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 lactate.

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: butyrospermum parkii butter, rosa canina fruit oil.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: urea

UreaHero· HumectantEffect: HighNaturally present in skin (urea makes up about 7% of natural moisturizing factors in skin). Attracts water to the upper layer of the skin. Also has a positive effect on the skin barrier beyond the humectant action. Can enhance penetration of other ingredients. Is an exfoliating ingredient when used in high concentrations~0.25–0.45%
Butyrospermum parkii butterKey active· Emollient, OcclusiveEffect: HighA great moisturising ingredient that softens the skin and reduces water loss from its upper layer. It also can be helpful in protecting skin from free radicals~5.2–6.4%
Rosa canina fruit oilKey active· EmollientEffect: HighA great emollient. Contains vitamin E (tocopherol) which may give it some anti-oxidant properties. Can contain volatile compounds and can be irritating~4.5–5.5%
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~0.55–0.8%
TriheptanoinKey activeEffect: HighA synthetic triglyceride. Helps soften the upper layer of the skin~0.55–0.8%
SerineKey activeEffect: HighAn amino-acid that helps to attract water to the upper layer of the skin. In combination with other amino-acids, might help to reduce fine lines and wrinkles~0.25–0.45%
Sodium lactateKey active· HumectantEffect: HighHelps attract water to the upper layer of the skin. Is often used to adjust the pH level of the product~0.25–0.45%
LysolecithinEffect: LowLecithin derivative. It helps oil and water mix together and can enhance penetration of other ingredients. It helps soften the upper layer of the skin~2.3–2.8%
Pentylene glycol· EmollientEffect: LowUsed to preserve products, dissolve other ingredients and create a nice product texture~0.4–0.6%
Sorbitol· HumectantEffect: LowHelps attract water to the upper layer of the skin and improves the product texture~0.25–0.45%
Olus oil· EmollientEffect: LowAn oil from a mixture of different vegetables. Helps soften the upper layer of the skin~0.25–0.5%
Cucumis sativus fruit extractEffect: Low, below effective doseMight be somewhat helpful in reducing hyperpigmentation and neutralizing free radicals but its typical concentration in a product is too low for having an effect~1.1–1.4%
LecithinEffect: Low, below effective doseUsed mostly for creating emulsions - helping oil and water mix together. Helps soften the upper layer of the skin~0.3–0.55%
Ascorbyl tetraisopalmitateEffect: Low, below effective doseA vitamin C derivative. Studies show that is might be effective in reducing hyperpigmentation, but there are no studies confirming that it is effectively converted into the bioavailable form of Vitamin C in skin. It is not clear how this derivative compares in effectiveness to the topical application of bioavailable form of vitamin C (L-ascorbic acid)~0.2–0.35%
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~0.2–0.35%
Lactic acidUnder-dosedAn exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)~0.25–0.45%
AllantoinUnder-dosedHelps calm down inflammation in skin and can help reduce itching. Helps to repair the skin barrier and keep skin hydrated~0.15–0.3%

What the product description says
“Packed with brightening and moisturising actives, your skin will feel instantly hydrated and radiant as soon as you wake up.”
Source: Mio

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: mandelic acid

Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.

Mandelic acidKey activeEffect: HighHelps shed the upper layer of dead cells from the surface of the skin revealing smoother, brighter skin. It can help to reduce hyperpigmentation. It has anti-bacterial properties, and might help to reduce blemishes, as well as fine lines and wrinkles. It is considered to be gentler than glycolic acid~0.45–0.65%
Lactic acidUnder-dosedAn exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)~0.25–0.45%

What the product description says
“As you sleep, this AHA body lotion gets to work to resurface your skin cells and give you noticeably glowier skin.”
Source: Mio

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: mandelic acid.
