Hemp-derived cannabidiol, included in our formulas for skin that feels reactive. We make no claim about what it does to skin, because no skin study stands behind one.

Ease in the formula

Cannabidiol (CBD) sits in our formulas for one job: keeping reactive skin comfortable. We file it under Calming in this glossary for the job we use it for, and the evidence section below says why no study is cited.

Ease in the signal

We make no efficacy claim for Cannabidiol (CBD). Its role is functional, and our own note against it reads: (comfort claim; Tier 4 mechanism only, no skin RCT, hedged). A functional ingredient dressed up as an active is still a functional ingredient, so we leave it described as what it is.

Ease in the evidence

No study is cited here because no efficacy claim is made. That is a deliberate entry in this glossary rather than a gap in it.

Ease and its limits

Cannabidiol (CBD) is included for how it makes a formula behave, not for what it does to skin. Anyone telling you otherwise about an ingredient of this type is selling something.
