OPUNTIA HUMIFUSA STEM POWDER.

Valuable / SKIN CONDITIONING - MISCELLANEOUS

Opuntia Humifusa Stem Powder, derived from the Korean Cheonnyuncho cactus, is a resilient botanical ingredient prized for its multi-faceted benefits. It provides extensive hydration, calms irritated skin, and delivers potent antioxidant protection, making it a valuable asset for maintaining skin health and combating environmental stress.

Summary

Skin Conditioning Antioxidant Soothing Hydration Anti-aging Anti-inflammatory Collagen Synthesis Support Hyaluronic Acid Synthesis Stimulation Photoprotection

Science

Mechanism of Action

This ingredient functions by directly addressing skin irritation and redness through the modulation of stress markers associated with sensory nerve cells. Its robust antioxidant capacity is attributed to a high concentration of polyphenols, flavonoids, and piscidic acid, an iron chelator, which collectively neutralize free radicals and shield the skin from environmental aggressors. Additionally, it enhances the skin's total antioxidant defense system and actively stimulates the synthesis of hyaluronic acid, thereby promoting deep hydration and bolstering protection against photodamage. Empirical data also confirms its significant anti-inflammatory capabilities.

Key findings

  1. 01 In a systematic review and meta-analysis, Opuntia humifusa extracts, at concentrations of 100-500 µg/mL, demonstrated beneficial anti-aging effects in both in vitro and in vivo models, including enhanced collagen synthesis. These extracts were confirmed non-toxic to normal human cells and effectively mitigated particulate matter-induced oxidative stress and inflammation in the skin.
  2. 02 An extract of Opuntia humifusa (OHE) was shown to significantly upregulate Hyaluronic Acid Synthase (HAS) expression, consequently increasing hyaluronic acid (HA) synthesis in photo-damaged human keratinocytes. Furthermore, in UV-irradiated hairless mice, OHE suppressed increases in HA and related proteins, reduced transepidermal water loss, and diminished erythema, indicating substantial protection against UVB-induced photodamage.

Stability

The ingredient exhibits a slightly acidic profile, with a measured pH range between 5.07 and 5.34. Optimal stability in cosmetic formulations is likely best maintained within or closely around this pH range. Its inherent mucilage and soluble dietary fiber content suggest excellent water uptake and dissolution properties. Specific long-term stability data for formulated cosmetic products are not explicitly available.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has not formally assessed Opuntia Humifusa Stem Powder. However, Opuntia species are widely consumed as food and are generally recognized as safe. Studies confirm that Opuntia humifusa treatments are non-toxic to normal human cells. While the raw plant contains irritating glochids, cosmetic-grade powder and extract forms undergo processing to ensure these irritants are effectively removed, minimizing sensitization risk.
