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, lactobacillus ferment.

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, dimethiconol.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide

Exfoliation
Not advertised by the brand · Salicylic acid
Strong evidence

This product can help exfoliate the skin. In other words, it helps break down the bonds between dead cells on the surface of the skin and speed up the skin turnover. Skin often appears softer and brighter after exfoliation, but overdoing it can result in disrupted skin barrier. The following ingredient is doing the exfoliating job in this product: salicylic acid.

Anti-aging
Not advertised by the brand · Niacinamide, Zinc pca
Strong evidence

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

Product summary

Based on the ingredient list, "Kiehl's - Expertly Clear Moisturizer for Acne Prone Skin with Salicylic Acid" can work well for skin moisturization. To work well, any moisturizer needs to include a combination of water-binding and emollient ingredients. Kiehl's - Expertly Clear Moisturizer for Acne Prone Skin with Salicylic Acid ticks this box. Glycerin, lactobacillus ferment, zinc pca, butylene glycol and propylene glycol in this product (humectants) attract water molecules to the upper layer of the skin (the water comes from the outside air or from the deeper layers of the skin if the air is dry). Dimethicone, dimethiconol, cetearyl alcohol, glyceryl stearate and isohexadecane in this product help decrease the water evoporation from the skin, so that it stays hydrated for longer. These ingredients also soften the skin and take away the feeling of tightness and dryness.

Ingredient callouts

  • We particularly like that there is a good concentration of Niacinamide (2.70% - 4.10%) in this moisturizer. Niacinamide is a well-studied multi-tasking active. It is a great ingredient to have in a moisturizer. It is stable, and can work well in almost any hydrating formulation. There is solid evidence that Niacinamide can help support skin barrier, regulate oil production and reduce acne and clogged pores. It also helps to fight photodamage and help improve the skin tone, reducing pigmentation marks.
This product contains ingredients that could be beneficial, but their concentrations are too low in this formulation: dipotassium glycyrrhizate

Irritation risk

This formulation includes some common irritants, including ingredients that do not provide a benefit for the skin. We assess the overall irritancy of this moisturizer to be medium. For a detailed overview of all potential irritants: click here
