INCI: Cassia Nomame Leaf/Stem Powder

A gentle botanical powder that may offer antioxidant and soothing benefits, but research is limited and mostly based on traditional use.

In plain English

Cassia nomame leaf/stem powder is made by grinding the leaves and stems of a plant related to senna. In skincare, it's used as a mild exfoliant or to deliver plant compounds that may calm redness and fight free radicals. Because it's a natural powder, it can also help absorb excess oil. However, there isn't much modern scientific research on this specific ingredient, so its benefits are mostly inferred from similar plants.

Score terms in plain English

Irritation risk

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

emerging

The ingredient may be promising, but claims should be treated more cautiously.

What it is

A finely ground powder derived from the leaves and stems of Cassia nomame, a plant in the Fabaceae family. It contains natural fibers, flavonoids, and other phytochemicals.

How it works

When applied to the skin, the powder can provide gentle physical exfoliation by sloughing off dead skin cells. The plant compounds may also act as antioxidants, helping to neutralize free radicals that cause premature aging. Some compounds in Cassia species have shown soothing properties in traditional medicine.

Pros

Gentle physical exfoliation

The fine powder texture can help remove dead skin cells without harsh microbeads, making it suitable for sensitive skin when used sparingly.

Natural oil absorption

As a powder, it can help mattify the skin and reduce excess sebum, which is beneficial for oily or acne-prone skin types.

Cons and cautions

Limited scientific backing

There are very few peer-reviewed studies on Cassia nomame specifically for skincare, so most claims are based on traditional use or related species.

Potential for over-exfoliation

If used too often or in high concentrations, the powder can be abrasive and lead to micro-tears or irritation, especially on sensitive skin.

Best for

People looking for a gentle, natural exfoliant
Those with oily or combination skin who want a powder that can absorb shine

Use caution if

Individuals with very dry or compromised skin barriers
Anyone allergic to plants in the Fabaceae family (e.g., peanuts, soy)

Usage tips

Mix a small amount with water or a gentle cleanser to form a paste before applying to the face.

Use no more than 1-2 times per week to avoid over-exfoliation.

Always patch test first, especially if you have sensitive skin or allergies to legumes.

Safety summary

Cassia nomame leaf/stem powder is considered low-risk for most people when used as directed. The main concerns are potential allergic reactions in those with legume allergies and physical irritation from overuse. Always patch test and follow product instructions.

Research notes

Research on Cassia nomame in cosmetics is minimal. Most evidence comes from traditional use and studies on related Cassia species, which show antioxidant and anti-inflammatory potential. More specific studies are needed to confirm benefits for this exact ingredient.

Common label clues

Typical concentration: 0.1% to 2% in leave-on products; up to 5% in rinse-off products
Regulatory status: Generally recognized as safe for cosmetic use in the US and EU when sourced from reputable suppliers. No specific restrictions known.
Common uses: Face masks, Cleansers, Exfoliating powders
Environmental note: Cassia nomame is a plant that can be cultivated, but sustainability depends on farming practices. Look for brands that source from responsible growers.

Good to know

Cassia nomame is sometimes confused with other Cassia species used in traditional medicine, but it is not the same as senna used for laxatives.
The powder may have a slight earthy scent that can be masked by other ingredients in a formulation.
