What the product description says
“Recommended for body such as elbows and heels, dry scalp, and dry hair tips.”
Source: Yesstyle

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, butylene glycol.

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: simmondsia chinensis seed oil, squalane.

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.~26–39%
Ethylhexyl palmitateKey active· EmollientEffect: MediumAn emollient that helps soften the skin and create a nice product texture~5.6–8.4%
Simmondsia chinensis seed oilKey active· Emollient, OcclusiveEffect: 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.~5.4–8.2%
CyanocobalaminKey activeEffect: HighCan support skin barrier function and reduce inflammation in skin~0.2–0.8%
TricaprylinKey active· EmollientEffect: MediumAn emollient that helps soften the skin. Can increase penetration of other ingredients~0.2–0.8%

Zea mays oilKey activeEffect: HighA good moisturizing plant oil. Due to the high linoleic acid content, it helps soften the upper layer of the skin, reduce water loss and support skin barrier function~0.15–0.6%
GlutathioneKey activeEffect: HighA peptide that can help neutralize free radicals in skin and reduce melanin production resulting in skin lightening effect and reduction in hyperpigmentation. It can also help attract moisture to the upper layer of the skin~0.15–0.65%
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~0.15–0.5%
Pentylene glycol· EmollientEffect: LowUsed to preserve products, dissolve other ingredients and create a nice product texture~0.15–0.55%
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~0.2–0.75%

It does not penetrate the skin well, but has been shown to convert to pure vitamin C once in skin. It can be helpful in stimulating collagen production and lightening the skin tone, but the required concentration is likely to be very high~0.4–0.9%
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.~0.4–0.95%

Evens skin tone
Side benefit · Glutathione, Magnesium ascorbyl phosphate + 2 more
Works well

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

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.

GlutathioneKey activeEffect: HighA peptide that can help neutralize free radicals in skin and reduce melanin production resulting in skin lightening effect and reduction in hyperpigmentation. It can also help attract moisture to the upper layer of the skin~0.15–0.65%

Concentration of 4-6% is better for helping with acne and balancing the sebum production~0.35–0.8%
Retinyl palmitateUnder-dosedThree 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~0.35–0.8%
