Key actives
Anti-oxidation
This product contains antioxidants (camellia sinensis leaf extract) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.
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
A product of yeast fermentation. Can contain humectants that help attract water to the upper layer of the skin and might help neutralize free oxidants
A 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)
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
A more stable but less bio-available form of vitamin E compared to Tocopherol. Might help moisturize and protect the skin from free radicals, but mostly used in low concentrations to stabilize other ingredients.
Evens skin tone
The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually works: stearyl glycyrrhetinate.
A fatty acid derived from licorice. Works as an emollient and can help calm down inflammation

Moisturizing
What does the product description say?
TATCHA The Dewy Serum is a hydrating facial serum designed to leave skin looking plump, smooth and comfortably moisturised.

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, hydrolyzed collagen.
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, squalane.
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 typically plant-derived compound that is supposed mimic human collagen. Cannot penetrate the skin barrier so is not particularly useful in skincare products beyond attracting water to the upper layer of the skin
Helps soften the upper layer of the skin
One of the best moisturizing ingredients. Attracts water into the upper layer of the skin
An 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.

Non-drying alcohol that helps water and oil mix together. Also serves as an emollient

Anti-aging
What does the product description say?
A blend of hydrolysed elastin and collagen amino acids helps to promote the look of improved elasticity and a smoother surface over time, so fine lines appear less noticeable and texture feels refined.

This product does not contain ingredients that are able to reduce fine lines and wrinkles or help with skin elasticity, but it can improve the look of the skin temporarily through moisturization. Well-moisturized skin might also be able to repair the sun damage better.This ingredient - camellia sinensis leaf extract - could be helpful for preventing or repairing signs of aging in theory, but there is no evidence that it actually works.
This ingredient camellia sinensis leaf extract might be able to help neutralize free radicals in skin and help it fight off some of the sun damage.
