From product name
WIMJ summary

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains palmitoyl hexapeptide-12.

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: acetyl hexapeptide-1, acetyl hexapeptide-8, acetyl octapeptide-3, acetyl tetrapeptide-11, acetyl tetrapeptide-2, acetyl tetrapeptide-9, dipeptide diaminobutyroyl benzylamide diacetate, hexapeptide-11, palmitoyl hexapeptide-19, palmitoyl oligopeptide, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, palmitoyl tripeptide-5, tetradecyl aminobutyroylvalylaminobutyric urea trifluoroacetate, trifluoroacetyl tripeptide-2, tripeptide-1, tripeptide-10 citrulline.

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 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: dextran, glycerin.

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, simmondsia chinensis seed oil.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl hexapeptide-1, acetyl hexapeptide-8, acetyl octapeptide-3, acetyl tetrapeptide-11, acetyl tetrapeptide-2, acetyl tetrapeptide-9, dipeptide diaminobutyroyl benzylamide diacetate, hexapeptide-11, palmitoyl hexapeptide-12, palmitoyl hexapeptide-19, palmitoyl oligopeptide, palmitoyl tetrapeptide-7, palmitoyl tripeptide-1, palmitoyl tripeptide-5, trifluoroacetyl tripeptide-2, tripeptide-1, tripeptide-10 citrulline

WIMJ summary

This product contains antioxidants (squalene) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.
