Science

Mechanism of Action

This ingredient actively neutralizes free radicals, providing antioxidant defense against environmental stressors. It invigorates skin's natural processes by participating in the cellular energy-producing cycle, facilitating ATP synthesis via oxidative metabolism. Additionally, sodium succinate functions as a buffering agent, maintaining optimal pH within cosmetic formulations.

Key findings

  1. 01 Demonstrated a significant improvement in overall skin quality, increasing turgor and elasticity, enhancing hydration and color correction, and stimulating tissue regeneration. It also provided antioxidant effects by blocking free radicals and stimulating sluggish metabolic processes to reduce signs of aging.
  2. 02 Exhibited a positive tendency in lowering the expression of senescence markers in human dermal fibroblasts under high oxygen levels, suggesting potential geroprotective properties, although lower concentrations did not show beneficial effects on proliferation.
