Ingredient review
Lignum Powder
INCI: LIGNUM POWDER
Lignum powder is a natural wood-based exfoliant that gently sloughs dead skin, but its particle size and source can affect how abrasive it feels.
In plain English
Lignum powder is simply very fine wood dust. In skincare, it acts like a gentle scrub—tiny particles help rub away dead skin cells when you massage a product onto your face or body. Because it comes from wood, the texture can vary from soft and powdery to slightly gritty, depending on how finely it's ground. It also helps absorb excess oil in powder formulations.

What it is
Lignum powder is a natural, biodegradable powder made by grinding wood (often from trees like pine, oak, or birch) into a fine particulate. It is used as a physical exfoliant and absorbent in cosmetics.
How it works
When applied to the skin, the irregularly shaped wood particles create friction that helps dislodge and remove dead skin cells from the surface. This mechanical exfoliation can improve skin texture and radiance. In powder products, it also soaks up excess moisture and oil, helping to mattify the skin.
Pros
Eco-friendly exfoliant
Unlike plastic microbeads, lignum powder is biodegradable and comes from renewable wood sources, making it a more sustainable choice for scrubs.
Oil-absorbing properties
In powder or mask formulas, lignum powder can help soak up excess sebum, leaving skin feeling less greasy throughout the day.
Cons and cautions
Inconsistent texture
Because it's a natural wood product, the particle size and sharpness can vary between batches, which may lead to unexpected scratchiness or irritation.
Not for sensitive skin
Even finely ground wood can be abrasive. If you have rosacea, eczema, or active breakouts, this ingredient might cause redness or micro-tears.
Best for
- People looking for a natural, biodegradable exfoliant
- Those with normal to oily skin who want a gentle scrub
Use caution if
- Individuals with sensitive, inflamed, or broken skin
- Anyone prone to micro-tears from harsh physical scrubs
Usage tips
Safety summary
Lignum powder is safe for most skin types when used as intended in rinse-off products. The main risk is physical irritation from overly coarse particles, so choosing finely milled versions and avoiding use on broken skin is recommended.
Research notes
There is limited published research specifically on lignum powder in cosmetics. Its safety is inferred from the long history of use of wood powders in traditional and natural skincare. Studies on other natural exfoliants suggest that particle size and shape are key factors in determining abrasiveness.
Common label clues
- Typical concentration
- 1–10% in rinse-off products; lower in leave-on
- Regulatory status
- Generally considered safe for cosmetic use in the EU and US when properly milled; no specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Scrubs, Masks, Powders
- Environmental note
- Lignum powder is biodegradable and sourced from renewable wood, but consumers should check if the wood comes from sustainably managed forests.
Good to know
- Lignum powder is sometimes labeled as 'wood powder' or 'sawdust' in ingredient lists.
- The source tree species can affect the powder's color and scent—for example, sandalwood powder has a distinct fragrance.
