Coffee powder

Coffee powder is the ground seed of Coffea arabica, declared as an abrasive in CosIng1. It is not caffeine, which is an isolated molecule. Data specific to the powder are rare: one study on spent coffee grounds scrubs measures skin barrier tolerance2, and the reviews on cosmetic coffee rely mostly on laboratory work34.

What the research says

Each result shows the protocol and the level of evidence. The higher the level, the better the result carries over to a finished formula.

Clinical trialReview or consensusLaboratory

SkinSkincare

A spent coffee grounds scrub: the base matters as much as the powder

Clinical trial
Spent coffee grounds at 5% and 10% in 7 scrub basesConsumer test, then water loss measurementSample size and duration not given in the abstract

The ointment-based scrub showed no significant change in the skin barrier. The aqueous scrubs (cream and gel at 5%) disrupted it temporarily, with full recovery within 6 h after a hand cream2.

Antioxidant effects mostly in the laboratory

Review
2026 reviewExtracts of coffee beans, leaves, fruit and grounds

In the laboratory, the extracts show antioxidant, anti-aging and photoprotective activities. In humans, trials are small and short, with modest improvements in hydration, elasticity and barrier function. The authors judge the evidence insufficient to make these products an evidence-based reference3.

Caffeine, chlorogenic acids and flavonoids

Review
2025 reviewLeaves and beans of Coffea arabica

The review lists caffeine, chlorogenic acids and flavonoids. The leaves contain more of some phenolic compounds than the beans. The authors call for clinical trials to validate the benefits4.

Alternative to microplasticsEnvironment

Plastic microbeads, at the heart of dermatology reviews

Review
2026 reviewPersonal care products and pollution

The review examines intentionally added microbeads, microplastics released by packaging and substances of concern in personal care products, then makes recommendations to reduce the impact5.

The industry is removing microplastics from its formulas

Review
2024 reviewRestrictions by world region

Formulators are adapting their products to current and future legislation aimed at eliminating microplastics. The review also describes sustainable solutions to replace them6.

A European restriction on synthetic microparticles

Regulation
Regulation (EU) 2023/2055REACH Annex XVII

Regulation (EU) 2023/2055 adds to REACH a restriction on synthetic polymer microparticles, with phased information obligations. A substance being natural is among the criteria that allow it to be excluded from the definition7. A ground seed powder is a plant material; the exact scope and timelines by product type should be checked in the text of the regulation.

This page summarizes published literature on a cosmetic ingredient. It does not describe the effect of a finished product, which depends on its formula, and it is not medical advice. We found no controlled trial on coffee powder alone. The reviews cited mostly cover coffee extracts, not the exfoliating powder: their results do not transfer to a scrub.

Which products use coffee powder?

Our white label catalog includes 4 formulas with coffee powder: the key active in 3 of them, a supporting ingredient in the others. Every category can be customized (formula, fragrance, packaging).

4Hair

Scalp scrubs and detox pre-shampoo scrub, where the exfoliating coffee powder is often paired with caffeine.

In our formulas, it is most often paired with

Frequently asked questions about coffee powder

What is coffee powder?
It is the dried, ground seed of the arabica coffee plant, declared in cosmetics as COFFEA ARABICA SEED POWDER (CAS 84650-00-0). CosIng gives it a single function: abrasive1. It exfoliates mechanically, mostly in scrubs.
What is the difference between coffee powder and caffeine?
Coffee powder is a ground plant material that exfoliates. Caffeine is an isolated molecule, declared as CAFFEINE, with its own functions11. A scrub can contain both: ground coffee acts as the abrasive, and caffeine is added separately, as in several of our formulas. Caffeine has its own page.
Is a coffee scrub suitable for all skin types?
Not necessarily. In the study on spent coffee grounds scrubs, the base changed the result: the ointment did not change the skin barrier, while the aqueous bases disrupted it until recovery within 6 h2. No trial targets sensitive skin or the face. Tolerance is checked on the finished product.
How do you replace the plastic microbeads in a scrub?
With plant powders such as ground coffee or apricot kernel, or with other natural exfoliants. The reviews describe the gradual removal of microplastics from formulas65. Regulation (EU) 2023/2055 restricts synthetic polymer microparticles in REACH7: the timeline that applies to your product type should be checked in the text.
What particle size should you choose for a coffee powder?
The sources we retained give no particle size, and we put none forward. It is set during formulation and checked by sieving, with the supplier's technical data sheet. In practice, our catalog uses a fine powder for the face and ground coffee for the body.
Can you use spent coffee grounds?
The 2025 study worked on spent grounds, after characterization, formulation and stability tests2. For production, ask for analyses of each batch: grounds are a raw material whose quality varies.
Can you manufacture a coffee scrub for my brand?
Yes. Our ISO 22716 certified lab offers 4 coffee formulas (face, body and scalp scrubs) that you can customize, or a custom formula. Samples are free.
