What the product description says
“Introducing the r-Retinoate Day and Night Eye Serum (15ml), a gentle yet effective formula that fades the look of dark circles, fine lines and wrinkles.”
Source: Cultbeauty

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

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.

Retinyl retinoateHeroEffect: HighA "hybrid" of retinol and retinoic acid. It is more stable than retinol and is likely to be more effective based on the early research data available. Is as irritating as retinol~0.35–0.75%
Tetrahexyldecyl ascorbateUnder-dosedBeing a lipid soluble form of vitamin C, it is more stable than ascorbic acid, but still degrades quickly and needs to be stabilized in a formulation with another ingredient. It is claimed to penetrate skin better than pure vitamin C and have the the similar benefits, but solid studies of its effectiveness are lacking. Is likely to require a higher concentration in a product than pure vitamin C to be effective. It might be able to help reduce pore clogging.~0.15–0.55%

What the product description says
“This potent powerhouse also calls on moisture-locking glycerin and hydrating hyaluronic acid to ensure your complexion is nourished and supple.”
Source: Cultbeauty

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, hydrolyzed glycosaminoglycans.

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: caprylic/capric triglyceride, squalane.

Caprylic/capric triglycerideKey active· Emollient, OcclusiveEffect: HighA good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin~4.9–7.4%
IsododecaneKey active· Emollient, OcclusiveEffect: MediumAn emollient that helps soften the skin and can decrease moisture loss. Helps create a nice product texture~3.7–5.6%
Cetearyl alcoholKey active· EmollientEffect: MediumA non-drying alcohol. Works as an emollient. Helps water and oil mix together and creates a nice product texture~2.2–3.3%
GlycerinKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~1.8–2.7%
SqualaneKey active· Emollient, OcclusiveEffect: HighAn oil naturally present in skin. Works as an emollient to soften the skin and form a protective layer on its surface without a greasy feeling.~0.5–1.15%
Hydrolyzed glycosaminoglycansKey active· HumectantEffect: HighLong sugars that help attract water to the upper layer of the skin~0.15–0.65%
Sodium hyaluronateKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.15–0.55%
Canola oilKey active· EmollientEffect: MediumA plant oil that can help soften the upper layer of the skin~0.15–0.55%
Glucosyl hesperidinKey active· HumectantEffect: MediumMight be able to neutralize free radicals in skin. Also works as a humectant~0.15–0.5%
Butylene glycol· HumectantEffect: LowUsed to create a nice product texture and help delivery of other ingredients. Might be somewhat helpful in attracting water to the upper layer of the skin~0.1–0.35%
Scutellaria baicalensis root extract· HumectantEffect: LowA plant extract that might contain a compound baicalin that could be helpful in neutralizing free radicals and reducing inflammation in skin. The baicalin concentration in skincare products is often too low for an effective action. Can be used for its fragrant properties~0.1–0.4%
Evens skin tone
Retinyl retinoate, Tetrahexyldecyl ascorbate
May help
What the product description says
“Formulated with Medik8-exclusive encapsulated retinyl retinoate is proven to be gentle yet 8x more powerful than standard retinol* in delivering visible results, visibly softening fine lines and wrinkles, reducing pigmentation, and refining overall skin texture.”
Source: Face the future

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually works: retinyl retinoate.

Retinyl retinoateHeroEffect: MediumA "hybrid" of retinol and retinoic acid. It is more stable than retinol and is likely to be more effective based on the early research data available. Is as irritating as retinol~0.35–0.75%
Tetrahexyldecyl ascorbateUnder-dosedBeing a lipid soluble form of vitamin C, it is more stable than ascorbic acid, but still degrades quickly and needs to be stabilized in a formulation with another ingredient.

Exfoliation
Side benefit · Retinyl retinoate, Polylactic acid
Works well

This product can help exfoliate the skin. In other words, it helps break down the bonds between dead cells on the surface of the skin and speed up the skin turnover. Skin often appears softer and brighter after exfoliation, but overdoing it can result in disrupted skin barrier. The following ingredient is doing the exfoliating job in this product: retinyl retinoate.

Retinyl retinoateKey activeEffect: HighA "hybrid" of retinol and retinoic acid. It is more stable than retinol and is likely to be more effective based on the early research data available. Is as irritating as retinol~0.35–0.75%
Polylactic acidEffect: LowUsed as an abrasive ingredient for physical (mechanical) exfoliation~1.2–1.8%
