Science
Mechanism of Action
This extract primarily functions as an antioxidant, actively reducing free radical damage (demonstrated by a 54.84% ± 0.57% DPPH radical scavenging activity at an IC50 of 25.2 µg/mL for a crude methanolic extract) and safeguarding skin proteins to help restore natural radiance. Its robust antibacterial and antifungal properties, largely attributed to carvone, target acne-related bacteria, help manage body odor, and combat fungal infections. Furthermore, it provides anti-inflammatory relief for red, swollen, and itching skin and acts as an astringent to minimize pore visibility and tighten skin. Compounds such as menthol, myrcene, and caryophyllene contribute to its antiseptic qualities, aiding in wound care and preventing infections.

Key findings
- 01 A topical solution combining Berberis integerrima root extract and spearmint essential oil significantly reduced acne lesions and Modified Global Acne Grading Scale (mGAGS) scores, comparable to topical clindamycin. The specific concentration of the spearmint component was not detailed for the extract, only its use as an essential oil in a combination product.
- 02 A crude methanolic extract of Mentha spicata showed a DPPH radical scavenging activity of 54.84% ± 0.57% with an IC50 value of 25.2 µg/mL, indicating antioxidant properties.

Safety Profile
Mentha Spicata Crispa Herb Extract is generally considered safe for cosmetic use, with toxicological investigations on Mentha spicata showing overall safety at various doses. However, specific CIR assessment for 'MENTHA SPICATA CRISPATA HERB EXTRACT' is unavailable. Spearmint essential oil, related to this extract, can induce skin sensitivities, irritation, or a burning sensation, particularly when undiluted; therefore, a patch test is advisable. Pregnant individuals are cautioned against using spearmint essential oil due to its emmenagogue properties, suggesting a precautionary avoidance for the extract as well.
