What does the product description say?
"A powerhouse anti-ageing serum, the Powerful-Strength Line-Reducing Concentrate contains a 12."
WIMJ summary

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

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: adenosine, palmitoyl oligopeptide, palmitoyl tetrapeptide-7.

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.

WIMJ summary

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

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually can help even out the skin tone: chrysin.

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.

What does the product description say?
"An added infusion of low molecular weight hyaluronic acid works alongside to offer its highly effective hydrating and skin-plumping power, for a complexion that looks completely energised."
WIMJ summary

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, propylene glycol.

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: palmitoyl tetrapeptide-7, cyclopentasiloxane.

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