Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.

What it is
Murumuru seed butter is a vegetable butter cold-pressed from the seeds of the Astrocaryum murumuru palm, native to the Amazon basin. It is rich in fatty acids (especially oleic and lauric acids) and vitamins A and C.
How it works
When applied to the skin, the butter melts at body temperature and spreads easily. Its fatty acids help fill the spaces between skin cells, reinforcing the skin's natural barrier and locking in moisture. This reduces water loss and leaves the skin feeling smooth and supple.
Pros
Lightweight feel for a butter
Unlike some heavy butters, murumuru absorbs quickly and leaves a soft, non-greasy finish, making it comfortable for daily use on the body and even the face for dry skin types.
Rich in skin-friendly fatty acids
It contains lauric, myristic, and oleic acids, which help strengthen the skin barrier and improve moisture retention, especially beneficial for dry or compromised skin.
Cons and cautions
May not suit oily skin
While lighter than many butters, it is still a rich emollient. People with very oily or acne-prone skin might find it too heavy for the face, potentially clogging pores if used in excess.
Sustainability concerns
As a wild-harvested Amazonian palm product, murumuru butter's sustainability depends on ethical sourcing and fair trade practices. Not all suppliers guarantee these standards.
Best for
- People with dry, dehydrated, or flaky skin
- Those looking for a natural, plant-based moisturizer for body or hair
Use caution if
- Individuals with very oily or acne-prone skin may prefer lighter oils or lotions
