Anti-aging
What does the product description say?
Skin Type Normal, Dry, Combination, and Oily Skincare Concerns Fine Lines, Wrinkles, Loss of Firmness and Elasticity Highlighted Ingredients , Tetrahexyldecyl Ascorbate (10% THD-Ascorbate) Visibly improves skin brightness and pigmentation with continued use.
Source: Sephora CA
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: acetyl zingerone.
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.
An active compound sourced from ginger root. It can help neutralize free radicals in skin. It might be able to help reduce fine lines and wrinkles and improve the skin tone. In small concentrations, used as a chelating agent and helps preserve stability of product formulations.
Can contain potent anti-oxidant compounds (abbreviated ECG, GCG, EGC, and EGCG) that might help protect the skin from free radicals. Can help calm down inflammation and has some anti-bacterial properties. Unfortunately, these antioxidants are unstable and lose their effectiveness very quickly in products. The concentration of the antioxidant compounds in the extract also tends to be low to be effective in topical formulation
Pure 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
Seaweed extract that helps the skin to attract water and make it more smooth for touch. Also shows promise of anti-aging properties, but good research is lacking at the moment

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: tetrahexyldecyl ascorbate
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
What does the product description say?
What it is A hydrating, multitasking formula that is packed with antioxidants.
Source: Sephora CA
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, bis-peg-18 methyl ether dimethyl silane.
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.
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 great emollient due to its high linoleic acid content. One of the most effective plant oils in helping skin hydration and repairing skin barrier function
A micro-algae extract that might help attract water to the upper layer of the skin, support its barrier function, amd might help neutralize free radicals, but evidence of effectiveness in skin is lacking
One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant
