BACKGROUND
The fermented leaves and stems of Cyclopia intermedia are used to brew honeybush tea, an herbal tea indigenous to South Africa with reported anti-wrinkle effects. Wrinkle formation caused by photoaging clearly involves changes in extracellular matrix components and mechanical properties of the skin.
METHODS
The inhibitory effects of honeybush extract and fermented honeybush on wrinkle formation were determined by analyzing skin replicas, histologically examining epidermal thickness, and identifying damage to collagen fibers.
RESULTS
Honeybush extract and fermented honeybush reduced the length and depth of skin winkles caused by UV irradiation and inhibited thickening of the epidermal layer, in addition to suppressing collagen tissue breakdown reactions, indicating its potential use as a skin wrinkle prevention agent.
CONCLUSIONS
This in vivo study demonstrates that honeybush produces significant anti-wrinkle effects and is therefore of interest in anti-aging skin care products.
