CISTANCHE TUBULOSA ROOT EXTRACT.

Valuable CAS - / ANTIOXIDANT

A potent botanical extract derived from the 'Desert Hyacinth,' rich in phenylethanoid glycosides and polysaccharides that target structural integrity and cellular defense. It functions as a multi-dimensional rejuvenator by supporting the skin's natural collagen matrix while providing significant antioxidant protection against photoaging.

Antioxidant Collagen Support Skin Brightening Humectant UV Protection Booster

Science

It operates through a synergistic blend of echinacoside, acteoside, and D-mannitol. These compounds modulate tyrosinase activity to regulate melanin synthesis and stimulate the endogenous production of hyaluronic acid and hydroxyproline. Additionally, its polysaccharides neutralize oxygen radical chains and enhance superoxide dismutase (SOD) activity, effectively shielding the skin matrix from UVB-induced degradation.

Key findings

  1. 01 Demonstrated significant up-regulation of hyaluronic acid synthesis and maintenance of the skin matrix through collagen metabolism biomarkers.
  2. 02 Identified as a selective apoptotic agent for melanoma cells with an IC50 of 2500 µg/ml while remaining inert on healthy non-tumor cells.
  3. 03 Phenethyl alcohol glycosides effectively modulated mRNA transcription to inhibit UVB-induced hyperpigmentation and even out skin tone.

Stability

The component verbascoside is highly thermosensitive, retaining only 41.6% activity after 4 hours of heat exposure; cold-processing is recommended. However, dried extracts show excellent long-term stability, maintaining phenylethanoid levels for up to 48 months at 25°C.
