What the product description says
“Dryness, Uneven Texture, and Loss of Firmness and Elasticity Formulation.”
Source: Sephora CA

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, lactic acid.

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: butyrospermum parkii butter, dimethicone.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: ceramide np, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, palmitoyl tripeptide-5

Palmitoyl tripeptide-1Hero· EmollientEffect: HighA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~0.45–0.65%
Palmitoyl tetrapeptide-7Hero· EmollientEffect: HighA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~0.35–0.65%
Ceramide npHero· EmollientEffect: HighA type of lipid similar to ceramides naturally present in skin. Helps to soften the upper layer of the skin and supports the skin barrier function to keep it hydrated. Can help to prevent inflammation in skin~0.3–0.55%
Palmitoyl tripeptide-5HeroEffect: HighA type of peptide. Peptides are excellent moisturizers and might be able support collagen production reducing fine lines and wrinkles~0.3–0.5%
C12-15 alkyl benzoateKey active· EmollientEffect: MediumEnhances the product texture and makes it more spreadable. Helps reduce water loss from the outer layer of skin. Extands the shelf life by preventing bacteria growth~5.2–6.4%
Butyrospermum parkii butterKey active· Emollient, OcclusiveEffect: HighA great moisturising ingredient that softens the skin and reduces water loss from its upper layer. It also can be helpful in protecting skin from free radicals~4.7–5.7%
Theobroma cacao seed butterKey active· EmollientEffect: HighHelps soften the upper layer of the skin and can be helpful in restoring the skin barrier function. Might have some anti-oxidant effect~3.4–4.2%
Lactic acidKey active· HumectantEffect: HighAn 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)~2.6–3.1%
GlycerinKey active· HumectantEffect: HighOne of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant~1.5–1.9%
DimethiconeKey active· Emollient, OcclusiveEffect: HighA silicone that helps to reduce water loss from the surface of the skin. Can temporarily "fill in" lines and wrinkles, absorb oil, and create a nice product finish~1–1.2%

Evens skin tone
Lactic acid
Works well
What the product description says
“It also increases the look of skin thickness with RegestrilTM‡ to fight future stretch marks while diminishing the look of uneven tone and texture with lactic acid complex.”
Source: Sephora CA

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

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.

Lactic acidKey activeEffect: HighAn exfoliating and moisturizing alpha-hydroxy acid (AHA). Typically causes less irritation than other AHAs, for example, glycolic acid.

This product contains lactic acid, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, palmitoyl tripeptide-5. These ingredients might be able to help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness, but there is not enough evidence that it actually works.

Exfoliation
Not advertised by the brand · Lactic acid
Works well

This product can help exfoliate the skin. In other words, it helps break down the bonds between dead cells on the surface of the skin and speed up the skin turnover. Skin often appears softer and brighter after exfoliation, but overdoing it can result in disrupted skin barrier. The following ingredient is doing the exfoliating job in this product: lactic acid.
