What the product description says
“• Targets discoloration at the source to reduce the look of discoloration & dark spots over time”
Source: Renee Rouleau

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.

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.~4.6–6.9%

What the product description says
“This luxurious, lightweight oil serum uses squalane and jojoba to deliver instant radiance, deep nourishment, and long-lasting softness.”
Source: Renee Rouleau

This product can help soften the skin and reduce its moisture loss with emollients and occlusives: simmondsia chinensis seed oil, squalane.

Keep in mind that this product does not contain effective ingredients to attract water to the upper layer of the skin. This is why an additional product with humectants like glycerin or hyaluronic acid can be helpful (apply it before this product for the best results).

SqualaneKey active· Emollient, OcclusiveEffect: HighAn 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.~25–38%
Simmondsia chinensis seed oilKey active· Emollient, OcclusiveEffect: HighSoftens the upper layer of skin and helps restore the healthy skin barrier. Has shown to help calm down inflammation in skin. It is a stable oil, meaning that it retains its properties even when exposed to air.~6.5–9.7%
Silybum marianum seed oilEffect: LowA plant oil that contains essential oils that can be irritating. Can help soften the upper layer of the skin. Might have some anti-oxidant activity but evidence is lacking~3.5–5.3%
TocopherolEffect: Low, below effective dosePure 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~0.8–1.2%
Anti-oxidation
Side benefit · Tetrahexyldecyl ascorbate, Silybum marianum seed oil + 2 more
Works well

Anti-aging
Side benefit · Tetrahexyldecyl ascorbate, Tocopherol
Works well

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.
