Ingredient review
Piper Malacophyllum Oil
INCI: Piper Malacophyllum Flower/Leaf/Stem Oil
A fragrant essential oil from a tropical pepper plant, used mainly for scent in natural skincare, but with very limited research on skin benefits.
In plain English
This is an essential oil made from the flowers, leaves, and stems of a plant called Piper malacophyllum, which is related to black pepper. In skincare, it's mostly used to add a natural scent to products. Because it's an essential oil, it can be irritating for some people, especially if used in high amounts. There isn't much scientific research on how it specifically helps the skin, so its main role is fragrance rather than active treatment.

Common label clues
- Typical concentration
- Typically used at very low concentrations (under 1%) due to its potency as an essential oil.
- Regulatory status
- Generally recognized as safe for cosmetic use as a fragrance ingredient when used at low concentrations, but not specifically evaluated by the FDA for safety or efficacy.

Good to know
