Science
Mechanism of Action
This extract, abundant in chlorogenic acid, gallic acid, and various polyphenols, exhibits potent antioxidative properties, comparable to vitamin C. It actively combats skin aging by inhibiting key enzymes—hyaluronidase, collagenase, and elastase—responsible for degrading essential extracellular matrix components. Critically, it supports perlecan and its receptor, dystroglycan, within the dermal-epidermal junction (DEJ), normalizing intercellular communication often disrupted by aging. This action enhances skin homeostasis, reinforces DEJ structure, and improves capillary strength, while also mitigating inflammation via redox signaling and NF-κβ pathways, providing a soothing effect.

Key findings
- 01 An in-vitro test on human keratinocytes demonstrated a 32% reduction of oxidative stress within living cells.
- 02 Supplier research indicates that at these concentrations, the extract supports perlecan and dystroglycan, crucial DEJ components, for normalized communication, visibly reviving radiance, restoring a smoother surface, and softening the appearance of lines and wrinkles.
- 03 Clinical studies (for Perlaura™, a specific extract) confirm improved radiance, texture, and complexion, along with significant reduction in multiple wrinkle attributes, achieved by reinforcing DEJ structure, improving capillary strength, and aiding basal membrane repair.

The Formula
Formulation
Stability
While generally non-irritating, the ingredient's phenolic compounds benefit from encapsulation to enhance solubility, functionality, and shelf life. It is frequently supplied as a liquid pre-combined with glycols. The risk of irritation may increase when formulated with other known problematic ingredients.
Safety
Safety Profile
Cosmetic ingredients in the U.S. do not require FDA pre-market approval; safety assurance is the manufacturer's responsibility. No specific CIR or SCCS assessment was found. Oral toxicity studies in mice (LD50 ~142.82-200 mg/kg) and rats (LD50 >7g/kg) indicate low acute toxicity via ingestion. EWG rates its allergy and immunotoxicity risk as 'LOW'.
