Anti-aging
What does the product description say?
Powered by 10% THD Ascorbate, an ingredient that boasts 50x the ability of Vitamin C, the formula works to unify the skin tone and texture by brightening brown spots and smoothing out fine lines and wrinkles.
Source: Beauty Expert
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains tetrahexyldecyl ascorbate.
These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: ferulic acid.
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.
Being 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.
A potent anti-oxidant that has been shown to be effective in neutralizing free radicals in skin. There seem to have a synergetic effect of ferulic acid, vitamin E and C, meaning that when the ingredients are used together, they enhance each other's ability protect the skin against free radicals. Ferulic acid also helps to stabilize other ingredients - including vitamins C and E. It can help to even out the skin tone. Ferulic acid is approved for use as a sunscreen ingredient in Japan in concentrations up to 10%
Might be helpful in restoring skin barrier function and, when combined with zinc carbonate and malonic acid, reducing fine lines and wrinkles by stimulating elastin production. Also helps stabilize the product formulation
Traditionally used to treat sunburns, dermatitis and inflammation, but evidence for its effectiveness is lacking. The extract can contain humectants that help attract water into the skin
Anti-oxidation
This product contains antioxidants (ferulic acid, tetrahexyldecyl ascorbate) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: tetrahexyldecyl ascorbate
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: ferulic 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.

Moisturizing
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: dimethicone, cetearyl alcohol.
One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant
A 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
A non-drying alcohol. Works as an emollient. Helps water and oil mix together and creates a nice product texture
Used 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
An emollient that softens the skin and forms a protective layer on its surface. Helps water and oil mix together
Helps soften the upper layer of the skin and create a thicker product consistency
Helps water and oil mix together while softening the upper layer of the skin. Can be an allergen (beeswax)
Helps calm down inflammation in skin and can help reduce itching. Helps to repair the skin barrier and keep skin hydrated
Traditionally used to treat sunburns, dermatitis and inflammation, but evidence for its effectiveness is lacking. The extract can contain humectants that help attract water into the skin
