Ingredient review
Taiwan Cypress Wood Oil
INCI: Chamaecyparis formosensis wood oil
A fragrant wood oil with limited research on skincare benefits; best appreciated for its scent rather than proven skin effects.
In plain English
Taiwan Cypress Wood Oil is an essential oil pressed from the wood of a tree native to Taiwan. In skincare, it's mainly used to give products a warm, woody scent. There's very little scientific research on how it affects skin, so its benefits are mostly based on tradition and aroma rather than hard evidence. Like many essential oils, it can cause irritation in some people, especially if used at high concentrations.
