What the product description says
“Over time, collagen production is boosted; dark spots are cleared, and skin glows with a brilliant smoothness.”
Source: Beautylish

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains tetrahexyldecyl ascorbate.

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.

Tetrahexyldecyl ascorbateKey activeEffect: HighBeing 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.~4.9–7.4%
3-o-ethyl ascorbic acidEffect: LowA 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~9–13.5%

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: glutathione, 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: 3-o-ethyl ascorbic 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.
