Subcutaneous fat reduction (topical)

Mixed Evidence

Mostly animal and cosmetic-industry data suggest a modest topical effect on fat cells. Human evidence is preliminary.

How it works

Cirsium oligophyllum extract contains flavonoids and phenolic acids. Small in vitro and animal studies suggest the extract may inhibit lipid accumulation in adipocytes and reduce subcutaneous fat in mice. Some Japanese cosmetic and supplement formulations use it as a slimming ingredient, but human clinical evidence is limited.

Dosage

No standardized human dose is established. Commercial topical formulations contain 0.1 to 1 percent extract.

When and how to take it

No evidence-based timing is established for oral use. Topical applications are typically used twice daily per product instructions.
