What does the product description say?WIMJ summary
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains heptapeptide-15 palmitate.
These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: aspartic acid, copper palmitoyl heptapeptide-14, folic acid, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, serine, sh-oligopeptide-1, sh-oligopeptide-2, sh-polypeptide-1, sh-polypeptide-11, sh-polypeptide-9, threonine.
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 does the product description say?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:
alanine, arginine.
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, glycine soja oil.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: copper palmitoyl heptapeptide-14, heptapeptide-15 palmitate, linoleic acid, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, sh-oligopeptide-1, sh-oligopeptide-2, sh-polypeptide-1, sh-polypeptide-11, sh-polypeptide-9
