Ingredient review
Murumuru Seed Powder
INCI: Astrocaryum Murumuru Seed Powder
A gentle, natural physical exfoliant that sloughs off dead skin cells without harsh microbeads.
In plain English
Murumuru seed powder is made by grinding the seeds of the murumuru palm tree into a fine powder. When used in scrubs or cleansers, the tiny particles help manually buff away dead skin cells, leaving skin smoother and brighter. Because the particles are rounded and not too sharp, it's considered a gentler alternative to some harsher scrubs like walnut shell powder.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A powdered exfoliant made from the dried and ground seeds of the murumuru palm (Astrocaryum murumuru), a tree native to the Amazon rainforest.
How it works
The fine, irregularly shaped particles create gentle friction when massaged onto the skin, helping to dislodge and remove dead skin cells, dirt, and excess oil from the surface. This mechanical exfoliation can improve skin texture and radiance.
Pros
Eco-friendly exfoliant
Made from a renewable plant source, it avoids the environmental concerns of plastic microbeads.
Gentle on skin
The seed particles are relatively fine and rounded, making them less likely to cause micro-tears compared to crushed nutshells.
Cons and cautions
Not for sensitive skin
Even gentle physical exfoliants can irritate if you have rosacea, eczema, or very reactive skin.
Risk of over-exfoliation
Using a scrub with this powder more than 2–3 times a week can strip the skin barrier and lead to redness or dryness.
Best for
- People looking for a natural alternative to plastic microbeads
- Those with normal to oily skin who want gentle physical exfoliation
Use caution if
- Individuals with active acne, eczema, or very sensitive skin
- Anyone with open wounds or sunburned skin
