This product contains acetyl hexapeptide-8, palmitoyl oligopeptide, palmitoyl tetrapeptide-7, 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.

What does the product description say?WIMJ summary for moisturizing
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:
algae extract, allantoin.
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: beeswax, caprylic/capric triglyceride.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: acetyl hexapeptide-8, ceramide 3, linoleic acid, palmitoyl oligopeptide, palmitoyl tetrapeptide-7, palmitoyl tripeptide-5, panthenol

WIMJ summary for anti-oxidation
This product contains antioxidants (superoxide dismutase) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).
The following ingredients - camellia sinensis leaf extract, tartaric acid also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.
