RHODOMYRTUS TOMENTOSA FRUIT EXTRACT.

Valuable CAS - / HUMECTANT

This potent botanical extract precisely targets key factors in skin imbalance. It effectively rebalances the skin's microbiome by modulating Cutibacterium acnes, significantly reduces sebum production, and calms inflammation, promoting a clearer, more balanced complexion.

Summary

Antioxidant Anti-inflammatory Antimicrobial Sebum Regulator Skin-soothing Microbiome Balance Agent Oil Control

Science

Mechanism of Action

Rhodomyrtus Tomentosa Fruit Extract exerts robust antimicrobial activity against specific Cutibacterium acnes phylotypes, thereby modulating the dermal microbiota and inhibiting C. acnes proliferation to alleviate acne. It also regulates sebum production by inhibiting 5-alpha reductase and reducing lipid peroxidation, which contributes to diminished pore size, decreased shine, and balanced oil levels. Additionally, this extract possesses antioxidant properties, effectively scavenging free radicals, and demonstrates anti-inflammatory traits by suppressing cytokines, soothing erythema, and enhancing barrier function. It further offers photoprotective benefits, aiding in DNA repair and reducing UVB-induced inflammatory mediators.

Key findings

  1. 01 A 28-day clinical study utilizing a 2% concentration demonstrated a significant 41% reduction in skin sebum and a 21% reduction in redness among acne subjects. This application also favorably modified Cutibacterium acnes phylotype repartition, leading to a decrease in both retentional and inflammatory lesions.
  2. 02 Formulations containing rhodomyrtone, a key compound within the extract, effectively reduced acne lesions and inflammation, showing comparable efficacy to clindamycin without inducing skin irritation or microbial resistance.
  3. 03 A cream incorporating 5 wt% of a combination extract, including Rhodomyrtus Tomentosa, significantly improved facial acne and redness over a 28-day period in 30 subjects with sensitive and acne-prone skin.

Dusting Analysis

Not commonly dusted

Clinical studies confirm significant efficacy at concentrations as low as 2%, with effective application up to 5%. This data suggests that using sub-efficacious concentrations below this range would not yield the observed benefits.
