Dokollagen (Xanthium Strumarium Fruit Extract)
Dokollagen is a purified extract from the fruit of Xanthium strumarium, a cutting-edge botanical active ingredient with high biological potential. Its application in cosmeceuticals focuses on the modulation of the extracellular matrix and advanced cellular protection against photoaging.
Phytochemical Properties and Mechanisms of Action:
- Neocollagenesis Induction and Anti-Aging Effect: In vitro studies prove that the extract stimulates endogenous collagen synthesis and inhibits the enzymes responsible for its degradation (collagenases). It protects fibroblasts from damage caused by UVB radiation, preserving tissue elasticity.
- Neutralization of ROS (Reactive Oxygen Species): It features a high concentration of phenolic acids (caffeic and chlorogenic acids), providing potent antioxidant activity that mitigates oxidative stress and the subsequent protein carbonylation.
- Inflammatory Modulation and Healing: It has been shown to accelerate tissue repair in 3D epidermal models through the reduction of pro-inflammatory cytokines, validating its use in supporting reactive or acne-prone skin barriers.
- Complementary Cellular Photoprotective Effect: At optimized concentrations, it acts as a cellular survival agent against UVB-induced apoptosis.
- Focused Antibacterial Activity: Its active xanthanolides exhibit bacteriostatic efficacy against Staphylococcus aureus, offering a purifying action in formulations targeted at skin prone to cutaneous infections or acne.
- Formulation Synergy: It exhibits rheological and pharmacodynamic compatibility with hyaluronic acid.
