What the product description says
“You'll see visible improvements in fine lines and wrinkles, smoothness, brightness, firming, dark spots, and pores.”
Source: Ulta

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

In addition, this product contains niacinamide. This ingredient (ingredients) might help reduce hyperpigmentation, but the effect, if any, is likely to be small.

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.

RetinolHeroEffect: HighTwo steps removed from the active form of vitamin A - retinoic acid. Once converted to the retinoic acid in the skin, retinol is proven to be effective against all signs of aging. It improves skin cell turnover, helps fight blemishes and clogged pores, can regulate excess oil production and even skin tone. It can, however, be quite irritating~1–1.45%
NiacinamideKey activeEffect: HighIs proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production~4–5.9%

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

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: palmitoyl pentapeptide-4.

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.

What the product description says
“Olay's proprietary blend of vitamin B3 + retinol complex hydrates skin for 24 hours for a bounty of benefits.”
Source: Ulta

This product can help improve hydration of the skin with the two types of ingredients.

The first type is called “humectants”:
these ingredients help attract water. 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. The following ingredients in this product do the job: glycerin.

This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: dimethicone, dimethiconol.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide, palmitoyl pentapeptide-4
