What the product description says
“Together, this trio works to visibly smooth fine lines, improve skin texture and support a firmer-looking complexion with continued use.”
Source: Skin Cupid

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

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.

RetinalHeroEffect: HighOne step removed from the biologically active in skin form of vitamin A. Once converted to the retinoic acid in the skin, retinal 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. Concentrations of 0.05% and 0.1% are shown to be effective. It can, however, be irritating~0.2–0.7%

What the product description says
“Niacinamide, Ceramide NP and Centella Asiatica Extract provides gentle soothing support, supporting the skin barrier and helping the skin stay comfortable as it adjusts to the retinoid actives.”
Source: Skin Cupid

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: arginine, fructooligosaccharides.

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: arginine, caprylic/capric triglyceride.

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