What the product description says
“Magic Star™ Hydrating Moisturizer”
From product name

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: alanine, betaine.

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, dimethicone.

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

Simmondsia chinensis seed oilKey activeEffect: HighSoftens the upper layer of skin and helps restore the healthy skin barrier. Has shown to help calm down inflammation in skin. It is a stable oil, meaning that it retains its properties even when exposed to air.~2–2.4%
Sodium hyaluronateKey activeEffect: HighOne of the best moisturizing ingredients. Attracts water into the upper layer of the skin~0.2–0.35%
AlanineKey activeEffect: HighAn amino-acid that helps to attract water to the upper layer of the skin and might help to lighten the skin, but solid evidence is lacking~0.15–0.25%
Corallina officinalis extractKey activeEffect: HighRed algae extract that helps attract water to the upper layer of the skin and might contain antioxidants~0.2–0.4%
DimethiconeKey activeEffect: 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~1.2–1.5%
GlycerinKey activeEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~4.9–5.9%
SqualaneKey activeEffect: 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.~2.4–2.9%
NiacinamideHeroEffect: HighIs proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production~3–3.7%
PhytosterolsKey activeEffect: HighLipids that work as an emollient and can be helpful in repairing skin barrier function~0.45–0.7%
BetaineKey activeEffect: HighHelps attract water to the upper layer of the skin and improves the product texture~0.2–0.4%

Behenyl alcoholEffect: LowNon-drying alcohol that helps water and oil mix together. Also serves as an emollient~1–1.2%
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~0.15–0.25%
Anti-aging
Not advertised by the brand · Niacinamide, Serine + 1 more
Strong evidence

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

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: serine.

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.

NiacinamideKey activeEffect: HighIs proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production~3–3.7%
SerineKey activeEffect: MediumAn 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~0.2–0.35%
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~0.15–0.25%
Evens skin tone
Not advertised by the brand · Niacinamide, Alanine
Strong evidence

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

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually can help even out the skin tone: alanine.

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.

NiacinamideKey activeEffect: HighIs proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production~3–3.7%
