Science
Mechanism of Action
This ingredient operates at a cellular level, fortifying the skin's natural barrier and optimizing moisture retention to diminish the appearance of fine lines. It actively stimulates collagen production, specifically boosting COL-I expression, which is crucial for maintaining skin firmness and elasticity. Its potent antioxidant capacity neutralizes free radicals, offering robust protection against damage from UV radiation, pollution, and blue light. Furthermore, it suppresses inflammatory responses, promotes skin regeneration, and regulates genes essential for healthy skin barrier formation. Key active components, such as leontopodic acid A, also hinder matrix metalloproteinase-1 (MMP-1) activity and curb reactive oxygen species (ROS), while potentially activating Sirtuins, proteins linked to cellular longevity.

Key findings
- 01 Demonstrated a 60.37% increase in cell viability when exposed to oxidative stress (hydrogen peroxide). In vivo, it significantly improved periorbital wrinkles, skin elasticity, dermal density, and skin thickness.
- 02 Effectively inhibited MMP-1 production and promoted COL-I secretion in human foreskin fibroblasts, illustrating protective effects against blue light-induced damage. A concentration of 2 mg/mL also stimulated fibroblast proliferation.
- 03 Provided a tensor and smoothing restorative effect on aged skin, particularly beneficial for addressing sagging neck skin and the tear trough area.
- 04 In-vivo trials reported a reduction in neck sagging by -10.6% to -56% within three weeks. After six weeks, crow's feet wrinkles were visibly smoothed, with surface area reductions of -11% to -75%.
