What the product description says
“This night cream is perfect for ageing skin and ideal for intensive overnight repair, visibly smoothing wrinkles and fine lines, and restoring firmness and elasticity as you rest.”
Source: Supderdrug

This product contains retinyl palmitate. This ingredient might be able to help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness, but there is not enough evidence that it actually works.

Retinyl palmitateKey activeEffect: 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~0.3–0.55%
TocopherolEffect: Low, below effective dosePure 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~0.3–0.5%
Zinc gluconateEffect: Low, below effective doseTypically used to stabilize the product formulations. It is a salt of a polyhydroxy acid (PHA) and in larger concentrations, can help shed the dead cells from the skin surface revealing smoother skin. It can help attract water to the upper layer of the skin. Might to be helpful against acne and clogged pores. Could be helpful in neutralizing free radicals, but solid research is missing. Due to the zinc content, might help calm down inflammation in skin~0.25–0.5%
Copper gluconateEffect: Low, below effective doseTypically used to stabilize the product formulations. It is a salt of polyhydroxy acid (PHA) and in larger concentrations, can help shed the dead cells from the skin surface revealing smoother skin. It can help attract water to the upper layer of the skin. Might to be helpful against acne and clogged pores. Could be helpful in neutralizing free radicals, but solid research is missing~0.15–0.25%

What the product description says
“Renew Your Skin While You Sleep With This Hydrating Night Cream!”
Source: Supderdrug

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, mannitol.

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, dimethiconol.

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~3.9–4.7%
DimethiconeKey active· Emollient, OcclusiveEffect: HighA silicone that helps to reduce water loss from the surface of the skin. Can temporarily "fill in" lines and wrinkles, absorb oil, and create a nice product finish~3.1–3.8%
Cetyl alcoholKey active· EmollientEffect: MediumA non-drying alcohol that works to soften the skin and stabilize product formulations helping oil and water mix together~2–2.4%
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.~1.3–1.5%
DimethiconolKey active· Emollient, OcclusiveEffect: HighA silicone that makes products more spreadable and keeps skin smooth. Helps to add gloss to skin and may visually fill in fine lines/wrinkles for short time~0.65–0.95%
Beta-sitosterolKey active· EmollientEffect: HighA phytosterol that can support skin's barrier function and help the skin stay hydrated~0.3–0.55%
CholesterolKey active· EmollientEffect: HighAn emollient that is naturally found in skin~0.3–0.6%
Glycine soja oilKey active· EmollientEffect: HighA good emollient that helps soften the skin and helps repair its barrier function. It can clog pores if used in high concentrations.~0.3–0.55%
MannitolKey active· HumectantEffect: HighHelps to attract water to the upper layer of the skin~0.3–0.5%
Magnesium aspartateKey activeEffect: MediumMight be helpful in restoring skin barrier function and calm down inflammation in skin~0.3–0.55%
SqualeneKey active· Emollient, OcclusiveEffect: HighAn oil that is naturally part of skin sebum that helps to soften its upper layer, reduce water loss and neutralize free radicals. It might be comedogenic. Avoid applying large concentrations (or pure oil) before sun exposure as oxidized squalene can clog pores and lead to skin irritation. Today squalene is mostly derived from vegetable oils or synthetized by yeast~0.2–0.4%
Glyceryl stearate· EmollientEffect: LowAn emollient that softens the skin and forms a protective layer on its surface. Helps water and oil mix together~1.7–2%
Isononyl isononanoate· Emollient, OcclusiveEffect: LowForms a protective film on the surface of the skin to prevent moisture loss. Gives a velvety feel to products while reducing tackiness~1.5–1.8%
