Kiehl's Rare Earth Deep Pore Purifying Concentrated Cleansing Bar

This product works by removing dirt and oil from the surface of the skin. It uses a combination of mild cleansing agents (arachidic acid, coconut acid, myristic acid, palmitic acid, sodium cocoyl glycinate, sodium cocoyl isethionate, stearic acid) and should be able to cleanse the skin gently. Still keep in mind that any cleansing can disrupt the skin barrier, and most people do not need to cleanse their skin more than once per day.

Effective ingredients missing or their concentration is too low.

This product does not contain effective exfoliating ingredients. It might be able to deliver physical exfoliation, that is scrub off some of the dead cells on the surface of the skin. We do not recommend physical exfoliation, because it is not uniform (some bits of skin can get exfoliated too much while others not at all). It can also traumatize the skin and aggrevate acne and other skin conditions.
