What the product description says
“This formula glides effortlessly onto skin to help visibly soften early expression lines* and revive natural vitality for a fresh, supple, and smooth feel***.”
Source: No7 US

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

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~2–2.5%
Ascorbyl glucosideUnder-dosedEffect: MediumA vitamin C derivative that is more stable but less potent than pure form of vitamin C. Has a potential to boost collagen production, nutralise free radicals and 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~0.25–0.5%

What the product description says
“Prime Forever™ Weightless Moisturizer”
Source: No7 US

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, sodium hyaluronate.

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, caprylyl glycol.

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