What the product description says
“Enriched with Babchi Seeds, phyto-extracts, Marine Bamboo and an anti-wrinkle peptide (Drift Kelp extract), combined with a stable form of Vitamin C, the Youth Oil brightens and renews skin from the inside out, protecting its natural luminosity and defending it from further damage by external stressors.”

This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: bakuchiol

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.

BakuchiolKey activeEffect: HighA plant extract that is, though different in chemical structure, acts similar to retinoids. First studies show that it can help reduce fine lines and wrinkles, improve skin tone, reduce clogged pores and blemishes, and reduce inflammation. There is no conclusive evidence that bakuchiol is as effective as retinol however. The study that directly compared retinol with bakuchiol used bakuchiol applied twice daily compared to once per day for the retinol. According to this study, bakuchiol is less irritating than retinol. Bakuchiol is extracted from seeds of Babchi plant. Other parts of the plant contain coumarins that could cause allergic and irritant reactions. These compounds should be removed in the extraction process when bakuchiol is produced, but it is a good idea to be cautious and stay away from products that include the Babchi plant extracts other than purified bakuchiol to avoid irritation~0.5–1.1%
3-o-ethyl ascorbic acidUnder-dosedA 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~0.1–0.35%

What the product description says
“Preserve skin’s youthful firmness and glow with the  Sepai Sublime Youth Oil ; a detoxifying, facial oil that targets loss of elasticity and decline of collagen synthesis to stop ageing in its tracks.”
Source: Lookfantastic

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

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.

Side benefit · Caprylic/capric triglyceride, Olea europaea fruit oil + 3 more
Works

This product can help soften the skin and reduce its moisture loss with emollients and occlusives: caprylic/capric triglyceride, salvia hispanica seed oil.
