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

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~0.55–0.8%
Hydroxypinacolone retinoateHeroEffect: HighA derivative of the most potent form of vitamin A, retinoic acid. The ingredient can be sold under name Granactive Retinoid. Note that if a skincare brand discloses the concentration of Granactive Retinoid in a product, the concentration refers to a diluted form of Hydroxypinacolone Retinoate: 1% of Granactive Retinoid corresponds to 0.1% of Hydroxypinacolone Retinoate. Hydroxypinacolone Retinoate (HPR) is a unique derivative of retinoic acid because it can directly work in the skin and does not require additional conversion steps. According to studies done by the manufacturer on models of human skin (not real people), this derivative is more effective than other cosmetic versions of retinoids (such as retinol, retinaldehyde, and retinyl palmitate), and, at the same time, causes less irritation. It has been also demonstrated to be more stable than retinol which makes formulating with easier and increases the chances that a product with it will maintain its effectiveness after opening. The packaging should still ideally be air-tight. HPR is available over the counter in the EU, UK, Asia, Australia and New Zealand, but is only with a prescription in Canada.~0.01–0.05%
TaurineEffect: LowCould be helpful in reducing inflammation in skin, evening out the skin tone and neutralizing free radicals, but more research is needed to confirm its effectiveness~0.25–0.45%
Retinyl linoleateUnder-dosedAn ester of a retinoid and linoleic acid. Three steps removed from the bioactive form of retinoid, retinoic acid. Once converted to retinoic acid in skin, it can help reduce wrinkles, stimulate collagen production, even out skin tone and reduce blemishes. The concentrations used in cosmetic products are often not high enough to have a positive effect in skin.~0.5–0.75%
Lactic acidUnder-dosedAn exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid. At high concentrations (about 15%), lactic acid can help reduce lines and wrinkles. Recent studies show that lactic acid can support the "good" bacteria living on skin's surface (healthy skin microbiome)~0.2–0.4%

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

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
“Loaded with a replenishing host of ingredients starring squalane, hyaluronic acid, swertia flower extract, tomato and soybean extracts just to name a few, this fast-acting formula works to increase your skin's resilience and deliver a surge of hydration to the areas that need it most.”
Source: Cultbeauty

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: betaine, 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, squalane.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: urea

Product summary

"Murad - Retinol Youth Renewal Serum" is effective for: Evens skin tone, Anti-aging, Exfoliation, Moisturizing and Anti-blemish

Ingredient callouts

  • this product contains an effective form of Retinoids (vitamin A): retinol 0.70% - 1.00% and hydroxypinacolone retinoate 0.05% - 0.05%. Retinoids are potent multitasking actives. They work to improve and prevent early signs of aging, reduce hyperpigmentation (age spots and post-acne marks), and prevent inflamed blemishes and clogged pores. The downside of Retinoids is that they can be irritating. If you are not already using a Retinoid in your routine, it is best to start slowly and apply the Retinoid product only a few times per week. If your skin tolerates it well, you can gradually increase the frequency to daily.
  • Ceramides (ceramide np 0.55% - 0.85%). Ceramides are a type of lipids that our skin produces itself. They are a building block of the skin's barrier. Ceramides used in skincare are synthetic or extracted from plants. They work well for softening the skin surface and "patch holes" in the skin's barrier.
  • Humectants (sodium hyaluronate 0.50% - 0.70%, betaine 0.25% - 0.45%, urea 0.30% - 0.50%, trehalose 0.25% - 0.50%, inositol 0.25% - 0.50% and glycerin 0.30% - 0.55%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
