminobutyroyl benzylamide diacetate, palmitoyl hexapeptide-12, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, urea

What the product description says

“An incredibly powerful eye brightener, this Line Release Under Eye Repair Cream utilises an advanced Peptide Blend to smooth the look of wrinkles and reduce the appearance of puffiness.”

Source: Cultbeauty

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains palmitoyl hexapeptide-12.

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: acetyl hexapeptide-8, dipeptide diaminobutyroyl benzylamide diacetate, lysine, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1.

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.

Palmitoyl hexapeptide-12Key activeEffect: HighA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~0.25–0.5%

It might be somewhat helpful for evening out the skin tone. It might be able to support elastin production but solid research is lacking~0.3–0.55%

Retinyl palmitateUnder-dosedEffect: MediumThree steps removed from the active form of vitamin A - retinoic acid. To have an effect in the skin, it first needs to be converted twice to become the retinoic acid. This means it is less potent than retinol, but could also be less irritating. Once converted to the retinoic acid in the skin, it helps against all signs of aging, improves skin cell turnover and helps fight blemishes and clogged pores. However, in many cosmetic formulations, it is used in a concentration that is too low to have the full effect~0.25–0.4%

Ascorbyl palmitateEffect: Low, below effective doseBeing a lipid soluble form of vitamin C, it is more stable and can penetrate the skin better than L-Ascorbic acid. It is effective in protecting the skin from free radicals, as well as evening the skin tone, but is less effective in stimulating collagen production compared to L-Ascorbic acid.~0.25–0.45%

Product summary

Judging from the ingredient list, "Kate Somerville - Line Release Under Eye Repair Cream" 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. Acetyl hexapeptide-8, urea, glycerin, glycine and sodium pca 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). Ceramide ng, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, glycosphingolipids and cera microcristallina 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 includes a form of retinoids (vitamin A) - retinyl palmitate 0.25% - 0.40%, but this type of vitamin A is not very effective. It could in theory help with fine lines and wrinkles, but the effect is most likely minimal.
As a plus, this moisturizer also contains ceramides (ceramide ng 0.30% - 0.55%). Ceramides are a type of lipids that our skin produces itself. They are a building block of the skin's barrier. Ceramides used in skincare are synthetic or extracted from plants. They work well for softening the skin surface and "patch holes" in the skin's barrier.
This moistruizer also contains peptides (acetyl hexapeptide-8 0.45% - 0.65%, palmitoyl tripeptide-1 0.30% - 0.55%, palmitoyl tetrapeptide-7 0.30% - 0.55%, palmitoyl hexapeptide-12 0.25% - 0.50% and dipeptide diaminobutyroyl benzylamide diacetate 0.25% - 0.45%). Peptides is a very big group of ingredients. They all consist of a different combination of amino-acids. Our skin produces peptides naturally. Some of them work as natural anti-biotics, 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 peptides in skincare are helpful. They 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.
