Anti-aging
What does the product description say?
T-ZONE Vitamin C & Kumquat Glo Serum is specially formulated with Kumquat, Aloe and photostable Vitamin-C. Each bottle is packed with 3% Vitamin C for brightening skin tone while combating skin blemish and hyperpigmentation.
Source: Supderdrug
This product contains ascorbyl glucoside. This ingredient might be able to help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness, but there is not enough evidence that it actually works.
A vitamin C derivative that is more stable but less potent than pure form of vitamin C. Has a potential to boost collagen production, nutralise free radicals and 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 compound that combines zinc with a hydrating ingredient PCA. Might to be helpful against acne and clogged pores. Can help calm down inflammation in skin. Could be helpful in reducing the formation of free radicals in skin. Might help to reduce fine lines in wrinkles, but solid evidence is missing
A stable derivative of vitamin C. It is oil-soluble which means it is more likely to penetrate the skin compared to the pure form of vitamin C (which is water-soluble), but it is less bio-available and is way less effective in stimulating collagen and reducing wrinkles compared to the pure form of vitamin C (L-ascorbic acid) and its other derivatives (for example, magnesium ascorbyl phosphate). At the same time, this vitamin C derivative has been shown in studies to be effective in reducing acne, blemishes and clogged pores. It is less irritating then the pure form of vitamin C
Anti-oxidation
This product contains antioxidants (ascorbyl glucoside) 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.

A plant extract that might help neutralize free radicals in skin, but research on its efficacy in skin is lacking

Moisturizing
This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": glycerin, zinc pca.
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).
Red algae extract that helps attract water to the upper layer of the skin and create a nicer product consistency
One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant

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
