Ingredient callouts

- Humectants (glycerin 4.30% - 6.40% and biosaccharide gum-1 0.10% - 0.45%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.

Anti-aging
What does the product description say?
Kiehl's Age Defender Power Serum Strengthening, visibly lifting, anti-wrinkle treatment for men.
Source: Feelunique
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains adenosine.
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.
Might help improve cell turnover and reduce inflammation in skin. One study shows that the ingredients might be able to help reduce dynamic wrinkles (for example, in the corners of the eyes or on the forehead)
Pure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself
Moisturizing
What does the product description say?
Directions Use day and evening alone or with your moisturiser.
Source: Feelunique
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:
biosaccharide gum-1, 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, glycine soja oil.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: hydroxypalmitoyl sphinganine
Helps attract water to the upper layer of the skin and is claimed to provide a longer-lasting hydration because of its ability to create a water-binding film on the surface of the skin
A sugar-derived compound that helps to attract water to the upper layer of the skin and might be able to stimulate synthesis of skin's own moisturizing factors, but solid research is lacking. It could be irritating
A type of lipid similar to ceramides naturally present in skin. Helps to soften the upper layer of the skin and supports the skin barrier function to keep it hydrated. Can help to prevent inflammation in skin
A silicone that helps to reduce water loss from the surface of the skin. Can temporarily "fill in" lines and wrinkles, absorb oil, and create a nice product finish
One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant
A good emollient that helps soften the skin and helps repair its barrier function. It can clog pores if used in high concentrations.
Might help improve cell turnover and reduce inflammation in skin. One study shows that the ingredients might be able to help reduce dynamic wrinkles (for example, in the corners of the eyes or on the forehead)
Helps attract water to the upper layer of the skin. Might have some anti-oxidant properties
Helps attract water to the upper layer of the skin. Might have some anti-aging, anti-oxidant, and skin lightening properties, but solid evidence is missing

Forms a protective film on the surface of the skin to prevent moisture loss. Gives a velvety feel to products while reducing tackiness
Used to preserve products, dissolve other ingredients and create a nice product texture

Pure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself
