Key actives
Anti-oxidation
This product contains antioxidants (ferulic acid) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).
The following ingredients - 3-o-ethyl ascorbic acid, epigallocatechin gallate also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.
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%
A vitamin C derivative that is more stable but less potent than pure form of vitamin C. Can help neutralize free radicals and help reduce hyperpigmentation, but the required concentration is likely to be much higher than for the pure form of vitamin C, limiting the ingredient's effectiveness in products
A polyphenol found in tea. This particular compound abbreviated EGCG is the most powerful antioxidant among those extracted from tea (usually green tea). Unfortunately, EGCG is unstable, requires a low pH (below 4) to prevent quick degradation, and does not penetrate the skin very well. This is why the full anti-oxidant effect of EGCG is typically not realized when it is added to topical skincare
A plant extract that might have some anti-oxidant effect in skin, but evidence is lacking
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

Moisturizing
This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": glycerin, sodium hyaluronate.
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. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).
One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant
