What it is

An extract made from the leaves and roots of the hinoki cypress tree (Chamaecyparis obtusa), a plant traditionally used in Japanese baths and aromatherapy for its calming scent and potential skin benefits.

How it works

It contains compounds like hinokitiol and other antioxidants that help neutralize free radicals (unstable molecules that can damage skin cells). It may also have mild anti-inflammatory effects, helping to calm redness and irritation.

Pros

Cons and cautions

Limited research

Most evidence comes from lab studies or traditional use; there are few high-quality human trials confirming its benefits in skincare.

Natural scent may be an issue

The extract has a distinct woody aroma that some people may find overpowering or unpleasant, especially if they prefer unscented products.
