Science
Mechanism of Action
This extract operates through multiple precise mechanisms to benefit the skin. It inhibits Matrix Metalloproteinase-1 (MMP-1) activity, which is crucial for collagen degradation, thus potentially reducing the appearance of fine lines, wrinkles, and improving skin elasticity. Furthermore, by inhibiting tyrosinase activity, it contributes to a reduction in melanin synthesis, thereby diminishing hyperpigmented areas such as freckles, melasma, and promoting a more even skin tone. For oily skin, it can help regulate sebum production via lipoxygenase activity inhibition. Its inherent properties also provide significant hydration and a soothing effect, effectively reducing redness and irritation.

The Formula
Formulation
Stability
The ingredient exhibits optimal stability in a slightly acidic range. A hydroethanolic extract of Nopalea Cochenillifera has a measured pH of 4.50 ± 0.04, while its cladodes flour maintains a pH of 5.1 ± 0.06. Related Opuntia species are noted for stability across a broader pH range of 4.0 to 7.0, with fruits often naturally presenting a low pH (3.7–4.5) which aids in preservation.
Safety
Safety Profile
Preclinical safety assessments in rats, involving oral administration of Nopalea Cochenillifera extracts at doses up to 2000 mg/kg, demonstrated no signs of acute toxicity, mortality, or significant changes in biochemical and hematological parameters. In vitro assays further confirmed the absence of cytotoxicity.
