Evens skin tone3 ingredients credited for this claimStrong support
“It even carefully exfoliates to even out texture, minimising roughness while supporting a normal, fortified surface.”
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: niacinamide
The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually can help even out the skin tone: glycine soja protein.
Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.
Anti-aging5 ingredients credited for this claimStrong support
“Completely weightless while packing an anti-ageing punch, the Kiehl's moisturising gel is specially formulated with men’s thicker skin in mind.”
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains adenosine, niacinamide.
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.

“Age Defender Gel Moisturiser”
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, glycine soja protein.
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, peg-10 dimethicone.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide

Ingredient callouts
- We love that this moisturizer contains a good concentration of niacinamide 2.70% - 4.10%. Niacinamide is a perfect active in a moistruizer because it helps calm down inflamation in skin and support the skin barrier. More than that, it is helpful for most common skin concerns: it helps regulat oil production, help reduce acne and clogged pores, improve skin tone and prevent pigmentation marks. It also helps fight photodamage.
- Adenosine 0.10% - 0.45%. It is a chemical present inside our skin cells. A clinical trial confirmed that topical application of Adenosine in a low concentration can reduce dynamic wrinkles (these are the wrinkles that appear with age in a places where our mimic is the most active, for example, in the corners of the eyes or on the forehead).
