Ingredient review
Acetylated Cypress Wood Extract
INCI: CUPRESSUS FUNEBRIS WOOD EXTRACT ACETYLATED
A gentle, modified wood extract that may help protect skin from environmental stress, but research on its specific benefits is still limited.
In plain English
This ingredient is a version of an extract from the wood of a type of cypress tree (Cupressus funebris) that has been chemically modified through acetylation. In simple terms, acetylation is a process that can make the extract more stable and easier for skincare products to work with. It's thought to have antioxidant properties, meaning it may help protect your skin from damage caused by things like pollution and UV rays. However, because it's a less common ingredient, there isn't a lot of independent research on how well it works compared to more well-known antioxidants like vitamin C or E.

What it is
A semi-synthetic ingredient derived from the wood of the mourning cypress tree, modified via acetylation to improve stability and efficacy in cosmetic formulations.
How it works
The acetylated extract is believed to function as an antioxidant, helping to neutralize free radicals that can cause premature skin aging. It may also have soothing properties, potentially calming minor skin irritation. The acetylation process may enhance its ability to penetrate the skin or remain stable in a formula.
Pros
Gentle on skin
The acetylation process may reduce potential irritation from the raw plant extract, making it suitable for sensitive skin types.
Antioxidant potential
May help protect skin from free radical damage caused by pollution and UV exposure, supporting a more youthful appearance over time.
Cons and cautions
Limited research
There is very little published scientific evidence specifically on acetylated Cupressus funebris wood extract, so its benefits are not as well-established as those of more common antioxidants.
Less common ingredient
Because it is not widely used, it can be harder to find in products, and there is less long-term safety data available compared to ingredients like vitamin C or green tea extract.
Best for
- Those looking for a gentle antioxidant ingredient
- People with sensitive skin who want to try a less common botanical extract
Use caution if
- Anyone with a known allergy to cypress or related conifer plants
Usage tips
Safety summary
