Science
Mechanism of Action
This extract operates through multiple pathways to rejuvenate skin. It actively stimulates the production of vital structural proteins like collagen (COL1A1, COL3A1) and elastin, which are crucial for maintaining skin firmness and flexibility. Its rich composition of antioxidants, including myconoside, paucifloside, flavonoids, and phenolic acids, provides comprehensive protection against oxidative damage from UV radiation and pollution. Furthermore, it safeguards mitochondrial health, preserves fibroblast morphology, modulates cellular stress responses by maintaining glutathione levels, and possesses anti-inflammatory properties due to components like hispidulin, all contributing to delayed cellular senescence and enhanced epidermal regeneration.

Key findings
- 01 In human volunteers, a 3% concentration significantly improved skin elasticity by 300% (P < 0.0002) and skin radiance by 400% (P < 0.05) after 15 days, with these benefits sustained through 30 and 60 days. It also provided 100% protection against UV-induced dermal oxidation (P < 0.01) in human skin biopsies.
- 02 In vitro studies on human dermal fibroblasts demonstrated that these concentrations preserved fibroblast morphology, enhanced mitochondrial mass, and upregulated collagen-related gene expression (COL1A1, COL3A1).
- 03 In vitro testing revealed that these concentrations were most effective in protecting against oxidative stress induced by H2O2 and maintaining glutathione content closer to normal levels in HeLa cancer cells.

Dusting Analysis
The clinically studied concentration of 3% for significant in-vivo results is a robust active level, suggesting that this ingredient is not commonly used at ineffective 'dusting' percentages in formulations aiming for efficacy.
The Formula
Formulation
Stability
This extract is water-soluble and is often supplied in a glycerin base. It is a natural, biodegradable ingredient that can be formulated without traditional preservatives.
Safety
Safety Profile
Haberlea Rhodopensis Leaf Extract is generally considered safe for topical application, with adverse reactions being uncommon. In vitro studies indicate a lack of significant cytotoxic effects at concentrations up to 50 mg/ml and good biocompatibility with minimal genotoxic effects. However, data regarding its topical usage during pregnancy and breastfeeding are limited; individuals in these categories should consult a healthcare professional before use. A patch test is recommended prior to widespread application.
