What does the product description say?WIMJ summary
This product does not contain ingredients that are able to reduce fine lines and wrinkles or help with skin elasticity, but it can improve the look of the skin temporarily through moisturization. Well-moisturized skin might also be able to repair the sun damage better.These ingredients - hyaluronic acid, sodium ascorbyl phosphate - could be helpful for preventing or repairing signs of aging in theory, but there is no evidence that it actually works.
This ingredient sodium ascorbyl phosphate might be able to help neutralize free radicals in skin and help it fight off some of the sun damage.

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:
glycerin, hyaluronic acid.
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: caprylic/capric triglyceride, isopropyl myristate.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: linoleic acid
