Summary

Skin Conditioning Anti-inflammatory Hair Growth Reduction Skin Brightening Antimicrobial Antioxidant Moisturizing

Science

Mechanism of Action

This extract functions as a broad-spectrum skin conditioner. Its anti-inflammatory action involves mitigating inflammatory enzyme activity, reducing swelling, and curbing cellular infiltration and keratinocyte hyperproliferation. For hair reduction, the oil's flavonoids are posited to inhibit androgens and slow down hair-growth enzymes. It delivers antioxidant protection through its rich profile of volatile oils, terpenoids, saponins, and flavonoids, while also demonstrating antimicrobial efficacy against various bacteria (e.g., Staphylococcus aureus) and fungi (e.g., Candida albicans). Additionally, it promotes skin brightening by inhibiting tyrosinase activity and supports hydration without pore occlusion, enhancing the skin's natural defense for a calming effect.

Key findings

  1. 01 Topical application demonstrated efficacy comparable to Alexandrite laser in reducing unwanted axillary hair (both dark and white), with statistically significant differences in decreasing white hair growth. No side effects were detected.
  2. 02 Exhibited anti-inflammatory and analgesic effects comparable to hydrocortisone in managing post-laser hair removal pain and erythema.
  3. 03 Reduced ear edema and cellular infiltrate in acute and chronic skin inflammation models in mice, and decreased TPA-induced keratinocyte hyperproliferation. An ethanol extract contained 45 μg/g of chlorogenic acid.
  4. 04 Showed depigmenting effects on keratinocytes by inhibiting tyrosinase activity, addressing axillary hyperpigmentation.
  5. 05 Extracts displayed strong antimicrobial activity at concentrations of 100 mg/ml against various microorganisms, and at 12.5 mg/ml specifically against Bacillus subtilis.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Low

While a manufacturer indicates a low-risk profile (risk factor 1) and deems the extract non-comedogenic and generally safe for pregnant women, the Cosmetic Ingredient Review (CIR) has not yet reviewed this ingredient. The Good Scents Company identifies no GHS hazard classifications for the extract but notes that oral, dermal, and inhalation toxicity data are undetermined. Importantly, cautionary advice regarding *Cyperus oil* suggests potential safety concerns for large or high-absorption areas due to limited data, possible interaction with androgen receptors, and a plausible risk of inducing cancer. These specific warnings are for the *oil*, not explicitly the *root extract*, necessitating careful consideration of concentration and formulation.
